用于具有任意气隙的PCB和铜箔磁性元件的二维解析铜损模型

The modeling and optimization of copper losses are the basis of magnetic designs. By solving 2-D diffusion and Laplace equations, this article proposes a 2-D analytical copper loss model for printed circuit board inductors and transformers with arbitrary air gaps. The copper loss resistance is decoupled into skin, proximity, and fringing resistances. The fringing resistance is caused by the inhomo...
