GREETINGS FROM THE ECPE PRESIDENT PROF. DR. LEO LORENZ

Dear ECPE Members and Guests,

I am very happy to welcome you studying

the new ECPE Network Brochure 2014.

This brochure will give you an insight

and overview on the various network

activities and services for our members

e.g. the ECPE Workshops and Tutorials,

the research projects and technology

studies as well as the recently started

Roadmap Programme ´Power Electronics

2025 . But first of all our Network

members, Industrial Members and

Competence Centres, introduce

themselves with their key products

respectively research activities as well as

the contact person in the ECPE Network.

Power Electronics, as the technology

associated with the efficient conversion,

control and conditioning of electric

energy from the source to the load, is

driving the megatrends of our modern

society e.g. Energy Efficiency, Renewable

Energies and E-Mobility. In our network

strategy paper ´ECPE 2020 – Objectives

and Future Challenges´ we have defined

the power electronics megatopic for the

next decade which is Electronic Power

Grids for efficient and sustainable power

generation, distribution and consumption.

As an industry-driven research network

with about 150 member organisations,

comprising Member companies and

Competence Centres, ECPE is a preferred

partner and contributes significantly

to the technical contents of major

power electronics conferences in

Europe and represents this discipline at

engineering societies and governmental

organisations. In close cooperation

between expert teams of our Industrial

Members and Competence Centres, we

are accepted and highly experienced

to initiate and execute research and

technology studies on key future research

directions. We run a pre-competitive

joint research programme, develop

technology roadmaps and, on a regular

basis, we invite top experts to discuss the

application of new SiC and GaN device

technologies in an open forum. We have

established industry-students contact

platforms to interlink with companies at

an early stage of their studies, initiated

the ECPE Young Engineer Awards and

co-organise the European PhD School.

I hope our ECPE Network Brochure will

provide you with valuable information

and an insight view of questions related

to power electronics, inspiring you to visit

one of our ECPE events or even to join

the Network as a member. I am very sure

that your membership will strengthen

power electronics initiatives and activities

in Europe and you will benefit from all

the results we are jointly achieving.

Let us shape European industrial needs,

research directions and academic

education in a strong power electronics

community. ECPE is open to provide the

knowledge base platform and interlink

industry, science and public organisations.

1.5 ECPE NETWORK AFTER 10 YEARS

Development of the ECPE Member

Portfolio since the Foundation of the

Network in 2003

Competence Centres

Member Companies

Number of Members

On 17 April 2013 our ECPE Network

celebrated the 10 Years Anniversary

in Nuremberg with representatives

from ECPE Member Companies and

Competence Centres as well as with

invited guests from Japan and US.

In conjunction with the anniversary

session, an ECPE Network Symposium

´Power Electronics Research in Europe

and Beyond´ was held with renowned

experts from the international power

electronics research community e.g.

Prof. F. Blaabjerg (Aalborg University),

Prof. R. de Doncker (RWTH Aachen),

Prof. J.W. Kolar (ETH Zurich),

Prof. I. Omura (Kyushu Institute of

Technology) and Prof. D. Boroyevich

(Virginia Tech).

Over these 10 years our European

Network for Power Electronics has been

growing very successfully. Starting from

eight founder members, ECPE has grown

up to an acknowledged European

Research Network comprising more than

70 member companies and about the

same number of Competence Centres

from universities and research institutes.

10

The ECPE Workshops are addressing a

wide range of up-to date topics along

the innovation and value chain of power

electronics from materials, components

and converter topologies up to

application-related topics in various

application fields of power electronics

2.1 ECPE WORKSHOPS

2. ECPE NETWORK SERVICES

e.g. in automotive, industrial drives,

renewable energies and electronic

power grids. These Workshops provide

a unique platform for networking talks

and expert discussion. A typical ECPE

Workshop is a two-day event with

about 15-20 invited speakers from

academia and industry, sometimes

complemented by a panel discussion.

The majority of participants comes

from industry especially from the ECPE

Member companies but also the ECPE

Competence Centres use these events to

discuss results from their latest research

with industry experts. The number

of participants varies from 50 to 150

depending on the topic, the workshop

locations are spread over Europe. The

details regarding topics, dates and

locations are available in the ECPE

Calendar of Events on our web site.

11

While the Workshops are mainly

focussing on expert discussion, the

ECPE Tutorials are addressing education

and training with the target group of

young engineers in industry. The number

of participants is normally limited to

35 persons to keep the classroom

atmosphere. A typical ECPE Tutorial is a

two-day event involving a team of 2-4

course instructors. The portfolio of ECPE

Tutorials is covering the basic topics and

disciplines of power electronics: power

semiconductor technologies and devices,

power electronics packaging, parasitics &

EMC, reliability and thermal engineering.

An ECPE certificate is given to those

participants who attended all five basic

tutorials.

2.3 INFORMATION ON EUROPEAN RESEARCH & DEVELOPMENT PROJECTS


There are several programmes and

initiatives on the European R&D stage

funding research projects related to

power electronics. Apart from the

European Commission with its

framework programme Horizon 2020

and the European EUREKA initiative with

the CATRENE and EURIPIDES clusters

there are Joint Undertakings (JU) and

Joint Technology Initiatives (JTI) working

as public-private partnership e.g. ENIAC,

ARTEMIS, ECSEL, FUEL CELL &

HYDROGEN and CLEAN SKY.

From the hundreds of research projects

on European level ECPE is selecting those

projects with relevance to power

electronics and presenting compact

project information on the ECPE web site

with the project title, abstract,

consortium, project volume and duration

together with a link to the project web

site, if available. The aim of this project

overview is to provide a higher level of

transparency on what is going on in

power electronics research on the

European level.

Unfortunately, none of these

programmes and initiatives is directly

addressing power electronics e.g. in the

headline.

European PhD School

The European PhD School on ´Power

Electronics, Electrical Machines,

Energy Control and Power Systems´

was founded in 1999 with the goal

of providing PhD students with the

opportunity to broaden their knowledge.

About 100 PhD students from all over

Europe take part every year. ECPE is

responsible for organising the Industry

Day with companies exhibition for

recruitment.

ECPE Job Forum

In the Job Forum on the ECPE web site

network members have the possibility

to search for young power electronics

engineers Europe-wide. In addition, there

is a separate rubric for student positions

at the ECPE Member companies e.g.

for practical trainings, master thesis or

working students. This network service is

free of charge.

2.5 ECPE AT EUROPEAN CONFERENCES AND EXHIBITIONS


Power Electronics Conferences in

Europe

ECPE is involved in several conferences

with reference to power electronics

as co-organiser or technical sponsor.

With its engagement ECPE wants

to strengthen the visibility of power

electronics as well as the role und

influence of European industry in these

important conferences in Europe.

In the case of two conferences, the

International Conference on Integrated

Power Electronic Systems (CIPS) and

the International Conference on Power

Electronics and Intelligent Motion (PCIM

Europe), ECPE is sponsoring the Young

Engineer Award.

3.1 ECPE ROADMAP PROGRAMME

3. ECPE PROJECTS AND INITIATIVES

Research and Technology Roadmaps are

an important strategic tool to identify

and guide a mainstream for medium

to long term research. The ´Power

Electronics 2025´ Roadmaps will be

the key element of the ECPE Strategic

Research Agenda. The roadmaps are

used by the ECPE Network members for

different purposes:

Provide input and industrial guidance

to research programmes on European

as well as on national level

ECPE Member companies will reflect

their own company roadmap vs. the

ECPE roadmaps

ECPE Competence Centre will use

the roadmaps when they define new

research directions

Based on the experiences from the

1st ECPE Roadmap Programme (2007-

2010) the Roadmap 2.0 Programme is

structured in three application-related

groups:

1. Power Supplies (low power)

2. Automotive & Aircraft

(medium power)

3. Electronic Power Grid (high power)

In these three groups also technology-

related trends e.g. wide bandgap

power semiconductors and advanced

integration technologies are discussed

but against the background of the

specific system and application field.

17

ECPE Wide Bandgap User Forums

have established as an international

event where users - i. e., engineers

developing advanced power electronic

converters - and manufacturers of

Silicon Carbide (SiC) and Gallium Nitride

(GaN) devices meet biannually for a

fruitful exchange. The 5th SiC & GaN

User Forum took place in Munich in

May 2013. The main technical focus has

been on new developments with SiC

and GaN transistors including related

aspects like circuit design and packaging.

Renowned experts from all over the

world have been invited to explain state

of the art and trends, to foster physical

understanding, to in depth explain

their research and development work

in technical presentations and to share

their knowledge in discussions. The

User Forum this way has established a

platform to share experience and ideas,

to discuss and find out which power

electronic systems are predestinated

for usage of SiC or GaN, how to

appropriately design-in those novel,

almost ideal but also challenging

components, and which open issues

need to be addressed. It aimed at finding

and pointing out approaches to exploit

the high potential of those devices and

to support their beneficial introduction in

power electronic systems.

3.2 SIC & GAN USER FORUM

In conclusion, system and device related

research and development have led to

remarkable results: With SiC diodes

being already established in industrial

applications, SiC transistors can be

expected to follow soon in a rather

broad power range. Circuit designers

will like the fact that there are still

various solutions, i. e., types of devices.

GaN transistors are subject to device

and application development; they may

compete with SiC devices starting in the

lower voltage range, i. e. with blocking

voltages around 600 V. Advances in

packaging as required especially with

respect to minimised parasitics, have

been reported on product and research

level and need to go on. This also applies

to necessary qualification of reliability

and robustness.

18

The 1st decade of the ECPE Network

(2003 - 2013) was affected by the

energy-related megatrends of energy

efficiency, renewable energies and

e-mobility. At that time ECPE has started

a strategic process to communicate the


by stressing the user´s value and benefit

as well as the societal impact. The potential

of power electronics for energy saving

and improvement of energy efficiency

has been worked-out as well as the

key role of power electronics in using

renewable energies e.g. in feeding wind

and photovoltaic solar power to the

electricity grid.

ECPE has delivered significant contributions

to promote these topics and especially to

put power electronics in the context of

these megatopics.

These megatopics are still valid. But

today, the global challenges in energy

supply e.g. the finite nature of fossil fuel

resources, CO2 emissions and climate

3.3 MEGATOPIC: ELECTRONIC POWER GRIDS


change, the declining acceptance of

nuclear power, the increasing share of

fluctuating renewable energy sources and

the more decentralised power generation

are considered and discussed in a more

generic context under the headlines

Smart Grid and energy transition (e.g. the

German Energiewende).

The share and the importance of power

electronics in future electricity grids

will significantly increase whereat the

following grid functions have to be

realised by power electronics in a very

efficient way with a minimum of power

losses:

feeding photovoltaic power to the

grid (decentralised generation and PV

power plants)

feeding wind power to the grid

integration of energy storage into the

grid

bidirectional vehicle-to-grid interface

with charging EVs and providing grid

services

low-loss, long distance power

transmission using a meshed HVDC

grid

integration of off-shore wind parks

into the grid

providing local MV and LV DC grids for

improved energy efficiency

improving power quality

stabilising the new grid (U, f) with

decreasing share of rotating generators

With the Megatopic 2020 Electronic

Power Grids for efficient and

sustainable power generation,

distribution and consumption we highlight

power electronics as a substantial and

integral part of the solution of these

energy and grid related challenges.

The Electronic Grid incorporates the integration of renewable energies, loss-loss transmission, energy storage

and EV charging into the grid as well as the demand-side management with smart metering and appliances.

The Electronic Grid incorporates the integration of rene able energies loss loss transmission energ storage

19

The Joint Research Programme is

organised within the ECPE GmbH where

the Member companies who decided

to join the ECPE Research Partner

Agreement as Principal or Associate

Partner are driving R&D projects as

contract research with the Competence

Centres.

This Joint Research Programme is 100%

industry-financed and about 10-15

projects are started every year by the

ECPE Principal Partners. The research

topics are proposed by the companies or,

alternatively, are arising from an annual

call-for-proposals published among the

ECPE Competence Centres.

One exemplary highlight from ECPE

Research: Ultra-low inductance package

for SiC

This ECPE Project realised at Fraunhofer

IZM aims at the development of

an advanced power package with

extremely low DC-link inductance. The

1st demonstrator is a half bridge with

two paralleled SiC-JFETs applying printed

circuit board (PCB) manufacturing

technology combined with a Direct

Copper Bond (DCB) substrate. The SiC

chips are embedded in the PCB material

and the DC-link capacitors are soldered

directly onto the module. The simulation

for this new package shows a DC-link

inductance of 0.8 nH which is a world

record value. The measurements show

a perfect switching waveform with very

low amplitude ringing at 240MHz.

velopment methods are fundamental to

alpitronic’s ability of innovation.

Common Goals

alpitronic is eager to face the complex

challenge of developing innovative con-

cepts together with their customers,

from the first idea to the timely imple-

mentation - with competence and con-

sistency.

alpitronic’s design experts offer support

for conceptual design and dimensioning

of complex power electronic systems,

design of microprocessor architectures

of safety-related applications (ASIL / IEC

61508), circuit simulation, power loss and

tolerance calculations, thermal and coo-

ling system design, as well as optimizati-

on of costs and power losses on existing

circuits.

In the field of system engineering, espe-

cially for automotive power electronics,

alpitronic develops and tests inverters for

traction and range extender applications,

including special solutions like high swit-

ching frequency inverters with alpitronic‘s

ARCP technology. alpitronic’s motor test

bench provides the facilities to do inver-

ter and e-machine testing, including high

precision power loss determination of

components and the whole system.

alpitronic provides also development and

manufacturing support: schematic and

layout design, production and commissi-

oning of prototypes, handling of the cer-

tification process, handling of small series

production.

Pioneering Technology

alpitronic‘s new resonant switching ARCP

technology for half-bridges allows high

frequency switching of 50kHz and mo-

re at currents of several hundred am-

peres. The technology was first realized

in a 100 kW inverter prototype (400V DC

link voltage and phase current 250Aeff).

A 550Aeff device is currently in develop-

ment. Switching frequencies of 50 kHz

and more enable new applications like

high-revving, or high pole count, compact

motors. The technology provides weight

and volume reduction of currently availa-

ble inverters by 30% through reduced

cooling demand and small EMC filter.

products such as excitation systems for

generators, static starter devices for gas

turbines, variable speed drives for aux-

iliaries in boiler feed water pumps or in

cooling tower fans.

Renewable Power:

It offers the most comprehensive range

of renewable power generation solutions

today: hydro power, wind power, geo-

thermal, biomass and solar. All renewa-

bles need converters to be connected to

the grid: variable speed converters for

hydro-pump or full scale converters for

offshore wind turbines.

Alstom Grid: Energising a smarter grid

This sector provides integrated and custom-

ised turnkey solutions such as alternating or

direct current substations, from medium up

to ultra-high voltages. These solutions en-

able the efficient transmission of electric-

ity and support the development of Smart

Grids and Supergrids.

Power electronics is a revolution for the

transport of electricity due to point to

point or meshed HVDC (high voltage

direct current).

AMANTYS LTD

Amantys is headquartered in Cambridge,

UK where a multi-disciplined team of

engineers develop innovative products

and solutions for intelligent power

electronic switching.

Our product portfolio includes IGBT Gate

Drivers for IGBT Modules at operating vol-

tages from 1200V to 6500V, and in vari-

ous package types including High Power

Modules (HPM) and PrimePACKTM (*), also

known as High Power Dual Package.

Amantys Power Drives integrate a unique

monitoring and data logging capability to

measure, encode and communicate cri-

tical performance parameters externally.

Data is delivered from the heart of the

power switch to a host control system

or over a web server to a remote control

centre, thus allowing faults to be moni-

tored and diagnosed, and reducing the

need for field intervention.

Known as Amantys Power InsightTM, this

sub-system comprises the hardware and

full software protocol to deliver switching

characteristics and fault codes from the

IGBT Module. The hardware includes an

ARM microcomputer, programmable de-

vice and sensing circuitry.

An Amantys Power Insight Adapter is of-

fered to assist during develpoment and

commissioning of new equipment, obser-

ving performance and enhancing system

availability. With this technology, the de-

signer can program thresholds and alarms

to set how data is logged on the Gate

Drive or communicated externally. In ope-

ration, Insight can deliver fault codes and

performance metrics in real-time.

Our IGBT Drivers deliver enhanced re-

liability and performance for medium

and high voltage switching applications

such as HVDC (High Voltage DC) Voltage

Source Converters, locomotive traction,

both for suburban and high-speed trains,

medium voltage motor drives, and rene-

wable energy generation, including wind

turbine inverters and solar farms.

