摘要
为实现近距离条件下柔性小型化线圈无线传能的高效稳定,通过HFSS软件对磁耦合谐振线圈进行了设计和分析,设计的无线传能发射及接收线圈的尺寸分别为2 cm×2 cm和1 cm×1 cm;采用聚酰亚胺柔性基底,使得收发线圈具有共形能力,在传输距离为8 mm时传能效率可达75%以上。通过仿真分析了柔性线圈弯曲半径对传能效率的影响,研究结果表明:对于非对称收发线圈,接收线圈在不影响传能效率的情况下可以进行较大幅度的弯曲变化。本研究工作对可穿戴/植入式无线传能设备中柔性耦合线圈的设计具有一定参考价值。
In order to achieve efficient and stable wireless energy transfer of flexible miniaturized coils under close range conditions,a pair of magnetically coupled resonant coils were designed and analyzed by HFSS software.The size of the transmitting coil and the receiving coil are 2 cm×2 cm and 1 cm×1 cm,respectively.The flexible polyimide substrate was used to make the wireless power transfer coils easy to conformal design.The power transfer efficiency is over 75%when the transmission distance between the two coils is 8 mm.The influence of the bending radius of the flexible coil on the energy transfer efficiency was analyzed by simulation.The simulation results show that for the asymmetric transmitting and receiving coils,the bending angle of the receiving coil has a much smaller impact on efficiency.This rsearch has certain reference significance for the design of flexible coupling coils in wearable and implantable wireless power transfer equipment.
