Solid-state circuit breakers in DC distribution networks

, 2020
The design and development of two direct current (DC) solid-state circuit breakers (SSCBs) for use in low voltage DC distribution systems were examined. Both SSCBs utilized the isolated-gate bipolar transistor (IGBT) and were developed for low current applications of under 20 A. The approach was documented to show the advancement of IGBT technology and
