Abstract
Contact-type rotary electronic devices have the disadvantages of easy wear and no electrical isolation, which is not conducive to the safety and reliability of the device. In this paper, a contactless rotary inductively coupled power transfer (ICPT) device has been proposed, which provides electrical isolation, higher flexibility and greater security. The device consists of a rotary loosely coupled transformer, S/LCC compensated resonant converter and a DC-DC converter. To verify the analysis and design, a 400W rotatable prototype with a 50mm gap was fabricated and tested. An overall efficiency 84.3% was achieved from DC 40V input to DC 40 V output.
