| 摘 要： | 针对基于直接转矩控制的异步电动机运行时存在较大的电流及转矩脉动问题，该文提出一种新的控制方案。该方案是在原来两电平逆变器的基础上增加一个Boost电路，以使异步电动机的电流及转矩脉动减小，并且使变频器开关频率降低。仿真结果表明该方法案能有效地解决电流及转矩脉动的问题。

| Abstract: | Due to the large torque ripple and current ripple of asynchronous motors based on direct torque control at operation status,this paper proposed a new control strategy.On the basis of two-level inverter,a Boost circuit was added to decrease the torque ripple and inverter frequency. The simulation shows that it can efficiently solve the problem of torque ripple and current ripple. |
