摘　　要：为提升智能手机充电速度,缩短充电等待时间,改善目前智能手机续航能力低下的问题,设计了一种能满足快充技术标准的反激式开关电源。描述了系统各关键电路模块和器件(如变压器、RCD吸收电路及开关器件)的设计过程,给出了系统电路原理图,制作了实验样机,并对实验样机进行实际测试。测试结果表明:该电源纹波小、环路响应快、稳压性能优良。同时该系统具有体积小、重量轻、使用元器件少、电路结构紧凑等诸多优点。In order to promote the smart-phone charging speed, to shorten the waiting time for charging and to improve their battery life, a new kind of flyback mode switching power supply was designed which can satisfy the quick charge technology standard. The design of the key circuit modules （such as RCD circuit） and devices （such as transformer, and switching devices） were described, and the schematic diagram of the system was given, and the prototype was developed, and a actual test of the system was made. The test results show that the power supply is characterized by small ripple, fast loop response and good steady. Also, it has many other advantages such as small in size, light in weight, less in the components used, and compact in circuit structure and so on.
