The 感应式非接触电能传输(inductive contactless output and impedance features of the LCL circuit were analyzed, when the ratio of inductance equals to 1, the power transfer ，ICPT) 的基本原理是利用电磁感应将 resonance frequency is independent on the load, this property is 电能转化为磁能，在比较大的气隙内通过磁场将能 useful in ICPT. The structure of a movable ICPT system with 量从耦合线圈的原边传递到副边。ICPT 不需要导 multi-loads was introduced and its equivalent circuit model 体的直接接触，不会产生火花，绝缘效果好，没有 was presented, according to the analysis of the equivalent 裸露导体，安全性能高，维护成本低。ICPT 在一 circuit, an independent control method was put up, and the 些特殊场合的供电系统中有广泛的应用，比如在水 resonance frequency of compensation circuit should be independent on the load, so the load can be changeable. The 下和易燃易爆环境中移动设备的供电系统中采用 design methods of the
