摘要
为解决体内无创检测装置的能量供给问题,设计出一无线能量传输系统,并根据系统的互感模型分析能量传输效率,得出了影响能量传输效率的主要因素是发射和接收线圈之间的互感系数。为实现系统的高效能量传输,应尽量提高互感系数。最后实验分析了两线圈的半径、位置和角度偏移对互感系数的影响,为提高无线能量传输效率提供了方法依据。
A wireless energy transmission system is designed for the energy supply of micro detection device inside human. The mutual inductor model is established to analyze the factors affecting the energy transmission efficiency and then the conclusion that the biggest mutual inductance is essential to achieve the highest efficiency is obtained. At last, the relationship between the mutual inductance, which is the main factor of efficiency, and the radius, the position and angle displacement of two coils is analyzed with experiments, thus a method to enhance the energy transmission efficiency is provided.
