This The direct torque control (DTC)operation merely depends on the selection of inverter switching sequences with look-up table thereby stator flux of the motor is not exactly equal to desired reference which causing high flux and torque ripple. This paper considers the effect of switching sequences of space vector modulation (SVM) and advanced space vector modulation (ASVM) on the performance of DTC. The SVM comprises unique pattern of switching sequences whereas ASVM is having two different patterns of switching sequences in the every sector which influences on the d-q axes flux distortion it shows significant effect on the ripple. The interpretation of ASVM versus SVM switching sequences required for the analysis of flux and torque ripple is shown with the case study of DTC. The flux ripple analysis shows that q-axis flux distortion merely effects on the torque ripple and d-axis flux distortion effects on flux ripple. The performance investigation of induction motor with DTC using SVM and proposed ASVM strategies are verified with simulations and experimental results. The experimental verification is conducted with Opal-RT real time digital simulator
