چکیده :

This paper presents a double-input, single-output converter topology and its control scheme. The proposed converter consists of two parallel DC-DC boost converters and a full-bridge converter. In this hybrid system, the photovoltaic (PV) panel is controlled using the incremental conductance (IC) maximum power point tracking (MPPT) algorithm, while the battery is managed through a control method that regulates the state of charge (SOC), supports energy balancing, and stabilizes the DC link voltage. The converter offers several advantages, including fewer semiconductor and passive components, a smaller size compared to conventional converters, the ability to interface with multiple voltage sources, and self-protection capabilities. First, mathematical models of the PV system and battery are described. Next, the electrical model of the converter and its control system are developed, and mathematical relations are established between the inputs and output. Finally, the converter is simulated, fabricated, and tested. Results demonstrate that the proposed converter achieves higher efficiency than traditional converters and rapidly compensates for transient variations in PV power. This makes it well-suited for DC or AC microgrid applications.
