【正文】 ply general from power transformer, mutate the an electric circuit and steady ,press the electric circuit the lowpressure alternate current that electric voltage need when changing into in exchanges in electricity in the machine change into the direct current to the alternate the an empress, it is steady to press the machine change into the stable direct current electric voltage exportation to the unsteady direct current electric voltage again. The main adoption in this design is steady to press the slice constitutes to gather steady to press the electric circuit, passing to change to press, mutating, the wave steady ran over the distance an alternate current, change into the stable direct current, and realizes the electric voltage output 177。12V and can be adjustable in the +3~+18 Vs. Key words: change to press 。steady press 1 緒論人類社會(huì)已經(jīng)進(jìn)入信息化時(shí)代，信息社會(huì)的發(fā)展離不開電子產(chǎn)品的發(fā)展。由于不同的電子產(chǎn)品可能需要不同的電源，做可調(diào)電源就會(huì)使需不同電源的電子產(chǎn)品得到與它匹配的電源，從而使得它能正常工作，使它的工作效率達(dá)到最高。 2 設(shè)計(jì)的技術(shù)指標(biāo)及要求根據(jù)技術(shù)要求和已知條件，完成對(duì)多路輸出直流穩(wěn)壓電源的設(shè)計(jì)、裝配與調(diào)試。12V/1A，177。② 選擇電路方案，完成對(duì)確定方案電路的設(shè)計(jì)。（選做：用PSPICE或EWB軟件完成仿真）③ 安裝調(diào)試并按規(guī)定格式寫出課程設(shè)計(jì)報(bào)告書。3 選定方案的論證及整體電路的工作原理 選定方案的論證根據(jù)設(shè)計(jì)要求，輸出的最大電源為+18V/1A，因此的輸出的最大功率為18W，為了輸出正負(fù)電壓，所以最好應(yīng)該選擇20W/177。因?yàn)檫x擇了三端輸出的變壓器
