The five-phase induction motor inherently has the minimal torque ripple. However, when it is controlled by direct torque control (DTC) technique, the torque ripple increases due to the presence of a hysteresis torque comparator. The classical five-level torque comparator is presented in the previous literatures to control the torque ripple. However, this comparator has the drawback of wrong selection...
This paper presents an integrated high power battery charging topology by incorporating a split three phase induction motor for electric vehicle. In charging/vehicle to grid mode, stator winding is used as an inductive filter between grid and converter. During this operation, the rotor of machine is kept in stationary position as rotating magnetic field is cancelled out due to built-in nature of split...
In this paper direct torque control of asymmetric six-phase induction motor is presented. 5th and 7th order current harmonics are observed in the phase currents if conventional Direct Torque Control (DTC) scheme is extended for asymmetric six phase machine. These harmonic components are not responsible for torque production, thus cause losses in motor winding. Synthetic vectors are used in this paper...
