Design of a snubber circuit for low voltage DC solid‐state circuit breakers
IET Power Electronics, Volume 14, Issue 6, Page 1111-1120, 6 May 2021., 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.

IET Generation, Transmission &Distribution, Volume 15, Issue 1, Page 45-55, January 2021., 2021 Abstract The high‐surety power supply systems are gaining great attention to enhance the reliability of uninterruptable power supplies. A high‐resistance fault along a high‐surety power supply feeder results in a low fault current, making the conventional high‐surety power supply protection strategy ineffective.
