摘要
为了使电源具有更好的使用效率和稳定性,文中设计了一种基于UC3842的多路输出型开关电源系统。文中分析了所使用芯片的选择原因,以及电源中主要模块的需求、原理。通过在特定软件上对所设计电源进行仿真,仿真结果表明,该开关电源各路输出稳定,误差<1%(±12 V)、2%(±5 V);且工作效率得到了大幅提升,符合设计要求。
In order, a multi output switching power supply system based on UC3842 is designed for higher efficiency and stability. The reasons for choosing the chips and the requirements and principles of the main modules in power supply are analyzed. Simulation using specific software show that the switch is stable under various power outputs with an error 〈 1% （ ＋ 12 V） and an error of 2% （ ＋5 V） ; the work efficiency is also significantly improved.
