A novel parallel transfer topology for electric-field coupled wireless power and signal with a parallel-LC isolation module is proposed. In the proposed topology, most of the power crosstalks caused by the power source are isolated by the impedance characteristic of the circuit. Meanwhile, compared with existing systems, the novel system has a wider range of pass-band of the signal channel. Moreover, to enhance the signal transfer baud rate, multiple signal sources are adopted as a mixed-signal in the wider pass-band, and a spectrum analysis based on the fast Fourier transform(FFT)method is conducted to achieve the separation of low frequency crosstalk from multiple compound high frequency signals in the frequency domain. And the demodulation of multiple compound signals with the frequency spectrum crosstalk is achieved. Thus, the anti-interference ability of the system is also strengthened by using this method. The corresponding simulation and experimental results have verified the correctness and effectiveness of the proposed method.
