本文提出了一种合成电感器考尔等效电路的新方法，该电路可以表示磁滞、涡流、异常磁芯损耗、直流和交流绕组损耗以及电感。只需测量正弦激励下的电感损耗即可合成 SPICE 损耗模型。所提出的电路模型可用于评估任意电压/电流激励下的损耗。在所提出的方法中，测量的损耗被细分为交流损耗和磁滞损耗。然后，根据损耗模型合成用于 SPICE 仿真的 Cauer 等效电路。结果表明，在有和没有直流偏置电流的正弦波和三角波情况下，所提出的模型评估的损耗与测量结果非常吻合。
This article presents a new method to synthesize the Cauer-equivalent circuit for inductors that can represent the hysteresis, eddy current, anomalous core losses, dc and ac winding losses as well as inductance. Only the measurement of inductor loss under the sinusoidal excitation is required to synthesize the SPICE loss model. The proposed circuit model can be used to evaluate the loss under arbitrary voltage/current excitations. In the proposed approach, the measured loss is subdivided into the ac and hysteresis losses. Then, the Cauer-equivalent circuit for SPICE simulation is synthesized from the loss model. It is shown that the losses evaluated by the proposed model are in good agreement with the measured results under the condition of the sinusoidal and triangular cases with and without dc bias current.
