Abstract :
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 amplifier with the suggested ASK transmitter was designed using a low cost IRF510 power MOSFET at the frequency of 6.78 MHz.
