Abstract
A DC solid-state circuit breaker is provided with fail-safe redundancy. The DC solid-state circuit breaker comprises an air gap disposed in series to first and second power electronics switching modules. The DC solid-state circuit breaker further comprises a sensing and control circuit configured to realize designed functions. The DC solid-state circuit breaker further comprises first and second overvoltage protection devices connected in series for overvoltage or surge protection for the sensing and control circuit such that both the first and second overvoltage protection devices have threshold voltages higher than a system voltage. The DC solid-state circuit breaker further comprises a load side overvoltage protection device provided for overvoltage protection after switching OFF.
