| 摘 要： | 人工心脏大多通过穿过皮肤的导线进行供电,人为制造了一个可能的感染源,且给病人的日常生活造成很多不便,为了解决这一问题,设计了一套透皮能量传输系统,利用电磁感应原理通过非接触耦合进行能量传递,实现人工心脏植入人体后的无线能量传输.试验研究了该系统变压器次级线圈匝数、开关频率及变压器气隙的大小对系统性能的影响.结果表明:变压器初级线圈30匝、次级线圈60匝时,传输效率最高,性能最好；开关频率为40 kHz时,系统传输效率最高；透皮能量传输系统的传输效率随变压器气隙的增大而减小,当气隙在0～3 mm范围内时效率在60％～80％之间；气隙超过3 mm时效率明显降低.

| Abstract: | Most power supply of artificial heart was provided by wire across skin,which might cause infection and was inconvenient to patient daily life.To solve this problem,based on electromagnetic induction,a transcutaneous energy transmission system was designed to transfer power by non-contact coupling.Wireless energy transmission efficiency of artificial heart implemented in human body was realized by the proposed system.The effects of transformer secondary windings coil,switching frequency and transformer air gap size on the system were investigated by experiments.The results show that the transformer has best performance with primary coil of 30 circles and secondary coils of 60 circles.When frequency reaches 40 kHz,the system has maximum transmission efficiency.The transmission efficiency decreases with the increase of gap size.The efficiency is 60% to 80% in the air gap range of 0-3 mm,while it decreases obviously for the air gap over 3 mm. |
