摘要/Abstract:
This paper presents an inductive power transfer system for implantable medical devices. The system features a DC/DC converter in transmitting side, and a load voltage monitoring circuit in receiving side, plus a communication mechanism that utilizes the power coils. The load voltage monitoring circuit detects the voltage on the load and once it is out of nominal range, an alert is sent to the transmitter through wireless communication. The transmitter then adjusts the DC/DC output voltage/transmitting power accordingly, to keep the load voltage relatively constant. The closed-loop response time can be as fast as 69ms, and the receiver efficiency is over 88%, while the overall efficiency can be up to 76% under a wide range of load and distance conditions.
