Since 1950 FRIEM is leader in IGBT, Thyristor or Diode type Power Converters, applying the most advanced technologies and electronics.

Founded in 1950 to design and manufacture High Power Converters, FRIEM continued to develop its know-how in energy conversion for Industrial, Light and Heavy Electric Mobility, Renewable Energies, Energy Storage and Management applications.

FRIEM is a reference for the electric energy conversion and has been a preferred technological partner in several pioneeringmarkets, sustaining its customer’s operations and results.

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 Rectfier. Service continuity required by the Electrochemical Industry oriented FRIEM’s design towards absolute reliability and availability: quality, safety, latest international standards have always been the base for the design and development of our Equipment.

This experience and know-how were applied in the early 70’s when FRIEM started the production of Rectifier Units for heavy electric 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 supporting the PolySilicon production Industry supplying the Solar Photovoltaic market.

In 2009 FRIEM started the production of the RECon Line, a complete line of Inverters for the Renewable Energies, becoming one of the main manufacturer in Italy and in the World.

To support the growing requirements of Energy Storage and Energy Management, FRIEM developed the HYCon Line, Bi-directional Inverters and DC/DC Converters integrating different energy sources with batteries (fitting different technologies) and the relevant Control System. The first Hybrid Systems started operation in 2017 and today FRIEM has already references in Mini-Grid, Recharging Stations and Grid Ancillary Services.
In order to serve our customers with a wider range of products and solutions, FRIEM has started partnerships and investments with expert Electrotechnical Companies. This strategy gives FRIEM an even stronger Local presence, with offices, workshops and representatives in more than 20 Countries all over the World.

In its 11000 m2 facilities nowadays FRIEM designs, manufactures and delivers all over the World:

AC/DC High Power Rectifiers
