Optimization of Cascaded H-Bridge Multi-Level Inverter using Particle Swarm Optimization Technique for Reduction of THD

Development of Multilevel Inverters (MLI) have been increasing for the various application. This paper presents seven level single phase of cascaded H-Bridge MLI with the help of PSO Algorithm. The purpose to choose the PSO Algorithm is its simplicity and efficiency. Through this algorithm, we are evaluating the swapping angles in order to reduce the total harmonic distortion(THD). For the verification of the performance of proposed algorithm, a suitable model has been developed with the help of MATLAB/SIMULINK. Then the simulation outcomes are verified by experimental results through hardware model. All the outcomes are verified analytically, simulation and experimentally.
