摘　　要：直流稳压源在日常生活和教学实验环节中有着非常广泛的应用。多输出直流稳压源以其输出范围可调的优点,成为直流电源设计的热点。为了设计一个便携实用的多输出直流稳压源,利用我国市电电压作为输入,经过变压、整流和滤波,再利用电压转换芯片分别产生±5、±12以及可调的-12～+12V的输出电压,多路可以同时工作,每路的最大输出电流为1.5A。与同类产品相比,本设计结构简单,层次清晰,能够满足对同一种直流电源不同的输出要求。DC regulated power supply has been widely used for daily life and experimental teaching. Multi-output DC reg- ulated power supply has an advantages of changeable output, which has attracted attention from designers of power sup- ply. At the present work,a portable and practical Multi-output DC regulated power supply was proposed. Its allowable in- put voltage is 220 V, and output voltage ranges at -12-＋12 V. Moreover, multiplex output with 1.5A maximum output current of each way simultaneously works. What is more,this designation can meet various requirements for all sorts of power source outputs.
