Solid-State Circuit Breaker (SSCB) with Microsecond Fault Interruption
Ultrafast electronic circuit breaker interrupting DC short-circuit faults in under 5 microseconds without mechanical arc flash.
Project Overview
Replaces slow mechanical breakers in modern DC microgrids. Uses silicon carbide (SiC) MOSFETs/IGBTs and an analog comparator trigger circuit to detect overcurrent conditions and extinguish short-circuit currents in under 5 microseconds, eliminating destructive arc flashes.
