基于低成本MCU的无线充电发射端设计
|
摘要
随着智能手机的不断更新换代,设备功耗越来越大,充电次数也逐渐增多,传统的充电器和电线使充电受到较大约束,这给无线充电技术的发展提供了契机。介绍了无线充电系统的工作原理及系统的基本结构,并结合项目需求选取了基于Qi协议的无线充电方案并进行研究。最终该系统基于低成本的MCU,实现异物检测(FOD)、Qi协议传输等功能,实现了5 W无线充电的低成本应用。
With the continuous updata of smart phones, the power consumption of devices is getting larger and larger, and the charging frequency is also increasing gradually. Traditional chargers and wires restrict the charging, which provides an opportunity for the development of wireless charging technology. This paper mainly introduces the principle of the wireless charging system and the basic structure of the system, and selects and studies the wireless charging scheme based on Qi protocol according to the project requirements. Finally,the system which is Based on the lowcost MCU, implements the functions of FOD and Qi protocol transmission and the realizes lowcost application of 5 W wireless charging.
