Next Generation Power Electronics
As an application-oriented research insti-
tute, Fraunhofer IISB develops next
generation power electronic systems of
highest power densities, by using latest
technologies like SiC and GaN Wide-Band-
Gap (WBG) Devices.
Battery Monitoring Circuit (UTM4) with certificate of airworthiness from the European Aviation Safety Agency (EASA)
HV „Backbone“ of a (More) Electric Aircraft
60 kW SiC based Drive Inverter Powerstage for High-Speed Drives with volumetric power density of 160 kW / l
Bidirectional 200 kW SiC based DC/DC Converter Powerstage for Automotive Applications with gravimetric power density of 62 kW / kg
Air-cooled 20 kW Boost Converter Powerstage for Fuel Cell Applications, designed for max. Altitude of 15.240 m (50.000 ft.)
Making use of 20 years of experience in
delivering complete prototype systems for
automotive applications, IISB is able to
provide technologies for the complete High
Voltage “Backbone” of a More/All Electric
Aircraft, ranging from non-/isolating
DC/DC converters and AC/DC motor/grid
inverters to complete battery systems and
DC grid control technologies.
Project Examples
Recent project examples illustrate technical
possibilities of latest IISB developments at a
glance. The novel WBG semiconductors
with their reduced losses and advanced
low-inductive system designs enable
power-densities far beyond state-of-the-
art, paving the way towards More and All
Electric Aircrafts.
More and detailed information will be
given upon request, and starting a
technical discussion about your specific
application is highly appreciated.
Collaboration
IISB is your research partner in power
electronics for avionic applications, either
in collaboration in public funded research
projects, or in bilateral developments under
complete NDA.
