Abstract

SiC MOSFETs have become more and more popular in recent years. Apart from its superior performance, attentions should be paid to its driving method. In this paper, an improved transformer driving circuit is proposed which can provide an almost constant negative turn-off voltage within a wide dutycycle range. Both simulation and experimental results are given to verify the effectiveness of this method.
