Multilevel inverters are developed as an extension to the conventional inverters. They are widely used for high power applications as they cause very less disturbances and have the possibility to function at lower switching frequencies than ordinary two-level inverters. This paper compares different topologies of inverters .The comparison is done with respect to Total Harmonic Distortion. This paper presents a brief account on the most important topologies like diode-clamped inverter (neutral-point clamped), capacitorclamped (flying capacitor), and cascaded H-bridge with separate dc sources. It also presents the most relevant control and modulation methods developed for this family of inverters namely sinusoidal pulse width modulation and space-vector modulation. Multilevel inverter promises a lot of advantages over conventional inverter especially for high power applications. Main advantages are that output waveforms were improved since multilevel inverter produces nearly sinusoidal output voltage waveforms, hence the THD will be low. Multilevel converter applications focus on industrial medium-voltage motor drives, utility interface for renewable energy systems, UPS, flexible AC transmission system, and traction drive systems.
