串聯(lián)型穩(wěn)壓電源的電路認識串聯(lián)型穩(wěn)壓電路屬直流穩(wěn)壓電源中的一種，其實是在三端穩(wěn)壓器出現(xiàn)之前比較常用的直流供電方法，在三端穩(wěn)壓器出現(xiàn)之前，串聯(lián)穩(wěn)壓器通常有OP放大器和穩(wěn)壓二極管構成誤差檢測電路，如下圖，該電路中，OP放大器的反向輸入端子與輸出電壓的檢測信號相連，正向輸入端子與基準電壓Vref相連，Vs=Vout*R2/(R1+R2).由于放大信號ΔVs為負值，控制晶體管的基級電壓下降，因此輸出電壓減小在正常情況下，必有Vref=Vs=Vout*R2/(R1+R2)，調整R1，R2之比可設定所需要的輸出電壓值。圖中所示只是這也是三端穩(wěn)壓器的基本原理，其實負載大小可以可以把三極管換成達林頓管等等，這種串聯(lián)型穩(wěn)壓電路做組成的直流穩(wěn)壓電源處理不當，極易產生振蕩?，F(xiàn)在沒有一定模擬功底的工程師，一般現(xiàn)在不用這種方法，而是直接采用集成的三端穩(wěn)壓電路，進行DC/DC轉換電路的使用。 ?01984-2454-0001
