High Frequency Transformer Based Improved Gamma ZSI with Lossless Snubber
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 ...

Half‐bridge flyback converter with lossless passive snubber and interleaved technique
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.
