—Multilevel inverters are worked on medium-voltage and high-power applications due to their ability to supply high power quality output voltage. Hence, a low switching frequency strategy is applied in high power applications since it generates lower magnitudes of harmonics than high switching frequency. In this paper, to eliminate high selective harmonic in a 15-level cascaded multilevel inverter, a genetic algorithm approach is proposed. Genetic algorithm is an evolutionary algorithm to determine switching angles 15-level cascaded multilevel inverters in order to eliminate selective harmonic. This paper calculates the optimum angles as offline to eliminate harmonics 3 rd , 5 th ,7 th , 9 th , 11 th , 13 th , 15 th and 17 th along with their multiples. Then, the obtained angles are applied to simulation results to validate the approach performance. Index Terms—Genetic algorithm, cascaded multilevel inverter, selective harmonic elimination (SHE).
