无线充电器的设计与仿真

The Design and Simulation of Wireless Charger

文章设计利用电磁感应的原理,能量通过磁场从发送器传输到接收器,多个接受设备可以共用同一个充电器,从而取代目前的电源适配器。文章设计了无线充电系统的软硬件,提供了运用555芯片设计的简易型充电器和运用单片机设计能自动识别负载是否完成充电的数显式充电器。无线充电器不仅使充电更加便捷,也避免因充电器接口不统一而造成资源浪费,提高能源利用率。经过实验仿真验证了方案的可行性,可满足实际需求。

The design is based on the principle of electromagnetic induction. Energy is transmitted from the transmitter to the receiver through the magnetic field. Since different devices can share the same charger,therefore,it is possible to replace the current power adapter. In this article both the software and hardware were designed for the wireless charging system. By using 555 chip,a simple charger was made,and by using single-chip,a digital charger was designed which could automatically identify whether the load had completed the charging. The wireless charger not only made charging more convenient,but also avoided the waste of resources due to different charger interface disunity. Our experimental simulation has proved the feasibility of the program and requirements of the practical application have been met.