Our Gate Drives can be configured re-

motely over the Insight interface to drive

IGBT Modules from all major manufac-

turers; the same programmability can be

used to tune switching characteristics ex-

ternally without the need for dismantling

the power assembly.

The company has announced a series of

partnerships with IGBT manufacturers,

and in addition, has developed a number

of gates drivers and similar products for

custom applications.

ANVIL SEMICONDUCTORS LIMITED

Anvil Semiconductors Ltd was establis-

hed in August 2010 as a spin-out of the

University of Warwick to exploit its pa-

tented developments in Silicon Carbide

(SiC) power semiconductor technology.

With these ideas in place SiC will displace

silicon in the device market range of

$1billion to $5 billion per annum mainly

in electric vehicle, photovoltaic and inver-

ter applications. Anvil was founded by

Prof. Phil Mawby and Dr. Peter Ward who

are global experts in the fields of power

devices; their modelling and manufacture.

Anvil’s mission is to develop these ideas

to become the leading source of IP

to the World’s Silicon Carbide Power

Semiconductor Industry and from there

become a mass producer of low-cost me-

dium-voltage SiC devices.

Advantages of Silicon Carbide

SiC offers many superior properties over

silicon:

SiC can sustain higher voltages redu-

cing system complexity and cost whilst

improving system reliability.

SiC can carry higher currents with lo-

wer parasitic capacitances.

SiC has a higher thermal conductivity

and can operate at temperatures up to

400 °C (cf silicon 150 °C) reducing the

cooling costs and complexity of appli-

cations such as hybrid vehicles.

Birmingham Road, Allesley,

Coventry, CV5 9QE, United Kingdom

Phone: +44 1832 29 36 19 [email protected]

www.anvil-semi.co.uk

SiC is able to switch ten times faster

allowing the use of smaller capacitors

and inductors producing cheaper,

smaller and more efficient systems.

It is clear that SiC power devices repre-

sent a disruptive technology which will

enable functionalities and efficiencies not

reachable with silicon.

Anvil’s Solutions to previous limita-

tions of Silicon Carbide

Anvil Semiconductors understands the

factors which has prevented SiC transis-

tors being improved and has developed

solutions to allow its exploitation:

A unique SiC processing furnace will

allow the demonstration of Anvil’s

unique oxidation and annealing pro-

cess solutions; allowing high quality

transistor manufacture.

Processing techniques to prevent the

distortion that normally occurs when

growing 3C-SiC on silicon. These will

open up the commercial use of 3C-SiC,

and provide cost effective solutions.

Anvil also believes that 3C-SiC suffers

much less of the processing problems

noted for 4H-Si.

A novel Insulated Gate Bipolar

Transistor (IGBT) that allows its fabrica-

tion in SiC and also does not suffer the

slowness of turnoff in comparison with

MOSFETs seen in silicon designs.

In summary, Anvil addresses the factors

needed to achieve high-quality SiC swit-

ches and diodes, and reduce their unit

costs (substrate, processing and yields).

Robert Bosch GmbH

The Bosch Group is a leading global sup-

plier of technology and services. In fis-

cal 2012, its roughly 306,000 associa-

tes generated sales of 52.5 billion euros.

Since the beginning of 2013, its opera-

tions have been divided into four busi-

ness sectors: Automotive Technology,

Industrial Technology, Consumer Goods,

and Energy and Building Technology. The

Bosch Group comprises Robert Bosch

GmbH and its roughly 360 subsidiari-

es and regional companies in some 50

countries. If its sales and service partners

are included, then Bosch is represented

in roughly 150 countries. This worldwi-

de development, manufacturing, and sa-

les network is the foundation for further

growth. Bosch spent some 4.8 billion

euros for research and development in

2012, and applied for nearly 4,800 pa-

tents worldwide. The Bosch Group’s pro-

ducts and services are designed to fas-

cinate, and to improve the quality of life

by providing solutions which are both

innovative and beneficial. In this way, the

company offers technology worldwide

that is “Invented for life.”

Power electronics: from technologies

to product innovations

Power electronics is a key enabling tech-

nology in many areas in which Bosch

does business, including automotive

technology and e-mobility (fig. 1), indus-

trial drives, power tools, and renewable

energy (fig. 2).

Cars in particular pose special challenges

such as space and weight requirements,

robustness under extreme mechanical and

climatic conditions, and how to achie-

ve volume production at low cost. Power

electronic Inverters, for instance, control

the energy flow for electric driving in hyb-

rid and electrical vehicles. More precisely,

they convert direct current from the trac-

tion battery into the three-phase alterna-

ting current that powers the electric motor.

Inverters also control energy recuperation,

which saves on fuel, as well as the currents

recharging the battery. The second genera-

tion of Bosch inverter systems has already

entered series production (fig. 3 - 4).

Miniaturization of power electronics plays a

central role in product innovation: reducing

space requirements, decreasing weight,

improving efficiency, and ultimately lowe-

ring the cost of power electronics will make

fuel-saving hybrid technology affordable

to more and more drivers. In interdiscipli-

nary teams of engineers, Bosch is develo-

ping miniaturization and next-generation

power-electronics system integration on

all technology levels, from semiconductor-

components, power-modules and control

units to overall electric drive systems.

Boschman Technologies is the worlds lea-

ding supplier of automatic molding sys-

tems using Film Assisted Molding (FAM)

technology.

The experience built up with the molding

technology Boschman Technologies also

uses for the Silver Sintering Processes of

power packages to replace soldering.

Boschman Technologies develops new

processes for the encapsulation of ad-

vanced packages and delivers the en-

capsulation equipment to the worldwide

semiconductor and electronic indust-

ry. Boschman Technologies provides in a

close cooperation with the semi-indust-

ry new processes and equipment for the

Power packages. The “basic “ technology

of molding with film started more than

15 years ago and the semiconductor in-

dustry looks with favour on the advanced

processes of encapsulation.

Boschman Technologies has the tech-

nology to (partly) encapsulate the Power

packages in such a way that the “heat-

sink” area of the package can perform its

function in a perfect encapsulated envi-

ronment.

With single or double films lining of the

molded parts, film assisted transfer mol-

ding technology (FAM) provides easy re-

lease of the compound from the mold

and keeps certain specific surfaces clear

from molding compound.

Transfer molding is the primary process

method for the microelectronic encap-

sulation and with encapsulation materi-

al-epoxy molding compound (EMC), one

of the first applications was the transis-

tor package. Traditional transfer molding

process has disadvantages including

EMC bleed and resin flash, time consu-

ming mold cleaning, mold wearing, pa-

ckage deformation during the ejection

process and lead frame deformation or

(ceramic) substrate cracking due to clam-

ping. FAM deals with challenges of re-

leasing components from the mold and

keeping certain surfaces -heatsink- clean

from molding compound.

Releasing from the mold and product

surfaces is accomplished by a “seal film”

and the seal film is refreshed after every

molding cycle. The seal film is functio-

ning as a gasket, reducing the clamping

force, and allowing clamp and seal on

dies and ceramic surfaces.

The technology developed for the mol-

ding presses Boschman Technologies is

using for the Sintering Systems.

Sintering in the Boschman presses is for

lead frames, substrates or ceramic carri-

ers and the film protect the die surfaces

against damages. With the dynamic in-

sert technology the clamping is done

with a very precise force control compen-

sating for built up tolerances.

The Boschman Systems are designed for

low cost, fast and easy product conversion.

ported. This is for around 50 countries

including USA, Canada, Brazil, Argentina,

Africa and China.

The People

In 1992 he became the managing direc-

tor and in January 1995 he became the

CEO of the company. Mr. Juricek has a

clear idea on the core principles behind

the Brano brand, “Our core principles are

represented by five stones. These are; po-

licy, effectiveness of internal and outside

sources, development of partnerships,

continual improvement and the orienta-

tion and opening of new market places.”

But this is not just a statement on a web-

site, he also outlines how they achieve

this, “We have a clear strategy involving

implementation through internal metho-

dologies, processes and procedures.”

Brano not only provide training for their

employees but are also working on im-

proving their lives, “Employees are a very

important resource for us. We work on a

number of social projects for them. We

have recently established a kindergarten

at the company and we are building a

new training centre in 2012. This will not

just be for our technical works but for

everyone in our company who wants to

gain knowledge and skills.”

The Future

These employees are crucial to further

development, “We are continually loo-

king to produce new products. For ex-

ample we are developing an environ-

mentally friendly battery for stop/start

mechanisms. We are also working on

a new development project out of our

standard automotive business. We would

like to introduce new kind of wheel

chair for disabled people,” confirms Mr.

Juricek. On designs of new products are

working more than 150 design technici-

ans and product designers.

The company is also keen to stress its ad-

herence to standards, “We do all the im-

portant dynamic and durability tests for

car makers,” states Mr. Juricek. He also

emphasises the company’s environmen-

tal credentials, “We are a clean company,

we have all the certifications and we are

proud of this. It is part of the philosophy

of our people and our company culture.”

We at Daimler AG as the inventor of the

car and the truck assume responsibility

for their future. Our Road to Emission-free

Driving stands for our commitment to se-

curing sustainable mobility. Our aim is to

markedly reduce fuel consumption and

emissions already today and to eliminate

them entirely in the long term. To this

end, we are developing a broad spectrum

of state-of-the-art drive technologies that

meet the specific requirements placed

on today’s and tomorrow’s mobility in all

modes of road transportation.

The key to greater efficiency and environ-

mental compatibility lies in the electrifi-

cation of the drivetrain. This offers great

potential for improvement, which is be-

ing realized for example in auxiliary units,

the automatic start / stop system, and

hybridization. For this stage of Daimler’s

“road map”, we have developed a modu-

lar hybrid system that offers various pos-

sibilities for extension in terms of perfor-

mance and range of vehicle applications.

All hybrid drive variants can be realized

on this basis: from so-called mild hybrids,

with electric recuperation and boost

function, up to purely electric driving.

The future of the modular hybrid system

is shown by the Mercedes-Benz Vision

500 Plug-in HYBRID. With a certified

consumption of only 3.2 liters of gasoline

per 100 kilometers and a purely electric

operating range of 30 kilometers due to

a battery which can be recharged, it of-

fers green technology in a fascinating

luxury-category vehicle.

The future has begun: Daimler vehicles

with battery and fuel cell have proven

their technical feasibility and are ready

for every day use: The smart fortwo

electric drive, Mercedes-Benz A-Class

E-CELL, Mercedes-Benz B-Class F-CELL,

Mercedes-Benz Vito E-CELL, Fuso Canter

E-CELL, and Mercedes-Benz Citaro

FuelCELL Hybrid are already in operation

today and offer electromobility in all areas.

But there are still a number of challeng-

es that will prevent electric automobiles

from being a familiar sight on the roads

in the near future. Boosting operating

range and performance, cutting systems

costs, and establishing an infrastructure

are the requirements that yet remain to

be fulfilled. Power electronics is a key to

master these challenges.

In R&D we investigate and optimize all

the key components for electromobil-

ity, including batteries, charging systems,

electric motors, drive inverters, and auxil-

iary devices together with the HV power

net architecture in the car.

Current rail inverters are mainly designed

for a high voltage of 1500V from overhead

wires and therefore downsizing of high vol-

tage power modules is important. Hitachi

has developed a compact 3.3kV/1200A hy-

brid module for rail car inverters having a

high voltage resistance of 3.3kV using SiC.

The hybrid module developed combines

3.3kV SiC-SBDs (Schottky barrier diode) and

Si-IGBTs. To achieve a compact size mo-

dule, Hitachi optimized both the SiC-SBD

structure and the Si-IGBT device characte-

ristics taking full advantage of device, cir-

cuit and loss simulations, and succeeded in

reducing the module size to approximately

two-thirds that of current Si modules.

In 2009, Hitachi developed 3kV-class SiC-

SBDs which employ a JBS (Junction Barrier

Schottky) structure that combines Schottky

junctions with pn junctions, and mounted

these in a power module, which led to the

development of this compact SiC hybrid

module for railcar inverters. Features of the

technology developed are as below:

SiC-SBD

To achieve a compact power module, it is

necessary to pass a large current across the

SiC-SBD which has a limited surface area.

By employing the JBS structure which com-

bines Schottky junctions and p-n junctions,

both conduction loss and leakage current

can be reduced. This effect was further en-

hanced by applying device simulation to

optimize the JBS structure successfully re-

sulting in increased current per SiC-SBD sur-

face unit area. Further, as the internal elec-

tric field of SiC is approximately 10 times

that of Si, the optimal device edge struc-

ture was designed using device simulation

to decrease the electric field around the de-

vice edge and assure the reliability required

for rail cars.

Si-IGBT

Si-IGBT device with trench gate structure

was developed, whose cell size was one

third of previous generation device, leading

to 20% loss reduction. The device charac-

teristics were optimized by applying circuit

and loss simulation in rail application cir-

cuits.

The compact 3.3kV/1200A hybrid modu-

le with the size two-thirds that of conven-

tional Si module and maximum operating

temperature of 150°C, was fabricated com-

bining the Si-IGBT and the SiC-SBD tech-

nologies.

Hitachi also developed SiC hybrid inverter

for rail cars that is compatible with 1,500V

DC overhead power supply using the com-

pact hybrid module and lightweight oil-free

capacitors. Size and weight of 40% smaller

and lighter than current mainstream inver-

ters, and 35% reduced power loss are suc-

cessfully achieved.

Our products

Enable energy-efficient designs and

Deliver the innovations needed for a

sustainable society.

Our manufacturing processes

Set the industry benchmark for resour-

ce efficiency.

Drive the transition towards more sus-

tainable manufacturing practices.

Reveal impressive efficiency gains for

electricity consumption:

savings achieved would power a city

with more than 1.5 million inhabitants

for a whole year.

Enabled us to meet the reduction tar-

gets for Kyoto gases (such as PFCs)

three years ahead of the voluntary in-

dustry agreement.

More power – sourced through effici-

ency:

We all need energy – it heats our houses,

powers our cars and lights our cities. The

reality is, however, that limited fossil fu-

el reserves will not be able to meet the

world’s growing requirements. The con-

sequences of climate change are also for-

cing us to explore sources of energy with

lower carbon footprints. Electricity will

remain our main source of power throug-

hout this century. And a lot of that po-

wer will be sourced through advances in

efficiency. Our innovative semiconductor

technologies are helping to create much

needed efficiency gains across industri-

al plants, server farms, domestic applian-

ces, HVAC (Heating, Ventilating and Air

Conditioning) facilities and lighting sys-

tems. Powerful chips, for instance adjust

the speed of industrial drives and pumps

in step with actual demand, thus drama-

tically increasing motor efficiency. But

that’s not all. They also enable regenera-

tive braking. This involves capturing the

energy released when heavy-duty drive

systems slow down and feeding it back

into the grid.

Smart chips across the entire energy

chain:

Our semiconductor technologies are de-

signed to optimize all steps in the energy

chain – from generation through trans-

mission to the actual point of use. Their

value extends far beyond efficiency gains.

Wind and solar power can only be fed in-

to the grid with the help of semiconduc-

tors, for instance. High-voltage direct-

current transmission systems distribute

electrical power over long distances with

a minimum of losses. And our innova-

tive chip solutions are helping to build

tomorrow’s smart grids, where supply

and demand are dynamically linkend.

Digital IGBT Drivers combine intelli-

gent switching with full protection

Digitally controlled IGBT gate drivers in-

crease reliability and reduce switch-ON

losses by changing the operation charac-

teristics through software.

IGBT-modules are frequently used in

Transportation, Industrial Drives and

in the field of Renewable Energies.

Reliability and efficiency are crucial in

these high power applications.

InPower Systems has introduced to the

market a series of digital gate drivers for

high-power IGBT modules with blocking

voltages from 1200V to 6500V which

comply with these requirements.

Our technology allows decreasing the

switch-ON losses by using different gate

resistors during turn-ON. Multiple soft

shut down is realized by using various

gate resistors during turn-OFF. These

controlled switching characteristics

reduce overshoot and the need for

snubber.

Excellent protection of the IGBT and the

free wheeling diode is provided using di-

gital multi-level desaturation control and

di/dt control, active feedback clamping

and multiple soft shut down. All pro-

tection features are supervised by the

software and guarantee an outstanding

protection of the IGBT and diode. Rapid

short circuit recognition and limitation in

all short circuit conditions, over-voltage

during short circuit turn-OFF as well as

tuning capabilities according to the cus-

tomer application are promising features

for power electronics system solutions.

The drivers may be used both in dual-

and multilevel topologies as well as for

parallel connection of IGBT.

Customers are not required to have eit-

her programming skills or additional

equipment as the IPS drivers are supplied

plug-and-play i.e. modified and opti-

mized for the IGBT module used.

