| 摘 要： | 利用AC/AC矩阵式直接变换原理,分析了带有高频隔离变压器的AC/DC变换器电路工作模态。将基本空间矢量进行优化组合,解决了高频变压器双向磁化中的复位问题。从理论上推导了电压传输比,采用PI调节器实现了系统的闭环控制。通过数字仿真与实验验证了分析方法的正确性。

| Abstract: | The work modes of three-phase AC/DC converter with high frequency transformer based on AC/AC matrix converter are proposed in this paper.The reset problem of dual magnetization in the high frequency transformer is solved by the optimization of the basic space vectors.The voltage ratio is derived and the system closed-loop control is realized with PI regulator.The digital simulation and experimental results demonstrate the correctness of the analysis. |

| Keywords: | converter/Space Vector Modulation(SVM) work mode closed-loop control |
