Abstract

In this letter, we design a magnetically coupled resonant wireless power transfer (MCR-WPT) system on the conformal cylindrical surface based on the flexible printed circuit (FPC) coils. The coil has the advantages of small size, lightweight, and high bendability. We combine mathematics and simulations to explore the relationship between the self-inductance/mutual inductance of the flexible coil and the bending radius of the conformal cylindrical surface. Both theoretical and simulation results show that as the bending radius decreases linearly, the self-inductance and mutual inductance of the coil also decrease nonlinearly. In addition, as the bending radius decreases, the transmission efficiency (TE) decreases, and the resonant frequency shifts to a higher range. Finally, measured and simulated results agree well, which further validates the conclusions.

基于柔性PCB线圈的圆柱形磁耦合谐振无线输电系统

在本文中，我们设计了一种基于柔性印刷电路(FPC)线圈的共形圆柱面磁耦合谐振无线电力传输(MCR-WPT)系统。该线圈具有体积小、重量轻、可弯曲性高等优点。我们将数学与仿真相结合，探讨了柔性线圈的自感/互感与共形圆柱面弯曲半径的关系。理论和仿真结果表明，随着弯曲半径的线性减小，线圈的自感和互感也呈非线性减小。此外，随着弯曲半径的减小，传输效率(TE)降低，谐振频率向更高的范围偏移。最后，实测结果与仿真结果吻合较好，进一步验证了结论的正确性。

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.
