Abstract
A solid-state circuit breaker includes an input, an output, a solid-state switch, a protection circuit, and a control circuit. The input is configured to connect to a source. The output is configured to couple with at least a first load via a first electromechanical breaker and a second load via a second electromechanical breaker. The solid-state switch selectively couples the input with the output. The protection circuit is configured to open the solid-state switch in response to the fault current exceeding an overcurrent protection threshold. The control circuit is configured to determine whether an electrical fault is present, and in response to determining that the fault is present, operate the solid-state switch in a pulse conduction mode during the fault to current-limit the fault current to less than the overcurrent protection threshold and enable one of the first and second electromechanical breakers to trip and isolate the fault.
