摘　　要：针对感应耦合电能传输(CPT)系统中的信号传输问题,提出一种基于能量通道的数字信号传输方法。该方法通过切换谐振逆变器开关管的软开关周期来对数字信号进行调幅调制,电能接收端在通过功率调节单元接收电能的同时,提取调制信号特征并进行信号复原,在不改变感应耦合电能传输系统主电路拓扑结构的情况下,实现了传输数字信号。介绍了信号传输原理,分析了功率与信号混合传输特性,以及和信号传输效率之间的关系,并进行了实验验证。According to the signal transmission’s problem in inductive coupled power transfer system,a novel dig-ital signal transmission method based on energy channel is proposed in this thesis.This method is to change the res-onant converter soft-switching period to modulate its digital signals,while the electrical energy sink was received through power regulation unit,extracting the characteristic of modulation signal and performing signal restoring.This method will transfer digital signals in the condition of keeping the inductive coupled power transfer system un-changed.This thesis analyzes a fundamental principle of signal transmission method.The experiment verified that this kind of signal transmission has many advantages on its reliability and it has wide applications in the ICPT sys-tem.
