中文摘要

本文提出了一种用于平面磁性元件的非线性集总参数模型。该技术通过麦克斯韦方程的一维分析,为多层平面磁性元件开发了等效电路模型。导电层被表示为阻抗网络,绝缘区域则建模为空心电感,并进一步扩展以表征磁性材料的非线性特性。

English Abstract

A nonlinear lumped element model for planar magnetics is presented. This technique develops an equivalent circuit model for multilayer planar magnetic components using 1-D analysis of Maxwell's equations. Conducting layers are represented as impedance networks, while the insulating regions are modeled as air-cored inductors. The equivalent circuit model is extended by representing the nonlinear ma...
