摘　　要：对采用高频隔离结构的AC-DC矩阵变换器进行分析,通过空间矢量调制技术合成交—交及交—直变换开关函数,在此基础上,借助Matlab软件搭建控制系统模型.仿真结果体现出良好的系统输入输出性能,并实现了拖动阻感负载的四象限输出,为AC-DC矩阵变换器在直流可逆调速系统的进一步研究提供基础.An AC-DC matrix converter with high frequency isolation was analyzed. The switching functions for cycloconvertor and rectifier were obtained by introducing space vector modulation. On the basis of these theories, the simulation model of control system was built by means of MATLAB. The simulation results validate the excellent input and output characteristics of matrix converter, and realize the four-quadrant operation of dragging. And it can give help to the further studies of AC-DC matrix converter in direct current reversible speed control system.
