High Step-up Modified SEPIC Converter for Renewable Applications

Abstract

A high step-up Dc- Dc converter based on  the Modified SEPIC converter is present in this paper. This topology is the combination of a classical boost converter and a conventional SEPIC converter. The Modified SEPIC converter used for low input voltage and high output voltage applications. The theorectical analysis shows that it is suitable for the applications such as a renewable power sources with low DC output voltage The operational analysis and the design is done for the 100W power output of the modified converter. The solution is proved by MATLAB/SIMULINK.
