摘要

谐振耦合无线电力传输（WPT）系统的输出电压对线圈对中非常敏感。本文提出了一种新型的四极线圈结构作为自动导引车（AGV）静态充电的接收线圈，以改善自动导引车充电过程中XOY面不对中情况下的互感分布。改进的线圈结构有效地降低了输出功率和电压波动。建立了实验样机，验证了所提WPT系统的可行性。实验结果表明，在覆盖整个充电平面77.78%的线圈面积偏置面积范围内，输出电压波动仅为10.85%。

A Coil With All-Plane High Misalignment Tolerance for Wireless Power Transfer

The output voltage of a magnetically resonance-coupled wireless power transfer (WPT) system is very sensitive to the coil alignment. In this paper, a novel quadrupole coil structure as a receiving coil for static charging of automated guided vehicles (AGVs) is proposed to improve the mutual inductance profile under XOY plane misalignment conditions during AGV charging. The enhanced coil structure effectively reduces the output power and voltage fluctuations. An experimental prototype is established to validate the feasibility of the proposed WPT system. The experimental results show that the output voltage fluctuation is only 10.85% over a 77.78% coil area offset area covering the whole charging plane.
