N2 - In recent years, photovoltaic systems with energy storage components have been used more and more frequently globally, but the prices and costs have remained high. Because these photovoltaic systems often require multiple complex converters to control each port individually. Compared with the traditional multi-port converter, the multi-port integrated converter has the advantages of simplifying the system structure, improving the operation reliability and reducing the number of components. This study offers a non-isolated three-port converter based on a four-switch H-bridge converter that achieves one stage of direct power conversion between three ports. Pulse Width Modulation (PWM) and Phase Shift Modulation (PSM) create flexible power adjustment and balancing between the three ports to control decoupling. This integration reduces the number of switches and achieves a reduction in circuit volume and a simplification of the topology. A detailed analysis is carried out, and then the topology waveform and the dynamic closed-loop control between the three ports are verified by simulation.
