document: A new voltage-vector selection algorithm in direct torque control of induction motor drives AC drives based on direct torque control of induction machines allow high dynamic performance to be obtained with very simple control schemes . The drive behavior , in terms of current , flux and torque ripple , is dependent on the utilised voltage vector selection strategy and the operating conditions . In this paper a new voltage vector selection algorithm , which allows a sensible reduction of the RMS value of the stator current ripple without increasing the average value of the inverter switching frequency and without the need of a PWM pulse generator block is presented Numerical simulations have been carried out to validate the proposed method
