| 摘 要： | 针对传统单相PWM整流器控制方法存在的PI调节器的静态误差和开关频率高、开关损耗大的问题,提出了一种新型的基于空间矢量控制的单相三电平电压型PWM整流器.首先分析了单相三电平电压型PWM整流器的工作原理,然后给出了模态选择判别方法,制定了开关表.该方法很好地对交流侧电流进行了控制,实现了交流电子负载对于功率因数模拟的要求.最后通过Matlab/Simulink仿真验证了该控制方法的正确性.

| Abstract: | In consideration of the problem of the static error,switching frequency and loss being greater of the PI regulator by means of the conventional single-phase PWM rectifier controlling,this paper puts forward a novel single-phase three-level voltage type PWM rectifier based on space vector control,which firstly analyzes the operating principles of this type of rectifier,then,presents the distinguishing method for mode selection and makes a switch table.The presented method is better for controlling the AC-side current and realizing the require-ments for the power factor simulation by AC electronic load.Finally,by Matlab/Simulink simulation,it verifies the availability of this control method. |
