Passive circuit configurations for snubber energy recovery in power converters using hard-switched devices

, 1994
The use of snubber circuits on switches in power switching electronic equipment increases circuit efficiency, allowing increased switching frequency and smaller volume due to decreased losses that must be dissipated.

Gate driver, snubber and circuit design considerations for fast‐switching series‐connected SiC MOSFETs

IET Power Electronics
Series connection of Silicon Carbide (SiC) Metal‐Oxide‐Semiconductor Field‐Effect Transistors (MOSFETs) is an interesting solution to design switches for voltages that are not yet commercially available or limited for single‐die devices.
