High Frequency Transformer Based Improved Gamma ZSI with Lossless Snubber

open access: yesIECON 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 ...

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

open access: yesIET 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.
