| 摘 要： | 分析了三相电压型PWM整流器的基本原理并进行了建模。针对传统的双闭环控制下,直流母线电压受负载扰动和电网波动影响较大的问题,根据整流器功率平衡的原则,提出了电压外环采用前馈补偿(负载电流和电网电压)和输出电压反馈的控制方法,该方法有效地改善PWM整流器的抗扰动能力,仿真结果验证了控制策略的有效性和正确性。

| Abstract: | The basic principle of the three-phase PWM rectifier was analyzed and the model was established.With the traditional double-loop control,the load disturbance and grid voltage fluctuations have a great influence on the DC bus voltage.According to the principle of power balance for rectifier,the outer control loop which is based on feed-forward compensation(load current and power voltage) and output voltage feedback control were proposed.This method effectively improves the anti-disturbance ability of PWM rectifier.Simulation results show the effectiveness and validity of control strategies. |
