Abstract :
The improvement method of a flat secondary transcutaneous transformer for a resonant converter that transfers several W of power across a large variable human skin gap is presented and built. The secondary transformer is piled, and the coupling coefficient, conversion efficiency and temperature rise are measured with an experimental set up. The coupling coefficient and the conversion efficiency are increased compared with the conventional transformer. The temperature rise is decreased compared with the conventional transformer
