3-Phase Induction motor speed control based space vector modulation technique for direct matrix converter under unbalanced conditions

Abstract

In this work, the performance analysis and discussion of a space vector modulation technique used for a three-phase direct matrix converter feeding a three-phase induction motor is presented. For this, the induction motor models and the method of the space vector modulation technique are developed. Then, the overall electrical drive system is simulated using MatLab/Simulik software. Results obtained from simulation are the harmonic spectrum analysis of the motor current and the total harmonic distortion for unbalanced input voltages. These results show the good performance of the control system strategy.
