| 摘 要： | PWM整流器与交流电机的定子电路有很大的相似性,采用交流电机磁链观测的方法构造出虚拟的电网磁链矢量,作为PWM整流器矢量控制中的定向矢量,可以达到取消交流侧电网电压传感器降低PWM整流器硬件成本的目的。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的三电平PWM整流器虚拟电网磁链定向矢量控制的仿真模型。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 re-move 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/Simulin... |
