DC-DC converter is an electronic device that converts direct current (DC) from one voltage level to another. It is an electrical power conversion system. The conversion levels vary from low to very high power and for its applications. A control strategy for power flow management of Grid connected PV-Wind-Battery Based Multi-input transformer coupled Bi-directional DC-DC converter is presented in this paper. To harness power from wind a transformer coupled boost half bridge converter is used, while to harness power PV along with battery charging/discharging control bidirectional buck-boost converter is used. For feeding ac loads and interaction with stages radiations a single phase full bridge bidirectional converter is used. The proposed system aims to meet out the load demand, manage the power flow from various sources, injection of surplus power into the grid and charging the battery from grid as and when required. Simulation results obtained using MATLAB Simulink show the performance characteristics of the proposed control strategy for power flow management under different modes of operation. The simulation result states that the system requires less number of components for power conversion, and reduced losses compared to existing grid-connected Hybrid systems. This improves the system efficiency and reliability.
