摘要
用数学方法推导出矩阵变换器主电路开关矩阵调制函数的通解，针对变换器不同的传输性能指标，可对开关调制函数进行相应的优化，函数形式比较简单．在正弦输入和输出的目标下，可获得变换原理限定的最高电压传输率和接近为１的功率因数．给出了部分计算机仿真及实验结果．
The general solution of the modulation function used for the switches of main circuits in matrix converters is derived in this paper. The form of the obtained modulation function can be optimized according to the different transfer performance of converters. When both expected input and output of a converter are sinusoidal, the highest voltage transfer ratio of converter, defined by conversion principle, and a close to one input power factor can be obtained. To verify the derivation, both computer simulation and experiment results are presented.
