Abstract

Due to their ability to synthesize waveforms with better harmonic spectrum and attain higher voltages, multi-level inverters are receiving increasing attention in the past few years. The multilevel inverter was introduced as a solution to increase the converter operating voltage above the voltage limits of classical semiconductors. In this paper, a Diode Clamped Multilevel Inverter is controlled with Sinusoidal PWM, Third Harmonic Injection PWM and Sixty degrees PWM and the variation of Total Harmonic Distortion in their outputs are observed. Also, a Diode Clamped inverter is controlled by Sinusoidal PWM technique and by varying the modulation index, variation of Total Harmonic Distortion is observed.
