基于关断米勒平台电压的SiC MOSFET在线结温监测方法

Online junction temperature monitoring of SiC mosfet based on turn-off Miller plateau voltage (VMP,off) has been explored in this article. As the junction temperature rises, VMP,off experiences a decline while extending its duration, thereby enhancing the precision of sampling VMP,off with a diminutive turn-off resistance (Rg,off). A novel extraction approach for VMP,off is introduced, involving t...
