Abstract The monitoring and control of wireless power transfer system are based on signal transmission technology, and the parallel transmission of power and signal technology is based on wireless power transmission channel. A simultaneous wireless power and data transfer system based on double-sided LCC compensation structure was presented in this paper. The system achieved full-duplex signal transmission without affecting the resonance state of the power channel while achieving constant current of the transmitter coil and load of the WPT system. According to the analysis of the impedance and voltage gain of the signal channel, a stable design method of dual-frequency-full-duplex signal communication channel parameters was proposed based on Shannon's second theorem. By adjusting the channel shifting resistance, the signal transmission rate was increased and the signal transmission gain was guaranteed, while the interference of the energy channel to the signal was suppressed. Finally, the proposed structure was verified by simulation and experimental platform, which confirmed that the energy transmission is not affected by the signal channel and reliable and stable full-duplex signal transmission is realized.
