摘　　要：为了方便手机等小型电子设备的充电,讨论了无接触电能传输原理,采用了提高系统工作频率、电容补偿以及电路拓扑3种手段,实现了对小型电子设备的稳定、高效充电。通过采用平面电感代替传统的带铁芯的松耦合变压器进行了电磁能量的传输,实现了多负载工作。不仅完成了单部手机充电系统的制作,而且将该理论运用到充电平台的设计上。研究结果表明,通过对手机的简单改造,可以省去手机充电器实现无接触充电,简单便捷。Aiming at charging mobile phone and other small electronic device, the contactless power transmission principle was discussed . Three measures were taken to achieve stable and high efficiency charging for small electronic equipment including improving the system working frequency, capacitance compensation and circuit topology. The planar inductor was used to be instead of the traditional belt core of the loosely coupled transformer in electromagnetic energy transmission to realize the multi-load operation. The results indicate that it not only completes a single mobile phone charging system, but also uses the theory on the charging platform design. Based on a simple modification of mobile phone, tbe results show that the charger can be omitted through non-contact charging, which is simple and convenient.
