常开型宽禁带晶体管栅极驱动的超快自供电电路

Normally on wide-bandgap (WBG) devices switch faster and have lower power loss compared to similarly rated normally off devices. However, their application in voltage-fed power electronic converters is limited due to the risk of the dc-link short-circuit condition. Several techniques are proposed in the literature to address this problem. However, some drawbacks exist, first, the use of several ad...
