摘要
针对感应耦合电能传输(ICPT)系统信号传输存在信号幅值衰减和较强电磁干扰的问题,基于2FSK调制解调方式,提出了一种新型的高速信号传输方法.该方法在不增加系统主电路能量耦合线圈以及不影响主电路正常工作的前提下,实现了高速信号传输.分析了不同结构下主电路信道的阻抗和频域响应特性,确定了调制解调方法及其实现方案,并搭建了系统实验平台,在2.5和1.7 MHz的载波频率下,有效实现了100 kHz脉冲信号的传输.仿真与实验结果验证了所提出的高速信号传输方法的可行性.
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.
