Abstract
This paper describes the evolution of a power electronics class at Master level (second year), to comply with the new trends of this science. Indeed, the switching speed of power semiconductor devices –especially wide bandgap devices– is continually increasing and, the knowledge and comprehension of switching mechanisms is absolutely necessary to design power converters. Apart from theoretical lectures, several lab works have been specifically developed, to use these devices at their rated operating point. Five different themes are studied: device characterization (bare dies), switching waveforms, losses characterization, thermal design, ElectroMagnetic Compatibility and magnetics design.
