An induction motor drive inverter with a decreased number of switches is shown. If you're working with medium or high voltage power electronic drives, a multilevel inverter is your best bet. Utilizing a unique ability to synthesize a sine wave with fewer harmonics using several DC sources. For high voltage applications, this concept presents a three-phase framework that may be expanded in both modular and cascaded configurations. Using just four active switches in the conduction channel, this topology may create negative polarity without an H-bridge structure, which reduces power losses and voltage stress on the switches. Using the PSO method, this work presents a novel way of determining the optimal magnitude of DC sources because of the wide range of switching patterns that may be used. The optimal switching angle (OSA) modulation method is used to calculate the ideal switching angles via the PSO algorithm to increase voltage quality and decrease total harmonic distortion (THD). 25 and 31 level MLI is designed and analyzed result using the suggested topology and its optimization technique are shown to be viable.
