Aimed at the signal reverse transmission optimization problem of power and signal synchronous transmission for the inductively coupled power transfer(ICPT)system

on the basis of exhaustive analysis of the existing literatures

this paper proposes a topology of power and signal reverse synchronous transmission realized by signal parallel injection and serial pickup

and the design method of corresponding parameters is presented. The resonant inductance of ICPT system is considered in the transmission circuit of carrier signal

which can enhance signal emission intensity. And the signal reception intensity is enhanced by the frequency selection smoothing and the current amplification of the LC resonant circuit. The modeling analysis and optimal design of topology parameteres are carried out based on the AC impedance analysis method. Finally

the reliability and validity of the proposed topology and parameter design method have been verified by the simulation and experimental results.
