Abstract— The output power of a solar power generation system (SPGS) can fluctuate significantly due to environmental factors, impacting the stability and reliability of the power distribution network. To address this, a new SPGS design with a built-in power smoothing function is proposed. The system includes a solar cell array, a battery pack, a dual-input buck-boost DC-AC inverter (DIBBDAI), and a boost power converter (BPC). The DIBBDAI handles voltage boosting, bucking, and DC-AC conversion within a single unit, while the BPC serves as a battery charger between the solar cell array and the battery pack. In this setup, DC power from either the solar array or the battery is directly converted into AC power through a single-stage process, enhancing the overall power conversion efficiency. Similarly, the solar array charges the battery through a single-stage conversion. This streamlined approach improves energy efficiency across the solar array, the battery system, and the grid. To mitigate the effects of sudden changes in solar output, the battery charges or discharges as needed, helping to smooth the system’s power output. Additionally, the DIBBDAI reduces leakage currents caused by the parasitic capacitance of the solar array. Overall, the proposed interface not only boosts power efficiency and stabilizes power output but also minimizes leakage current in the SPGS. A hardware prototype has been developed and tested to validate the system’s performance.
