The problems of harmonics of the output voltage of the multilevel inverters is considered as a big issue that need to addressed seriously by the researchers of the power electronics field. There are so many types of controllers have been applied to the multilevel inverters in order to reduce the contains of harmonics of the multilevel inverters output.The aimed of this paper is to review the application of Particle Swarm Optimization (PSO) algorithm for harmonics reduction of the output of the multilevel. Hence a modified of a Cascaded H-Bridge Multilevel Inverters (CHB-MLIs) inverters based on modified PSO has been proposed for harmonics reduction. A proposed model using the PSO algorithm of a modified CHB-MLIS has been simulated based on MATLAB/SIMULINK. Based on the simulation results showed that the effectiveness of the proposed model using in harmonics reduction of the multilevel inverter output.
