In this paper the performance of Si, SiC and GaN MOSFETs is compared for a low power (5W) and high voltage (800V) two-phased quasi resonant flyback converter. The first step is the selection of proper ...

Because SiC MOSFET-based zero-voltage switching (ZVS) power converter circuits provide high-speed switching, high power density and high efficiency can be achieved. However, an undesired negative ...
