基于SVPWM的Vienna整流器矢量控制策略的研究

针对传统两电平整流器和三电平整流器的不足,在能量不需要双向流动的应用场合,本文深入研究了一种三相三开关三电平Vienna整流器;基于该整流器的拓扑结构,分析了其基本工作原理,提出了一种基于SVPWM的Vienna整流器的电压外环、电流内环的双闭环矢量控制策略;最后搭建了Vienna整流器矢量控制仿真模型,通过Matlab环境下的仿真分析,证实了该整流器控制简单,具有良好的动态性能和静态性能。

Research of vector control strategy of the Vienna rectifier based on SVPWM

According to the shortcomings of the tradional two-level rectifier and three-level rectifier,In the situation of the energy don't need double-way flow,Further research on the three-phase three-switch three-level Vienna rectifier in this paper;Based on the topology structure of this rectifier,analysis on its working principle,and based on the SVPWM,A vector control strategy of the Vienna rectifier was put forward,which use dual closed loop with voltage outer loop and current inner loop;Finally,the vector control simulation model of Vienna rectifier was build,through the simulation analysis in Matlab environment,The results show that the Vienna rectifier has simple control and good dynamic performance and static performance.
