Abstract
in this paper, a family of ZVZCS dual switch flyback dc-dc converters were analyzed, which all feature soft-switching, low voltage stresses and good adaptability of wide range input. The main switches and auxiliary switch of these converters realize zero-voltage turning-on (ZVS) and the rectifier diode achieves zero-current turning-off (ZCS). They adopt different auxiliary circuit to realize soft-switching. The strengths and weaknesses of each topology were presented, compared and detailed by application-orientied analysis. Finally an optimal topology will be selected and experiment results obtained from experimental prototypes adopting the recommendation topologies confirm the validity and applicability of the proposed converter.
