| 摘 要： | 将PWM整流技术应用于能量回馈装置,是实现可再生能量回馈利用的经济而又环保的方法。介绍了能量回馈装置的主电路拓扑结构,并建立了该电路的数学模型,在此基础上,根据PWM整流器与交流电机的相似性,分析研究得到PWM整流器的虚拟磁链模型。从实现单位功率因素有源逆变控制出发,设计了PWM整流器的控制系统。通过Matlab/Simulink仿真表明,主电路设计合理,控制系统具有良好的动静态性能。

| Abstract: | PWM rectifier is applied to energy feedback equipment,it is an economical and unpolluted method.The main circuit topology is introduced and mathematical model is built.The main circuit of the PWM rectifier is similar to that of an AC machine.So a virtual line flux has been constructed to serve as the oriented vector control.The control system is analysed and designed in order to satisfy the Unity-Power-Factor(UPF) condition.As a result,good steady and dynamic characteristics of the control system have been shown by simulation. |
