Introduction
The electrical and thermal performances of switching converters are strongly influenced by
the behavior of the switching devices. Modern power devices design requires a trade-off in
terms of forward voltage drop, breakdown voltage and switching speed. In AC-DC
converters such as PFC circuits, efficiency is strongly related to the switch performances
and the diode recovery behavior (please refer to 1 in Bibliography on page 18). In the past
the benefits of th
