摘　　要：通过分析三相三开关三电平(Vienna)整流器的工作原理,研究了该整流器的单周控制策略,并采用电压外环和电流内环的双闭环控制,实现了Vienna整流器的可靠稳定、低谐波畸变特性。基于Matlab仿真平台,搭建了Vienna整流器的仿真模型,仿真结果表明,基于单周控制方法的8 kW三相PFC整流器,控制结构简单,系统可靠稳定,谐波畸变率<3%,功率因数可达99%。By the analysis of three phase three switch three level （Vienna） rectifier principle, one-cycle con- trol method of the rectifier is studied, and the outer inner voltage-current dual closed loop control system is adopted, and reliability and stability and low harmonic distortion characteristics of the Vienna rectifier are realized. The Vien- na rectifier simulation model is set based on Matlab simulation platform, and the simulation results show that the 8 kW three-phase PFC rectifier based on one-cycle control method has simple control structure, high reliability and sta- bility with a harmonic distortion rate less than 3% and a power factor up to 99%.
