Abstract. Optimizing switching angles in multilevel inverters is explored in this study based on MATLAB simulation. The objective is to achieve selective harmonic elimination (SHE) to eliminate specific low order harmonics while having the fundamental output voltage. The work emphases solution of transcendental equations in SHE for a range of modulation indices from 0 to 1 by employing a group of metaheuristic algorithms including genetic algorithm (GA), gray wolf optimization (GWO), particle swarm optimization (PSO), slim Mould algorithm (SMA), and whale optimization algorithm (WOA). The algorithm performance in terms of the total harmonic distortion (THD) governs the selection of the optimal switching angles for a specific value of the modulation index. The analysis and visualization of algorithm performance are tested within MATLAB environment which offers insights into the effectiveness of biologically inspired optimization techniques for power quality enhancement in multilevel inverter systems.
