        abstract = {The Selective Harmonic Elimination (SHE) technique is the most significant harmonic elimination method employed in multilevel inverters to reduce harmonics. For any odd harmonics, the desired value equated to zero for the harmonics to be eliminated.  After forming nonlinear transcendental equations and solving those equations, the values 1 to k are computed. These nonlinear equations show multiple solutions and the main difficulty is its discontinuity at certain points where no set of solution is available.  This limitation is addressed by using Particle Swarm Optimization (PSO).  The function of switching angles is used to formulate the objective function and the constraints. The PSO algorithm is used to compute the switching angles. By implementing these angles as additional switching angles per quarter cycle of the output voltage waveform, the harmonics are reduced or eliminated.  This study takes into account two multilevel inverters—Seven level and eleven level. The performance is measured by the output voltage's THD. It is found that, PSO based switching angles greatly reduces the THD when compared with the normal switching},
