چکیده

This paper introduces a three-port DC-DC converter (TPC) designed for enhanced voltage-gain applications. The TPC features two input ports, including a bidirectional port for charging and discharging a battery. It incorporates a switched inductor to achieve higher voltage gains. The converter is capable of operating in four modes, one of which is a battery-alone mode. Compared to existing topologies, the proposed design significantly reduces the ripple of the input current and ensures a common ground connection between the input and output ports. This configuration makes the TPC particularly suitable for renewable energy applications. The functionality and effectiveness of the proposed converter are validated through an experimental prototype with a power of around 400 W. The experiments verified the dynamic performance of the converter during load step changes and mode transitions.
