A novel DC hybrid solid state based circuit breaker on IGBT was presented by analyzing and comparing advantages and disadvantages of solid state circuit breakers. Compared with the experimental results of the mechanical circuit breaker, the novel solid state circuit breaker provided a faster acting arcless mechanism with high current limitation. Circuit parameters which affect commutation time were also studied briefly.
