一种具有鲁棒分断能力和高效率的新型固态断路器

A novel solid-state circuit breaker with robust breaking capability and high efficiency is proposed for low-voltage dc microgrid protection. First, the proposed solid-state circuit breaker (SSCB) makes the commutation current flow inside the breaker. Thus, it can interrupt faults without reflecting current surges to sources or loads and effectively protect them. Second, by introducing the voltage ...
