Multilevel inverter hasplayed a vital role in medium and high power applications in the recent years.In this paper, Reduced Switch Count Multi Level Inverter structure RSCMLItopology is presented with different pulse width modulation techniques. Theharmonic level analysis is carried out for the reduced switch count multilevelinverter with the different PWM technique such as with Alternate PhaseOpposition Disposition APOD method, In Phase Disposition IPD method and multi reference pulse widthmodulation method for five level, seven level , nine level and eleven levelinverter. The simulation results are compared with the cascaded H Bridge MultiLevel Inverter CHBMLI. The nine level RSCMLI inverter with APOD method isused for the Distribution Static Synchronous Compensator DSTATCOM applicationin the nonlinear load connected system forpower factor improvement. The result shows that the harmonic level and thenumber of switches required for RSCMLI is reduced compared to CHBMLI. RSCMLIemployed in DSTATCOM improves the power factor and harmonic level of the systemwhen it is connected to the nonlinear load.
