Abstract:  Based on both double space vector modulation of matrix converter and discrete space vector modulation (DSVM) strategy of direct torque control technique, a new direct torque control system of induction motor fed by matrix converter was proposed, in which more voltage vector was supplyed to control the torque and the flux. Simulation results showed that the system had good performance in dynamic and static condition.
