摘要/Abstract

摘要：

随着无线电能传输技术的发展成熟,其应用范围不断扩大。为了提升系统的鲁棒性,实现高性能的电能传输以及信号传输,越来越多的应用场合要求实现通信功能。系统基于磁耦合谐振无线电能传输技术,针对具体相关的应用场景,设计了能量信号并行传输系统的框架。能量传输补偿拓扑选择LCC-S型结构,并在传统的双线圈能量传输耦合机构中加入了一对特殊线圈作为通信信道,实现了能量信号的并行传输,并从仿真和实验的角度验证了所设计系统的可行性。

关键词: 无线电能传输, 磁耦合谐振, LCC-S型拓扑, 能量信号并行传输

Abstract:

With the development of wireless power transfer technology,its application range is expanding.In order to improve the robustness of the system,to realize high-performance power transfer and signal transfer,more and more applications require the realization of communication function.Based on the technology of magnetically coupled wireless power transfer,the framework of power signal parallel transmission system is designed according to the specific application scenarios.LCC-S structure is selected for power transfer compensation topology.A pair of special coils are added to the traditional power transfer coupling mechanism as communication channel to realize the parallel transfer of power and signal.The feasibility of the system is verified from the point of simulation and experiment.

Key words: wireless power transfer, magnetic coupling resonance, LCC-S resonance compensation topology, power and signal parallel transfer