Our drivers are used in high pow-

er applications as Renewable Energies

(Windmills, Solar Inverters), Traction

The Company

Johann Lasslop GmbH is a medium-scale

company, which stands for 50 years

of quality, flexibility and innovation.

As an international company J-Lasslop

has established itself as a specialist in

the development of quality inductive

components. The special strength is for

customer-specific solutions, according

to requirements: quick, flexible and

reliable – from individual items to series

production.

An efficient production of innovative in-

ductive components is only possible with

many years of experience, competence

and creativity, which are all combined

to the state-of-the-art. Here, the self-

imposed requirements on the compo-

nents „smaller-lighter-lower losses“ are

always the target of development work.

These components have been widely im-

plemented in the recent years, especially

when very little space is available and the

heat rice plays a critical role.

With individually tailored advice we offer

support from the early stage of develop-

ment to find new solutions and advance

your products. The effect is an optimal

part relative to efficiency and design size.

Through continuous research and devel-

opment, the own construction of tools

At the heart of … renewable energy

LEM transducers, specifically designed for

renewable power systems, control the

energy flow and waveform of power sent

to the grid from photovoltaic and other

renewable energy systems. They measure

the current to help optimally position the

turbine to the wind and to use the pho-

tovoltaic panels to their maximum effici-

ency in a safe manner.

At the heart of … uninterruptible

power

Imagine a world where power can fail.

A world in which data centres lose their

data, hospital equipment stops working

and systems come to standstill. Wherever

continuous, uninterruptible power is cri-

tical, LEM’s Sentinel Battery Monitoring

System can monitor the condition of

standby batteries to ensure that they are

always ready to supply emergency back-

up power.

LEM ... at the heart of the future

Intelligent power management is critical

for conserving energy. As the world’s lea-

ding manufacturer of transducers, LEM is

helping the world to move towards a gre-

ener, more energy-efficient future with

products such as the Wi-LEM Wireless

Local Energy Meter. By showing users ex-

actly how much power is being used, Wi-

LEM helps them to protect the future by

reducing their power consumption.

Transducers are the hidden heart of

power electronics

You use LEM transducers every day. They

are present in trains, buses, lifts, cars and

they help to protect vital equipment in

hospitals, airports and data centres. They

are in industrial motors, electric vehicles,

solar panels and wind turbines as well as

in battery-backed uninterruptible pow-

er supplies (UPS) that provide continuous

power to computer servers.

LEM transducers help to make your world

safer and more energy efficient. They

provide the feedback signal which helps

to control the motors which drive a vast

number of machines, measuring com-

plex currents and voltages from as little as

0.1 A in drills, to 20000 A in electrolysis

equipment and up to 10000 V in the trac-

tion control for trains.

With higher accuracy and speed, the feed-

back signal from LEM transducers enables

smoother control and operation. They al-

so help to reduce energy consumption by

30% or more through the intelligent con-

trol of variable speed drives.

At the heart of … industry

LEM transducers help to make your world

a smoother place. In lifts, for example,

they help to prevent the doors closing on

passengers. They keep the cabin stable

when people enter and ensure that the

lift rises and falls smoothly by adjusting

the torque of the motor. Their signals are

also used to stop the lift at exactly the

right level.

At the heart of … transport

Trains propulsion is provided by electric

motors driven by inverters. These inver-

ters rely on LEM transducers to measu-

re, optimise and adjust the power that is

sent to the motors, improving both per-

formance and reliability. In electric and

hybrid cars, LEM transducers monitor

energy levels to and from the battery as

well as saving energy by controlling elec-

tric power steering.

History of MERCE-France

The industrial research laboratory was

established in Rennes in November

1995 under the name of Mitsubishi

Electric Information Technology Europe

- Telecommunication Laboratory. Its initi-

al mission was to design future commu-

nication systems, fixed or mobile, wired

or wireless. With the expansion of the

European R&D Centre towards energy

and environment, it diversified its scope

of work in 2008 by creating a new de-

partment focusing on sustainable energy

systems with a primary focus on power

electronic systems, and is now referred as

Mitsubishi Electric R&D Centre Europe -

France (MERCE-France).

Main R&D topics and activities

As an industrial laboratory, we combine

long- term research with practical appli-

cations in standards and industrial pro-

ducts. Therefore, the activities cover the

whole chain of R&D from theoretical stu-

dies and simulations to the development

of demonstrators and prototypes in rele-

vant domains.

For energy and environment technology,

we are working on power electronic sys-

tems. Main R&D topics are High Density

Power Converters including reliability,

energy management systems and motor

drives. Power Electronics developments

play a key role in energy and environ-

ment technology.

For telecommunications technology, we

are working on high reliability communi-

cations for railway and train control, sa-

tellite communications, car communica-

tions and access network security.

In parallel to the internal research activi-

ties, we are actively contributing to stan-

dardization bodies both at European level

(ETSI) and at International level (3GPP,

ITU-T, FSAN, IEEE, DVB, UIC…).

We put a lot of efforts into joint research

and development programs with other

actors in the framework of French or

European projects.

Moreover, direct collaborations with aca-

demic research teams (labs, universities,

engineering schools…) all over Europe

are regularly established.

Composed of more than 40 people, in-

cluding PhD students, MERCE-France is

a dynamic R&D laboratory developing

advanced technology solutions with a

strong commitment to innovative and

business-driven research. The laboratory

brings, besides the support and experi-

ence of a big industrial group, the dyna-

mism and creativity of a motivated team

that benefit from the melting of both

European and Japanese cultures.

RO-LINX® busbars

Design and manufacturing of laminated

busbars which meet the most stringent

requirements for rail traction converters,

grid, wind and solar converters and dri-

ves for industrial applications. RO-LINX®

busbars feature low inductance, cont-

rolled partial discharge, high current ca-

pabilities and compactness. As the global

leader in the world of laminated busbars,

RO-LINX®‘s main differentiators are superb

quality and reliability, electrical and me-

chanical expertise, co-engineering and

flexible lead times.

curamik® ceramic substrates

curamik® ceramic substrates consist of

pure copper bonded to a ceramic subst-

rate such as Al2O3, Zr doted Al2O3 , AlN or

silicon based Si3N4.

curamik provides two technologies to at-

tach the substrate with the copper. DBC

(direct bond copper) – a high tempera-

ture melting and diffusion process whe-

re the pure copper is bonded onto the

ceramic and AMB (active metal brazing)

– a high temperature process where the

pure copper is brazed onto the ceramic

substrate.

The high heat conductivity of the cera-

mic as well as the high heat capacity and

thermal spreading of the thick copper

cladding makes our substrates indispen-

sable to power electronics.

curamik® micro-channel coolers

curamik® micro-channel coolers consist

of several layers of pure copper with very

fine structures. These layers create three-

dimensional structures for cooling high-

performance electronics. The design of

the different layers can be adjusted to

customer-specific requirements.

Our coolers are currently used for Laser

Diode cooling, but also for the cooling

of high-performance components, high

brightness LED or solar-cell arrays.

ROHM Semiconductor –

Quality at all times

ROHM is a leading global semiconduc-

tor and electronic components manufac-

turer based in Kyoto/Japan. Among mul-

tiple products, the company’s portfolio

consists of state-of-the-art power man-

agement and eco devices. Its SiC diodes,

MOSFETs and modules can be widely

deployed in automotive, industrial, and

energy harvesting applications. SiCrystal

AG, a German based company part of the

ROHM group since 2009, has adopted an

integrated wafer production system from

raw SiC material to crystal growth, wafer

processing and inspection. Today, ROHM

is able to offer the world’s first full-scale,

mass production of next-generation SiC

components providing high reliability and

advanced characteristics.

SiC Schottky Barrier Diodes

Ultra-small reverse recovery time – impos-

sible to achieve with silicon FRDs – allows

for high-speed switching. This minimizes

reverse recovery charge (Qrr) reducing

switching loss considerably and contrib-

utes to end-product miniaturization. In ad-

dition, ROHM provides significantly lower

VF, which makes them an optimum

replacement for rectification diodes.

The Industry’s First Mass-Produced

SiC Power MOSFETs

SiC MOSFETs have much lower switching

loss than Si-IGBTs, which enables higher

switching frequency, smaller passives,

smaller and less expensive cooling system.

The guaranteed operating temperature is

currently up to 175 °C due mainly to ther-

mal reliability of packages. When proper-

ly packaged, they can operate at 200 °C

and higher.

High Voltage isolated SiC Gate

Drivers

Due to ROHM’s proprietary microfabri-

cation expertise, the new BM6 family of

2,500 Vrms isolated SiC gate drivers facil-

itates low-power consumption and small

designs. Ideal for the control of invert-

ers and DC/DC converters, they can drive

both, IGBTs and SiC MOSFETs. Featuring

compactness and multiple protection

functions, they guarantee a stable, high

speed operation even in high power re-

gions.

The Industry’s First Mass-Produced

“Full SiC” Power Modules

ROHM has pioneered commercial power

modules equipped with SiC-MOSFETs

and SiC-SBDs. SiC modules allow sub-

stantial reduction in switching losses as-

sociated with Si-IGBT’s tail current and

Si-FRD’s recovery current.

SiC power modules are increasingly ap-

plied to power supplies for industrial

equipments, PV power conditioners and

high current motor controls.

Power Resistors

Energy efficiency and reliability

The Schaffner Group was found-

ed in 1962 through the vision of Hans

Schaffner how to measure and eliminate

problems of electromagnetic interference

in electronic devices. Today the Schaffner

Group is the international leader in the

development and production of solutions

which ensure the efficient and reliable

operation of electronic systems.

We do not want to stop here. We aim to

move forward in contributing towards a

future that will be more energy efficient,

use more renewable energy, and that

will offer sustainable transportation op-

tions such as more trains and hybrid or

electric cars. All these objectives require

more power electronics than today, and

power electronics require solutions from

Schaffner.

The Group‘s broad range of products and

services includes EMC/EMI components,

harmonic filters and magnetic compo-

nents as well as the development and

implementation of customized solutions.

Schaffner components are deployed in

energy-efficient drive systems and elec-

tronic motor controls, in wind power and

photovoltaic systems, rail technology, ma-

chine tools and robotics as well as power

supplies for numerous electronic devices

in sectors such as medical technology or

telecommunications.

Schaffner provides on-site service to cus-

tomers around the world through an

efficient, global organization and makes

ongoing investments in research, deve-

lopment, production and sales to syste-

matically expand its position as leader on

the international market.

Innovation success factors

Schaffner‘s Group Innovation Center is

located next to the company‘s headquar-

ter in Luterbach, Switzerland. This assures

a seamless collaboration with the decision

makers of the product divisions.

We are convinced, that efficient and fo-

cussed networking is one of the most im-

portant innovation success factors. This is

why Schaffner is very open for R&D con-

tacts with industry as well as with univer-

sities and research institutes.

Schaffner‘s research is focussed on the mi-

tigation of distortions, generated by mo-

dern power electronic systems. This requi-

res a deep understanding of the distortion

sources and of adequate suppression con-

cepts for the different types of distortions.

Novel magnetic materials as well as design

tools for magnetic components and elec-

tronic power quality mitigation functions

get our best attention, in order to perma-

nently improve our capabilities to serve

the very different requirements of our cus-

tomers.

In 2011 Semikron introduced a revolu-

tionary packaging technology for power

semiconductors which does away with

bond wires, solders and thermal paste.

The new SKiN Technology is based on

the use of a flexible foil and sintered

connections rather than bond wires,

solders and thermal paste. This results in

a higher current carrying capacity and 10

times the load cycle capability – unthink-

able with the restrictive wire bonding

used in power electronics in the past.

Therefore converter volume can be

reduced by 35%. This reliable and space-

saving technology is the optimum

solution for vehicle and wind power

applications.

Power electronics drive many of

todays and future products and

systems

Siemens is positioned at the leading edge

of technology and is with 80 billion re-

venues and around 400.000 employees

one of the largest electric and electronic

companies worldwide. Power electronics

play an important role in all four sectors

- many products include such devices in

all voltage and power levels. Siemens has

intensive research programs in the field

of power electronic components itself

but especially in the field of their applica-

tion in products and systems. Internal re-

search as well as close research coopera-

tion with universities is the base for new

technologies as part of new products

and systems for demanding markets and

applications.

Improving public healthcare

Power electronics are an essential part

of many medical equipment and systems

of the sector Healthcare. For example by

high speed dynamic controlling of the

currents for generating high strength ma-

gnetic fields inside magnetic resonance

imaging scanners (MRI).

More, more efficient and more

sustainable energy

For many years power electronics are

used in high power and high voltage

energy equipment - for instance thyris-

tors and IGBTs for high voltage DC trans-

mission (HVDC). The transformation of

todays grid to handle an ever increasing

amount of fluctuating renewable decen-

tral energy generation requires an effici-

ent transmission of electrical energy lo-

cally as well as over wide distances. All

options and techniques to solve this have

as a common base the need for power

electronics to provide the necessary con-

trol of electrical energy transmission.

Modern cities and infrastructure

Reliability, safety, security and flexibi-

lity play an important role in medium

and low voltage power distribution, in

urban railway infrastructure as well as

with innovative smart grid technologies.

Urbanisation stands for a rapid growth

of cities to mega cities and this drives the

need for power electronic equipment to

distribute and control electrical energy

flows in a highly densified urban environ-

ment.

Automation and drives technology

Automation and drive products were the

main application of power electronics for

many decades. More or less every facto-

ry and plant use such equipment. New

applications with very dynamic growth

emerge with small and big scale regene-

rative power generation such as photo

voltaic and wind tubrbines and the elec-

trical passenger car.

Wärtsilä is a global leader in complete life-

cycle power solutions for the marine and

energy markets. By emphasising techno-

logical innovation and total efficiency,

Wärtsilä maximises the environmental and

economic performance of the vessels and

power plants of its customers. In 2011,

Wärtsilä‘s net sales totalled EUR 4.2 billion

with 18,000 employees. The company has

operations in nearly 170 locations in 70

countries around the world.

Marine Solutions

Wärtsilä is the marine industry’s systems

integrator and leading global provider of

ship machinery, propulsion and mano-

euvring solutions, including electrical and

automation packages, propulsors and

all related services. This complete port-

folio, together with our in-house experi-

ence and expertise, enables us to interface

at all stages, from first concept onwards,

throughout the entire lifecycle of vessels

and offshore applications.

In Norway, Wärtsilä designs, engineers

and produces electrical and automation

products and solutions for marine vessels,

offshore FPSO (floating production, sto-

rage and offloading) and drilling units.

Low Loss Concept offers improved

performance at lower cost

The LLC is an effective way of avoiding the

use of heavy and space-consuming trans-

formers in the power distribution systems

for electric propulsion solutions on ships.

Wärtsilä’s LLC solution is based on a trans-

former in which the main windings are

shifted by 30 degrees to cancel the 5th

and 7th harmonic currents introduced in-

to the network by rectifying bridges. The

bridges are supplied from the two phase-

shifted sides of the LLC transformer. This

configuration means that system efficien-

cy is 1-2 per cent higher than in traditio-

nal transformer-based systems, resulting

in better fuel economy and reducing the

need for auxiliary systems.

With LLC, a vessel’s propulsion system

can be divided into several units that

work independently. In the case of a

short circuit, power generation can be re-

duced, but all the ship’s propellers conti-

nue to function.

Unique Frequency Converters or

Variable Speed Drive

The water- cooled variable speed drive

is the world’s most compact low volta-

ge (690 V) maritime variable speed drive.

The depicted 1.5 MW converter has a

width of just 900 mm and a depth of

1000 mm. The redundant design and

slide-in interchangeable power modules

make service easy and efficient. The va-

riable speed drive is offered in paralleled

configurations up to 5.5 MW with active

and passive rectification.

Multidrive with Electronic DC

Breaker for fast fault handling

Combined with built-in patented electro-

nic DC breakers, of which one is depic-

ted, the inverters in a multi-drive soluti-

on work independently. In the case of an

inverter module failure, the DC breaker

can cut off the faulty module within a

few microseconds, giving the common

DC link of about 1 kV voltage no chance

to collapse.

Low Loss Concept (LLC)This patented, water-cooled, IGBT-based electronic

DC-breaker is capable of disconnecting 1.5 MW

inverter modules within a few microseconds from a

common 1 kV DC-link

The Institute for Power Electronics and

Electrical Drives (ISEA) of RWTH Aachen

University has been working on Power

Electronics, Power Semiconductor

Devices, Electrical Drives and

Electrochemical Energy Storage Systems

for more than 45 years. Under the su-

pervision of institute director Prof. Dr. ir.

