Abstracts: Power electronics device which convert dc power to ac power at required output voltage and frequency is known as inverter. Inverter is broadly classified into single level inverter and multi level inverter. Multilevel inverter as compared to single level inverter has like minimum harmonic distortion, reduce EMI/RFI Generation can operate on several voltage level. Now to control voltage within the inverter is possible using PWM method. 180 degree pulse can produce at output, to control the voltage width of the pulse should be change and it will fully automatic using controller programming.
