| 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. |
