Abstract:
The paper mainly focus on the study of the comparison of harmonic analysis executed by voltage source inverter using Fast Fourier Transform in MATLAB/Simulink. Here the comparison analysis of THD obtained for line voltage through simulation as well as mathematical model has been performed. It investigates the effect of Total Harmonic Distortion on the adjustable ac drive system. If THD is minimized at the output terminal of the inverter than rotor current, rotor speed and torque performance is improved which results in smooth operation. Paper also include the comparison analysis of line and phase voltage with respect to THD. The performance comparisons are analyzed in term of Fast Fourier transform and THD. The proposed work for THD analysis for VSI fed induction motor drives is modeled in MATLAB/Simulink software.
