Abstract: Inverters are power electronic converter that converts DC input to an AC output waveform. These inverters are used to operate sensitive loads so they require better power quality and lower harmonic content. As all the power electronic converters are considered as switches so suitable PWM technique plays a vital role in powering these inverters. This paper attempts to compare the two very popular topologies of inverters like Cascaded H-Bridge Multilevel inverter and Modular Multilevel converter. Performance of Cascaded H-Bridge Multilevel Inverter is viewed by using modulation techniques like In-phase deposition (IPD), Phase opposite deposition (POD) and Alternate Phase opposite deposition (APOD) while Modular Multilevel Converter is viewed under nearest level Modulation (NLM) technique. These are compared in order to have lesser switching losses and lower total harmonic distortion by using MATLAB/SIMULINK simulations.
Keywords: MMC, Cascaded H Bridge Inverter, THD and MATLAB/Simulink.
