Abstract

In this letter, we propose a wireless power transfer (WPT) system with conformal receivers based on parity-time (PT) symmetry. The transmitter is constructed by a negative resistor powered parallel LC circuit, including a planar transmitting coil. The two receivers are both of parallel LCR topology with flexible coils as the inductance. The transmission characteristics of the system are analyzed and verified under different conformal conditions of the two receiving coils. The theoretical analyses and experimental results show that whether the two receiving coils are planar or cylindrical, the PT symmetric state can be achieved and robust transmission features can be obtained in the strong coupling region. The proposed WPT system can provide references for practical wireless charging platforms when deformations of electronic devices occur and multi devices need to be charged.

基于 PT 对称性的多保形接收器无线电力传输系统

在这封信中，我们提出了一种基于奇偶校验-时间（PT）对称性的保形接收器无线功率传输（WPT）系统。发射器由负电阻供电的并联 LC 电路构成，包括一个平面发射线圈。两个接收器均采用并联 LCR 拓扑，以柔性线圈作为电感。在两个接收线圈不同的保形条件下，对系统的传输特性进行了分析和验证。理论分析和实验结果表明，无论两个接收线圈是平面还是圆柱形，都能实现 PT 对称状态，并能在强耦合区获得稳健的传输特性。当电子设备发生变形并需要对多个设备进行充电时，所提出的 WPT 系统可为实用无线充电平台提供参考。
