TLDR
In this paper, a soft switched single switch isolated dc-dc conveys is proposed in which the switch works on zero current switching (zcs) during turn on and zero voltage switching during turn off.Abstract:
A soft switched single switch isolated dc-dc conveys proposed in this paper. This converter works on the principle of zero current switching (zcs) and zero voltage switching (zvs). The circuit comprises lossless snubber with low rating. The switch works on zcs during turn on and zvs during turnoff. The diodes are based on zcs turn on and turnoff conditions. This paper presents the concept of soft switching and its applications to dc-dc converter. The losses due to soft switching and hard switching are compared.read more
