| 摘 要： | 在人体消化道微机电系统无线能量传输系统中,线圈间的耦合程度是影响传输效率的关键因素之一.本文对空间任意位置的两个线圈建立耦合模型,提出了一种计算线圈耦合系数的方法,分析了轴向偏移、径向偏移、角度偏移对耦合程度的影响,与实验结果吻合较好.最后利用这种方法,比较分析了能量传输系统中发射线圈的两种布置方式.

| Abstract: | In the wireless power transmission system for remotely implanted MEMS,the coupling coefficient is one of the most crucial factors affecting transmission efficiency.A coupling model was built up for two coils in arbitrary spacing.A formula for calculating coupling coefficient was induced.The relationship between coupling coefficient and axial,lateral and pitch misalignments was numerically analyzed.The results met with experiments quite well.By this method,finally,two ways of laying transmitting coil modes were compared. |
