摘要

在这封信中,我们提出了一种使用可重构发射机的距离自适应无线电力传输(WPT)系统。所提出的变送器包括一个主线圈和一个具有可调电流的辅助线圈。可配置辅助线圈直接控制耦合强度,可减轻因距离变化引起的耦合过度或耦合不足。通过仿真和实验验证了WPT系统的距离自适应能力。透射系数的测量表明,近距离(15毫米)最大增加64%,远距离(110毫米)最大增加57%。整体有效传输范围提高了59%。提出的设计提供了一种简单而有效的距离适应方法,同时保持紧凑的系统尺寸。

Compact Distance-Adaptive Wireless Power Transfer Using a Reconfigurable Auxiliary Coil
In this letter, we propose a distance-adaptive wireless power transfer (WPT) system using a reconfigurable transmitter. The proposed transmitter incorporates a main coil and an auxiliary coil with adjustable currents. The auxiliary coil can be configured to directly control the coupling strength, which can mitigate excessive or insufficient coupling caused by distance variations. The distance adaptation capability of the proposed WPT system is verified through both simulations and experiments. Measurements of transmission coefficients show maximum increase of 64% at close range (15 mm) and 57% at long range (110 mm). The overall effective transmission range has been improved by 59%. The proposed design offers a simple yet effective approach to distance adaptation while maintaining compact system dimensions.

期刊介绍: IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
