Abstract—Thispaper deals with reduced number of switches in multilevel inverter. Asymmetrical inverter has been used with the topology of cascading the fundamental unit. The grounds behind using multilevel is forenhancing the power quality and scaling down the distortions in waveforms. The output waveform attained is quite closer to sinusoidal waveform with a very low distortion. The switching is in a sequenceand flexible for increasing or cutting down the voltage levels when desired. The switching methods with pulsewidth modulation have been discussed. And a comparative study of different topologies of symmetrical as well as asymmetrical inverter of different levels has been done. Lastly, the simulated results from Simulink/MATLAB is presented.
