基于串联SiC MOSFET的中压双有源桥变换器分析与设计

In this article, a series-connected SiC MOSFETs-based medium voltage (MV) dual active bridge (DAB) converter featuring a low voltage difference among devices and high efficiency is proposed. In the developed DAB converter, the zero voltage switching-on characteristic is used to redesign the voltage balancing snubber circuits of the series-connected SiC MOSFETs. The snubber resistance is greatly re...
