Research and Design of 1700V 250A SiC MOSFET Driver

In this paper, RoHM BSM250D17P2E004 as the driving object, the driver and protection circuit of 1700V and 250A SiC MOSFET are studied and designed. The minimum pulse width suppression and anti-crosstalk drive circuit, desaturation detection and active clamp protection circuit of SiC MOSFET are studied emphatically. The reliability of the driving circuit and the validity of the protection circuit are verified by experiments.
