Space Vector Modulation Technique for Direct Torque Control of Induction Motors
نویسندگان
چکیده
The PWM principle is used to control the output voltage of the three-phase inverters. There are many possible PWM techniques proposed in literature. Among these the space-vector PWM (SVM) method is an advanced PWM method and is possibly the best among all the PWM techniques for variable-frequency drive applications. The classical SVPWM which is used in the direct torque control of induction motor has the possible dynamic locus of the stator flux, and its different variation depending on the VSI states chosen. This locus is divided into six different sectors. The switching frequency used in this classical DTC method is high which causes switching losses.

Tuning of fuzzy controller coefficients in direct torque control with space vector modulator for the three phase induction motors drive using Metaheuristic algorithms with considering electrical faults.
Among all the drive control methods of induction motors, the Direct Torque Control (DTC) method operates independently of the rotor parameters of the machine and, despite its simplicity, provides good torque control in both stable and transient modes. The use of residual comparators in these drives reduces the torque ripple and variable switching frequency. The most common solution is the use o...

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...
