Abstract
A circuit breaker network includes a solid-state circuit breaker (SSCB), one or more circuit breakers, and a current limiting control circuit of the SSCB. The current limiting control circuit is programmed to determine a first time period for keeping the SSCB in an on state, determine a second time period for keeping the SSCB in an off state, and switch, cyclically, the SSCB to the off state for the second time period and then to the on state for the first time period to control the fault current within a predetermined band-to-band range that is below the first current threshold and above the second current threshold for a fault clearance duration.
