利用有限元分析软件对间隙铁心电感绕组的交流损耗进行了分析，得到了较好的结果。然而，该过程变得非常耗时，特别是如果绕组在气隙附近成形。缺乏封闭形式的解决方案，优化成型绕组强调需要替代技术提供解决方案比运行有限元模拟所有可能的导体布置更快。在这项工作中，提出了一种新的技术，用于优化的形状平面电感器绕组，但应适用于较大的低频电力系统组件进行微小的调整。磁通密度作为从气隙的距离的函数的估计使用一个非常简单的模型和随后的损失计算使用第一原理方法具有良好的结果。仿真结果得到了实验验证。
AC-loss analysis in gapped-core inductor windings can be performed using finite element analysis (FEM) software with good results. The process however becomes very time consuming especially if the winding is shaped in the vicinity of the air gap. The lack of closed form solutions for optimization of shaped windings emphasizes the need for alternative techniques offering solutions quicker than running FEM-simulations for all the possible conductor arrangements. A novel technique for optimisation of shaped planar inductor windings is proposed in this work but should be applicable to larger low frequency power system components with minor adjustments. The flux density as a function of the distance from the air gap is estimated using a very simple model and the subsequent losses calculated using a first-principle method with good results. The simulated results are verified experimentally.
