摘要
The paper emphasis the importance of DTC for an induction motor with multi level inverter in order to reduce the frequency of switching for the IGBT'S for same hysteresis bands of torque and flux. The simulations were completed in SIMULINK software. Simulation results from conventional NPC-DTC and modified NPC-DTC are presented and compared. Results shows that torque, flux linkage and stator current ripples are decreased with proposed NPC-DTC strategy. Evaluation was made based on the motor performance, which are like reduction of switching cycles and improvement in flux responses.
