面向自由移动装置的能量发射线圈优化设计
Optimal design of energy transmitting coil for free moving device
人体植入式设备等自由移动装置的使用，使得无线能量传输系统中效率的稳定性成为了研究热点。本文首先分析了无线能量传输系统中效率和磁场强度之间的关系，要实现系统效率的稳定就需要发射线圈能够在上方平行平面内产生均匀的磁场。然后采用遗传算法和Hfss对圈数为14边长为200mm发射线圈的间距进行优化，当线圈间距为[8 8 8 5 8 8 5 8 8 8 8 7 4 4 4]时，上方距离10mm平面处的cov(Standard deviation divided by average）达到最小值3.8%。最后通过实验测量优化的线圈，在线圈轴线上平均取17个点进行测量计算cov为4.1%。这将为以后能量发射线圈的设计提供依据。
Because of Human implantable device and free mobile device, the stability efficiency of wireless energy transmission system becomes a hot research. First, this paper analyzes the relationship between the efficiency and the strength of the magnetic field of wireless energy transmission system, to achieve the efficiency of the system stability requires transmitting coil can produce a uniform magnetic field in parallel planes. Then using the genetic algorithm and Hfss to optimize the coil spacing. Finally, through the analysis ofOptimal design of energy transmitting coil for free moving device the experimental and simulation results show that when the coil spacing is [8 8 8 5 8 8 5 8 8 8 8 7 4 4 4], in the distance above the plane 10mm cov can reach 4.59%. This will provide the basis for the design of energy transmitting coil.
