  • In view of magnitude attenuation and electromagnetic interference in the signal transmission of the inductively power transfer (ICPT) system, a new high-speed signal transmission method based on 2FSK is proposed. This method can achieve high-speed signal transmission without increasing the number of coupled coils in main circuit and affecting normal system operation. Firstly the characteristics of channel impedances and frequency responses under different main circuit structures were analyzed; then the modulation and demodulation mode were determined. Finally a circuit experiment system was built. With carrier frequencies of 2.5 MHz and 1.7 MHz, a 100 kHz pulse signal transmission was achieved. The agreement of simulation and experimental results verifies the feasibility of this method.
