With the undeniably increasing environmental problem, sustainable power innovation has become a consistent subject of discussion. The turn of events, and also the usage of the pulse width modulation inverter, is a critical link in the implementation of appropriate electricity. In addition, one of the most serious problems with the activity of PWM inverters is over -modulation. Over Modulation (OM) technology can successfully enhance output critical voltage and current, reduce framework dynamic reaction time, and expand the working area of a consistent phase. Even though it was only briefly mentioned in the writing, the orderly examination has yet to be distributed. To make an impact this study covers the current state of research, challenges that have arisen, and the advancement of the OM technique for PWM inverters. The significant problems with the excessive modulation approach are discussed.
