In general, it is known that magnetic induction (MI) wireless power transfer (WPT) is used at a short distance (~several millimeters) and magnetic resonance (MR) WPT is applied at a longer distance (more than several tens of centimeters). In this letter, it is shown that the MR coil can be robustly designed to have higher efficiency, even when the load impedance changes significantly at short distances. The simulated power transfer efficiencies of MI and MR coil show that the MR coil was more insensitive to load impedance than the MI coil. A 1:4 single input and multiple output (SIMO) MR coil wasdesigned and fabricated. Its performance with the variation of load impedance was verified through measurement.

高效磁共振 SIMO WPT 在短距离内对负载阻抗不敏感

一般来说,众所周知,磁感应(MI)无线电力传输(WPT)用于近距离(~几毫米),而磁共振(MR)WPT用于较长距离(超过几十厘米) . 在这封信中,它表明 MR 线圈可以稳健地设计为具有更高的效率,即使负载阻抗在短距离内发生显着变化也是如此。MI 和 MR 线圈的模拟功率传输效率表明 MR 线圈比 MI 线圈对负载阻抗更不敏感。设计并制造了一个 1:4 单输入多输出 (SIMO) MR 线圈。通过测量验证其随负载阻抗变化的性能。
