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 کاملComparison of Direct Torque Control of Induction Motor Using Two-Level and Three-Level Inverter
This paper compares the performance of direct torque control of induction motor using two-level and three-level inverters. The main objective of this paper is to improve the performance of direct torque control of induction motor using three-level inverter without affecting its simplicity. The basic switching table based direct torque control of induction motor using two-level inverter is first...
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 کاملFour-Switch Inverter-Fed Direct Torque control of Three Phase Induction Motor
In this paper, four-switch inverter fed direct torque control three phase Induction Motor drive is presented. A triangular wave is used as dither signal of minute amplitude (for torque hysteresis band and flux hysteresis band respectively) in the error block. This method minimizes flux and torque ripple in a Four-Switch inverter fed induction motor drive while the dynamic performance is not aff...
متن کاملDirect Torque Control of Induction Motor Using Multilevel Inverter
. This paper proposes the three level diode clamped multilevel inverter fed direct torque control of induction motor. The proposed multilevel inverter has the advantages of fewer harmonic in the output and low torque ripples. The switching table direct torque control scheme is adopted due to the simplicity of the control algorithm. The PI speed controller is used in the outer loop. To demonstra...
