Abstract
This paper presents the selective harmonic elimination of cascade H-bridge multilevel inverters using shuffled frog leaping algorithm. This algorithm takes the advantages of the genetic-based memetic algorithm and the social behavior-based PSO algorithm. In addition, this study provides a new fundamental modulation technique with SHE for multilevel inverters which can generate output waveforms with a full range of modulation indices. There are two control objectives formulated as a multi-objective optimization problem. The mentioned algorithm finds the optimal solution set of switching angles. Simulation is performed in MATLAB to confirm the validity of the proposed method
