摘要

本文提出了一种采用铁氧体和金属屏蔽的屏蔽线圈结构。将其与非屏蔽线圈结构(即一对环形线圈)进行比较,以证明磁场分布和系统性能的差异。利用三维有限元分析(FEA)工具进行的仿真结果表明,该方法可以有效抑制100w级无线电力传输(WPT)系统的漏磁场,提高系统性能。

Shielded coil structure suppressing leakage magnetic field from 100W-class wireless power transfer system with higher efficiency
In this paper, the shielded coil structure using the ferrites and the metallic shielding is proposed. It is compared with the unshielded coil structure (i.e. a pair of circular loop coils only) to demonstrate the differences in the magnetic field distributions and system performance. The simulation results using the 3D Finite Element Analysis (FEA) tool show that it can considerably suppress the leakage magnetic field from 100W-class wireless power transfer (WPT) system with the enhanced system performance.
