One-to-N Wireless Power Transmission System Based on Multiple Access One-Way In-Band Communication

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 paper 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. The resonant magnetic coupling can significantly enhance the efficiency and transfer range of a Wireless Power Transmission (WPT) system and potential applications of the WPT are ranging from mobile charging platform to wireless electric vehicle charging.
