Abstract

The renewable energy sources, such as Solar Photovoltaic (SPV) systems, when working alone, are regarded greatly insufficient and suffers from poor reliability, sustainability and substantiality in terms of stability in energy density and efficiency of the supply system. The present work focuses on the designing of power-electronics-based-converter-system to integrate and harvest energy from two different sources working with different voltage–current characteristics. As a result, the work listed in this paper involves designing of a double input DC–DC converter for integrating an SPV system with a storage battery system. The proposed converter bears the advantage of loading the hybridized sources either discreetly or concurrently with the provision of combining the sources in series or in parallel as required by the load. The converter topology also has the capability of power flow in either direction with the feature of being operated in buck, boost and buck-boost modes. A controller is designed which utilizes Pulse Width Modulation (PWM) technique for generation of pulses for power electronic switches. The extensive simulation study is performed in MATLAB / Simulink environment.
