In this paper, the authors focus on, elimination of harmonics of a cascaded multilevel voltage source inverter. Here the basic concept is to eliminate specific harmonics with a proper choice of switching angles. In this paper, Genetic Algorithm (GA) optimization technique is use to achieve proper switching angles for reduce the THD and elimination of a selective lower order harmonics with fundamental components at the desired values. As a case study, the proposed method is simulated on a seventeen levels and fifteen levels inverter and optimum switching angles are determined to eliminate low order harmonics and to minimize THD.
