Design of a snubber circuit for low voltage DC solid‐state circuit breakers [PDF]
IET Power Electronics, 2021 Abstract Solid‐state circuit breakers (SSCBs) are designed to interrupt fault currents typically several orders faster than its electromechanical counterparts. However, such an ultrafast switching operation would produce a dangerous overvoltage which might cause damages to SSCBs and other circuit elements in the system.

Solid-State Circuit Breaker Component Simulation
IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021 The landscape of direct current (DC) solid-state circuit breakers (SSCBs) is growing and so too is the choice of primary components. There now exists a wide range of devices capable of withstanding voltage levels conducive to electrical transmission; though steady state efficiency of these devices remains a concern.
