A DC-DC multi-output SEPIC converter for suburban power application

Abstract

Non conventional sources of energy are those which are depleting day by day. Solar energy which is abundant in India has gained more importance hence. The energy produced by the sun, is harnessed with the help of PV panels and injected to converters and rectifiers. It is subsequently fed to an inverter that produces an AC power. In this paper, a PV panel fed modified dual output SEPIC converter is proposed. Dual outputs obtained from the modified multi output SEPIC converter is used to charge two batteries which in turn are fed to the cascaded multilevel DC/AC inverter. The simulation analysis of the system proves that it is well suited for both resistive and inductive loads; hence it is proposed for driving a motor load in rural areas agricultural applications. This system can be deployed in areas where grid connection is not possible such as in isolated or rural areas.
