Abstract
A hybrid circuit breaker includes a semiconductor circuit breaker, connected between a first output end of a converter of a power supply or a source branch and a first end of a damping module; a first mechanical circuit breaker, connected in parallel to the semiconductor circuit breaker, an energy absorber, connected in parallel to the semiconductor circuit breaker, and a controller coupled to the semiconductor circuit breaker and the first mechanical circuit breaker, and when a current flowing through the converter is greater than a safe current, the controller is configured to control the first mechanical circuit breaker to be disconnected, and control the semiconductor circuit breaker to be closed.
