| 摘 要： | 本文对矩形截面导体的内阻抗进行数值计算,提出了利用几何平均距离的导数计算磁感应强度,以及利用边界积分法计算磁场储能来得到内电感的方法。实例计算表明这两种新算法的性能优于常用的通过磁矢势求解内电感的算法,并能得到可信的误差估计。

| Abstract: | Internal impedance of conductors of rectangular cross section is calculated in this paper. Two new numerical methods are presented, including computing magnetic inductive intensity via the derivative of geometrical mean distance, and calculating the magnetic energy via the integral on the perimeter, to determine the internal inductance. It is exemplified that, with a credible error estimation, their performances are superior to the frequently-used one, which determine internal inductance via the vector magnetic potential. |
