Coil-Capacitor Circuit Design of a Transcutaneous Energy Transmission System to Deliver Stable Electric Power

초록

A new transcutaneous energy transmission (TET) system was developed for transmitting electrical power to an implanted device, such as an artificial heart in a patient's body. This new design can maintain a stable output voltage independent of the load resistance. The system includes a compensation capacitor to reduce energy loss and increase power transfer efficiency. Experimental results show that the output voltage of the receiving coil changes very little as the load resistance varies from 14.8 Omega to 15 k Omega, which corresponds to a change in output power from 0.1 to 97 W.
