Abstract
- To drive a totally implantable artificial heart for a long period with transcutaneous energy transmission, it is necessary that the temperature rise of devices implanted inside the human body is minimized. In this paper we study the properties of a transcutaneous DC-DC converter which transfers energy from an external source to a vibrating flow pump within the body, The temperature rise of the internal rectifying circuit has been rectified by as much as 30% to 50% by employing synchronous rectifiers rather than Schottky diodes, In addition, we have investigated a method for controlling the vibrating flow pump (VFP). This pump would be a constituent part of a totally implantable artificial heart. Also, the use and current limitation of an implanted rechargeable battery for emergency use is discussed.
