Abstract: Nowadays, multilevel inverters (MLIs) are receiving profound attention to cater the power requirements of industry 4.0. In this context, newer MLI topologies are being explored as well as proposed with reduced component counts to attain higher levels of output voltage. In this context, this article illustrates the comparative analysis of sinusoidal pulse width modulation (SPWM) with two different carrier wave and low frequency modulation (LFM) for a 3-phase symmetrical modular multilevel inverter (M-MLI) with reduced component counts. Since, this topography is uncomplicated and modular, it could be extended to several levels by rising the number of cells. The M-MLI topology having 3-levels in each pole with a single fundamental cell in each phase is simulated in MATLAB/Simulink. The %THD of M-MLI using LFM scheme is found less compared to other two techniques which are demonstrated through FFT analysis
