Abstract

In this article, a muti-relay wireless power and data transfer with 100-kbps communication link is proposed. The system comprises a power channel and a data transmission channel. The power channel increases the transmission distance by means of a relay coil. The data channel utilizes the coupler that is shared with the power channel, without any additional communication coils. All coils are tapped to extract a smaller inductance for transmitting data and a LCCL circuit is added to the data transmission channel to isolate the interference of each other. In addition, a new circuit topology is used in the relay coil to reduce data attenuation. To achieve a high data rate, the system uses the frequency shift keying (FSK) modulation and coherent demodulation. A 13.69W multi-relay SWPDT prototype with 100-kbps communication and 15cm transmission distance is presented to demonstrate the proposed system.
