A Novel Approach for Current Ripple Reduction in Solar Battery Charging by Multiphase Topology Method

Abstract

This paper shows a novel method for analyzing in multiphase topology method for minimizing ripple currents to larger extents in solar battery charging system commonly used for renewable power generation. DC-DC converters plays a vital role in power conversion and becomes important converter topology that are used in power electronics industry. In low power applications, in case of low watts, single phase converters meet their demands. In such a case, if the systems are larger, their supply current demands continue to increase. For that, power regulators are connected in parallel to high power ratings can be employed. By using power regulators, large ripples in input and output current can be limited. With the use of multiphase topology switch stress can be reduced due to reduced current flow in every phase and by increasing the number of phases as in this way that is here with four phases thus provides additional benefit of current ripple reduction in the input and output. This project discusses multiphase buck converter with increased number of phases connected to a solar battery charger.