Dr. h. c. Rik W. De Doncker and the head

of the Electrochemical Energy Storage

Systems Group Prof. Dirk Uwe Sauer, the

focus of ISEA is on research and develop-

ment activities in close co-operation with

national and international companies, as

well as on public funded research pro-

jects. In addition, ISEA offers engineering

services.

One of the main research areas of the

institute are power electronics, drives and

batteries for electric, hybrid and conven-

tional vehicles. Researchers work on elec-

trical architectures and drive trains on the

system level and investigate, for example,

the effect of different voltage levels and

the utilization of DC/DC converters on

the overall efficiency or the integration of

the energy storage into the grid, as well

as on the component level, for example

designing highly efficient converters or

investigating the aging behavior, diag-

nostics, and energy management of bat-

tery packs. Drive inverters including sen-

sorless and highly dynamic torque control

are also a major topic. A special focus lies

on the design and realization of switched

reluctance drives, which feature a low-

cost robust design and are very suitable

for compact high-speed drives. Also the

acoustic behavior of drives is investigated

and optimized. Device level research is

conducted, too, such as specific package

design for semiconductors for automo-

tive applications.

Another main research area is sustainable

energy. Also here, power electronics and

storage systems are key technologies to

enable a largely renewable energy gen-

eration while maintaining a stable grid.

As an example, ISEA works on highly

efficient converters for solar applications

and has developed a test bench for the

characterization of commercially available

photovoltaic inverters.

Furthermore, the institute is also active

in the research fields of traction applica-

tions, home appliances and industrial

applications.

Currently, more than 70 scientists and

engineers jointly research and study at

ISEA together with more than 50 stu-

dents. The close cooperation of experts

for power electronics, drives and battery

systems enables highly optimized systems

for all the applications described above.

Overview and education:

The University of Applied Sciences

Augsburg is located in the South of

Germany and has a history of more than

300 years. In the last century intermittent it

was called “Rudolf Diesel Polytechnikum”

with respect to Augsburg’s most popular

engineer Rudolf Diesel, the inventor of

the world wide well known diesel engine.

Today, the University of Applied Sciences

Augsburg has approx. 4500 students and is

well established. The educational arm con-

sists of seven faculties. One of them is the

department of Electrical Engineering with

approx. 600 students and 18 professors.

It contains the power electronics institute

with actual 35 students per year, too.

In the power electronics course of the

Bachelor- degree following items will be

discussed:

Passive components, the influence of

the EMI behaviour and filter topologies

Today’s most important semiconductors

DC/DC converter

DC/AC and AC/DC converter

Principles of SMPS

IIn cooperation with the University of

Ulster (Belfast), a Master course will be

offered. In the “power electronics and

drives”- lecture the students learn details

of space vectors and different types of

three phase inverters. Mini projects com-

plete the course.

The new degree “Master of Applied

Research”, university experiences come

together with the industry. For details,

please contact us.

In the lab:

The power electronics laboratory is well

equipped for education as well as re-

search and development investigations.

The focus is on the small and medium

power rage. The AC-power supply is de-

signed for voltages up to 1000V and the

maximum (line)-power is up to 40kW.

In the lab a 500V/ 10kW- DC- network

is available, too. A wide spectrum of

measuring systems allows analysing the

EMI- behaviour as well as a high preci-

sion power determination. Combining

these with our infrared camera for ther-

mal investigations complex system tests

can be done. But it has to point out, that

outsourcing or a very rapid prototyping

can not be offered.

Research and development:

The focus of the institute is on high ef-

ficient PFC- stages. In Today’s topologies,

a bridge rectifier rectify the mains volt-

age. The output of the bridge rectifier

is connected to a boost converter. Input

rectifier and the PFC diode build up two

rectification stages. This reduces the ef-

ficiency more then necessary. Bridgeless

PFC’s have less conduction losses. Due

to the missing rectifier bridge bridgeless

PFC-converter causes a higher common

mode noise than with Today’s standard

boost converters. A simple and low cost

new L-C-EMI- filter was found out and

published. After that, a digitally control

circuit was designed. Also the input volt-

age respectively input current measuring

was optimized.

Some other investigations with industrial

partners are:

Thermal and electrical failure analysis

of solar inverters

Analysing of the influence of modern

diodes (SiC, GaAs) on the total PFC-

stage efficiency.

Influence of IGBT or MOSFET on the

efficiency in electronic ballast

Energy recovery inverter for agricultural

application

Analysing of thyristor- controlled arc

welding systems

neering and information technology. It

has a bridging function over these three

disciplines and deals with the functional

and constructional integration of these

FERDINAND-BRAUN-INSTITUT BERLIN

FBH’s Portfolio

The FBH is an internationally recognized

competence center for optoelectronic

and electronic research based on III-V

compound semiconductors. It operates

industry-compatible and flexible clean

room laboratories with vapor phase epi-

taxy units for the growth of GaAs- and

GaN-based epitaxial structures and a

III-V semiconductor process line for wafer

diameters up to 4 inches. The work relies

on comprehensive materials and process

analysis equipment, a state-of-the-art

device measurement environment, and

excellent tools for simulation and CAD.

In close cooperation with industry, its

research results lead to cutting-edge

products.

GaN Power Electronics at FBH

Gallium nitride (GaN) is characterized

by its excellent dielectric breakdown

strength. Thus, GaN-based High Electron

Mobility Transistors (HEMTs) offer excel-

lent power densities and combine high

electron mobility with high saturation

velocity. They are therefore well-suited

for high frequencies, high voltages and

very fast and low loss (efficient) switching

applications.

Innovative devices for power electronic

applications aim at achieving fast and ef-

ficient high-voltage switching capabilities

combined with normally-off behavior.

Our developments towards GaN power

HEMTs focus on increasing the break-

down voltage up to 1000 V. Further ob-

jectives are to develop and realize device

concepts for low on-state resistances

down to 10 m cm² as well as for normal-

ly-off devices. Accordingly, we optimize

epitaxial designs and growth procedures

as well as technological parameters and

specific features such as field plates, pas-

sivation layers, and layout designs com-

patible to high-voltage applications.

By concentrating electrons in the transis-

tor channel, high breakdown voltages are

achieved. Thus, corresponding epitaxial

layer designs are used providing a repel-

ling electrostatic force to the electrons

(back barrier designs). For normally-off

GaN power transistors, we are focusing

on p-GaN gate technology. This technol-

ogy renders the intrinsic potential distri-

bution close to the gate such that the de-

vices can only be switched on at positive

voltage. A threshold voltage of +1.5 V and

a gate dynamic range of +5 V are charac-

teristic values. Our high-current transis-

tors up to 150 A rely on a two-dimen-

sional scaling of the transistor width

considering thermal issues and combin-

ing it with flip-chip mounting capability.

The combination of these properties

qualifies FBH transistors for power ap-

plications in automotive electronics, ter-

restrial and space-borne solar converter

technology and others.

We are actively involved in various pro-

jects funded by industrial as well as pub-

lic national and European sources.

FRAUNHOFER INSTITUTE FOR RELIABILITY AND MICROINTEGRATION IZM

Power Electronics at Fraunhofer IZM

IZM has all necessary expertise in the

entire development chain, from system

design, packaging, thermal management,

electromagnetic compatibility, through to

reliability and damage analysis.

Electrical System & Circuit Design

Applications for power electronic compo-

nents are endless – in industrial drives, to

generate renewable energy, in transport

and more. The IZM is developing ground-

breaking solutions for demands such as:

High switching currents

High voltages

Very fast switching for SiC/GaN and

highspeed Si-devices

Mechanical stability

Strict EMC specifications

An extremely long lifetime

High reliability

Electromagnetic Compatibility

IZM is specialized in EMC and provides

consulting and research for all phases of

product development. Starting with basic

research into interference phenomena in

specific applications, we cover the entire

spectrum, including troubleshooting after

product delivery. We use in-house simu-

lation processes developed specifically for

frequent problems, as well as sophisti-

cated measurement series.

Thermal Management

The heat is dissipated from the chips

through various interfaces, thermal inter-

face materials, spreaders and substrates

before being released into the environ-

ment by a heat exchanger (cooler). All of

the specified points have to be optimized

to guarantee that the heat is removed

reliably and to meet the application’s

requirements.

Packaging

IZM has a wide area of packaging tech-

niques at its disposal:

Large-area solder joining; Ag sintering;

diffusion soldering/bonding

Heavy wire and ribbon bonding

Embedding technologies as well as

housing/encapsulation

X-ray and US microscopy, visual inspec-

tion and mechanic testing

Reliability

The damage behavior of materials and

components are carefully analyzed and

characterized in experiments; selected

material and geometry parameters can

be simulated (FEM). Technology-specific

material properties are a particular fo-

cus of measurement technology at IZM.

Among other things, such properties are

the key extending the lifetime of a solder

joint or a wire bond, and for measures

that improve reliability.

University of Bremen Institute for Electrical Drives, Power Electronics and Devices (IALB) Otto-Hahn-Allee NW1 28359 Bremen, Germany


www.ialb.uni-bremen.de

The Institute

The 1994 founded IALB focuses on

electrical drives, mechatronics, and re-

newable energy (Prof. Bernd Orlik) and

on power semiconductor components,

their environment, and applications (Prof.

Nando Kaminski, details see below).

Both fields are members of the Bremen

Center of Mechatronics (BCM, see www.

mechatronik-bcm.de).

Semiconductor Basics

Basic semiconductor physics and proper-

ties are investigated and modelled. A

special focus is on alternative semicon-

ductor materials like silicon carbide (SiC)

and gallium nitride (GaN), which play an

increasingly important role in power sem-

iconductor devices. The IALB operates a

deep level transient spectroscopy (DLTS)

and admittance spectroscopy equipment.

Device Concepts

The optimisation of existing components,

the investigation of new concepts, and

the modelling of devices are carried

out by means of simulation and in co-

operation with leading semiconductor

manufacturers e.g. Infineon and ABB.

Examples for current activities are the op-

timisation of the RC-IGBT with respect to

turn-off, snap-back, and diode behaviour

as well as the investigation of a novel

device concept for DC-switches. For semi-

conductor simulation DESSIS of Synopsis

Inc. is used, if necessary in mixed mode

with circuit and thermal simulation.

Packaging and Reliability

Housing technology and cooling affect

the reliability of semiconductor devices

significantly. A current core activity of the

IALB is the investigation of IGBT modules

under humidity, temperature and high

bias. Test facilities for climate and load

cycling are available. Another very impor-

tant aspect of the packaging is parasitics.

The determination of such components

is done by means of measurement and

simulation (ANSYS-Q3D by Ansoft Corp.),

respectively.

Application

The focus with respect to applications is

on the interaction between circuitry and

devices. In a current main activity IGBTs

and circuitry are optimised for resonant

switching. With rising switching speed

and frequencies parasitics play an increas-

ingly important role and affect the EMC-

performance considerably. This is investi-

gated by simulation and measurements.

Presentation

The research group on Power

Semiconductor Devices operating in the

Industrial Electronics Laboratory (DAEIMI

- LEI) – University of Cassino, is very active

in research dealing with modeling, simula-

tion, experimental characterization and

testing of power semiconductor devices

with a particular attention to the physical

mechanisms which cause the device failure

and impact on reliability and robustness of

the modern power semiconductor devices.

The research interests include the opera-

tions of power devices and modules at

high temperature and at the edges of

their safe operating area (short circuit,

overcurrent, inductive unclamped tests,

etc...). The research group has also ma-

tured a broad and deep experience in

the theoretical and experimental study of

Total Dose (TID) and Single Event Effects

(SEE) on power semiconductor devices

due to gamma, proton, neutron and

heavy ion irradiation.

Facilities

DAEMI-LEI laboratory houses a high-

voltage test room (Fig. 1) where various

equipments are hosted. Among them it

is worth mentioning the several versions

of non destructive power semiconductor

testers (ranging up to 5kA and 6.5kV)

where devices or modules under test are

operated in the presence of a protection

circuit which is able to prevent the device

failure at the occurrence of an instability.

The tests can be performed at case tem-

perature ranging from -50°C up to 200°C

ductor devices at temperature ranging from -50 °C

thanks to a special machine which is able

to convey directly on the samples under

test a pre-cooled/heated special fluid (Fig.

2). In such a way only the components

under test are brought to the desired

temperature without the need of cooling/

heating the whole apparatus.

The group is able to perform irradiation

tests according to the international stand-

ards and has also developed new irradia-

tion test methodologies which, together

Chair for Power Electronics and


At Chemnitz University of Technology,

the Chair of Power Electronics and

Electromagnetic Compatibility is respon-

sible for the education and research

regarding power devices, thermal-me-

chanical problems of power electronic

systems, power circuits and electromag-

netic compatibility.

Reliability and Ruggedness of Power

Devices

Ruggedness: Power devices must with-

stand overload conditions, they have to

be rugged. Short circuit capability of high

voltage IGBTs (SC I, SC II) is measured. A

further point is the surge current capa-

bility of Si and SiC diodes. The reverse

recovery behavior is of special interest.

Switching behavior and ruggedness of

high power diodes are investigated.

Experimental analysis goes along with

numerical device simulations. Detailed

analysis of the electro-thermal processes

in devices leads to design suggestions

for improved ruggedness. Additionally,

the group offers failure analysis, includ-

ing opening of the power module for a

profound analysis and the preparation

of failure reports including evaluation.

The group cooperates with Fraunhofer

ENAS and can use optimal analysis tools,

if necessary.

Reliability: Power devices are tested for

their reliability and durability on eight

self-built power cycling stations, between

100A and 400A, up to 2000A are in

construction. Power cycling is the most

important for life expectation of the

devices. Research work is focused on

detailed models for the failure mecha-

nisms. Thermal-mechanical simulations

are applied to illustrate local mechanical

stresses and strains in the device resulting

from the mismatch in the thermal expan-

sion of the material layers.

Additional reliability test stations are hot

reverse test (up to 2500V DC and 200°C)

and high-humidity high temperature re-

verse bias test.

The group is involved in various national

and international projects with global

players from semiconductor industry,

with automotive industry regarding

electric and hybrid electric vehicles, in

large offshore wind power, in inverters

for solar plants. The research in different

projects is supported by industry part-

ners, SINTEF Norway, the EU, BMWi and

BMBF, DFG and ESF/SAB.

Overview

The chair of Eletrical Drives was founded

in 1973 as 6th Chair of the Department of

Electrical, Electronic and Communications

Engineering.

Because of the variety of production ma-

chines, different motor types have been

developed over the years, which have

essentially been operated directly con-

nected to an electrical grid.

Due to the progress in microelectronics

and power semiconductor elements it is

increasingly possible to control the speed

of the motors digitally with the aid of

power-electronical converters. The sig-

nificant advantages of modern electrical

drive technology are improved energy

efficiency and improvement of the tech-

nical processes

The electrical drive technology entails the

following topics

electrical drives

power electronics

electrical machines

digital control

field buses

and their combination to the optimal drive

system for the respective application.

Research

Power electronics

Controlled electric drives often have to

decelerate electrically the motor with the

coupled mechanical load to a complete

stop. The kinetic energy stored in the drive

system shall be economically fed back

into the grid. For that purpose a new con-

verter topology is being analysed, whose

feedback inverter unit operates without

pulse-width modulation and works with

a smaller dc-link capacitor. Up to now,

Silicon elements (Si) have been used in

power electronics exclusively. But new

elements from silicon carbide (SiC) and

gallium nitride (GaN) feature substantial

advantages for power electronic applica-

tions. Therefore these new elements are

being tested for the application in con-

verters for electrical drives.

Digital control of three-phase drives

In many applications three-phase induc-

tion motors are used almost exclusively

today. Permanent-magnet synchronous

motors weigh less and are smaller in

volume and are more efficient at a com-

parable performance which make in-

novative solutions in chassis suspension

possible. The renouncement of a sensor

offers additional clearance. Therefore the

operation of a permanent-magnet syn-

chronous motor with sensorless controls

is being investigated.

Research from miniaturized electronic

devices to complex mechatronic

systems

FAPS concentrates its research activities

on innovative manufacturing technolo-

gies at all levels of mechatronics, from a

miniaturized device to a complex system.

For that purpose FAPS employs more than

80 dedicated researchers and technicians.

The Institute operates two laboratories

with a high-quality and state-of-the-art

machine and facility equipment on an area

of 2500 sqm.

A key research field of the institute FAPS is

packaging of electronic components and

the assembly of electronic devices with

the main process steps:

structuring and metallization of circuitry

(laser direct structuring, aerosol jetting,

plasmadust coating),

stencil printing and dispensing of solder

and sinter paste,

highly accurate component placement,

(high pressure) convection and (vacuum)

vapor phase soldering,

thin wire and thick wire bonding,

automated optical inspection,

reliability tests and lifetime modeling.

