摘　　要：在电能与信号并行传输过程中,为了降低电能传输与信号传输间的相互串扰及信号通道的复杂度,提出一种基于电场耦合式电能传输系统(ECPT)的电能与信号回路分离式并行传输方法,并给出系统的拓扑;基于交流阻抗法建立所述系统的数学模型,并给出电能传输增益、信号传输衰减以及电能串扰的数学表达式,在此基础上给出系统参数设计方法。该方法通过建立相对独立的电能与信号传输回路并依靠其自身阻抗特性,在不改变电能传输能力的前提下可减小电能传输对信号传输的串扰,并降低电路复杂度。通过仿真和实验验证了该方法的有效性,搭建的系统实验装置可实现在1.2~115.2 kbit/s范围内的电能与信号并行传输。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 1.2 kbit/s and 115.2 kbit/s.
