Abstract

With the development of wireless power transfer technology, more and more attention has been paid to its electromagnetic safety. In this paper, a novel hybrid shielding structure composed of the innermost fan-shaped ferrite, the interlayer nanocrystalline strip and the outermost aluminum foil is proposed to shield the electromagnetic field of the inductive power transfer system. Eight structure parameters of the proposed shielding are optimized by finite element simulation, in order to reduce the magnetic leakage of the system and improve the utilization rate of shielding materials. In addition, the proposed structure is compared with two types of typical double-layer hybrid shielding from the perspectives of the weight, the coupling coefficient and the magnetic flux leakage. Both simulation and experiment results show that the cost and weight of the proposed shield are about 60% lower than the traditional disk shield. Moreover, the shielding layer proposed in this paper can not only effectively reduce the magnetic flux leakage of the system, but also maintain a high coupling coefficient.

一种新型感应输电系统磁耦合器混合屏蔽结构的研究

随着无线电力传输技术的发展，其电磁安全问题越来越受到人们的重视。本文提出了一种由最内层扇形铁氧体、层间纳米晶带和最外层铝箔组成的新型混合屏蔽结构，用于屏蔽感应输电系统的电磁场。为了降低系统的漏磁，提高屏蔽材料的利用率，对所提出的屏蔽的8个结构参数进行了有限元仿真优化。并从重量、耦合系数和漏磁等方面与两种典型双层混合屏蔽结构进行了比较。仿真和实验结果表明，该屏蔽体的成本和重量都比传统的圆盘屏蔽体低60%左右。此外，本文提出的屏蔽层不仅可以有效地降低系统的漏磁，还可以保持较高的耦合系数。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
