磁共振耦合无线电能传输系统中中间线圈的最佳位置和尺寸

The Optimal Location and Size of an Intermediate Coil in a Magnetic Resonant Coupling Wireless Power Transfer System

Kedi Yan, Gregory E. Moore, Joshua R. Smith

摘要:

为了增加无线功率传输(WPT)系统的传输距离,我们提供了在标准五线圈轴向对齐实验设置中选择中间线圈最佳位置的指南。根据我们的结果,对于谐振频率处的S21的最大幅度,我们发现存在发射器和中间线圈之间的耦合系数以及接收器和中间线圈之间的耦合系数相同的最佳位置。此外,在给定的对称和非对称设置中,在中间线圈的谐振频率处S21的最大幅度的最佳外径被发现大于TX和RX两者。

英文摘要:

To increase the transmission distance of Wireless Power Transfer (WPT) systems, we provide guidelines on choosing the optimal location of an Intermediate Coil with respect to size within a standard five-coil axially aligned experimental setup. From our results, for maximum magnitude of S21 at the resonant frequency we found the optimal location to exist where the coupling coefficient between the Transmitter and the Intermediate Coil and the coupling coefficient between the Receiver and the Intermediate Coil are identical. Additionally, the optimal outer diameter for the maximum magnitude of S21 at the resonant frequency of the Intermediate Coil in the given symmetric and asymmetric setup are found to be larger than both TX and RX.
