Multilevel Inverters (MLI) are mostly used for medium and high-power applications. MLI generates high quality output voltage by using Selective Harmonic Elimination technique (SHE-PWM). Using Newton-Raphson (NR) method, Genetic algorithm (GA) and Artificial Bee Colony Algorithm (BEE) based SHE-PWM technique is implemented for Cascaded H-Bridge type MLI to generate the five-level output. The proposed algorithms estimate the proper switching angles to eliminate the lower order harmonics. This paper deals with elimination of fifth harmonic compared to all other algorithms mentioned BEE is easy to implement for real -time applications. Simulation results and experiment results are reported for the exactness and effectiveness of the proposed methods.
