ANALYSIS AND IMPLEMENTATION OF HIGH GAIN TWO INPUT BOOST CONVERTER FOR RENEWABLE ENERGY SYSTEM

Abstract

This paper proposes a voltage multiplier cell based two input Boost converter. By providing continuous input current with lower input current stress, high voltage gain, and lower switching voltage stress, the proposed converter is suitable to interface low voltage level sources like fuel cell, battery and solar cell. The proposed converter can draw current from two input sources or a single source continuously. The operation principle and selection of components are provided. A 115 W prototype of the proposed converter with Vin1=12V, Vin2=12V has been built to validate the analysis of the proposed converter.
