Abstract

For an efficient wireless charging to multiple devices, transmitter (TX) system should be able to control the transmitting power-level by monitoring number of receiver (RX) devices via their identification information and charging status and capacity of each receivers. This work proposes a one-way in-band communication scheme, corresponding system structure, and charging algorithm for efficient one-to-N wireless charging system, which has been verified experimentally.
