Abstract :
In this paper, a novel active snubber cell which is used in a boost type DC-DC converter is proposed. The proposed snubber cell provides zero voltage transition (ZVT) and zero current transition (ZCT) for the main switch of the converter. All of the semiconductor devices turn on and off under soft switching. The converter has a simple structure and minimum number of components. Steady state analysis of the converter is presented, and theoretical analysis is verified by a prototype of a 1 kW and 100 kHz boost converter
