Direct Torque Control for Three-Level Neutral Point Clamped Inverter-Fed Induction Motor Drive
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 ...

متن کاملAnalysis of 2-Level and 3-Level Inverter Fed Direct Torque Control of Induction Motor Drive
AC drives are more predominant than dc drives. Ac drives require control of frequency, current and voltage for variable-speed applications. The difference between the traditional vector control and the DTC is that the DTC has no fixed switching pattern. The DTC switches the inverter according to the load needs. Though conventional DTC (CDTC) is simple, easy to implement generates substantial st...
متن کاملA Novel Scheme for Reduction of Torque Ripple in Direct Torque Control of Three Phase Squirrel Cage Induction Motor Using Seven Level Neutral Point Clamped Inverter
Direct torque control of a 3 phase squirrel cage Induction motor though offers a good dynamic response and is free from dynamic coordinate transformation has a major disadvantage of producing rippled torque which degrades the performance of entire drive system. A scheme is proposed in this study which employs seven levels Neutral point clamped inverter which helps in alleviating the torque dist...
