Wireless powering management by analog circuitry based in-band signaling controller

摘要

Efficient wireless charging control scheme for powering a single device unit is presented. The proposed scheme uses in-band communication and analog circuits to control the clock signal lengths. Since it can generate the control data packets without MCU, it is easy to implement a one-chip of the RX parts. We have verified the performance of the in-band communication for the WPT system while a mobile device is in charging.
