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

Half‐bridge flyback converter with lossless passive snubber and interleaved technique
IET Power Electronics, 2018 Hard‐switching flyback converters are widely used in the low power application but suffer from high electromagnetic emissions, current ripples, and low efficiency. To overcome these problems, a half‐bridge flyback converter with a new lossless passive snubber is proposed using an interleaved structure.

High Frequency Transformer Based Improved Gamma ZSI with Lossless Snubber
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018 This paper presents an improved single phase high frequency isolated gamma Z-source inverter (ZSI) with clamped diode. It consists of a high frequency transformer between the inverter bridge and load. A lossless snubber diode is employed to provide voltage clamping across the DC-link voltage to overcome the voltage overshoots caused by the leakage and ...
