ABSTRACT
This paper presents a novel DTC-SVM method for matrix converter (MC) fed induction motor. The advantages of DTC method are combined with the advantages of the matrix converter based on space vector modulation (SVM) technique. This proposed novel method provides a precious input power factor control capability beside the high control performances. Furthermore, Conventional principles of DTC and SVM of MC were described. The combination of the two was given in detail. The FFT spectrum analysis of the input current shows the better harmonic contents as compared to the conventional DTC method. Finally, the simulation and experiment research were carried out to identify the new method effectiveness. The results of induction motor control at both steady state and transient state are shown to improve the low-speed performance and strong adaptability of this novel control strategy.
