Abstract
The major drawback of usual dual three-phase AC machines when supplied by a voltage source inverter (VSI), is the occurrence of extra harmonic currents. These extra currents circulate only in the stator windings and cause additional losses. One solution to reduce their amplitude is to act on the supply side using dedicated PWM control strategies. In this paper, we present a Direct Torque Control technique of a double-star induction motor drive (DSIM). The induction machine has two sets of three-phase stator windings spatially phase shifted by 30 electrical degrees. Each set of three-phase stator windings is excited by a three-phase inverter. Simulation results have been presented to show the effectiveness of the dual-three phase DTC scheme for double star induction motor.
