This document describes techniques and apparatuses directed at reducing inductive-charging power loss. In aspects, a mobile device includes a multi-layer flexible printed circuit board (FPCB) coil that forms a receiver coil (202) having a Litz-wire structure. The FPCB coil includes a multi-trace bundle, having traces (210) systematically routed throughout the different layers (200, 204) of the FPCB coil to reduce eddy current losses.

Abstract
This document describes techniques and apparatuses directed at reducing inductive-charging power loss. In aspects, a mobile device includes a multi-layer flexible printed circuit board (FPCB) coil that forms a receiver coil (202) having a Litz-wire structure. The FPCB coil includes a multi-trace bundle, having traces (210) systematically routed throughout the different layers (200, 204) of the FPCB coil to reduce eddy current losses.File in questo prodotto:
