Passive Lossless Snubber for PFC AC–DC Converters
Electrica, 2020 In this study, an improved passive lossless snubber cell for the non-isolated pulse-width modulation direct-current (DC)–DC converter family is proposed. The proposed snubber cell provides soft switching for all semiconductor power devices in the converter under wide-input voltage–current and output load ranges. Detailed theoretical analysis is carried

Lossless passive snubber for half bridge interleaved flyback converter
IET Power Electronics, 2014 Discontinues output current of regular flyback converter will cause several problems such as large volume of output capacitor and also high output voltage noise. Interleaved structure can reduce output current ripple and process more power compared with single‐phase flyback converter.

Passive lossless snubbers for DC/DC converters [PDF]
APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition, 1998 Passive lossless snubbers are proposed to improve the turn-on and turn-off transients of the MOSFETs in PWM DC/DC power converters. Switching losses and EMI noises are reduced by restricting the di/dt of the reverse recovery current and the dv/dt of the drain-source voltage. The MOSFET operates at ZVS turn-off and near ZCS turn-on.
