本文提出了一种有效、准确地对多匝线圈进行时域均匀化有限元分析的新方法。该方法将宏观复渗透率用部分分式表示，然后用递归卷积（RC）法进行拉普拉斯逆变换。所提出的方法比传统的有限元分析方法速度快，计算结果吻合较好。此外，该方法的计算结果与实测结果吻合较好。
This article presents a novel method for effectively and accurately performing time-domain homogenized finite-element analysis of multi-turn coil windings. In this method, the macroscopic complex permeability is represented by a partial fraction form, and then, the inverse Laplace transformation is performed using the recursive convolution (RC) method. The proposed method is approximatelyfaster than the conventional finite-element analysis, with good agreement between the obtained results. Moreover, the results obtained by the proposed method were also in good agreement with those obtained by measurement.
