Abstract
A wireless transcutaneous energy transmission system has been developed for totally artificial hearts. The complete system includes a dc-to-dc converter, a dc-to-high-frequency transfer circuit, a coil-coupling structure, and a high-frequency-to-dc rectifying circuit. The power transfer is stabilized by feedback control the phase of the input impedance of the resonant circuit. Experiment results showed that the output voltage variation was kept within ±0.4 volts when the coil spacing varied from 6 to 18 mm. The optimized conversion efficiency of this system was about 68 % when the output power was 36 watts.
