  Abstract: In this article a reliable and efficient switching technique has been proposed to decrease the total harmonic distortion. The total harmonic distortion has harmful effects on electrical devices. Also, leads to increase the temperature in neutral wire of distribution transformers due to over current in power system. The total harmonic distortion has improved by using the proposed technique to eliminate the lower order selection harmonic. Using pulse-width modulation technique is requirement as switching pattern to eliminate the selective harmonic. Therefore, an optimized technique has been proposed to eliminate the lower order selective harmonic for a triple level invertors. The efficiency of the proposed method has been validated and justified through a Simulink in MATLAB software. Also, the proposed technique compared with current pulse-width modulation technique.
