Simultaneous data and power transmission in resonant wireless power system
YH Son, BJ Jang - 2013 Asia-Pacific Microwave Conference …, 2013 - ieeexplore.ieee.org
A simultaneous digital data and power transmission method in a resonant wireless power
transfer system is suggested. Especially, we suggested a new amplitude shift keying (ASK)
transmitter architecture, where a drain bias of class E power amplifier is switched
alternatively between two voltage levels with respect to input data. The suggested method
has a variety of advantages such as simple architecture, easy to adjust of modulation index
and duty rate, and constant efficiency characteristics. A maximum 5 W class E power …
