چکیده
This paper presents the application of Space Vector Pulse Width Modulation (SVPWM) technique to reduce torque ripple in an induction motor employing Direct Torque Control (DTC). The effective time is determined using imaginary time vector there by the lengthy procedure of using reference voltage vector is eliminated. Also the sector identification and angle determination are not used. Simulation studies have been carried out for proposed method and results are compared with the classical DTC .The results shows that the torque, current and flux waveforms are superior to that of classical DTC. The performance of the drive system is evaluated through digital simulation using MATLAB-SIMULINK package.

Space Vector Pulse Width Modulation with Reduced Common Mode Voltage and Current Losses for Six-Phase Induction Motor Drive with Three-Level Inverter
Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

Direct torque control (DTC) is a control technique in AC drive systems to obtain high performance torque control. The classical DTC drive contains a pair of hysteresis comparators and suffers from variable switching frequency and high torque ripple. These problems can be solved by using space vector depending on the reference torque and flux. In this paper the space vector modulation technique ...
