摘要: In this paper, we present a new Direct Torque Control (DTC) scheme for induction motors using three-level neutral point clamped (NPC) voltage source inverter (VSI). order to develop high dynamic performances, propose approach, in which enhance the responses of torque and flux with optimal switching strategies. Serious problems caused by significant fluctuations middle inverter. As consequence these problems, obtain an asymmetric output non-zero average value. Our proposed solution uses hysteresis comparator regulate input voltages NPC An enhanced direct control “EDTC” is simulated DC balancing motor. obtained results demonstrate stability performances.
