Cefem Power is the historic branch of the group. Created in 1987 in the Southern region of France by Georges Fangier. Cefem began by developing expertise in low frequency inductive components. Gradually, the business unit integrated more and more magnetic components intended for power electronics, capable of modulating energy for next-generation applications, and this is what led to its rapid expansion.
Over time, Cefem Power's objective became clearer and the goal was to become one of the European leader in passive components for power electronics through 6 production sites : Saint Michel de Boulogne, Grenoble, Lyon, Châteauroux and Romania.
CEFEM is founded in the Ardèche region of France
Acquisition of ASB (Atelier Spécial Bobinage), a production unit in Grenoble making toric components.
Creation of Cefem Romania, a production unit in Dumbraveni. This plant was intended to serve customers with low added value products in large scale series.
Acquisition of SCR, a company manufacturing film capacitors since 1961 in Châteauroux in the center of France. SCR capacitors are now marketed under the name "Cefem Power".
Acquistion of Transrail Boige and Vignal. The consistent progress continues with the acquisition of a company recognised for its expertise in more powerful magnetic components, in particular in the rail market.
Medium Frequency Specialist
CEFEM POWER has, in the past, provided low frequency magnetic components (50Hz). However, for more than a decade, CEFEM POWER has focused on the development and manufacturing of medium frequency passive elements (>5kHz).
We believe that medium frequency will replace the reference frequency although it remains predominant in certain applications.
In response to different needs, we use a range of materials :
Ferrite, Iron powder, Amorphous, Litz wires, Braided copper wires...
We also have qualified engineers specialised in the design of medium frequency magnetic components.
Thanks to our subsidiaries based in the South-East of France, we can supply medium frequency transformers and inductors up to 500kW.
Our partners have trusted us for several years in the study, design and production of magnetic elements, why not you ?
Si vous voulez avez un problématique et/ou une question sur les éléments passifs (transformateurs et inductances) avec une plage de fréquence de 5kHz à 500kHz, n’hésitez pas à nous joindre.
If you have a problem and/or a question about passive elements (transformers and inductors) with a frequency range between 5kHz and 500kHz, do not hesitate to contact us.
