Abstract

We studied a CMC model with a one-turn toroidal core, which is easily used in 3D field simulators. The calculation model of a CMC differs from the actual shape, so we need to correct the CMC's characteristics. When we calculated the noise-suppressing effect of the CMC, we used relative permeability, which differs from the actual value, to approximate the actual characteristics of a CMC. From the comparison of calculated results with measurement results, the calculated results were comparable to the measurement results. We confirmed the validity of our model.

三维磁场模拟器共模扼流圈的简化模型
研究了一种易于应用于三维场模拟器的单匝环形磁芯CMC模型。CMC的计算模型与实际形状不一致,因此需要对CMC的特性进行校正。在计算CMC的降噪效果时,我们使用与实际值不同的相对渗透率来近似CMC的实际特性。从计算结果与测量结果的比较来看,计算结果与测量结果相当。我们证实了我们模型的有效性。
