中文摘要:
      采用四线圈并联谐振的磁耦合单元,设计了高效率磁耦合谐振式无线传能系统。分析了四线圈磁耦合单元在品质因数和可调节性的优势,结合多物理场仿真软件COMSOL和电路设计软件Multisim,对设计的磁耦合谐振式无线传能系统中磁耦合单元和发射电路单元进行了混合仿真。无线传能系统中源线圈和负载线圈设计为半径9 cm的单匝线圈,发射线圈和接收线圈为半径13 cm的4匝线圈组,发射和接收线圈距离为40 cm(1.5倍线圈直径)。测试表明,该系统的谐振频率为4.78 MHz,系统从直流输入到交流输出的无线传能效率达到了96.7%。
英文摘要:
      A magnetic coupled wireless power transmission system with high wireless transmitting efficiency by utilizing the four-coil parallel resonant unit is proposed. The advantages of the four-coil magnetic coupling unit in the quality factor and adjustability are analyzed. A hybrid simulation method, which integrates the multi-physical simulator COMSOL with the circuit design software Multisim, is utilized to analyze the magnetic coupling unit and the transmitting circuit. For this magnetic coupled wireless power transmission system, its source and load coils are designed to be single-turn coil with a radius of 9 cm, the transmitting and receiving coils are 13 cm four-turn ones, and the distance between the transmitting and receiving coils are 40 cm, correspondingly 1.5 times the coils’ diameter. Measurement results demonstrate, the wireless power transmission system has a resonant frequency of 4.78 MHz, and achieves a high DC-AC wireless transmission efficiency up to 96.7%.
