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.
