In order to solve the existing problems of large output voltage fluctuation

poor system stability and so on in power and signal synchronous transmission of inductively coupled power transfer(ICPT)system

a new technology of power and signal synchronous transmission is proposed. This topology is based on ICPT system with fundamental wave and harmonic wave two-path parallel transmission. In the premise of not affecting the system resonance

this technology not only achieves power and signal synchronous transmission with high efficiency but also possesses the stability and non-fluctuation characteristic. The system output voltage is independent of the load by changing the power distribution and control of fundamental energy path and harmonic energy path. The new methodology provides a new idea for the development of the technology. Finally

the experimental data verify the correctness of theory and the feasibility of technology.
