High Performance of Matrix Converter Fed Induction Motor for IPF Compensation by Using New DSVM Method

Abstract

In the matrix converter (MC) system to improve the input current quality with low harmonic components, as well as to reduce the input voltage distortion supplied to the MC by using input filters. The major consequence of the paper is about the inter harmonics appearing in the induction motor drive.. In this paper, we propose a new direct space vector modulation (DSVM) method to achieve the required displacement angle between the input voltage and input current of the MC. The paper illustrates the various inter harmonics elimination methods of SVM inverter fed drive and the associated drawbacks. The drawbacks are eliminated by using New DSVM method instead of SVM method in matrix converter fed induction motor drive. A new switching strategy is introduced based on the maximum compensated angle. Then, power factor compensation algorithms using the new DSVM method to achieve the maximum IPF. In which Compensation algorithm is subsequently proposed using a proportional-integral controller to overcome drawbacks presented in compensation algorithm of SVM method. Simulation and experimental results are shown to validate the effectiveness of the proposed compensation algorithms.
