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