Analysis & Comparison Multilevel Inverter Topologies

Abstract

As the multilevel inverters synthesize waveforms with better harmonic spectrum and less
harmonic distortion, are considered as an optimal choice for high voltage and high power
applications, but the choice of suitable topology for respective application is the major
concern. The paper gives detail analysis and comparison of three major topologies of
multilevel inverter i.e. Diode clamped MLI, Flying capacitor MLI &cascade MLI on the
basis of complexity of the circuit, power quality, required component and implementation
cost.