These core competences in electronics

production are used for development

of miniaturized PCBs, multi-functional

mechatronic integrated devices and high

performance connectivity and integration

technologies for power electronics. The

qualification of mechatronic devices is per-

formed by test systems for climatic, tem-

perature, vibrational and electric loads. A

well-equipped metallography and inspec-

tion equipment like CT included X-Ray or

confocal laser scanning microscopy can

be used for failure detection. Capable

software systems enable computer based

development and simulation of products,

processes and production facilities.

Additional to the field of electronic pro-

duction FAPS researches in the area of

bio-mechatronics, systems engineering

and electric drives technologies. A key

project is the E|Drive-Center where manu-

facturing technologies for electric drives

like winding, magnet assembly and metal

sheet packaging and the enhancement

of interconnection technologies between

electric drives and power electronics are

developed.

FAPS creates and realizes innovation

through the integration of knowledge

from different fields, in particular

disciplines of mechanics, electronics,

information technology, bionics and

optics,

integration levels from the component

to the system,

the entire product life cycle, from con-

cept, via development, production, use,

through to recycling,

by university research and teaching, in-

dustrial cooperation and spin-offs,

through sustainable and efficient meth-

ods for the production, distribution,

use, storage and reuse of resources.

technology and fabrication. Key interests

include development and simulation of

innovative production processes and

novel semiconductor devices as well

as optimizing equipment and materials

for micro, nano, and power electronics.

Electrical characterization of power elec-

tronic devices and development of power

electronic components are also part of

research activities of the chair.

The Chair of Electron Devices closely

cooperates with the Fraunhofer Institute

for Integrated Systems and Device

Technology IISB. Together, they run the

University’s clean room that provides

more than 1000 m2 of lab space for re-

search on processes and devices.

Novel Power Electronic Devices

Researchers at LEB investigate concepts

for manufacturing and optimizing in-

novative devices and corresponding

technology steps. Silicon-based semicon-

ductor devices and passive components

such as monolithically integrated RC

snubbers are an important field of study.

Research focus also lies on devices based

on silicon carbide (SiC). Besides pro-

cessing equipment for standard silicon

technology, facilities specially adapted to

requirements of SiC-device manufactur-

ing are available.

Energy Efficiency in Automobiles

The interdisciplinary group project

“TechFak EcoCar” is a student research

program to investigate efficient energy

usage in electrical automobiles. Students

of various fields of study, e.g., electrical

engineering, electronics and information

technology, mechatronics, power engi-

neering, mechanical engineering, mate-

rial sciences, and computer sciences, par-

ticipate in this project. An electric vehicle

as a testing platform allows students to

apply their theoretical knowledge and

gain practical experience.

Power Electronics and Control

Technology for Renewable Energies

The Power Electronics Department at

Fraunhofer ISE is specialized on the de-

velopment of highly efficient DC/DC con-

verters and inverters up to the megawatt

range. Our fields of work extend from

analog and digital circuit design through

layout up to digital control technology. The

department is organized in four groups,

which are focused on the following topics:

Module-Integrated Electronics and

Future Devices

We develop reliable and longlived

module-integrated electronics for harsh

environments. The potential for develop-

ing conventional transistors of silicon is

now largely exhausted. To progress our

developments further, we use the latest

power electronic components of silicon

carbide (SiC) and gallium nitride (GaN).

These components enable significantly

higher switching frequencies as well as

higher inverter efficiency.

String Inverters, Off-Grid Inverters

and Power Electronics for Energy

Storage

We develop power electronics, control

software and MPP-Trackers for string

inverters which meet the continually grow-

ing market demands and standards. The

rapid expansion of renewable energy re-

quires the integration of large-scale energy

storage units into the grid. We are devel-

oping innovative power electronics for this

purpose. We also offer our expertise for

off-grid power supply ranging from the

development of high-performance charge

controllers through highly efficient stand-

alone inverters to complex control technol-

ogy for photovoltaic hybrid systems.

Central Inverters and Solar Power

Plants

With the equipment in our megawatt lab-

oratory and our 5 MW outdoor test field,

we are able to develop, operate and test

central inverters up to a power of 1 MW.

Extremely accurate measurement technol-

ogy and special test equipment (e.g. a

»low voltage ride through« test facility)

enable us to test inverters according to the

currently valid specifications. Improving ef-

ficiency and reliability, reducing costs and

weight, and the demands of new feed-in

regulations for photovoltaic power plants

are the major topics for our research and

development activities.

Grid Integration and E-Mobility

We develop solutions and control algo-

rithms to integrate large proportions of

fluctuating power generated from re-

newable energy sources, and implement

grid-supporting and grid-forming func-

tions in inverters.

For plug-in hybrid vehicles and electric

vehicles we develop cable-based

bidirectional stationary rapid chargers

and on-board chargers as well as in-

ductive chargers. With the integration

of additional functions like compensa-

tion of harmonics, provision of reactive

power, grid support and low voltage ride

through (LVRT) capability, the chargers

are even able to improve the grid quality.

About

The Fraunhofer Institute for Applied Solid

State Physics IAF in Freiburg is one of the

world’s leading research institutes in III/V

semiconductor technology and modules.

Within its five business units Gallium

Nitride RF-Power Electronics takes a lead-

ing role. Fraunhofer IAF develops energy-

efficient solutions for energy conversion,

broadband communication systems, and

high data rate transmission, imaging, de-

tectors as well as semiconductor lasers. In

cooperation with a broad range of inter-

national project partners, Fraunhofer IAF

performs its expertise material and pro-

cess technology, in chip design, and in the

manufacturing of devices and modules.

In 2011, the institute had 280 employees

including more than 30 PhD students.

Power Electronics at IAF

Power electronics at IAF is based on the

development of Gallium Nitride (GaN) de-

vices. Overall, GaN-based devices are set

to have a direct impact on future efficient

power conversion systems and will thus

help save energy and miniaturize systems.

GaN technology is promising for auto-

motive, photovoltaic, IT- and consumer

applications as well as motor control and

appliances. Based on the longstanding

experience and the successful industri-

alization of GaN RF-processes in Europe

Fraunhofer IAF in power electronics con-

centrates on the critical aspects of:

Material growth

Process development

Characterization, chip- related packag-

ing, and reliability.

The need for ever-higher transistor per-

formances drives a continuous search for

improved epitaxy, process technology, and

advanced characterization.

Epitaxy

GaN-based devices with generically a wider

bandgap than silicon have a much higher

critical electrical field and, together with

high carrier concentration and high mobil-

ity, they offer superior trade-off of specific

on-state resistance RDS(ON) versus break-

down voltage rating and show low switch-

ing losses. For GaN to be cost effective

silicon reenters GaN devices as a substrate

material, which is a challenge regarding

defect reduction, overall material quality,

and overall process yield. Fraunhofer IAF

optimizes material growth with a strong

focus on material characterization.

Process Development

IAF’s baseline AlGaN/GaN high-voltage

process technology is based on devices

with standard 0.5 μm gate lengths. We

pursue performance improvement of

AlGaN/GaN-based devices for various volt-

age classes up to at least 600 V and cur-

rents currently as high as 100 A per chip.

Reliability and Characterization

Based on its strong RF- and microwave

background IAF concentrates on the

characterization of the static and losses

on devices level for the proposed increase

of the switching speed of the GaN-based

converters to the MHz range. Starting

from the material growth reliability is the

central aspects for high-power-density

devices.

We expect GaN to evolve in power electron-

ics driving performances to unprecedented

levels and to open new applications.

UNIVERSITY OF APPLIED SCIENCES ESSLINGEN

Prof Martin Neuburger Head of Department Power Electronics

Esslingen University of Applied Sciences Faculty of Mechatronics and

Electrical Engineering Robert-Bosch-Straße 1

73037 Göppingen, Germany


www6.hs-esslingen.de/en/18304

The Faculty of Mechatronics and

Electrical Engineering at Esslingen

University of Applied Sciences currently

comprises 24 full-time professors and

about 800 students who are mainly

working in the field of mechatronic

systems. The mechatronic approach of

the faculty is focused on combining and

integrating several scientific and techni-

cal disciplines in the design process of a

complex system, containing mechanical

and electronic components as well as

computer technology and software. To

realize such an overall approach, exper-

tise on system level is required as well

as detailed knowledge in several fields

of engineering sciences. Hence, besides

of control techniques, communications,

and manufacturing technology, power

electronics plays an important role in the

design of modern mechatronic systems.

The laboratory Machines and Drives, led

by Prof. M. Neuburger, is basically re-

sponsible for drive trains. Main tasks are

designing and validating electrical energy

converters and electrical machines, in-

cluding different types of electrical drives.

To achieve the required key performance

indicators, a multidisciplinary approach

is used, not only taking into account the

basic functional aspects, but also cover-

ing additional requirements and quality

parameters such as electromagnetic

compatibility (EMC), acoustics, or con-

struction dependent component place-

ment during all phases of the developing

process. This approach aims to tear down

the barriers historically grown between

several subjects of engineering sciences.

In this way, the overall performance of

a system can be optimized, rather than

having optimal partial solutions.

Examples of successfully realized projects

are a wireless power transmission for EV-

charging stations, or the setup of a com-

pletely self-designed wind energy plant

for small scale and home applications.

To achieve its research assignment, the

lab Machines and Drives has numerous

resources available. Besides of the pro-

fessors and the technical staff members

located in the lab and its several sub-labs

(e.g. high voltage lab, EMC lab, or electri-

cal drives lab) a photovoltaic test field is

available on the campus in Göppingen.

Unlike other photovoltaic power plants,

this test field is not operated in a com-

mercial environment, and hence allows

performing research projects without

limitations due to financial interests.

Besides of applied research, the main

task of the Faculty is education and train-

ing of highly qualified junior employees

for industry. To achieve this goal, differ-

ent study programs are offered. Besides

of the classical full time study program,

cooperative study programs and also

part time study programs are offered

for both, undergraduate and graduate

students. Moreover, doctoral programs

are also possible in cooperation with

other Universities. The excellent rank-

ing of the Faculty of Mechatronics and

Electrical Engineering indicates the high

level of education which is offered by the

Esslingen University of Applied Sciences

in general and at the site in Göppingen in

particular.

The Electric Drives and Machines Institute

at Graz University of Technology has a

long-standing tradition of research into

electric and electromechanical energy

converters, power electronics, and the

integration of these components into sys-

tems. Located in the second largest city

in Austria, it is part of a university with a

focus on the engineering and technical

sciences. The university includes some

12000 students and close to 2500 mem-

bers of staff, the institute is embedded in

a network with other universities within

the city, the country, Europe, and beyond,

thereby benefitting from a strong research

and increasingly international climate.

The competence of the institute was com-

plemented and extended in April 2010

when Prof. Muetze, who had worked

previously in Germany, the US, and the

UK, became head of the institute, further

directing the institute into an international

network of research and development ac-

tivities. The new leadership also brought

forth the construction of a new, modern

laboratory building for research and

teaching activities. This facility provides

around 300 m2 of floor space, up to 500

kVA power capabilities, including 690 V

systems and variable AC and DC voltages

up to 600 V, as well as the appropriate

modeling and measurement equipment.

A power electronics test laboratory is also

situated on the first floor to complement

the research in this area.

A significant part of the research activities

is carried out in cooperation with national

and international industrial partners,

covering the areas of electromechanical

as well as solid-state power converters,

design of power-electronics based sys-

tems including control and interactions

between system components, and the

development of prototypes and experi-

mental verification in the institute’s own

laboratories. With activities both in the

area of power electronics and in the field

of electric machines, the institute is ideally

placed to work on questions that arise

from power electronics to electric drive

systems applications.

Examples for current research projects

cover the wide range of topics from start-

ing of a line-operated synchronous ma-

chine with damper winding to the electric

and thermal design of drives for electric

traction applications, and small low-cost

drives of a few hundred Watts rated pow-

er for mass production. Further activities

include motor-inverter interactions, such

as inverter-induced bearing currents, and

the development of new power converter

topologies, such as a power supply reach-

ing titanium level efficiency for a wide

range of input voltages.

LABORATOIRE G2ELAB

The G2ELab is a university Lab, covering a

wide spectrum of expertise in the field of

Electrical Engineering, from material char-

acterization to system studies. The research

ranges from long term research up to col-

laborative research supported by a strong

involvement in partnerships with large com-

pagnies and SMEs. With more than 100

permanent staff, 110 PhD and 50 Masters,

G2Elab appears as a major actor both na-

tionally and internationally in these areas.

Power Electronics Group

While unconventional energy sources and

storage solutions have recently emerged,

power electronics increasingly rises to an

efficient interface between wide-ranging

sources and applications. The diffusion of

the power converters nowadays affects the

majority of industrial and mass consumption

domains over a large scale of power levels.

Our team (17 faculty members, roughly

30 PhD students) has chosen for the last

ten years to focus on ground breaking

researches. Those are aiming to improve

the design of the next electrical energy

management systems, both on the tech-

nological and conceptual level. Therefore,

power integration has become a unifying

topic in our team. We are working towards

conceiving and laying the technological

foundations required for our domain’s

improvement. The team is also pursuing

research on modeling tools development to

better answer our design needs for pack-

aging and electromagnetic compatibility.

To reach those goals, three interdependent

topics are investigated:

Research Topics

Integration technologies, both mono-

lithic and hybrid, from the chip to the

converter and its cooling system

The guiding principle of our investigations

is the system integration, while considering

the power converter’s environment. Four

projects are currently under study:

Passive components integration: inte-

grated L-C-T structures or multi func-

tional substrates,

Active components integration: multiple

floating potential devices and associated

electronic circuitries,

Heat transfer and spreading techniques

and their integration within power con-

verters,

Assembling and packaging of power

components: interconnects optimiza-

tion and coupled approach between

the power component and its electro-

thermal-mechanical environment.

Modeling and design tools for pas-

sive components and electromagnetic

systems

Power devices electromagnetic modeling is

mandatory as soon as the structure design

is started. This approach guarantees the

control over a maximal number of physical

parameters. This modeling is done with

a fine knowledge of components within

the structures and through the complete

system simulation. Two projects are devel-

oped:

Magnetic components modeling (coils

and transformers),

Modeling of any electric wiring (printed

circuit boards, thin wires, sheets, busbar).

Power converters design and promo-

tion for unconventional energies and

power grids

The general objective is the design of

switched-mode power supplies. This

research is focusing on the increasing

numbers of criteria imposed on the en-

vironment, in relation with the applica-

tions. Those criteria are divided into two

categories: compatibility with the con-

verter’s environment, both electrical and/

or thermal, and the volume power density

rise as a consequence of the integration.

These researches are mainly applied to

unconventional energies (fuel cells, solar

cells, uninterruptible power supply) such as

power converters for power grids (embed-

ded power grids for trains and airplanes,

electricity distribution networks).

The Institute‘s Profile

At the Institute for Drive Systems and

Power Electronics, experts for electrical

machines, power electronics and drive

control are working on research projects

covering the entire field of drive technol-

ogy, reaching from the microwatt to the

multi-megawatt range. A unique feature

of the IAL in the German-speaking part

of the world is the close co-operation of

two full professorships in drive technol-

ogy united in one institute, each of the

professors having approximately 10 years

of practical experience in industry.

The joining of the two formerly inde-

pendent institutes Electrical Machines

and Drives and Power Electronics to one

institute in 2001 reflects the technologi-

cal development towards integral overall

systems. On the one hand, this structure

is the ideal basis for a close co-operation,

and on the other hand, it offers distinct

expertise in both chairs.

The IAL presently consists of 2 full profes-

sors, 3 retired professors, 40 research asso-

ciates, 8 administrative and technical staff

members and approximately 50 students.

Chair of Electrical Machines and

Drive Systems

The main research work in the field of

electrical machines focuses on the de-

velopment of calculation methods and

software as well as on the research, pre-

calculation and elimination of technically

important parasitic effects like magneti-

cally excited noise, torque pulsations or

bearing currents.

The chair is actually held by Prof. Dr.-Ing.

Bernd Ponick, whose fields of activity

especially comprise harmonic field effects

in induction and synchronous machines,

small electrical machines and micro actu-

ators, combined analytical and numerical

calculation methods, transient phenom-

ena in drive systems, special effects con-

cerning converter-fed machines and fault

analysis in electrical drive systems.

Chair of Power Electronics and Drive

Control

The competences in the field of power

electronics are reaching from the charac-

terisation of power semiconductors and

the development of innovative gate drives,

the design and optimisation of power

electronic circuits including filters, to con-

verter control and modulation methods,

and the control of electric drives with or

without mechanical sensors.

The chair is held by Prof. Dr.-Ing. Axel

Mertens, whose fields of activity com-

prise applications of power electronics

and drives in hybrid and electric vehicles,

in wind energy and distributed power

generation, and in industrial applications.

