Level Shifted PWM Technique for Minimum Component Switched Capacitor Inverter

Nowadays, Multi-Level Inverters (MLIs) incorporating switched capacitors have become increasingly important for applications in both highvoltage AC scenarios and the renewable energy sector. The High Gain Switched Capacitor (HGSC) technique, designed to achieve the necessary output voltage magnitude, strategically utilizes a reduced number of DC sources based on capacitor voltage. Overcoming the challenge of designing a highly efficient, high-gain MLI with minimal sources and switches requires a comprehensive approach. The present study presents a new Nine-Level High Gain inverter topology that employs fewer capacitors, switches, and diodes compared to other HGSC-MLI configurations. The innovative inverter arrangement utilizes only one DC source, eight switches, and two capacitors to achieve Nine-Level output voltage waveforms. The Nine-Level High Gain inverter exhibits a remarkable ability to consistently generate high-quality voltage output under diverse conditions, employing modified PWM control techniques. The Phase Disposition Pulse width Modulation (PDPWM) technique is employed in this paper. Simulation studies have been meticulously conducted using MATLAB/Simulink, verifying the suggested nine-level inverter topology's efficiency.
