Regardless of its progressive popularity, the presence of unwanted harmonics in the voltage output of multilevel inverters is a critical concern. These harmonics indicate dreadful results for electrical as well as mechanical equipment: (1) It increases the losses, developed due to switching which reduces the capability of equipment (2) due to these harmonics ripples are generated in torque and speed of the motor (3) and it degrades the quality as well as life of framework due to mechanical exhaustion and torque vibrations. When it is connected to an electrical network, the low harmonics are critically undesirable as they cause different issues at the distribution systems. To over-power these issues, enormous research had been done to control/reduce the impacts of harmonics in multilevel inverters. Proposing a proper switching plan for the power switches, which can generate the least Total Harmonic Distortion (THD), is the most vital perspective. In this paper, an improved optimization technique to decrease the harmonics is proposed, which efficiently decreases harmonics with less arithmetic computation. The productiveness of the proposed technique is also confirmed via simulations results and hardware setup.
