摘　　要：针对所提出的软开关AC/DC变流器 ,基于软开关变流器的工作原理和空间矢量控制机理 ,通过分析、仿真和实验 ,研究了 4种SVPWM波形的谐波成分和谐振环开关频率 ,从而确定适合该软开关AC/DC变流器的最佳逼近方式和SVPWM波形。给出了仿真和实验结果。In the paper the four kinds of approaching modes are researched for the proposed soft switched AC/DC rectifier based on the operation principle of soft switch rectifier and the control principle of space vector. The harmonics components of the four kinds of SVPWM waves and the switching frequency of resonant link are investigated. The optimal approaching mode and the SVPWM wave to be fit for the soft switched AC/DC rectifier are selected. The results of simulation and experiment are presented.
