FINITE‐ELEMENT SOLUTION OF STEADY‐STATE SKIN‐EFFECT PROBLEMS IN STRAIGHT FLAT CONDUCTORS

Abstract

Using an integrodifferential approach to steady‐state skin effect problems, the current density distribution in straight flat conductors is solved by the finite‐element method. The approach takes into account a combination of one‐dimensional finite elements corresponding to the flat conductors and triangular finite elements for the remaining domain outside conductors. The results obtained for a flat conductor placed inside a ferromagnetic medium are compared with analytical solutions provided by finite Fourier transforms. As a final output, besides current density distribution, one can calculate parameters useful to designers such a a.c. resistance and reactance of the straight flat conductors.
