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. Transcutaneous energy transmission has been widely used for the power supply of the implantable medical de-vices .The most important study on the transcutaneous energy transmission is about how to improve its transfer efficiency and dis-tance .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 transmis-sion .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 veri-fied the theoretical analysis .
