This thesis is aimed to study a bidirectional transfer battery charging system with gain adjustment capability. When the power generation is sufficient, the excessive power can be stored in the battery, and when the power generation is insufficient, the battery would deliver energy back to the grid. To meet this application requirement, this study designs a bidirectional power transfer converter with constant voltage and constant current output characteristics. Both the primary and secondary sides of the converter adopt inverter architectures with active switches, integrating CLLC and LCL resonant tank architectures. This allows for switchable constant voltage (CV) and constant current (CC) output modes, enhancing charging speed, preventing battery overcharging, and supporting a wide range of voltage gain adjustment. In addition, a non-isolated bidirectional converter is incorporated to regulate the system gain and accommodate the charging requirements of batteries with different specifications. The control system is implemented using a microcontroller to manage power switch control. With the aid of voltage and current feedback detection circuits, the system realizes high-frequency switching, mode transition, and gain modulation. Experimental verification under various load conditions confirms the feasibility and performance of the proposed system, demonstrating its applicability to energy storage systems and providing a valuable reference for electric vehicle development.