Service Offers

Apart from the research work done

in semiconductor and micro systems

technology, ISIT offers many processing,

qualification, and test steps as a service

for our industrial customers. Many years

of experience with electronic assemblies

enables the engineers to elaborate solu-

tions in packaging processes, in manufac-

turing quality evaluation, in reliability and

lifetime testing, as well as in failure and

damage analysis. Within research pro-

jects, the design and production of appli-

cation specific power devices (MOSFETs,

IGBTs) has been accomplished.

Further Institute Highlights are:

Semiconductor production line in co-

operation with Vishay Siliconix Itzehoe

GmbH

IC Technology

Micro systems - MEMS

EN ISO 9001:2008 certified quality

management system

Packaging Technology

Conventional and advanced packaging

technologies are available, e.g. paste

printing, component or die placement,

and reflow soldering (vapour phase,

vacuum). Soldering process development

can be done by in-situ x-ray observation

of the melting process even with vacuum

applied. Semiconductor chip top connec-

tions are made by large wire bonding,

but new assembly concepts are evalu-

ated with wafer level chip size packages

(WLCSP) or with modified metallisations,

e.g. by wafer level NiAu plating on the

standard Al metallisation.

Quality and Reliability

Static and dynamic electrical measure-

ments confirm data sheet values, e.g. break

through voltage, on resistance, stationary

and transient thermal resistances. Several

power cycling test benches (current up to

2 kA) are available for reliability testing.

A dedicated power supply allows testing

of photo voltaic inverters (solar panel and

field simulation) and IR thermography

(Lock-In) is used to reveal hot spots.

Analysis is done by x-ray inspection,

scanning acoustic microscopy, scanning

electron microscopy, as well as by metal-

lographic cross sections.

Modelling

Modelling of thermal performance (ther-

mal resistance, stationary and transient)

has been applied to assemblies and cool-

ing units (air, water). Modelling of the

thermo-mechanical behaviour of assem-

blies and the damage mechanisms evalu-

ates critical loads and allows the predic-

tion of lifetime due to creep and fatigue.

KARLSRUHE INSTITUTE OF TECHNOLOGY (KIT)

Elektrotechnisches Institut (ETI) –

Institute of Electrical Engineering

The Institute of Electrical Engineering

(ETI) is a member of the Department of

Electrical Engineering and Information

Technology of the Karlsruhe Institute

of Technology (KIT). The institute was

established and built in the year 1895

by Engelbert Arnold. The institute is

currently led by Prof. Dr.-Ing. Michael

Braun, chair for Electrical Drives and

Power Electronics. In order to cope with

the current developments in electric

mobility a new chair focusing on hybrid

and electric vehicles was established in

2011. It is headed by Prof. Dr.-Ing. Martin

Doppelbauer. A colloquium with pres-

entations and discussions about current

research projects and innovative product

developments, organized by Prof. Dr.-Ing.

Helmut Späth (emeritus), is held regularly

at the institute.

Electrical Drives and Power

Electronics

Fields of activity and current research

projects:

Modular Multilevel Converters (new

topologies e. g. Modular Multilevel

Matrix Converter, control and balanc-

ing, drive applications, storage integra-

tion, grid access)

Novel power electronic systems (Quasi

Z-Source Inverter, Matrix Converter)

Short time storage systems with

Double Layer Capacitors

E-Mobility and Smart Grids (joint re-

search projects MeRegio Mobil and

IZEUS)

Control of High Efficiency Drives

(Permanent Magnet Synchronous

Motor with optimized performance,

using magnetic reluctance of an IPM-

Motor)

Power Electronic System Technology

(modular and flexible concepts for pro-

totyping and test stands)

Several converter systems with different

power levels (up to 300kW) are devel-

oped at the ETI. They can be used for

various applications, e.g. converters for

electrical machines, active-front-ends, as

DC-DC-Converter or in combination with

electrical energy storage systems for their

integration in the power grid. Their flex-

ible configuration and adjustment of the

signal processing allows a defined usage

in test and prototype systems.

Hybrid Electric Vehicles

The requirements for motors and power

electronics for the automotive industry

differ significantly from conventional de-

signs. An optimized design of an electric

drive train can only be achieved in an

interdisciplinary context. Therefore the

research fields are split into three focus

areas:

Mechanical Design

Power Drive System

Electromagnetic Design

For the characterization of prototypes

and for parameterization and validation

of simulations, three test stands are in

preparation. With a nominal power

of 145kW and 215kW, speeds to

18,000rpm or 15,000rpm and torques

of 270Nm to 540Nm they are an ideal

match of the power range of hybrid and

electric vehicles. In addition to studying

the dynamics of electric motors, drive

cycle analyzes can be performed.

University of Kassel Wilhelmshöher Allee 71 34121 Kassel, Germany


www.kdee.uni-kassel.de

The Centre of Competence for

Distributed Electric Power Technology

(KDEE) was founded to offer a concen-

tration point for the development of

innovative technical designs within the

university, enabling the transference of

solutions at both device and system level

to the industry. In terms of topics and

personnel it operates in close connection

with the chair of Electric Power Supply

Systems (EVS).

Power electronics-based converters are

the most flexible and dynamic equip-

ments for energy management in the

current and future electrical grid. Their

construction and control requires special-

ized knowledge, which is concentrated

and pursued on the long term. Hence,

the KDEE acts as a partner for industrial

and public-founded projects not only on

the fundamental research level but also

on industrial-oriented applications.

Teaching and research activities at the

department EVS are focused not only on

facilities and systems for electrical power

supply but also on the development of

power electronic components and de-

vices for such systems. These include the

development of methods to use renew-

able energy sources (e. g. solar energy,

small-hydro power, biogas and wind) as

well as power electronic converters for

automotive applications. A close cooper-

ation exists with the former “Institute for

Solar Energy Technology” (ISET e. V.), to-

day: Fraunhofer IWES (Institute for Wind

Energy and Energy System Technology),

which was founded 1988 by the for-

mer head of the EVS department Prof.

Werner Kleinkauf as well as with SMA

Solar Technology which has been a spin-

off company of EVS/University of Kassel.

With currently about 30 employees,

EVS and KDEE form a powerful research

group focused on the topic of en-

ergy supply systems at the University of

Kassel, diverse research possibilities and

wide-ranging study contents.

Main research areas:

Power electronic converters allow condi-

tioning of energy with high flexibility and

efficiency. This enables the integration of

different energy sources and storages in

a common energy system.

The main research areas of KDEE are:

Power electronic converters for distrib-

uted and renewable energy applica-

tions, especially solar and wind power

Characterization and application of

highly efficient power electronic semi-

conductors (Si, SiC, GaN)

Design of innovative magnetic compo-

nents for highly efficient and compact

The Department of Converter Technology

develops solutions for the grid connec-

tion of renewable energy sources and

energy storage, including the wired and

wireless grid connection of electrical

vehicles. We cover a power range from

a few watts up to several megawatts.

Our excellent competence is the design

and dimensioning of power electronics

converters, including the implementa-

tion of their control, for example DC / DC

converters and inverters. In our concepts

we follow a system oriented approach in

order to find optimal solutions for each

individual project/situation. Our research

topics are new converter topologies, en-

ergy efficiency, reliability and new control

algorithms.

Power Electronics and Components

The power electronics group’s task is the

development and optimization of circuits

for switching power converters as well as

components for renewable energy sourc-

es, energy storage and grid connection

of electric vehicles. In addition to improve

efficiency and reliability we also focus on

the optimization of the volume-weight-

cost of switching power converters.

Our development laboratories are well

equipped to perform demonstrations,

investigate components as well as char-

acterize and investigate final products.

Power Converter Control

The converter control group designs and

develops the control of power electronic

converters, which are often used as a link

between distributed generation plants

and the electrical power grid. Our focus

is on the development and optimiza-

tion of control strategies and control

algorithms that improve the behavior of

the converter of on-grid-connected and

off-grid-connected power plants thereby

increasing efficiency. Using Hardware-in-

the-loop and rapid-prototyping methods

accelerates our development process.

Testing

Testing of generation units, static converters

and power electronics is another essential

part of the research activities at Fraunhofer

IWES / Kassel. Within our accredited testing

laboratories, we offer standard and custom-

ized tests and measurements together with

characterization and simulation of power

electronics and system components, with

a particular focus on:

Grid integration

Performance and reliability

Electromagnetic compatibility

Our services cover concept design and

control systems as well as tests and

measurements of all power electronics

devices from sub kW to multi MW sys-

tems.

General Information

The University of Applied Sciences in Kiel

is the largest Applied Science Institution

in the State of Schleswig Holstein. In

2011 more than 6000 students were

enrolled with more than 1000 students

in the Faculty of Computer Science and

Electrical Engineering. The Institute for

Mechatronics as a part of the faculty

is offering education and research par-

ticipation for about 150 Bachelor and

Master Students.

The Key Aspect is E-Mobility

The Institute for Mechatronics has

a strong focus on E-Mobility and its

hardware components which led to the

establishment of the Schleswig Holstein

Competence Centre for E-Mobility

(www.fh-kiel.de/kesh). In research pro-

jects e.g. the daily use of electric vehicles

(Peugeot Ion, EcoCarrier) is analyzed and

a new battery management system is

developed. 5 Professors in the Institute

are offering specialized educational con-

tents like electrical traction and drives,

electrical circuit design, technical optics,

mechanical design, system modeling and

control techniques.

The Bonding and Joining Lab

Professor Ronald Eisele is part of the

E-Mobility-Team and his courses and

research capabilities in the labs are con-

sisting of:

Thermal modeling, simulation and de-

sign of systems and components

Electrical and thermal design of power-

modules

Professional assembly processes for

bonding joining tasks

Testing and characterizing of power

electronic components

These capabilities are also offered for

industrial development demands e.g. in

bilateral projects. By participating in re-

gional and nationwide research projects

these capabilities are constantly further

developed.

The scientific team includes experienced

engineers, Ph.D. Students (cooperative

graduations with other universities),

Bachelor and Master Students working

Efficiency and Sustainability (PEES)

Finland has a strong, globally operating

power electronics industry, and PEES at

Lappeenranta University of Technology

plays a significant role in the develop-

ment of Finland’s power electronics

industry.

PEES has around 70 employees (5 profes-

sors, c. 15 postdoctoral researchers, and

around 50 post-graduate students). The

PEES research teams work in tight col-

laboration in various application areas of

energy efficiency, energy conversion and

conditioning of energy. The PEES core

competencies are in electrical drives tech-

nology and in electricity power delivery

systems and regulation markets.

In the field of electrical drives technol-

ogy (Prof. Juha Pyrhönen), the research

achievements of high international level

are related to permanent magnet tech-

nology, control methods and power elec-

tronics applications (linear drives, mobile

drives, solid-rotor high-speed drives,

AC drive technology, wind generators,

model-based control of active magnet

bearings, modulator control of power

electronic devices, power line commu-

nication, medium-voltage converters,

smart drives, fuel cells). The research

achievements associated with electricity

markets and power systems (Prof. Jarmo

Partanen) include research activities re-

lated to low-voltage smart grids including

for example new distribution arrange-

ments based on DC systems or 1000 V

AC systems, control of loads instead of

production control, active energy storag-

es, utilization of passenger electric cars in

balancing the production and consump-

tion in the grid and different distributed

generation connected to the grid.


Efficient Energy Conversion Systems,

Electric Energy Storages and

Sustainability (PEECS)

PEECS is a PEES owned research program

focusing on the most significant applica-

tions of power electronics technologies

in industrial drives, distributed electricity

generation, smart grids, transportation,

and to some degree, domestic applica-

tions. PEECS contributes to energy effi-

ciency enhancement and cost reductions

by accurately controlling the electric

power flow and storage applying intel-

ligent power electronic control and by

replacing mechanical or hydraulic systems

with electrical drives utilizing digital con-

trol algorithms. Our PEECS research in-

frastructure is inevitably the strongest in

Finland in its own field. Research strength

is assessed based on the number and

productivity of the main researchers,

scientific output, number of graduated

doctors and international publications,

especially, the quality of the power elec-

tronics and drives laboratory – Motorium

Careliae (Figure 1), which on a European

and even global scale has excellent re-

search facilities with an infrastructure

characterized by 300 m2 of floor space

(+ other laboratories), 1 MW power loss

maximum, several test benches for motor

drives up to 1 MW. The maximum speed

available at 1 MW power is 12000 min-1.

The Industrial Electronics Lab (LEI) is ac-

tive in power electronics used in energy

conversion and energy storage, in model-

ling and simulation of systems, including

control strategies and control circuits.

LEI focuses its research activities along

three principal axes. The first concerns

power electronics, with the development

of new converter structures or topolo-

gies, or dedicated to specific applications.

Beneath many different application-

oriented options, LEI’s research activities

include a specific topic with an original

approach, namely the developing of

multilevel converters with symmetric and

asymmetric designs using medium fre-

quency transformation.

Other specific converter structures dedi-

cated to special generators or motors are

currently under developement.

The second axis of research concerns

the energy conversion in general, with

its management and storage. Flexibility

and rapid intervention are the main con-

tributions of power electronics in this

field which are particularly pertaining to

renewable energies – classical examples

of which are photovoltaic sources or vari-

able speed wind generators.

Among the applications developed at

LEI, supercapacitors for energy storage in

traction systems are worth mentioning.

They have been developed for several

vehicles, such as buses, diesel-electric

locomotives or light motorcycles.

Other new developments have recently

been presented, as the example of a

low aging, easy to recycle, hybrid energy

storage device based on compressed air.

These activities represent one aspect of a

tendency to realize so-called multidiscipli-

nary studies, as it is often needed in the

sector of energy. Another good example

of a multidisciplinary project realized at

LEI is the modeling of a Vanadium Redox

Flow Battery together with its auxiliaries,

or the model of a Hydrogen-Air Fuel Cell,

as it is defined as the third research axis

of the lab.

This third axis concerns the modelling

and simulation of systems, as well as the

concept and design of control strategies

and control circuits. In this field, many

new applications need to be investigated,

particularly complex and multidiscipli-

nary systems. In order to analyse the

functionality and characteristics of such

systems, new dedicated methodologies

are required. In this specific topic LEI is

using the EMR (Energetic Macroscopic

Representation) tool, as a systematic rep-

resentation method of the energy flow,

that allows the construction of the asso-

ciated Control Structure

SEEDS/ISP3D is a federation of 130

researchers form French electrical en-

gineering labs. The researchers share a

common but broad topic: integration

of power systems in 3D. Five other re-

searcher federations exist to work on the

societal challenge of energy: this large

group is untitled SEEDS as for Electrical

and Power Electronic Systems in Societal

Environment (www.seedsresearch.eu).

Research areas

SEEDS/ISP3D group focus many areas

related to integration of power systems.

It starts from materials for magnetic

integrated devices, high dielectric ceram-

ics, powders for alternative brazing of

chips in power module or special fluid

for integrated active cooling. Integration

of devices deals with passive devices (ca-

pacitors, inductance, transformer, super-

cap, battery cell), high-voltage wide

band-gap devices and high temperature

SOI devices. Functional integration is

experimented on silicon up to double-

face circuits. Efforts concern alternative

interconnection solutions of chips in a 3D

manner in a module.

Many results have been obtained on con-

verter architectures that benefit from 3D

integration like magnetically coupled poly-

phase converters. Converter architectures

are experimented to improve safety of

service and failure-mode operation.

Analyses of failure modes are carried out

on industrial and lab-scale modules to

feed research on lifetime prediction of

assemblies. Tests focus industrial applica-

tions in standard temperature range or

advanced power cores in extended tem-

perature range.

Innovative cooling approaches are pro-

posed within the semiconductor or at

package level. Passive cooling is ad-

dressed as well as active cooling based

on special fluids and motion schemes.

Wide bandgap devices are addressed

for high voltage applications and higher

ambient temperature. SiC, GaN and

diamond are experimented and differ-

ent levels of integration are considered.

Power devices have been tested between

-75°C to 300°C and more. Development

of dedicated drivers is hot topic. CMOS

SOI technology has been selected and

various driver test chips have already

been tested from -90°C to 300°C, mainly

in an attempt to exhibit failure modes

apart from functional verification.

Low-power monolithic integration receives

a lot of attention and challenging system-

on-chips have been demonstrated.

jects with competitive public funding

Research areas: Power Electronics,

Embedded Digital Systems and Power

Quality

Power Electronics activities at CEI are

related to Power Supply Systems of any

nature, ranging from low power (5mW)

cochlear implants to high power (100kW)

X-ray applications. However, most of the

activities deal with DC-DC, AC-DC or DC-

AC conversion

The traditional research areas of the

center are: power supply systems, power

management; energy efficiency, non-

linear control, modeling and simulation

of magnetic components, converters and

systems

This research has allowed the design

of high efficiency power supplies for

telecommunications, avionics, medical,

military and automotive industries.

