Introduction

"ElectroPower ElectroNics" (ENPU) is a central theme of the GeePs laboratory because it is at a crossroads. Every electrical system needs to be powered by a battery or the mains. Therefore, an energy management component is involved, for embedded systems to improve the integration of new energy sources or to limit the consumption of devices. Thus, many power supplies exist, and with the increase in energy consumption, always more power, less volume, more reliability. This theme of the laboratory was the strength of Supélec and LGEP with many innovations in the past. One might then believe that everything has already been discovered in the past, so much so that power electronics has a historical dimension, but new constraints are appearing, with new components to be integrated to improve performance. Scientific and technical progress is essential to limit energy losses and major advances are emerging to lay the foundations for tomorrow's world. The ENPU theme has forged a name for itself through the architecture and production of converters, through the development of magnetic components, and is opening up to the study of the reliability of large gap semiconductors.

Numerous theses are thus initiated through the following axes:

  • Axis 1:
    • Integration of power electronics within a system
    • IntégraIntegration of GaN/SiC components for battery chargers, for the automotive, aeronautic and industrial industries.
    • Architecture of converters to improve efficiency and volume, taking into account the specificities of a specification
    • Conception de nouveaux composants magnétiques et d’outils de mesures
  • Axis 2: New multi-cellular conversion architectures
  • Axis3: Reliability analysis of large gap power semiconductor components
