This paper deals with the synthesis of an RL Cauer ladder network to homogenize multiturn windings in time‐domain finite element (FE) computations. In frequency domain, the macroscopic model of eddy currents in the winding can be described by frequency‐dependent complex impedance and reluctivity for skin and proximity effects respectively. To represent those in time domain, two RL Cauer networks are synthesized to match each, with the accuracy depending on the order of the network to be appended. The proposed method yields an improved accuracy as compared with the previous work in which the topology of the ladder network was not well chosen. The results are validated by means of a 2‐D axisymmetric inductor with a nonlinear gapped core.

基于RL Cauer梯形网络的多匝绕组绕组的时域均匀化

本文讨论了RL Cauer梯形网络的合成，以在时域有限元（FE）计算中均化多匝绕组。在频域中，绕组中涡流的宏观模型可以分别由频率相关的复数阻抗和对皮肤和邻近效应的磁阻来描述。为了表示时域网络，将两个RL Cauer网络进行合成以匹配每个网络，其准确性取决于要附加的网络的顺序。与没有很好地选择梯形网络的拓扑的先前工作相比，所提出的方法具有更高的精度。通过带有非线性间隙磁芯的二维轴对称电感器验证了结果。
