Mission and objectives

Energy efficiency is nowadays an increasingly
important criterion ,important in the design of
electrical energy conversion chains industrial.
Wide-gap semiconductors (SiC and GaN) exhibit a
very interesting solution for improving the yield
and density of power of static converters.
In this context, we offer an internship of at least
six months on the design of a switching power
supply based on discrete SiC components.
This power supply must be integrated into high power variable speed drives
with harsh environmental conditions.

-Choose the power supply architecture
-Sizing of the various power supply components (mosfet
SiC, transformer, dissipator,…)
- take Consideration of thermal stress in the design of
the SMPS
-validation of the design with simulations
and experimental tests
