| 摘 要： | 三相电压型PWM整流器与三相交流变频调速电机定子电路有很大的相似性.采用类似于交流电机磁链观测的方法来构造一个虚拟电网磁链,可以代替电网电压作为PWM整流器矢量控制中的定向矢量,达到省去交流侧电网电压传感器,降低PWM整流器成本的目的.根据交流电机磁链观测器的设计方法,设计了虚拟电网磁链观测器,并构造了基于Matlab/Simulink的PWM整流器虚拟电网磁链定向无电网电压传感器的仿真模型.仿真结果验证了观测器的可靠性和控制方案良好的动静态特性.

| Abstract: | The main circuit of the PWM rectifier is similar to that of an AC machine fed by an inverter. So a virtual line flux has been constructed to serve as the oriented vector instead of the line voltage vector to remove the AC voltage sensors and reduce the cost of PWM rectifiers. A simple virtual line flux observer is proposed based on the method used in AC machines. A simulation model of the AC voltage sensorless virtual line flux oriented vector control of PWM rectifier has been established using Matlab/Simulink. Good steady and dynamic characteristics of this control scheme have been shown by simulation results. |
