摘　　要：基于磁耦合谐振原理,采用平板磁心能量传输结构,可实现家用电器无尾化,从而避免插电式充电所带来的安全隐患.本文提出的无线能量传输系统采用一次侧加磁心,二次侧不加磁心的不对称结构,一方面实现了高功率、高传输效率的无线充电过程;另一方面减小了二次侧的尺寸、体积和重量.首先,本文建立了系统磁耦合谐振模型并优化了谐振参数;其次,仿真得到一、二次侧之间的空间耦合系数分布曲线;最后,通过搭建系统硬件平台,实现了60～150mm距离的无线能量传输,传输功率为700W,传输效率最高可达80％.Based on the principle of magnetic resonance,tail-free household appliances can be obtained by using the energy transmission of the fiat magnetic with a core to avoid security risks brought by the charging means of plug-in.The wireless energy transfer system associated with this paper is based on the structure of a primary winding with a magnetic core and a secondary winding without a magnetic core.A high power and high transfer efficiency in the wireless charging process and a reduced secondary in the dimension,volume and weight are achieved by using the system.Firstly,a magnetic coupling resonant model is established and the resonant parameters are optimized.Then a distribution curve of a coupling coefficient is obtained via the simulation.Finally,a wireless transfer distance of 60 millimeter to 150 millimeter,an output power of 700W,and transfer efficiency of up to 84.5％ are achieved via the establishment of a hardware experimental platform.
