摘要

经皮能量传输方式是目前植入式医疗设备系统供电方式的研究热点，研究如何提高其传输效率和传输有效距离具有重大的应用价值.本文在分析互感耦合理论的基础上，结合互感耦合和强磁耦合的特点，提出了一种适用于经皮能量传输的三线圈耦合结构，并对其进行了相关的理论推导.结果表明：当耦合系数小于0.25时，三线圈耦合结构对耦合效率具有增强作用；在耦合系数为0.04时可提高将近一倍的效率.实验结果也很好地验证了理论分析结果.

Abstract

Transcutaneous energy transmission has been widely used for the power supply of the implantable medical devices.The most important study on the transcutaneous energy transmission is about how to improve its transfer efficiency and distance.Based on the analysis of the mutual inductance coupling theory

and combining with the characteristics of the strongly coupled magnetic resonances

this paper proposed a three-coil coupling structure which is more suitable for transcutaneous energy transmission.The theoretical analysis indicates that the proposed three-coil coupling structure strengthens the coupling efficiency when the coupling coefficient is less than 0.25 and nearly doubles the efficiency when the coefficient is 0.04.The experimental results verified the theoretical analysis.
