Abstract: Here in this paper it mainly deals with boost converter. We know that the boost converter is mainly used for voltage step -up. Here mainly two-input hybrid boost SEPIC dc-dc converter is proposed in this paper. Actually the paper gives an integration of boost converter with the SEPIC converter. The proposed converter is capable of giving large duty ratios. Here 12/24V to 75V with output power capacity of 200W.
Keywords: Boost converter, Hybrid boost converter, Two input dc-dc converter.
