摘要
A hybrid algorithm for the computation of rectangular conductor per unit length internal impedance is developed. Up to a switching frequency, the internal impedance is computed using a two dimensional analytical formula developed by Giacoletto. For these frequencies, 150 terms of Giacoletto infinite sum give a sufficiently good approximation. For higher frequencies, it is shown that the rectangular conductor can be quite accurately approximated by a cylindrical conductor. The proposed hybrid algorithm, for higher frequencies, features improved accuracy and speed when compared to the Giacoletto formula truncated after a small number of terms.
