Power loss analysis of two-stage PV-PCS using interleaved soft switching dc-dc converter

This paper presents a grid-connected PV-PCS (Photovoltaic Power Conditioning System) using interleaved, soft switching boost converter for efficiency increment. The numerical analysis about power loss on the proposed PV-PCS is performed. And this analysis is confirmed by the simulation results. It is expected that the analyzed results can be used in the efficiency improvement of PV-PCS.
