Abstract :
A DTC-SVM sensorless induction motor control system based NPC three-level is presented in this paper. In order to maintain high performance of the system, accurate stator flux is necessary. A novel phase compensation stator flux observer is proposed in the paper. Furthermore, a three-level phase voltage reconstruction algorithm is proposed as the base of the high precision flux observer firstly in the paper. The simulation and experiment results indicated that the DTC-SVM induction motor can run smoothly and have a high dynamic response with them.
