摘　　要：随着科技的快速发展,微电机得到越来越多的应用,因此要求驱动IGBT的开关电源具有轻便、高稳定性和高安全性等工作特点。由于反激式开关电源具有电路简单,输入电压范围较宽,体积小等优势,因此被广泛应用于电源的设计中。主要介绍一种利用UC3844集成芯片设计的双管反激式多路输出电源,利用光耦PC817和TL431组成反馈电路,实现电路设计。With the rapid development of technology, micro-motors get more and more applications, thus requiring the driver IGBT switching power has the characteristics of lightweight, high stability and high security. Since flyback switching power can provide a simple circuit, wide input voltage range, small size and other advantages, it is widely used in the power supply design. Two-transistor multiple output flyback converter was designed with UC3844 as integrated chip, and the opt coupler PC817 and TL431 as feedback circuit.
