| 摘 要： | 提出了一种针对中点钳位式三电平逆变器供电感应电动机的直接转矩控制策略。该控制策略基于12扇区划分，转矩控制器采用4级滞环形式，并且考虑了中点电位的控制。最后用仿真来验证该算法的有效性。

| Abstract: | A direct torque control strategy of induction motor fed by three-level neutral-point-clamped inverter is presented. It has 12 sectors, employing a 4-level torque hysteresis loop comparator. Also it presents an algorithm for avoiding capacitor voltage unbalance. Finally, results obtained with simulations is shown to verify the availability of the strategy. |
