针对MC-WPT能量信号同传系统信号传输速率较低的问题，本文提出了一种基于FSK和ASK混合调制的能量信号共享传输通道传输方法。该方法利用双谐振网络和阻波网络，在系统原、副边之间传输两种不同频率的载波，将传统的ASK调制的单一频率载波变为双频率载波，在ASK调制的同时，混合FSK调制，以此提升系统信号传输速率。文中给出了双谐振拓扑结构和利用双谐振拓扑进行载波混合调制的能量信号同传拓扑，分别建立了能量传输和信号传输的数学模型，最后通过仿真验证了该方法的可行性。
In view of the low transmission rate of MC-WPT energy signal simultaneous transmission system, this paper proposes a transmission method of energy signal shared transmission channel based on FSK and ASK hybrid modulation. In this method, two different frequency carriers are transmitted between the primary side and the secondary side of the system by using the double resonance network and the impedance network. The traditional ASK modulated single frequency carrier is changed into the dual frequency carrier. At the same time of ASK modulation, the FSK modulation is mixed to improve the system signal transmission rate. The dual resonant topology and the simultaneous interpreting topology of energy transmission using dual resonant topology are presented. The mathematical models of energy transmission and signal transmission are established respectively. Finally, the feasibility of the method is verified by simulation.
