摘要

针对海底无线电力传输系统，研究了通过海水传输提高电力传输效率的方法。研究了不同直径、不同工作频率、固定匝数下螺旋线圈谐振器的空载Q (Qu)和耦合系数(k)。此外，我们还引入了一种新的四层螺旋线圈谐振器结构，发现它的传输效率得到了提高，特别是采用了密集缠绕的利兹丝。

Study on high efficiency WPT underseas

Aiming at the undersea WPT (Wireless Power Transfer) system, improvement of power transfer efficiency through saltwater is studied. We have examined the unloaded Q (Qu) and coupling coefficient (k) of the spiral coil resonators for different diameters and different operating frequencies with the number of turns fixed. In addition, introducing a new structure of 4-layered spiral coil resonators, we found the improved transfer efficiency, especially by adopting dense winding of litz wire.
