摘　　要：非接触供电系统是一种利用电磁感应耦合理论并结合高频变换技术的新型电能传输技术。通过对非接触供电系统原边中的电流变换进行分析,设计了一种新型LCL网络拓扑结构,实现了方波到正弦波的变换,并构建出恒流电路,使得加载到电缆上的电流不随负载发生变化,在实际工程应用中得到了实现,使用效果良好。Contactless power supply is a kind of new electric energy transmission technique which adopted electromagnetic induction cou- pling theory in combination with high-frequency conversion technique. Via analysis on current transformation at the primary side of contactless power supply system, a new LCL network topology was designed. Square waves were converted to sine waves. Also a stable constant current circuit was constructed to make the current loading on the cable unchanged with loads. This system can be realized in real engineering application with good effectiveness.
