Multi-Level Inverter Modeling and Simulation Using Various and Complex PWM Modulation in MATLAB/Simulink

Abstract: Thispaperpresentsadetailedcomparisonofseveral multilevel inverter (MLI) topologies, including Neutral Point Clamped (NPC), Flying Capacitor (FC), Cascaded H-Bridge (CHB), and Modular Multilevel Converter (MMC). Application domains, control schemes, modularity, voltage balancing, and structural complexity are the main topics of the analysis. Each topology’s component requirements, modulation techniques, and performancetrade-offsareexamined.Simulationresultsvalidate thetheoreticalevaluationandshowhoweachtopologyissuitable forspecificapplicationssuchaselectricdrives,renewableenergy systems, and high-voltage direct current (HVDC) transmission. The study aims to assist researchers and engineers in selectingthe optimal MLI topologies according to the requirements of specific applications.
