order harmonics are eliminated for an eleven level cascaded multilevel inverter. Simulation results of a seven level cascaded multilevel inverter and an eleven level cascaded multilevel inverter are provided for different levels of modulation indexes. The simulation results show that moth-flame optimization model solves the harmonic elimination problem, total harmonic distortion minimization problem efficiently.
