Abstract

A magnetically coupled resonant wireless power transmission system which can realize synchronous transmission of energy and information is porposed 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 voltage at both of transmitting and receiving coil changes regularly, and the signal to be transmitted is restored after signal processing,including:detection, filtering, comparison. The simulation results of the proposed circuit show that the scheme is feasible and a communication mode for this system is proposed, which can send the signal correctly.Furthermore, the transmission of the signal has little influence on the power transmission efficiency.

Keyphrases: ASK modulation, FSK control, resonance, synchronous transmission, wireless power transmission
