中等传输距离下的无线功率传输链路 第1部分:实现工作状态最优化

Medium range wireless power transfer links. Part 1:Optimal operating regimes

中程无线功率传输(WPT)可以采用几种不同的方式实现,如通过电感或电容耦合、谐振或非谐振网络实现.本文主要研究了通过感应耦合谐振器实现的WPT链路,而且只着重研究了利用2个谐振器的链路(直接链路)并工作在主谐振频率下的情况.研究结果表明,当工作在主谐振频率下,可以根据网络参数来对传输效率或负载功率进行优化.

Medium-range wireless power transfer （WPT） can be realized in several different ways,e.g.by using in-ductive or capacitive coupling and resonant or non-resonant networks.This contribution focuses on a WPT link im-plemented by inductively coupled resonators.The case of a link using just two resonators （direct link） and operating at the main resonant frequency is investigated.It is shown that the operation at the main resonant frequency allows optimizing either efficiency or available power on the load,depending on the network parameterization.
