一种基于耦合电感的SiC MOSFET串联主动均压方法

The series connection of SiC MOSFETs is an attractive way to expand the voltage of SiC devices. However, the voltage imbalance is among the most critical challenges to overcome. In this letter, an active voltage balancing method suitable for two devices connected in series is proposed. Specifically, a multiwinding coupling inductor with low number of turns is applied to achieve voltage deviation s...
