摘要：
A magnetically coupled resonant wireless power transmission system which can realize synchronous transmission of energy and data is proposed in this paper. The digital frequency modulation signal is used to control the working frequency of the inverter circuit and change the resonant working state of the transmission system. The envelope of the signal at both of transmitting and receiving coil imply the transmitted data, and the data is demodulated after signal processing, including: detection, filtering, comparison. The simulation results of the proposed circuit show that the scheme is feasible and a frame structure for this system is proposed, which can send the data correctly. Furthermore, the transmission of the signal has little influence on the power transmission efficiency.
