摘　　要：磁耦合谐振式无线能量传输技术主要是由谐振频率相同的发射线圈和接收线圈构成,在近距离范围内,当工作频率等于发射和接收线圈的谐振频率,线圈之间通过磁场耦合谐振的作用完成能量的传输,是电力传输领域的一个全新的技术方向。在本文中,磁耦合谐振无线能量传输系统由印制在两块FR-4基板上的微带线圈组成,且谐振频率为13.56 MHz的微带线圈分别印制在每块基板的两面。根据FITD(Finite-Integral Time-Domain)算法对磁耦合谐振无线能量传输系统模型进行仿真与分析,在13.56 MHZ的频率下,磁耦合谐振无线能量传输系统的传输效率最大可达到64%。在构建无线能量传输平台后,通过实验测得传输效率可以达到54%。Magnetic-coupling resonant wireless power transmission technology is mainly composed of the transmitter coil and receiver coil with the same resonant frequency, in the near range, when the operating frequency is equal to resonant frequency of the transmission and receiving coil, the coil make power transmission through the magnetic field coupling, what is a new technology direction in the power transmission fie ld. In this paper,the mag_ netic-coupled resonant wireless power transmission system consists of microstrip coils printed in FR-4, and micro-strip coil with 13.56 MHz is printed on the top and bottom layers of the substrate. According to the FITD （ Fi-nite-Integral Time- Domain） algorithm, the magnetic coupling resonant wireless power transmission system is simu- lated and analyzed. At the 13.56 MHZ, the transmission efficiency of the magnetic-coupled resonant wireless power transmission system can reach 64%. In the construction of wireless power transmission platform, experimental measurement of transmission efficiency can reach 54%.
