摘要
低压直流电源在办公、学习和日常生活方面应用极为广泛。设计一种由OV起调的低压直流电源能给工作、学习和日常生活带来极大的便利。用LM317担负输出电压的稳定及调整作用，输出负电压的辅助电源为LM317提供补偿，由此组成0～5V的串联型直流稳压电源，利用Protel99SE辅助可快速完成电路的设计。
Low voltage DC power is widely used in office, study and daily life. Design a low voltage DC power which plays from OV can bring great convenience for work, study and life. The DC regulated power supply（output： 0-5V）in series can be composed of LM317 which stabilize and adjust output voltage and auxiliary power that outputs negative voltage provides com- pensation for LM317, the design of circuit can be quickly completed by Protel99SE.
