的(de)(de)(de)設計(ji)一般包括變(bian)(bian)壓(ya)(ya)、整流(liu)、濾(lv)波、穩(wen)(wen)壓(ya)(ya)四個(ge)基本環(huan)節。為了(le)提(ti)(ti)高電(dian)(dian)(dian)源(yuan)的(de)(de)(de)質(zhi)量及其(qi)可靠性，需對電(dian)(dian)(dian)源(yuan)輸(shu)出電(dian)(dian)(dian)壓(ya)(ya)進(jin)行采樣、比(bi)較、放大(da)，并用此誤差放大(da)信號來調節其(qi)輸(shu)入(ru)電(dian)(dian)(dian)壓(ya)(ya)，使得(de)負載變(bian)(bian)化(hua)時(shi)輸(shu)出電(dian)(dian)(dian)壓(ya)(ya)保(bao)(bao)持穩(wen)(wen)定。此外，為了(le)提(ti)(ti)高電(dian)(dian)(dian)源(yuan)的(de)(de)(de)使用安全性能，需設計(ji)簡單可靠的(de)(de)(de)過(guo)壓(ya)(ya)過(guo)流(liu)保(bao)(bao)護電(dian)(dian)(dian)路，防止電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)流(liu)過(guo)大(da)時(shi)損壞負載元件。以下將從(cong)電(dian)(dian)(dian)源(yuan)主(zhu)電(dian)(dian)(dian)路、控(kong)制電(dian)(dian)(dian)路、保(bao)(bao)護電(dian)(dian)(dian)路設計(ji)等3個(ge)方(fang)(fang)面(mian)簡要介(jie)紹直流(liu)穩(wen)(wen)壓(ya)(ya)電(dian)(dian)(dian)源(yuan)的(de)(de)(de)制作方(fang)(fang)法。

主電路部分設計主要包括電源變壓器、整流電路、濾波電路、穩壓電路設計(圖1)。變壓器把高(gao)壓交(jiao)流(liu)(liu)(liu)(liu)電變(bian)為(wei)所需要的(de)低壓交(jiao)流(liu)(liu)(liu)(liu)電;整流(liu)(liu)(liu)(liu)器(qi)把交(jiao)流(liu)(liu)(liu)(liu)電變(bian)為(wei)脈動(dong)(dong)直(zhi)流(liu)(liu)(liu)(liu)電;濾波(bo)器(qi)濾除直(zhi)流(liu)(liu)(liu)(liu)中(zhong)的(de)交(jiao)流(liu)(liu)(liu)(liu)成分;穩壓器(qi)把波(bo)動(dong)(dong)較大的(de)直(zhi)流(liu)(liu)(liu)(liu)電壓變(bian)為(wei)穩定的(de)直(zhi)流(liu)(liu)(liu)(liu)電壓輸(shu)出。
