Abstract
In this paper, a Simultaneous Wireless Power and Information Transfer (SWIPT) system between multi-transmitter and multi-receiver through the same channel is designed. To reduce cross coupling between resonators, we add a switch to the relay resonators and control the relay switch according to the feedback information of the receiver. We establish a general system model, which is applicable to several transmitters and several receivers, then we simulate the performance of power transfer efficiency and bit error rate of the system in different relay state. In the best case, the measurement of the MCR-SWIPT system gives power transfer efficiency of 63% and BER of 2.1% at 6.78 MHz at a distance of 20 cm. The experiment results demonstrate that data signals can be transmitted between multi-transmitter and multi-receiver without affecting the power transmission. Moreover, magnetic field distribution is reshaped by controlling the relay resonators’ switch, facilitating performance optimization.
