Certain investigations on performance improvement of transformerless grid connected photovoltaic power conversion systems

Abstract

The power generation from renewable energy sources is popular newlinedue to the increasing energy demands depleting fossil fuels and enforcement newlineof carbon emission reduction There are several renewable energy sources newlineavailable like wind solar tidal geothermal biogas fuel cell etc out of newlinewhich solar energy is the most promising and reliable As such it is available newlinefree of cost throughout the year It is an environmental friendly energy source newlinethat can be used to generate electric power through photovoltaic effect The newlineperformance and efficiency of medium and large scale Photovoltaic PV newlineplant mainly depends on power conversion process through power electronic newlineconverter interfaced between PV plant and the distribution grid or load The newlinepower conversion system used in the existing Solar PV SPV plant involves newlinehigh cost and reduced efficiency due to more than one power conversion newlinestage newline newline
