低压直流微电网总线故障中断时瞬态过电压抑制的固态断路器缓冲电路设计

Under a short-circuit fault in low-voltage dc microgrid, solid-state circuit breaker (SSCB) assumes the responsibility of the quick and effective isolation of the faulted area, while its own safety and reliability depends on the overvoltage suppression ability of its snubber. For SSCB snubber design, however, traditional method suited for converter switch snubber cannot be directly applied, becaus...
