摘要

无线电力传输系统可以在完全电气隔离的情况下，将能量从励磁侧传输到负载侧，灵活、方便、安全。合理设计系统耦合线圈的结构和参数，可以在一定区域内产生相对均匀的磁场，提高系统的抗偏置性能。本文通过有限元仿真分析了不同结构双d线圈对应的磁场均匀性。在找出最佳情况后，加入铁氧体进行磁屏蔽，并对其屏蔽效果进行了研究。实验结果表明，该优化方法可使磁场均匀性指数提高10.2%，互感波动率降低5%。

Improving the Misalignment Tolerance of Wireless Charging System by Uniforming Magnetic Field of Double-D Coil

The wireless power transmission system can transmit energy from the excitation side to the load side under the condition of complete electrical isolation, which is flexible, convenient and safe. Reasonably designing the structure and parameters of the system coupling coil can produce a relatively uniform magnetic field in a certain area and improve the anti offset performance of the system. In this paper, the uniformity of magnetic field corresponding to different structures of double-D coil is analyzed through finite element simulation. After finding out the optimal situation, ferrite is added for magnetic shielding, and its shielding effect is studied. The experimental results show that with the proposed optimizing method, the uniformity index of the magnetic field can be improved 10.2% and the mutual inductance fluctuation rates can be decreased 5%.
