Principles and carrying out of power semiconductor components - 5EUS5PMS

Goal(s)

The design of a power electronics converter is not easy. In fact, lots of physical constraints have to be taken into account to use power semiconductor devices in optimal conditions.
In this teaching module, we present the physical basis of semiconductor devices. Then we study how to drive, to package, to cool and to integrate them in a switching cell (routing rules).
EMI issues are also outlined in order to understand how to introduce a converter in a more complex system.
