Justus 9200669This study describes a new approach based on genetic algorithm to suppress the current harmonic contents in output of an inverter. A genetic algorithm is applied to optimize a pulse width modulation (PWM) inverter, which can not only spread harmonic energy but also reduce harmonic distortion. A feasible test is implemented by building a proto type three phase voltage source inverter which is designed and controlled on the basis of proposed considerations. It is verified from a practical point of view that these new approach are more effective and acceptable to minimize the harmonic distortion. Due to the complex algorithm, their realization often calls for a compromise between cost and performance.]]>Bech, M.M., J.K. Pedersen, F. Blaabjerg and A.M. Trzynadlowski,1999Enjeti, P.N., P.D.
