Limited available space and some other system requirements for the integration of magnetic components address the importance to improve their overall performance and reduce losses. This article evaluates the performance of planar inductor with Moore fractal design. The inductor is modeled using partial inductance method, where each segment is divided into a certain number of elementary filaments, and then, mutual inductances between filaments are calculated. A developed simulation tool is used for the analysis of high-frequency parameters (equivalent inductance, equivalent resistance, and quality factor), taking into account parasitic effects. The proposed model is verified by measurements and electromagnetic simulations. Two planar fractal inductors, with different segment widths, 2.9 and 3.6 mm, are examined. A good agreement between the results obtained by modeling, measurements, and electromagnetic simulations is achieved. The main advantage of the proposed simulation tool is that it can be easily modified and applied for the modeling and optimization of various inductor geometries, which will be useful in future research.

平面分形电感器的建模与性能分析

有限的可用空间和磁性组件集成的一些其他系统要求解决了提高其整体性能和减少损耗的重要性。本文评估了采用摩尔分形设计的平面电感器的性能。电感器采用部分电感法建模,其中每段被分成一定数量的基本灯丝,然后计算灯丝之间的互感。开发的仿真工具用于分析高频参数(等效电感、等效电阻和品质因数),同时考虑寄生效应。所提出的模型通过测量和电磁模拟得到验证。检查了两个具有不同段宽(2.9 和 3.6 毫米)的平面分形电感器。通过建模、测量和电磁仿真获得的结果之间实现了良好的一致性。所提出的仿真工具的主要优点是它可以轻松修改并应用于各种电感器几何形状的建模和优化,这将有助于未来的研究。
