Abstract

This paper presents a modified two-stage sepic based five-level inverter for photovoltaic applications. The proposed configuration is built with a frond-end sepic converter cascaded with full bridge inverter through a high-frequency transformer and auxiliary circuit. The merits of the proposed configuration are high boost output voltage level, modularity, reduced device parts, and better quality of supply. In this paper, detailed construction and operation of the proposed two-stage configuration is presented. In order to validate the concept, simulation work is carried out through Matlab software and their results are presented.
