Abstract:
This paper presents a test concept for a dynamic gate stress test under high drain-source voltage and high acceleration via switching frequency (HV-GSS). Gate-switching stress tests with and without drain voltage (HV-GSS and GSS) were conducted using SiC trench MOSFETs in order to determine the in-fluence of high drain-source voltage on gate reliability in terms of gate-switching instability.
