摘要
趋肤效应是高频电流传输中需要充分考虑的问题。文章分析了现有文献对趋肤效应分析的不足,从麦克斯韦方程组出发,推导出了适用于任意截面形状长导体电流趋肤效应的二维数值分析方法,并介绍了如何用MATLAB语言进行软件编程来实现该方法。给出了一个计算实例,分析了矩形截面导体交流损耗同频率和导体厚度之间的关系,并同现有文献的结论进行了对比。
Skin effect should be well considered in high frequency current transmission. This paper analyzes the shortages of the skin effect analysis in current literatures. Based on the Maxwell＇s Equations, the 2D Numerical analysis method of the Skin Effect which fits for long conductor of any forms of interface is deduced. The programming method by Matlab is introduced. An example is given to validate this method. Based on this method, the relationship between the AC loss and the frequency along with the thickness of the conductor is analyzed. The analysis results are compared with the current literatures. At last conclusions are given.
