摘　　要：电动汽车无线充电基于耦合电路的作用通过谐振器将能量由初级侧传递到次级侧,实现能量的无线传输,是研究无线充电系统的关键技术之一,其传输效率受到多个因素的影响。整体的工作效率是绕组结构、耦合效果、工作频率等共同作用的结果,而传输距离的长短也会直接影响传输效率。本文围绕无线电能传输系统的距离特性展开分析,研究距离对电路传输特性的影响。本实验最后得到的传输效率为72%,传输距离为12 cm,完全印证了无线充电谐振耦合理论的分析。Wireless charging is the main purpose of coupled circuit through the resonator transfer energy from the primary side to the secondary side, realize the wireless transmission of energy, is one of the key technology research system, the transmission efficiency is restricted by multiple factors, and the overall efficiency is winding structure, the coupling effect, together with the working frequency, etc . However the transmission distance of increase or decrease will directly affect the transfer efficiency . By analyzing the distance characteristics of wireless charging system in this paper to explore the influencing factors of the distance of circuit transmission characteristics. This experiment finally get transmission efficiency of 72%, transmission distance of 12 cm, fully demonstrated the wireless charging resonance coupling theory analysis.
