Work experience
DESIGN AND STUDY OF A 6KVA INVERTER BASED ON SIC COMPONENTS AND INTEGRATED INTO AN ASYNCHRONOUS MOTOR

ANGOULÊME
Sillac siège

Mission and objectives

Energy efficiency is nowadays an increasingly important criterion in the design
of industrial electrical energy conversion chains. Large gap semiconductors (SiC
and GaN) present a very interesting solution for improving the efficiency and
power density of static converters.
In this context, we offer a four to six month internship on the design of a 6kVA
three-phase inverter based on discrete SiC components, integrated in an
asynchronous machine. The student trainee will be integrated into a
multidisciplinary R&D team and will participate in the theoretical study as well as
the experimental validation of the results

- Establish the state of the art of WBG semiconductors
- Sizing of the inverter board taking into account the constraints related to the
switching mesh (overvoltages, Miller effect, etc.)
- Consideration of thermal stress in the design of the converter- Design
validation with simulations and experimental tests
