This paper presents a direct torque control with space vector modulation method for matrix converter drives. It is possible to combine the advantages of matrix converter with the advantages of the DTC strategy by using space vector modulation algorithm of matrix converter and direct torque control strategy of induction motor. The proposed control system has been validated through simulations with...
This paper presents a new, accurate and simple calculation method to determine the switching frequency as well as semiconductor losses and junction temperatures in direct torque controlled induction motor drives. Instantaneous values of the switching frequency, semiconductor losses and junction temperature can be obtained on the basis of mechanical operating point data and the stator flux vector location...
This paper presents a high performance direct torque control (DTC) theme for the induction motor (IM). To solve those problems associated with conventional DTC, such as high current, flux and torque ripple, variable switching frequency, the space vector modulation (SVM) is implemented in the DTC to guarantee the constant switching frequency of the inverter. Meanwhile, the design of a robust speed...
