Abstract
The work presents two levels Voltage Source Inverter (VSI) fed Direct Torque Control (DTC) of Asymmetrical 6-phase Induction Motor (A6PIM) for electrical drives applications. The proposed control strategy has very fast torque control and is more efficient and commonly used technique for AC machine drives. In order to meet the needs of 6-phase industrial drive, the model uses modified Space Vector Modulation (mSVM) technique to maintain the switching frequency constant by means of which switching losses are kept fixed. The simulation results forecast and validate the efficacy of the proposed method.
