摘要： 为了解决金属环境条件下的无线供电和信号传输需求，提出了一种基于电容耦合方式的无线能量和信号并行传输方案。通过建立E类放大器的数学模型，分析电容耦合系统的传输特性和阻抗影响机理，设计了适用于E类放大器结构的调制与解调电路，并通过仿真验证了电路的可行性，为CCPT系统从能量传输到信号回传提供了系统性的理论指导。

Abstract: In order to solve the wireless power supply and signal transmission requirements in the metal environment，a wireless energy and signal parallel transmission scheme based on capacitively coupled power transfer is proposed.By establishing the mathematical model of the class E amplifier，analyzing the transmission characteristics and the impedance mechanism of the capacitive coupling system，a modulation and demodulation circuit suitable for the E-class amplifier structure is designed，and the feasibility of the circuit is verified by simulation，which provides theoretical guidance to energy transmission and signal return of CCPT system.

Key words: Wireless power transfer, Capatively coupled , Signal transmission, Class-E power amplifier, Impedance modulation
