Abstract :
Three-level inverter brushless doubly-fed motor control system have obtained widespread concern because of its advantages such as high pressure, good reliability, high efficiency and low current harmonics. Aiming at three-level Neutral Point Clamped inverter Brushless Doubly-Fed Machine direct torque control system, a three-level fixed resultant vector BDFM Direct Torque Control method is proposed based on midpoint voltage hysteresis control. The stability and dynamic characteristics of the proposed control method were analyzed in MATLAB / SIMULINK. Finally, the system´s hardware platform was built and the experimental results verify the feasibility and effectiveness of the proposed method.
