摘　　要：探索了在较低频率下多接端、加中继和隔磁材料3种耦合结构下提高谐振耦合系统电能传输效率的可行性。实验表明这些方法均可有效提高系统整体传输效率,最后应用上述方法构建综合系统,综合系统的效率可以达到85.4%。This paper studied the effects of multiple receiver, intermediate coil and magnetic insulating material on the power transfer efficiency. Experimental results showed that these methods all can effectively improve the overall system performance. The integrated system efficiency was 85.4% when these methods was used to build the integrated system.
