This brief presents a single-phase, single-stage inverter designed to mitigate solar energy fluctuations through a battery energy storage system (BESS). This inverter fulfils important requirements of the solar PV-based system, such as the elimination of leakage current and enabling voltage boost capability while reducing volume and cost. Additionally, it possesses several important benefits, including the ability to perform maximum power point tracking, simultaneous charging/discharging of the BESS, and active power decoupling, ensuring optimal performance under varying atmospheric conditions. Also, its single-stage operation and continuous input current features enhance its suitability for PV applications. Finally, the experimental results verify the performance and effectiveness of the proposed topology.
