直流穩(wěn)壓電源設(shè)計及其串聯(lián)應(yīng)用

摘要：介紹了直流穩(wěn)壓電源設(shè)計環(huán)節(jié)中存在的實際問題及處理辦法，并分析了直流穩(wěn)壓電源順串和反串的情況，得出穩(wěn)壓電源順串時能正常工作而反串時穩(wěn)定輸出電壓比較小的電源不能正常工作的結(jié)論。 敘詞：直流穩(wěn)壓電源；順串；反串 Abstract：The thesis described a few teaches，several actual problems and the methods to　analysis and　handle the problems in the design of the direct voltage-stabilizing source．And this paper analyzes the specific circuits of the regulated power supply both in succession and in reverse，drawing a conclusion that the regulated power supply can work properly when connected succession and the regulated power output voltage can’t work properly　when connected in reverse， and finally points out considerab1e attention should be paid in the actual use lest wrong conclusions be made． Keyword：regulated power supply；connected in succession；connected in reverse
