초록

This paper proposed a novel fault detection circuit comparing the gate voltage of IGBT. The proposed scheme is operated to protect IGBT under short-circuit faults such as hard switch-fault (HSF). The proposed circuit consists of two parts. One is the difference generator which generates a difference between a gate voltage and an input voltage. The other is the short-circuit fault detector using a charged voltage of capacitor for short-circuit fault detection. The feasibility of the proposed short-circuit detecting scheme is verified by simulation results.
