Know howContinuous investment in research and development

With continuous investment in research and development, FRIEM is leader in Diode, Thyristor or IGBT type High Power Converters, applying the most advanced technologies and electronics.

Our StoryFounded in 1950 to design and manufacture High Power Converters, FRIEM continued to develop its know-how in energy conversion for industrial and traction applications.

In 1956 FRIEM produced and installed its first 50kA Rectifier Unit for application in Chlor-Alkali industry.At the absolute forefront in technology, in the early 60’s FRIEM was able to manufacture units rated up to 110kA and to design the first high current Thyristor Rectifier.

Service continuity required by the Electrochemical Industry oriented FRIEM’s design towards absolutereliability; quality, safety, latest international standards have always been the base for the design anddevelopment of our Equipment.

In the early 70’s when FRIEM started the production of Rectifier Units for traction application. With the support of its Partners, FRIEM provides complete Substations Systems with all the main equipment and services.

In 1984 FRIEM was able to design and start-up its first Power Supply for a PolySilicon CVD Reactor. Nowadays FRIEM has hundreds of units in service all over the World supplying all the different types of CVD Reactors.

In 2009 FRIEM started the production of the RECon Line, a complete line of Inverters for the renewable energies (Photovoltaic Plants and Wind Turbines), becoming one of the main manufacturer in Italy and in the World.

In 2015 has been introduced the RECon HV Line, the 1,500V DC Inverter for the next generation of PV Solar plants.

The new requirements of energy efficiency and cost reduction drove FRIEM to present in 2015 the RECon Line, an IGBT Inverter that allows to recover the energy generated by the train during the braking phase (usually in Subway or Tramway).

Founded in 1962 for the production of LV and MV disconnector switches, COET operates nowadays in two main sectors, Industry and Traction, being one of the leading companies for the supply of equipment for Traction Substations. COET joined FRIEM Group in 2008: a new experienced management with the clear and ambitious target to grow the company in the direct export - mainly in Traction field - reaching worldwide the same leader position held in Italy for decades.

AKTIF Elektroteknik The company was established to manufacture Switchgears and Kiosks in 1981. In 2008 merged to Aktif Group as Aktif Elektroteknik (AET) and then became an international co. after significant participation of FRIEM in 2009. AET operates with its 30 years of manufacturing experience, modernized machinery line, ever increasing know-how, experienced Turkish and Italian R&D teams, quality products type tested by the leading accredited European laboratories and the vision of new ideas to meet with the future expectations.

In 2012 FRIEM started to broaden its own production founding FRIEM Conversores Ltd based in San Paolo (Brazil) and then, in 2014, FRIEM South Africa based in Cape Town. As a result, customers can rely on the quality and performance of FRIEM’s products, with the advantage of a local production and after-sales assistance. To address these important requirements in the Indian market, FRIEM signed in 2014 a License agreement with L&T - C&A (Larsen and Toubro Control and Automation) for the local production and distribution of the RECon Line Inverters in India.This represents for FRIEM a further step towards its continuously growing international expansion and an outstanding accomplishment in the field of Industrial and Renewable energy Inverters.

The strategy of making FRIEM’s local presence stronger also counts nowadays with offices and representatives in more than 20 Countries all over the World.

Maximum Power Point TrackingThe Characteristics of photovoltaic panels are not stable, in fact they vary in function of weather conditions and solar irradiation.

The purpose of the MPPT System is to follow the maximum power point for any photovoltaic module.Analyzing the V-P solar panel characteristic, it can be noticed that, when environmental conditions change(partial shading of the panels), there exists different absolute and relative maximum power points.

The MPPT controls the voltage, current and power of the photovoltaic field and generates the Reference Current for the Current Regulator of the Inverter to achieve the greatest possible power harvest.The MPPT algorithm sample the output of the photovoltaic panel, to obtain the Maximum Power for any given environmental condition.The calculated voltage at which the photovoltaic panel should work is based on the voltage measurement of the panel and from the supplied Power.

The two most common methods to execute the MPPT algorithm are: - Incremental Conductance (IncCon).- Perturb and Observe (P&O).

The RECon Line Inverters use both algorithms.

In the new Photovoltaic systems, off-grid and grid-tied, the inverter must be coordinated with other source of energy (Diesel or Gas Generator, etc.).For this purpose FRIEM has developed the GC and OGS, flexible control systems that allows the Solar PV energy to be integrated and maximized according to the requirements of the whole plant.

Our systems have been developed to allow the RECon Line Inverters to work in parallel with one or more emergency generators, batteries and etc. in any condition of the grid. It is particularly efficient in those countries where power outages are very frequent and allows not only to save generator fuel and maintenance costs but also to have a higher power continuity and a better exploitation of the PV plant.

The complete functionalities (load power measurement, acquisition of the generator and main switches statuses, master communication controller to the RECon Line Inverters) are realized in a small box, suitable for outdoor installation, equipped with a touch display for configuration, diagnostic and measures.
