直(zhi)流(liu)(liu)穩(wen)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源(yuan)可以(yi)分為兩類：線性穩(wen)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源(yuan)和開關(guan)穩(wen)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源(yuan)。直(zhi)流(liu)(liu)穩(wen)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源(yuan)調試4個步驟(zou)1、直(zhi)觀(guan)檢查(cha)(cha)整機(ji)安(an)(an)裝電(dian)(dian)(dian)(dian)(dian)路后，請仔細檢查(cha)(cha)組(zu)件是否安(an)(an)裝錯誤或缺(que)失，檢查(cha)(cha)焊(han)(han)點是否使用了錯誤的(de)焊(han)(han)料(liao)(liao)，虛擬焊(han)(han)料(liao)(liao)，銅焊(han)(han)，連(lian)續焊(han)(han)接(jie)等(deng)。2、靜(jing)態電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)測量經(jing)過適當的(de)外觀(guan)檢查(cha)(cha)后，在接(jie)通電(dian)(dian)(dian)(dian)(dian)源(yuan)后測量靜(jing)態參數。由于變(bian)壓(ya)(ya)器的(de)次(ci)級(ji)負(fu)(fu)載(zai)必(bi)須具有一定的(de)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)值，因此直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)值約為200Ω。用萬(wan)用表電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)文件檢查(cha)(cha)電(dian)(dian)(dian)(dian)(dian)源(yuan)插(cha)頭。如果測得的(de)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)值小于次(ci)級(ji)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)的(de)值，則(ze)次(ci)級(ji)負(fu)(fu)載(zai)會短(duan)路。3、確定電(dian)(dian)(dian)(dian)(dian)源(yuan)安(an)(an)全檢查(cha)(cha)關(guan)鍵(jian)組(zu)件，4、測量輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)。直(zhi)流(liu)(liu)穩(wen)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)效率較高(gao)，能夠減少能源(yuan)的(de)浪費和熱量的(de)產(chan)生。