The incorporation of nonlinear control

techniques, multi-phase converters and

digital control have improved substan-

tially the benefits of the converters and

opened the door to new applications

such as RF amplifiers. Recently, we are

working with wide bandgap devices,

both GaN and SiC, the development of

models for EMI / EMC and some renew-

able energy systems.

Power Conversion: DC-DC converters,

inverters and power factor correction.

Energy efficiency and high power den-

sity.

high frequency converter switching.

Modeling filters EMI / EMC for convert-

ers and systems.

Autonomous systems, battery charg-

ers, solar power micro-inverters, con-

verters for electric vehicles and energy

harvesting.

Research Topics Focus

Research is focused on new power

semiconductor devices in power electronic

circuits and systems: To make circuit and

system design appropriately profit from

the rapid development of devices com-

ing rather close to ideal switches, a basic

physical understanding of their operation

is required. On the other hand, device

development taking into account major

circuit or application-related requirements

can facilitate usage of the components op-

timised this way. To achieve viable results

in this respect, theoretical calculations and

simulations need to be complemented by

experimental work in laboratory.

The interaction between component, cir-

cuit and system is influenced on such dif-

ferent levels as circuit elements including

parasitics, drivers, control methods and

operational conditions of the system. To

a large extent, power supplies or electric

drives are investigated, aiming at applica-

tions such as in the fields of renewable

energy, automotive electronics, welding

sources or appliances.

Topic EMC

The switching slopes of the power semi-

conductors cause conducted and radi-

ated emissions of the system which need

to be limited according to standards to

avoid disturbances of the power elec-

tronic or other equipment. The propa-

gation of these disturbances is strongly

influenced by capacitive and inductive

parasitic elements, thus a detailed inves-

tigation of power section – comprising

mechanical construction, semiconductor

devices and their control – is required to

achieve an optimisation.

Topic Reliability

Power semiconductor devices typically

consist of a chip which is packaged in a

structure of several conductive and isolat-

ing layers. Several known mechanisms

limit lifetime. Those can be triggered by

operational conditions, e. g. load cycles

leading to thermo-mechanical stress and

subsequent fatigue. Again, the require-

ments defined by increasingly demanding

applications – e.g. cycles in traction, elec-

tromobility or wind generators – need to

be determined and appropriately applied

to the devices’ capabilities as qualified in

standardised tests.

Research Environment

With a mixed team of experienced and

young scientists and a state-of-the-art

infrastructure of power electronic labo-

ratories and computer equipment with

relevant simulation software, a variety of

research projects in the aforementioned

fields have successfully been carried out.

Students are involved, providing them an

education to become the next generation

of experts in the field of power electron-

ics with its increasing importance as key

technology for energy efficiency and us-

age of electrical energy generated from

renewable sources.

The use of power converters has become

very popular over recent decades for a

wide-range of applications, including

drives, energy conversion, traction, and

distributed generation. The control of

power converters has been studied ex-

tensively.

Currently the controller designs are de-

cided by two trends: the digital signal

processors (DSPs), which are sequential

processing devices where their charac-

teristics and programming methods are

well-known. The FPGA’s are reconfigur-

able digital logic devices, which contain

a variety of programmable logic blocks,

and can be configured using the hard-

ware description language (HDL). The

main advantages of FPGA over the se-

quential hardware of DSPs are their wide

parallelism, deep pipelining, and flexible

memory architecture. With the dramatic

increase in logic element density, clock

frequency, and advanced intellectual

property (IP) cases, such as floating-point

arithmetic, FPGAs show great potential

for real-time hardware emulation, control

applications, power electronics’ applica-

tions such as motor control, active power

filters, DC/DC power converters or multi-

level inverters.

New methods for the modelling, analy-

sis, and logic control design of industrial

production systems are being developed

at the Institute of Robotics. The devel-

opment of rapid prototyping tools and

techniques is one of the most impor-

tant issues at the Institute of Robotics.

The use of techniques such as the dy-

namic emulation of mechanical loads,

enables a reduced time-to-product with

enhanced testing and evaluation pos-

sibilities, even during the pre-prototype

design phase. The Institute of Robotics

is well-connected with very important

industrial companies in Slovenia such as

Iskra Avtoelektrika, DOMEL, TECES, etc.,

as well as European companies such as

Daimler-Stuttgart, Fiat, and STM-Catania.

Research and development activities and

interests:

Control algorithms for the control

of servodrives, as applied in electric

powertrain and auxiliary devices. Our

field of expertise covers the control of

induction and PM motors.

Power electronics’ converters (equip-

ment and control algorithms) used for

the powertrain and auxiliary devices

in a power range from a few watts

to some hundreds of kw. Besides

the design of these inverters we also

designed the control hardware and

software, and recently also applying

the FPGA hardware. Issues of EMI and

thermal modelling are among the ac-

tivities of our research group.

Advanced test stands for vehicle de-

sign (rapid prototyping tools and tech-

niques).

Hardware and software for system

integration, management, and moni-

toring, with special emphasis on power

management and power sources’/

loads’ interconnection.

Integration of control hardware and

software based on microcontrollers,

DSPs, and/or FPGAs.

The research institute Swerea IVF is a

subsidiary of the Swerea group, a con-

glomerate of Swedish research institutes

within the fields of materials, process,

product, and production technology.

Swerea IVF’s staff of about 150 carries

out applied research, offer qualified re-

search and consultancy services and have

extensive experience of participating in

international projects, as well as of initiat-

ing and coordinating them.

The main goal of Swerea IVF is to assist

in the rapid introduction of new tech-

nologies and methods to practical use in

our customers’ operations. Our custom-

ers include industrial companies as well

as public institutions that turn to us to

develop their future resource efficient

products and processes.

Electronics Packaging and Reliability

Swerea IVF has more than 25 years expe-

rience in electronics packaging and reli-

ability. Materials and failure analysis, both

non destructive and destructive, are im-

portant tools in the reliability assessment.

To that end we maintain sample prepara-

tion, testing, and analysis labs including

SEM, Scanning Acoustic Microscopy, and

Micro Focus X-ray equipment. We assess

the reliability of new packaging concepts

in research projects as well as for specific

products, notably field returns, at the re-

quest of individual companies.

One example of a strong research effort

is Swerea IVF’s activities since 1997 in the

area of Dye-sensitized solar cells which

focus on the development of materials,

manufacturing processes, upscaling and

reliability testing of prototypes where

we are working in a close collaboration

with the Royal Institute of Technology in

Stockholm (KTH), Uppsala University, and

Dyenamo AB.

The Electronics Packaging and Reliability

group together with the Ceramics

group of the Department of Materials

Applications perform research within the

area of high performance electronics with

ceramic packaging solutions. In the past

5 years the research has had strong focus

on high temperature applications of GaN

sensors and SiC power electronics. Swerea

IVF to this end works with additive direct

manufacturing technologies for packag-

ing which allows highly integrated power

electronics and cooling solutions.

Recent power electronics packaging

research focuses on a solution with a

stacked structure that allows for double

sided cooling using Fairchild BJTs and

Cree MOSFETs.

Swerea IVF is currently coordinating

COSIVU, an FP 7 project on an electric

wheel motor drive system with SiC power

electronics.

Large electric drives

(Traction,electric ships, electric aircraft)

Electric vehicle drives

(LEV, electric passenger cars)

and new Converter architectures enabling

Modular, scalable hardware

Fault tolerant operation

Fully digital control and integrated sen-

sors

These systems are developed and investi-

gated thoroughly with respect to indus-

trial feasibility. The equipment at IPEC

includes laboratories for investigation of

High Power Converters up to 20kV in the

MW-Range and Electric Drives up to 1kV

in the 100kW-Range.

Advanced Multilevel-Converters for

High- and Medium-Voltage

High Voltage Direct Current Transmission

(HVDC) is becoming a key enabling

technology for the integration of regen-

erative sources into the grid. While the

conventional AC-Networks are getting

more and more inefficient or unstable

under the new conditons, an electroni-

cally controlled DC-Grid will be extremely

valuable.

Advanced Multilevel-Converters are

the most promising systems for these

requirements. New concepts, suitable

for these applications, are developed at

IPEC (E.g.: Modular Multilevel Converter,

M2C). Research is concentrated on in-

dustrial scalability, safety, fault tolerant

operation and the digital control system.

At the control side, the new systems of-

fer vastly extended degrees of freedom.

Therefore, many research projects are

focused on new digital control schemes,

for improved exploitation of these new

possibilities.

Large Drives with Medium-Voltage repre-

sent another important field for Modular

Multilevel Converters , applied e.g. for

industrial drives and electric Ships.

Ultra light converters for mobile ap-

plications (MHF)

The successful development results of

Multilevel-Converter for the High Power

range has led to a significant extension

of research projects , focused on mobile

applications. In this area, industrial scal-

ability ,modularity of the hardware and

fault tolerant operation are very impor-

tant, too. Additionally, ultra light weight

and minimized space are essential points.

These requirements are best met by new

multilevel topologies, which allow for

the elimination of passive filters. New

converter topologies (MHF) enabling and

integrated contol and sensors are devel-

oped and investigated in several research

projects.

active in research on novel electromag-

netic devices, power electronics and

derived systems, estimation and control.

Research activities cover various applica-

tions of electric drives starting from small

low-cost drives for household applica-

tions to high efficient wind power gen-

erators. PEDM is very active in automo-

tive and aerospace applications, working

closely together with OEMs, Tier 1 and

Tier 2 suppliers on new cost-effective

solutions. It comprises nine members of

academic staff, supported by approxi-

mately 15 Research Associates and 32

PhD students, with a strong record on

Example 1: Power dc/dc Converter for

Hybrid Electric Vehicles – New project

To realize the potential of fuel cell and

hybrid technologies in bus, truck and

high performance vehicles, a step change

is required in the performance of the DC-

DC converter systems that interconnect

the fuel cell, energy storage device and

traction drive. The project addresses this

technology gap through the develop-

ment of more compact, lower cost, high-

ly efficient DC-DC converter techniques.

Funding has been received to develop a

novel control algorithm that allows the

reduction of the inductor in a dc/dc con-

verter by 50% without the use of new

materials or the increase of the switching

frequency. PEDM demonstrated the new

controller already on a low power dc/dc

converter.

Example 2: Efficient Drive for Aerospace

to the field. The research team also has

35 Postdoctoral Research Fellows and 40

PhD students. Funding for the Group’s

research (current portfolio £18M) comes

from a diverse range of national/interna-

tional agencies and industry. Reflecting

the Group’s expansion and success,

2010/2011 saw new investment from in-

ternal and external sources of £2.5M for

infrastructure developments and equip-

ment to support Group activities.

Core technology expertise of the

Group covers 4 main areas:

Power Electronic Energy Conversion,

Conditioning and Control

Power Electronics Integration,

Packaging and Thermal Management

Motor Drives and Motor Control

Electrical Machines.

The Group strategy is to sustain an in-

house, internationally renowned research

capability and portfolio spanning the

entire range from power device and com-

ponent technology to complete power

conversion systems. The PEMC Group

collaborates closely with complementary

groups at Nottingham, and with a number

of other Groups in the UK and worldwide.

Research activities cover basic technology

(e.g. physics of failure research) to applied

research (e.g. professionally engineered

advanced technology demonstrator hard-

ware for aerospace industries).

The PEMC Group has very strong links

with industry, both nationally and in-

ternationally, ranging from component

suppliers to OEMs, where it applies its

core technology expertise to application

oriented research. The portfolio of ap-

plications is currently orientated towards

aerospace (for example through the

Clean Sky JTI), renewable/sustainable

energy and future energy networks, but

it continually evolves to reflect to new

opportunities and challenges. Other sig-

nificant industrial collaborations exist in

marine systems, industrial drive systems

and power conversion for high power RF

sources.

Research in the Group is underpinned by

world class experimental and workshop

facilities allowing realistic practical valida-

tion of novel components and systems.

Work up to 1MVA (continuous) is possi-

ble where appropriate. Specialist facilities

exist for power device packaging re-

search and reliability studies, for in-house

prototype electrical machine construction

and testing (up to 120,000rpm) and for

power converter construction. Dedicated

electronic supplies provide emulation

of aircraft generation systems up to

270kVA. Extensive modelling capabilities

also exist with expertise in most of the

established simulation and CAD environ-

ments. As a demonstration of capabili-

ties, recent projects have seen the devel-

opment and delivery of a 600kVA grid

interface converter, a Silicon Carbide JFET

matrix converter (power density 20kW/L),

a 150kV, 150kW resonant power con-

verter for high power RF applications and

a novel 85,000rpm machine for transport

applications.

The Power Electronics Laboratory (PEL)

of the University of Padova performs

state-of-art research in several areas of

industrial and consumer power electron-

ics. It has been operating since the early

80’s in the development of topologies

and control strategies related to energy

conversion. The PEL research group in-

cludes two full professors, three associate

professors and one assistant professor,

plus several Ph.D. students and research

fellows.

Current research areas of particular rel-

evance for PEL are the following.

Power Device Technology

As new switch technologies arise, the

performance characterization of novel

power switching devices becomes a

major research topic. PEL is active in test-

ing and developing applications for SiC

based and GaN based power devices.

Digital Control

Digital control of switched-mode power

supplies has been a mainstream research

topic at PEL in recent years, mainly tar-

geting the study and development of

fast, highly optimized and integration-ori-

ented digital controllers for high-frequen-

cy DC/DC converters. Recent projects

focus on digital control of automotive

LED drivers with fast dimming capabili-

ties, smart power management solutions

for energy harvesting systems, and online

efficiency optimization techniques for

resonant topologies.

Renewable energy

Development of novel converter topolo-

gies and control structures for the intel-

ligent exploitation of renewable energy

sources is another key activity of our

research group, with focus on interface

converters for photovoltaic generators,

batteries and PEM fuel cells.

Solid State Lighting

Design of line-fed converters for light-

ing is a traditional research area for PEL.

Recently, special attention has been

devoted to the development of novel

converter solutions for LED lamps, in

particular those based on high-frequency

resonant converters.

Smart grids

The Power Electronics Laboratory is part

of a multi-disciplinary research team

including experts in Power Systems,

Telecom, Economics, Measurements, and

Control. The group mission is to perform

cutting-edge research on smart micro-

grid (S�G) technology, particularly focus-

ing on the following issues.

Distributed control algorithms: this re-

search relates to distributed, online and

quasi-optimal policies for: 1) control of

distributed micro-generation from, e.g.,

renewable energy sources, 2) real-time

cooperative control of active elements

(e.g., inverters), 3) real-time power sched-

uling for distributed residential scenarios.

Distributed energy storage: this research

deals with optimum control of distributed

energy storage to meet the SG require-

ments while maximizing the exploitation

and lifetime of batteries (optimization of

charging cycles, minimization of energy

exchanges, etc).

Real-time simulation and HIL: this activity

relates with dynamic analysis of actual

micro-grids and testing of real-time con-

trol algorithms in the smart micro-grid

experimental facility.

New communication paradigms for SG

control and monitoring: this activity aims

at the development of communication

architectures suitable for SGs, including

aspect of security and privacy.

Department of Electrical Engineering

and Electrophysics

The Department of Electrical Engineering

and Electrophysics of the Institute of

Thermomechanics AS CR, v.v.i. is en-

gaged in the analysis and modeling of

electric drives and rotating machines

along with the experimental verification

of the achieved results. The most impor-

tant methods for the conversion of me-

chanical energy into electrical energy and

vice versa are analysed. Research is also

focused on current problems connected

with the circuit structures of power elec-

tronic converters and algorithms of the

digital control and diagnostics of these

converters. The mutual effects of power

electronic converters with both the ma-

chines that are supplied from them and

the supply networks to which they are

connected are analysed.

Considerable attention is given to sys-

tems with doubly fed machines, which

can operate at variable speeds and are

thus perspective generators for wind and

hydro power plants. The possibility of

setting suitable speeds makes the energy

conversions more efficient, improves the

technical parameters, and extends the

lifetime of the machinery. The goal of

increasing the reliability of variable-speed

drives is to propose measures for keep-

ing a drive in operation even if some of

its components fail. A related area of

research is the compensation of unbal-

anced three-phase power supplies of

semiconductor converters that can, in

practice, result in the significant deterio-

ration of the operating characteristics of

electric drives.

Advanced control algorithms of AC drives

are developed and tested experimentally

with prospective utilization in industry

and traction. A power supply from mul-

tilevel frequency converters is developed

for these drives. Studies focus on the

unfavorable high-frequency phenomena

(EMI) due to operation of the converters.

