A Bi-Directional DC-DC converter drive with PI and Fuzzy Logic Controller is present in this paper .Speed output is used as feedback for significantly improving the dynamic performance of DC-DC Converter drive. Bidirectional DC-DC converters allow transfer of power between two dc sources, in either direction. Due to their ability to reverse the direction of flow of power, they are being increasingly used in many applications such as battery charger/dischargers, dc uninterruptible power supplies, electrical vehicle motor drives, aerospace power systems, telecom power supplies, etc. In step-up mode, the primary and secondary windings of the coupled inductor are operated in parallel charge and series discharge to achieve high step-up voltage gain. A Simulink based model is developed and the simulation results for the proposed model are obtained by using MAT LAB.
