Description
This document provides a possible approach to the design of a wireless power receiving coil for low-power applications. Manyparameters are involved in such a design flow, therefore different approaches are possible according to which one is consideredthe most relevant one (efficiency, overall quality factor of the coupled resonant circuits, etc.).The overall efficiency of a wireless power transfer system is generally a reasonable starting point. Mechanical constraints and/ornon-ideal alignment of the coils, as well as data-transfer requirements (e.g. ASK modulation index at transmitter side), areremarkably impacting on the whole design.
Typical applications
- Wireless Power, Portable Devices
