利用磁场分布的勒让德展开，我们推导了磁片频率相关特性的标准考尔电路表示，并讨论了其物理意义。推导了非线性电感的表示形式，以便将Cauer电路应用于硅钢动态磁滞建模中。该电路仅使用一个或两个迟滞元件即可准确地重建脉宽调制激励下的迟滞特性。
Using the Legendre expansion of the magnetic field distribution, we derive the standard Cauer circuit representation of the frequency-dependent properties of magnetic sheets and discuss its physical meaning. The representation of non-linear inductors is derived so as to apply the Cauer circuit in the dynamic hysteresis modeling of silicon steel. This circuit accurately reconstructs the hysteretic property under pulsewidth modulation excitation using only one or two hysteretic elements.