Models of the individual components of

the drives, also valid for high frequencies,

are proposed and experimentally verified.

As far as the electromagnetic compatibil-

ity (EMC) in electric power engineering

and the quality of electrical energy are

concerned, algorithms are developed to

control the active power filters with the

goal being to compensate for higher har-

monics, unbalanced loads, power factor

and flicker, and to control energy flows in

transmission, distribution, and industrial

networks.

www.rbzentrum.de

The rbz – a research and teaching

network

The Robert Bosch Center for Power

Electronics (rbz) is a research and teach-

ing network established in 2009 in

which the Bosch Group, Reutlingen

University and the University of Stuttgart

have joined forces. This unique coopera-

tion is the first of its kind in Germany.

In order to set up and operate the rbz,

the Bosch Group, the state of Baden-

Württemberg and the universities com-

mitted themselves to invest more than 30

million Euros over the next ten years for

new chairs and infrastructure. The Robert

Bosch Center for Power Electronics has

branches in Reutlingen and Stuttgart. At

the rbz students can take Bachelor's and

Master's degree programs that focus on

power- and microelectronics. They can

study in Stuttgart or Reutlingen, depend-

ing on the program chosen. There is also

the possibility of studying for a doctorate.

The rbz in Reutlingen

At the rbz in Reutlingen three new chairs

have been established. These professors

are responsible for teaching in the

Master's program for Power Electronics

and Microelectronics as well as for

conducting research in these fields.

Prof. Dr.-Ing. Martin Pfost, professor

for Power Electronics, was working for

eleven years at Infineon Technologies

in Munich and Bucharest at different

positions in GaAs-, SiGe- and Si-power-

technology modeling and safe operating

area simulation.

Prof. Dr.-Ing. Jürgen Scheible, professor

for Electronic Design Automation, gained

over 18 years of working experience at

Robert Bosch GmbH where he was in

charge of layout design and methodol-

ogy, improvement of design flows, tool

management and ASIC layout design.

Prof. Dr.-Ing. Bernhard Wicht, profes-

sor for Integrated Circuit Design, also

came straight from the industry. At Texas

Instruments, Freising, he was working as

analog ASIC designer and design man-

ager for power & networking.

Their research interests comprise char-

acterization, modeling, and optimization

of power semiconductors and power

electronic systems, methods for automa-

tion of ASIC layout design, IC design

with focus on power management, gate

drivers, motor control, energy efficiency,

low-power, ESD and EMC. Many research

projects from these fields have already

been started. Some are concerned with

the prediction of safe operating area and

lifetime modeling of advanced power

semiconductors. Other projects deal with

improved layout generators and con-

straint-driven design methodologies, DC

converters operating in the MHz range as

well as optimized gate drivers. More top-

ics not mentioned here are addressed in

ongoing research activities.

As of 2013, thirteen Ph.D. students

who work towards their doctorate in

Reutlingen and two Postdocs assist the

three professors in their research pro-

jects. Further growth is expected.

The research activities concentrate on

medium and high power semiconduc-

tors and their application in inverters for

electrical drives and energy transmission.

The scientific staff involved with power

electronics and electrical drives consists

of more than ten research assistants.

Power semiconductors

In the field of power semiconductors,

FEM device simulations as well as switch-

ing measurements are carried out.

Devices under test are high voltage IGBTs

and diodes and SiC transistors. Research

topics are:

Static, dynamic and failure behaviour

of power semiconductors.

Besides the standard measurements of

the switching behaviour, the focus lays

on the measurement of the behaviour

of IGBTs and diodes in case of short

circuits in the load, and on the evalu-

ation of the behaviour of inverters in

case of a failure of the power semicon-

ductor.

Interaction between power semicon-

ductors and their gate drives.

Aim of this work is to gain a deep

insight into the device physics and the

effects of parasitics in the power- and

the control-circuit during switching.

The results are used for the develop-

ment of gate drive circuits for op-

timised switching and short-circuit

behaviour.

Modelling of the switching behaviour

of IGBT for the use in circuit simulators.

A physical based, analytical model of

the switching transients of IGBTs is de-

veloped, which can be parametrised by

measurements.

The power electronics laboratory is

equipped with several test benches for

multi-pulse and continuous operation

tests with dc-link voltages up to 7.5 kV,

load currents up to 2 kA for continuous

operation, more than 10 kA in multi-

pulse sequences (tens of ms) and up to

1 MA in case of device failures (hundred

of μs). In the high current lab, surge cur-

rent tests with more than 50 kA (sinus

half wave) and continuous current tests

with up to 2 kA – also under defined cli-

matic conditions – can be carried out.

Inverters and drive systems

The research activities in this field include

topologies for multi-level inverters, con-

trol and protection of wind power plants,

interactions between inverter fed electri-

cal drives and the power grid, behaviour

of island grids in offshore windfarms.

Besides state-of-the-art simulation tools,

test setups with electrical machines and

inverters up to 50 kW are available.

converters (Design and manufacturing

of demonstrator; Validation of basic

technologies; Integration numeric-

power);

Architecture, system and technology

management for electrical energy stor-

age in fixed or onboard systems.

PRIMES is succeeding to the PEARL

Laboratory and take the benefit of its

10 last years of experience in applied re-

search as well as in the use of very highly

equipped platform.

One of the major challenges for Primes is

to enable the maturity of new industrial

channel aiming at the manufacturing of

new wide gap components that could

be sold to the transport Industries (aero-

nautics, railway, automotive) as well as to

the industrials dealing with the manage-

ment of energy, with facilities to design,

develop and test integrated power con-

verters and test power systems like trac-

tion drives or any inboard systems.

In particular, PRIMES puts a huge ef-

fort in developing virtual prototyping

solutions for power electronic systems,

combined to a prototyping and charac-

terization platform to be able to design,

simulate, manufacture and character-

ize new power module technologies.

In a technological point of view, PRIMES

has developed several integration tech-

nologies, for insulating or conductive ma-

terials to electrical system topologies.

PRIMES has experience and is certified

for the industrial development of power

switches for avionic/aerospace applica-

tions and be confident with innovative

interconnect, packaging and cooling

solutions. PRIMES includes a power

switch manufacturer of proven experi-

ence in the avionic domain (linked to

AeroSpace Valley competitively Pole), and

is equipped and resourced to provide the

type and number of innovative power

modules required for any program.

PRIMES is a key platform for power inte-

gration innovations in Europe.

The laboratory

The Laboratory of New Technologies is a

lab of the IFSTTAR institute. Its proficiency

concerns the power electronics applied to

transport systems, traction applications

(automotive and railway) and electric ac-

tuators (aircraft), with a technological ap-

proach of components (semi-conductors,

ultra-capacitors, fuel cells,…). The global

approach is to contribute to the knowl-

edge of the behavior of new devices sub-

jected to their usage conditions, to study

their integration in the transport modes

and to promote the development of

electric and hybrid transport systems. It is

involved in original research in the domain

of the reliability testing of power semicon-

ductor devices, the storage of electrical

energy for urban transport systems and

the integration and interface systems of

fuel cell generators.

Key research fields

Robustness & Reliability of Power

semiconductor devices and integrated

systems

Investigations are especially conducted

for high voltage and high temperature

power semiconductor devices and power

modules. In this field, the research focus

is in one hand the assessment of power

devices lifetime and on other hand on the

understanding of the physical mechanisms

of degradation and aging phenomena of

power IGBT modules and new wide band

gap based semiconductor devices (SiC,

GaN).

Reliability of Energy storage systems

for transport applications (Ultra-Caps)

Works concern the behavior of ultra-cap

devices and systems against ageing by

successive charge and discharge cycles.

The goal is the understanding of their be-

havior in usage conditions. Effects of test

parameters (temperature, voltage, cur-

rent, ...) are evaluated in order to high-

light the key factors involved in failure

modes and to control the reliability and

security of the energy storage systems.

Fuel Cell generator systems for trans-

port applications

The research activities conducted on fuel

cell generators are closely linked with

actual contexts of electrical vehicle and

reduction in greenhouse gas emission.

The focus is done on experimentation

and integration of fuel cell systems in the

transport environment (characterization,

performance improvement, endurance,

reliability and diagnostics). It is also con-

sidered degradation modes and fault

tolerance of fuel cells.

Competence areas

Reliability testing (ageing tests by power

cycling, thermal cycling)

Search for ageing indicators (damage

detection)

Si (power IGBT modules) and WBG (SiC

and GaN) devices

Electrical characterization in high

power range (4kV-6kA from –40°C to

125°C, 20A-6kV @250°C)

Thermal characterizations (Rth, Zth,

transient thermal analyses,…)

IR thermography

Physics of failure (Failure analyses, fail-

ure mechanism investigations)

Multi-physic modeling (electro-thermal,

thermo-mechanical)

The Institute of Energy Systems and

Electrical Drives was merged in 2011

from the institute of “Electrical power

systems”, “Electrical drives and ma-

chines” and the “Energy economics

group”. Our department is active in the

area of the design of electric machines,

as well as their regulation. Of course the

power electronics may not be disregard-

ed in the drive technology.

Due to the trend of repairing com-

ponents just before a problem arises,

monitoring is also a topic in our field of

research. One domain is the monitoring

of induction machines where the squirrel

cage is examined for a breaking bar. In

the view of life time, the inverter’s weak-

est component is the DC link capacitor.

So another domain is the monitoring of

these capacitors of an inverter without

additional components in the power path

of the inverter.

The main focus of our research is the

highly dynamically sensorless control of

permanent magnet synchronous ma-

chines (PMSM). Sensorless means you do

not need any mechanical speed or posi-

tion sensor. At high speed we use the

well known back EMF method. At low

speed and at standstill this model will

not work due to the lack of the stator

voltage. So we developed the so called

INFORM method which uses the machine

itself as a sensor. Therefore some test

pulses are applied to the machine and

the response can be used to calculate the

actual angular speed of the motor shaft

which is needed for a field orientated

control of the PMSM. Latest develop-

ments are aimed to include these test

pules into the normal operating mode.

So the noise of the INFORM test pulses

will be negligible.

The INFORM method is independent of

the size of the motor. As an example for

small drive applications, we implemented

the INFORM method together with a

dental company in their products. So we

solved their former problem of damaged

Hall sensors during high temperature

sterilization (Hall sensors can be used

for the field orientated control of the

PMSM). Now they are able to cover the

whole range of speed with one drive

and can serve additional applications

where full control of speed and torque

is needed. As a high torque application

example, we designed a traction machine

for propulsion with the scope of good

sensorless properties. So the drive is able

to be highly overloaded and even be con-

trolled without sensor. In the figure the

4kNm prototype is shown.

As mentioned, the INFORM method is

independent of the size of the machine.

We are able to control small machines

with a few mNm at very wide speed

range up to torque motors in the range

of several kNm at low speed. Therefore

no speed or position sensor is needed

even at low speed and standstill.

Warwick University is home to the Energy

Conversion Research Group where lead-

ing research on power electronics is

performed. Significant investment from

the UK government and industry has

contributed to the development of a

silicon carbide dedicated cleanroom and

a power electronics laboratory. Research

into power electronics for automotive

and energy transmission/distributtion

systems has recently been funded leading

to a centre of excellence in power elec-

tronics. The Energy Conversion Research

Group at Warwick University is engaged

in the following research activities

Silicon Carbide:

The European Regional Development

Fund together with the West-Mindlands

Regional Development Agency have

invested over £10 million into the devel-

opment of a silicon carbide dedicated

processing facility at Warwick University.

Using wide bandgap semiconductors like

silicon carbide, significant improvements

in the efficiency of energy conversion

can be achieved. Energy efficient power

converters for automotive and power

systems based on silicon carbide are con-

tinously being demonstrated.

Vehicle Electrical Systems Integration :

This project was funded by the British

government to the tune of over £3 mil-

lion. The project involves the develop-

ment and optimization of Electric Vehicle

systems architecture for improved energy

conversion and management. Research

into silicon carbide. Prof. Mawby is lead-

ing a consortium of several UK universi-

ties in delivering this project.

High Voltage SiC Devices for the

Future Grid:

Warwick University has also recieved

funding from the British government to

develop the SiC power devices for the

future electrical grid. With the increased

integration of renewable energy into the

grid, advanced power electronics will be

required to ensure stability, controllabil-

ity and flexibility especially since energy

sources are intermittent and unpredict-

able.

Advanced Packaing Technology:

The Energy conversion group at Warwick

University also conducts research into

advanced packaging solutions for high

temperature/high frequency applications.

The packaging cleanroom has recently

been opened for this purpose.

Converteam/Royal Academy of

Engineering Research Chair:

Prof. Phil Mawby occupies a Royal

Academy of Engineering Chair as well

as a Converteam Research Chair. He is

the founder of the Energy Conversion

Research Group at Warwick University

and has worked with several industrial

partners in the automotive and renew-

able energy sectors. He is principal inves-

tigator of several projects funded by the

government and industry.

Research Focus

The research at the Power Electronic

Systems Laboratory (PES) addresses

challenges in power electronics and me-

chatronics that have a fundamental or ge-

neric nature. The considerations are on a

system-oriented basis. Proposed concepts

should allow a translation into future in-

novative industrial products. Motor and

actuator concepts, converter topologies,

power semiconductor technologies, mod-

ulation schemes, control methods, ther-

mal management, and EMI filtering are

seen as coupled issues rather than treated

in a sequential manner. Circuit-oriented

simulation and FEM- and PEEC-based

analysis of the mechanical, electromag-

netic, and thermal behavior are integrated

into the research and design process.

Furthermore, multi-objective optimiza-

tions are performed in order to identify

the Pareto performance limit concerning

efficiency, power density, and costs.

The main areas of research are currently

novel concepts of PWM rectifier sys-

tems with low effects on the mains

highly compact / efficient electromag-

netically integrated DC/DC converter

systems

novel isolated / non-isolated AC/AC

PWM (matrix) converter topologies

ultra high speed drives, magnetic and

hybrid air bearings, bearingless motors

multi-domain / scale modeling, ab-

straction, simulation, and multi-objec-

tive optimization.

In each research area, a comprehensive

experimental verification of the proposed

theoretical concepts is provided that em-

ploys the latest Si and SiC (GaN) power

semiconductor and high performance

digital signal processing technology. The

investigations are currently carried out by

29 Ph.D. students and 4 Postdocs under

full or partial funding by international

industry partners.

Research Areas

The Laboratory for High Power Electronic

Systems (HPE) founded in 2010 at the

ETH Zurich focuses its research on high

power converter systems operating from

low to high voltage levels and power

levels form kW to MW range. The research

is based on a system-oriented view in-

cluding all aspects of power electronics

and related topics. The research results

should enable the development of future

innovative products and/or also enable

power electronic systems to enter new

application areas. The major research

areas are:

Novel topologies & modulation concepts

Advanced passives (E.g. integrated

cooling concepts, integrated EMI

filtering, ultra low loss, low acoustic

noise…)

New control methods

Energy storage systems

Multi-domain modelling:

- Electrical

- Magnetical

- Insulation Design

- Thermal

- EMI

- Reliability

Multi-objective, mission profile

oriented optimisation

The multi-domain modelling of the con-

verter systems enables a comprehensive

optimisation at the system- as well as

at the component-level, for example for

maximal efficiency, ultra high power

density or high reliability. Based on the

mission profile, the system design is

optimally adapted to the requirements

minimising raw material usage and costs.

Also multiple objectives as for example

the system volume and losses can be

considered at the same time. This results

in a Pareto Front or Surface as shown

for example in fig. 1 where different

designs of modular multilevel convert-

ers for medium voltage battery energy

storage systems are compared. Based on

these Pareto Fronts different topologies,

modulations, and also technologies can

be compared.

With the models and the optimisation

also the industrial design process could

be significantly accelerated enabling a

shorter time-to-market.

Laboratory Facilities

For validating the models and the opti-

misation procedures, prototype systems

based on cutting edge technology are

designed and built. An example is given

in fig. 2 showing a prototype of a 22kW

isolated DC-DC converter with efficiency

values exceeding 97.5%. In this converter

also the transformer is magnetically and

thermally optimised for a high efficiency

and a high power density, that could be

achieved by direct cooling of the trans-

former core and winding.

For performing experiments a fully

equipped laboratory with the following

energy sources is available:

0..400V / 250KVA

0..800V / 250KVA

0..25kVAC / 250KVA

0..35kVDC / 250VDC

0..2kVDC / 100kW (bidirectional)

400V arbitrary AC source

Additionally, a faraday cage for shielding

and partial discharge tests as well as dif-

ferent water and air cooling facilities and

a 2t crane are available.
