Abstract

In DC power supply system, a fast response circuit breaker is required. Semiconductor DC circuit breaker is an important key technology in DC power supply system. This paper considers the operating characteristics of Silicon Carbide-Static Induction Transistor (SiC-SIT) based DC circuit breaker in DC power supply system when grounding fault occurs. The operating mechanism of grounding fault case is explained compared with short fault case.
