Abstract
In the wireless power transmission application systems, the signal transmission is important. However, the synchronous transmission of power and signal by the same coil is the primary problem for applying the wireless transmission technology in industry. It is also one of the hot topics of wireless power transmission technology. Aiming at solving this problem, a power and information synchronous transmission method was presented using amplitude shift keying (ASK) modulation and demodulation based on wireless power transmission with four-coil structure. Then the circuits for modulation and demodulation as well as synchronous transmission coil were designed. Finally, the experimental results have verified the proposed method.
