REDUCTION OF TOTAL HARMONIC DISTORTION OF CASCADE H-BRIDGE INVERTER WITH TUNING SWITCHING PARAMETERS IN OPTIMIZED VALUE

Multilevel inverters have become more convenient over the last years in electrical high power applications because, their outputs are closer to sinusoidal. The cascade H-bridge inverter insert ignore into journalissuearticles values(CHB); is very popular then other multilevel inverter because its control method is very easy when compared with others. In this paper new approach of seven levels Space vector modulation insert ignore into journalissuearticles values(SVM); is utilized to produce required fundamental voltage in CHB.  For minimized total harmonic distortion insert ignore into journalissuearticles values(THD);, switching parameters tuned by meta-heuristic algorithms and this value has been compared with arbitrary values. The simulation results have been carried out using MATLAB/SIMULINK Software.
