Overflowing with energy

CEFEM TECHNOLOGIES: From southern Ardèche in rural France to the world stage

The company CEFEM was created in 1987 by Georges Fangier, from southern Ardèche in France, to supply components and systems for complex electrical equipment. Over time, the company turned more and more to “Powerful Electronics”, capable of modulating energy for a new generation of applications.

Once expert in energy conversion, in 1999 CEFEM took over the “visible break switches” side of the powerful FERRAZ company. In doing so, the company acquired control over the separation of energy. In 2005 the takeover of Grenoble-based ASB and the setting-up of a production unit in Romania gave CEFEM the status of a group.


A business grows in relation to its knowledge and resources, in parallel with the needs of tomorrow. But also in relation to its values.

CEFEM TECHNOLOGIES has more than 25 years of expertise in the conversion and separation of energy, particularly in powerful energy. It is also a small rural business, despite being out in the wider world. As such, it defends the environmental principles to which it is very attached. Solar energy was an obvious choice.

CEFEM SOLAR SYSTEMS, a fully-owned subsidiary of the group, with a capital of 20 000€, was born in 2009 out of the sum of skills and values of CEFEM TECHNOLOGIES. Our teams never stop developing and testing our Trio-Top range of three-phase inverters.

  • It is a major player in France and in the world in the magnetics and industrial switches market. The average age (35 years old) of the workforce is a key factor in this dynamic atmosphere.
  • It employs 80 people at its 3 production sites and manages a network of 15 distributors on every continent.
