Özet
This study on the elimination of harmonics which form in three-phase asynchronous motors driven by inverters uses genetic algorithms (GA), one of the optimization methods, to suppress the undesired harmonics. By the use of Matlab/Simulink program, the study aims to identify the optimum switching angles in the optimum number. Optimum switching angles are the angles which make the first harmonic amplitude the biggest and the harmonic largest first-harmonic amplitudes which is to eliminated the smallest. The model has been developed by using sinusoidal pals width modulation (SPWM) technique in simulink environment. No technical help of this model using the (standard condition) the harmonic values, the values of the harmonic occured by using SPWM and the results obtained with GA is presented in tables and graphs and analyzed the differences between them. As a result, greatly reduced of harmonics clearly shown also with the help of graphs in the study made with GA. ©2011 Academic Journals.
