说明：  基于Ip/Iq方法控制PWM整流器，能够实现直流电容的稳压和有功无功解耦控制,采用电压空间矢量（间接电流控制）技术进行反馈控制，分析直流侧负载突变时，直流电容、输入电流的动态性能
(PWM rectifier controlled by Ip/Iq method can realize the decoupling control of DC capacitor voltage and active and reactive power. The feedback control technology of voltage space vector (indirect current control) is used to analyze the dynamic performance of DC capacitor and input current when the load of DC side changes abruptly.)
