中文摘要：

在PWM整流器控制中，同步旋转坐标系下的电流控制方法以及双闭环结构被广泛采用。然而分别控制有功电流和无功电流的方法，致使电流不能快速跟踪参考电流，没有达到很好的控制效果。阐述了限制电流动态响应的原因。提出了改进方法。仿真和实验结果表明，这种控制策略具有优良的稳态性能和快速的动态响应。

英文摘要：

In the control of PWM rectifier, direct current control and dual close loop control structure in synchronous rotating coordinate are widely adopted. However, the method of separately controlling the active and reactive current causes current fail quickly tracking the reference current and does not achieve expected control results. The reason of restricting current dynamic response was analyzed and the improved method was given. Simulation and experiment results show that the proposed control method has perfect steady-state characteristics and fast dynamic response.
