[Abstract]
To solve the problem of power and data parallel transmission simultaneously in wireless power transfer system for rotating mechanism, a parallel transmission method of power and signal based on dual-channel mode was proposed. On the basis of analyzing the power and signal transmission mechanism in dual-channel mode, a mutually decoupled power and signal transmission coil is designed. The power transmission is based on the induction coupling technology of SN topology, and the signal transmission is based on the amplitude modulation mode, combined with the envelope demodulation technology, realizing the two-way signal transmission. Experimental results verify the effectiveness of the proposed method, the power signal transmission channels do not interfere with each other, and the signal transmission error rate is zero.
