Abstract: Now days many countries are concentrating on electricity power generation from renewable energy sources (RESs) as it is pollution free. The RESs are wind turbine, photo voltaic cells, tidal etc. Photo Voltaic (PV) power generation system is more attractive due to its advantages among all the RESs. Solar energy is extracted with the help of PV panels and power electronics converter. It is then fed to an inverter that produces an AC power. A dual output Single Ended Primary Inductance Converter (SEPIC) is proposed for DC to DC energy conversion in PV system. It charges two batteries, which in turn feeds a new modified cascaded multi level inverter. The proposed system is a fusion of dual output SEPIC converter and Multi Level Inverter (MLI). It can be used for power generation in remote areas, large residential buildings and standalone systems. The circuit simulation is carried out in MATLAB/Simulink.
