Abstract

Multi-level voltage source inverter technology has emerged as an important alternative in the control of high power medium voltage energy. Moreover it can also be used for charged balance controlled amongst the multiple input Dc sources in a given topology. Multilevel voltage source inverters have various advantages: Reduction in the electro-magnetic interference, reduction in the voltage ratings of the power semiconductor switching devices, better output voltage having reduced total harmonic distortion. This paper reviews the different firing scheme for three, five, seven level diode clamp inverter, flying capacitor invertor, cascading H-Bridge multilevel inverter. The comparison can easily be made between harmonic distortion values a voltage and current waveforms.
