摘要
为改善交-交变频器的性能,对双变量相控理论的固定点换流策略进行了研究。利用Matlab软件进行仿真实验,找到了影响固定点换流策略换流相位角(电流过零点的相位)的影响因素,得到了一些频率下固定点换流的最佳相位角,为交-交变频调速提供了指导依据。
In order to improve the performance of AC-AC frequency converter, researches on the fixed point inverter strategy of double variable phase control theory. The simulation experiment is made by using Matlab software and finds out the reasons that influence on the phase angle (the zero current phase) of fixed point inverter strategy. The best phase angle of different frequency fixed point inverter are found, which provides guide for AC- AC frequency converter.
