Abstract
This paper considers the malfunction mechanism of semiconductor circuit breaker in high voltage DC power supply system (HVDC). In HVDC system, the fast response breaker is required. Semiconductor circuit breaker is paid attention as one of the key technology in HVDC. However, in some condition, the semiconductor circuit is malfunctioned. When malfunction is happened, unexpected large current is flown to the other normal line. In this paper, the generation mechanism of unexpected-current is described.
