基于推挽拓扑的非接触充电系统设计

Design of contactless charging system based on push-pull topology

由于各种充电终端的需求不同,各式各样的充电设备出现在人们的生活中。各种充电线缆错综复杂,造成了很多麻烦。基于自振荡推挽式逆变电路设计出非接触式充电系统。它能够直接对各种不同充电终端进行无线充电,消除了各种连接线缆。对非接触充电系统的逆变电路、谐振网络和发射板进行了分析和设计。并以一种手机充电器为例进行实验验证以证明其有效性。

There are more and more charging equipment available now due to the needs of charged terminal of storage batteries.The complexity of a variety of charging cables can cause great trouble.The contactless charging system designed in this thesis was based on push-pull topology,which could charge the different kinds of charged terminal directly without cables.In this paper,the inverting circuit,resonant network and the transmittal panel of the contactless charging system was analyzed and designed.The validity of the proposed system was proved by the experiment involved in mobile phone battery charger as an example.
