摘要

Harmonics measurement of an industrial unit is done to aid the power quality aspects in a typical factory. The real issues are the harmonics generated by the inverters which affects the induction machine performance. Several inverters like Voltage Series Inverters, PWM fed Inverters, Multilevel inverters etc. exist in literature. Amongst all these, multilevel inverters have been very popular due to its several advantages. But there is a challenge of optimal design of the inverter and optimal selection of pulse width of each level so as to get minimal Total Harmonic Distortion. For these reasons a novel multilevel inverter design based on Particle Swarm Optimization is proposed in this paper for obtaining the optimal width of the pulse of each level so as to get minimal Total Harmonic distortion. The results has been compared to that of the existing techniques and found to be quite better than the existing ones.
