Abstract

The embodiment of the present disclosure relates to a solid-state circuit breaker and a method for controlling reclosing of the solid-state circuit breaker. The solid-state circuit breaker includes: a power electronic switch located in a main loop; an instantaneous trip protection circuit configured to output a first signal for controlling the power electronic switch based on a current in the main loop; a pulse width modulation (PWM) circuit configured to charge a load in a PWM current-limiting mode based on the current of the main loop and output a second signal for controlling the power electronic switch; and a gating circuit connected to the instantaneous trip protection circuit, the PWM circuit and the power electronic switch, and configured to selectively connect the instantaneous trip protection circuit or the PWM circuit with the main loop.
