M. Kim, D. Yang and S. Choi, "A Fully Soft-Switched Single Switch Isolated DC-DC Converter", IEEE Applied Power Electronics Conference, pp.1106-1111, Mar. 2014, Texas, USA
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.
