Abstract: In this paper a Dual Input DC/DC Converter (DIC) is proposed for Hybridization of renewable and storage energy sources. The converter provides a regulated voltage at the load. The two input sources to the converter may include Photo Voltaic (PV) cell, Fuel cell, Wind source etc. Converter may beoperated in Buck, Boost or Buck-Boost modes. Based on the operating conditions power is delivered to load from thetwo sources either simultaneously or individually.The complete DIC hassmaller size hence overall cost is reduced due to the less number of components. Using MATLAB/Simulink software proposed converter is simulated and performance of the converter is analysed.

Keywords: Dual input DC/DC converter, PV cell, Battery, MATLAB/Simulink.
