Abstract This paper proposes an electric-field coupled power and signal transfer technology based on separated circuit loops and gives the system topology, to reduce the crosstalk between power transmission and signal transmission and the complexity of signal circuit loop during the power and signal parallel transfer process. Based on AC impedance method, this paper sets up the math model of system, then gives the expressions of power transmission gain, signal transmission attenuation and power crosstalk, finally proposes a parameter design method. Without changing the power transmission capability, this method reduces the power crosstalk and complexity of circuit through setting up two relative independent power and signal circuit loops and utilizing its own impedance characteristic. Both simulation and experimental results verify the proposed method. The experiment device can realize parallel transmission of power and signal, and the baud rate of signal transmission is between 1.2kbit/s and 115.2kbit/s.

Key words： Electric-field coupled power transfer system power and signal parallel transfer power crosstalk parameter design
