用于未搭接、低磁导率铁芯的箔绕组的横截面可以修改，以减少总绕组损耗。确定了最佳横截面形状为线性切割，并建立了基于该横截面的箔绕组损耗计算模型。与有限元分析确定的损耗相比，该损耗模型具有较好的精度。损耗模型已被用于实现确定特定应用的最低损耗横截面的优化。
The cross section of foil windings used in ungapped, low-permeability cores can be modified to reduce total winding loss. The optimal cross-section shape is determined to have a linear cut out and a loss model is developed to calculate the winding loss in foil windings with this cross-section. The loss model shows excellent accuracy when compared to the loss determined by finite-element analysis. The loss model has been used to implement an optimization that determines the lowest loss cross-section for a particular application.
