Abstract : This paper proposes a single switch soft switching isolated converter. The proposed converter is able to offer low cost and high power density in high step up application due to the following features: ZCS turn on and ZVS turn off of switch and ZCS turn off of diodes regardless of voltage and load variation; simple gate driver circuit and low rated lossless snubeer; reduced transformer volume compared to flyback or forward based converters due to low magnetizing current. Experimental results on a 100kHz, 250W prototype are provided to validate the proposed concept.
