摘要
针对利用双向感应耦合电能传输(Inductively Coupled Power Transfer,ICPT)系统的能量通道实现信号交互传输时产生信号与系统输出电压间的互扰谐波问题,采用双LCC谐振补偿网络,基于串联注入拾取式的频移键控信号载波调制方式,给出一种双向ICPT系统能量与信号同步传输方法.选取4 MHz和5 MHz的低频载波信号和高频载波信号,采用状态空间模型及交流阻抗法分析能量与信号之间互扰问题,利用Matlab/Simulink仿真平台搭建双向ICPT系统能量与信号同步传输仿真模型.仿真结果表明,系统可实现最大效率的能量双向传输以及信号的零误码率传输,信号与能量在同步传输时互扰较小,通过系统波特图的分析验证了选取频率点的有效性.
The system has the problem of mutual interference and harmonics between the signal and the system output voltage,when the energy channel of the bidirectional Inductively Coupled Power Transfer(ICPT)system is used to achieve signal interactive transmission.This paper,based on the series injection pick-up frequency-shift keying signal carrier modulation method,presents a bidirectional ICPT system’s energy and signal synchronization transmission method,which uses a dual LCC resonance compensation network.Low-frequency carrier signal and high-frequency carrier signal are selected as 4 MHz and 5 MHz.The problem of mutual interference between energy and signal is analyzed using state space model and AC impedance method.A simulation model for the simultaneous transmission of energy and signal of the bidirectional ICPT system is built through the Matlab/Simulink simulation platform.The simulation results show that the system can achieve the maximum efficiency of bidirectional transfer of energy and zero error rate transmission of signals.The interferences between energy transfer and data transmission are quite small.The validity of the selected frequency points is verified by analyzing system BODE diagram.
