  • For medium voltage and high-power application generally, multilevel inverter is used as an energy conversion device. Advantages of multilevel inverter are lower switching losses, total harmonic distortion, less voltage stress on switches than conventional inverter. This review paper presents a comparative study of performance parameters when different level shifted multicarrier Pulse Width Modulation (PWM) techniques are implemented on a 15-level asymmetric H-bridge multilevel inverter using a topology having less number of switches with different loading conditions. Three modulation techniques have been used here. The techniques used are PD-PWM, POD-PWM, and APOD-PWM. Here R, R-L and IM loads are used. The operation is simulated in MATLAB SIMULINK. The FFT analysis of the three modulation techniques used has been done when implemented on different loads and their respective THD data has been tabulated.
