Abstract : A modified high voltage gain dc-dc converter with improved efficiency has been proposed in this article for PV based applications. In the proposed methodology, converter is integrated with a switched capacitor and a switched coupled inductor. This converter topology provides high voltage gain with fewer components. The efficient power conversion has been achieved with low switching voltage across the semiconductor devices. The working principle and analysis of the converter is described in this article. The converter design is made for 250-W power rating system. Performance of the proposed converter is analysed and validated the efficiency at various loading conditions.
