Increase in the cost, world global energy consumption and use of conventional energy sources, Photo-voltaic installations are being increasingly used in distributed power generation and stand alone systems. They are Clean and green energy sources. But the output of the solar PV is very small hence high gain DC-DC converters are required and to obtain maximum power MPPT techniques are used. In this paper a high gain coupled inductor based DC-DC converter and a Hybrid bidirectional converter with low component counts are presented which is used for battery charging and discharging in the absence of solar. Simulation results obtained using MATLAB/Simulink show the performance of the converter control strategy for power flow management under various modes of operation. The effectiveness of the topology of both converters are validated through detailed experimental studies, to demonstrate the capability of the system operation in different modes.
