A new thirteen-level high-gain soft-charging SC inverter

The article presents a novel switched-capacitor-based inverter with 13 levels, suitable for renewable energy applications with low-magnitude input voltage. The inverter boosts voltage by a factor of six without expensive electronics or controllers. It offers reasonable size, power density, cost per output power, reduced input power DC supplies, and soft charging for capacitors, reducing switching losses. A comparison is made between the proposed structure and previous studies to evaluate the inverter’s efficacy. The research uses simulation and hardware setup to analyze frequency fluctuations, dynamic load changes, modulation indices, and voltage across capacitors. The findings demonstrate the effectiveness of the proposed architecture.
