Abstract

Multilevel inverters are considered as one of the industrial solutions for high power medium voltage and power quality demanding applications due to reduced EMI and EMC issues, reduced total harmonic distortion, lower switching frequency etc. This paper presents the total harmonic distortion (THD) analysis of output current for three level diode clamped multilevel inverters for both resistive and inductive loads. The PWM technique used here is Sinusoidal Pulse Width Modulation (SPWM).By comparing the current THDs, the advantages of inductive load over the resistive load is confirmed. The simulations are performed using MATLAB/SIMULINK software and the results were presented.
