Design of Modular Multi-Level Inverters by Using MATLAB

Recently., the utilization of inverters has been increased across various applications. Inverter is an electronic device that transforms DC power into AC. By employing precise gate signals., the proposed nine-level inverter generates AC output voltages at nine distinct levels., offering numerous advantages over conventional 9-level inverters., including fewer switches., reduced THD (Total Harmonic Distortion)., enhanced efficiency., and cost-effectiveness. Multilevel inverters produce highly accurate output waveforms., closely resembling sinusoidal waves. This research study validates the results by using MATLAB SIMULINK software to analyze the output voltage and current waveforms. Furthermore., this research study provides an insightful overview of various multilevel inverter types., such as diode-clamped., cascaded H Bridge Inverter., and flywheel inverters. From this study., it is evident that the multilevel inverters are increasingly adopted in medium voltage and high-power applications.
