研制了同步整流型人工心脏经皮能量传输系统。输入电压为24 V，输出电压为9至18 V。本文表明，采用数字PLL技术的同步整流器的系统的效率在5 mm线圈距离处达到92%的DC-DC效率。采用铁氧体磁芯和数字锁相环技术，消除了整流电路中的电感和电容。电路安装在次级线圈的背面。研制了稳定输出电压的控制系统，并将这一成果应用于其它接触供电系统。
Transcutaneous energy transmission systems for the artificial heart with synchronous rectifiers were developed. The input voltage is 24 V and the output voltage is 9 to 18 V. This paper shows the efficiency of the system with synchronous rectifier using a digital PLL technique achieved 92% DC-DC efficiency at 5 mm coil distance. Using the ferrite core and a digital PLL technique, inductor and capacitor were eliminated from the rectifier circuit. And the circuit was mounted to the back of the secondary coil. And we developed the control systems for stable output voltage and apply this result to other contact power supply system.
