چکیده
Multilevel inverters (MLIs) are commonly used in photovoltaic power stations, wind farms, and other forms of renewable energy generation. This study presents a new novel multi-gain switched capacitor (SC) based structural approach. The voltage gain of the proposed design (PD) can be increased threefold by utilizing two switching capacitors and nine switches. Additional significant benefits of the PD include lower voltage stress, an inherent self-balancing of the capacitor voltage, and a minimal amount of switching components. A backside H-bridge is not required to generate negative voltage levels. The PD provides a detailed explanation of the structural analysis, the self-balancing mechanism, the optimum capacitance value, and the control approach. In order to highlight the advantages of the PD, a fair comparison is presented with the most recent seven-level single-source topologies. Finally, Simulation results confirm the accuracy of the theoretical analysis and a prototype has been constructed to demonstrate that the practical findings are doable andsuccessful, with the efficiency tested reaching ۹۶.۹۵%.کلیدواژه ها
