Abstract：To solve the problem of power and data parallel transmisson simultaneously in wireless power transfer system for rotating mechanism，a paralel transmisson method of power and signal based on dual-channel mode was proposed. Based on analyzing the power and signal transmisson mechanism in dual-channel mode，a mutually decoupled power and signal transmissioncoilis designed.The power transmission is based on the induction coupling technologyof series-none （SN）topology，and the signal transmision is basedon the amplitude modulation mode，combined with the envelope demodulation technology，realizing thetwo-way signal transmission.Experimental results verify the efectivenessof the proposed method，the power signal transmission channels do not interfere with each other， and the signal transmission error rate is zero.
