摘要

在这封信中，分析和优化了适合智能服装的无线充电箱。该线圈结构经过优化，可在各种抽屉尺寸下产生均匀磁场。采用亥姆霍兹-电磁线圈混合结构，与电磁线圈相比，耦合系数的变化从78.2%降低到26.4%。研究了多抽屉柜的两种设计方法。在第一种方法中，线圈针对单个抽屉进行了优化。在第二种方法中，线圈通过考虑整个抽屉柜来优化。测量结果表明，第二种方法进一步减小了放置在不同位置的接收线圈的充电电流变化。

Design and Optimization of Wireless Charging Drawer Coil for Smart Garments

In this letter, wireless charging chests suitable for smart garments are analyzed and optimized. The coil structure is optimized to generate a uniform magnetic field in a variety of drawer sizes. With the hybrid Helmholtz–solenoid coil structure, the variation of coupling factor is reduced from 78.2% to 26.4% as compared with solenoidal coil. Two design approaches for multidrawer chest are examined. In the first approach, the coils are optimized for individual drawers. In the second approach, the coils are optimized by considering the entire drawer chest. The measurement results show that the second approach further reduces the variation of charging current of receiver coils placed at different locations.

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
