活体植入式系统体外射频电源的设计与讨论

DESIGN AND EXPERIMENT OF TRANSDERMAL RF POWERSUPPLY OF IN VIVO IMPLANTABLE SYSTEM

研究了植入系统中电源的设计，并进行了实验。根据活体生理环境的特殊需要，给出一个满足供电系统要求的体外射频供电电源，该电源具有体积小、功率大、安全可靠的特点。着重研究了线圈耦合位置对供电效率、输出电压的影响，对各种失配引起的供电效率下降、输出电压不稳定做了详细的实验和讨论，并提出改进措施。

The design and experiment of powersupply for implanted system are introduced in this paper.To fit the specific requirements of physiological circumstance,a new transdermal RF powersupply is provided.The effect of coil misalignments on efficiency and output voltage are fully explored.The reductions of transmission efficiency and output voltage,which are caused by coil misalignments,are studied in detailed experiments and analysis.The paper also puts forward some new methods to improve the transmission efficiency.
