Performance Evolution of Switched Capacitor Boost Nine Level Inverter with Variable Frequency APOD Technique

As electrical power has existed, power quality has been an issue, and in recent years, academics have focused mostly on this issue. Harmonic reduction in inverters is necessary because harmonics play a significant role in power quality and reliable power supply performance. Additionally, this study uses an inventive inverter design that produces 9-level output voltage waveforms using 1 DC source, 8 switches, and 3 capacitors. This Pulsewidth modulation (PWM) technique examines a multicarrier approach that is being used with the Variable frequency alternative phase opposition disposition (VF-APOD) for a nine-level inverter. After being obtained, the comparison is made between the conventional approach and the line voltage and total harmonic distortion (THD). Also, this study generates gating signals using the PWM approach, guaranteeing the improved output waveforms. The study also includes numerous simulation results obtained using MATLAB-SIMULINK, offering a full assessment of the proposed configuration's precise effectiveness under distinct modulation index.
