In this paper, a 16 stages digital controlled DC stabilizedvoltagesource based on LM317 is designed. Selection and realization of the adjustable resistance in this source is introduced.
In the end, it discussed the protection system of DC voltage-stabilizedsource and put forward the principles of protection system design and the measure of the whole machine protecting.
最后讨论了稳压电源的保护系统，提出保护系统设计的原则和整机保护的措施。
