A soft-charging high-gain 13-L SC-based inverter

Multi-level inverters (MLI) have become increasingly popular due to their ability to maximize renewables’ power capabilities and energy efficiency in high-frequency power distribution systems. The proposed design additionally uses phase disposition pulse width modulation to softly charge the capacitor during switching, automatically balancing the voltage across it. When compared to existing MLI topologies, the suggested 13-L SC-based architecture uses fewer components, lower costs, a lower standing voltage, and lower switching losses. The proposed 13-L SC-based MLI worked well in both R and R-L load tests and was supported by both MATLAB software and experimental analysis.
