將得到穩(wěn)壓精度和性能符合標(biāo)準(zhǔn)的直流電壓再經(jīng)過濾波器；進(jìn)行濾波后既得到我的所需要的輸出直流電為了得到我的所需要的輸出電壓值或穩(wěn)流電流值，

我們還需要對輸出的電壓值和電流值進(jìn)行取樣檢測并將其傳送到控制/保護(hù)電路，

控制/保護(hù)電路將檢測到的輸出電壓值錢和電流值與電壓/電流設(shè)定電路所設(shè)定的值進(jìn)行比較分析后驅(qū)動(dòng)預(yù)穩(wěn)壓電路和大功率調(diào)整管使直流穩(wěn)壓電源能輸出我們所設(shè)定的電壓和電流值，

同時(shí)當(dāng)控制/保護(hù)電路檢測到異常的電壓或電流值等情況下

將啟動(dòng)保護(hù)電路使直流電源進(jìn)入保護(hù)狀態(tài)。

直流電源的技術(shù)指標(biāo)

　　直流電源的技術(shù)指標(biāo)分為兩種：一種是特性指標(biāo)，包括允許輸入電壓、輸出電壓、輸出電流及輸出電壓調(diào)節(jié)范圍等；另一種是質(zhì)量指標(biāo)，用來衡量輸出直流電壓的穩(wěn)定程度，

包括穩(wěn)壓系數(shù)（或電壓調(diào)整率）、輸出電阻（或電流調(diào)整率）、

紋波電壓（周圍與隨機(jī)漂移）及溫度系數(shù)。
