style="text-indent:25px"><p>與線性穩(wěn)壓電源不同的一類穩(wěn)電源就是開關(guān)型直流穩(wěn)壓電源，**大功率補(bǔ)償式穩(wěn)壓器推薦廠家，**大功率補(bǔ)償式穩(wěn)壓器推薦廠家，它的電路型式主要有單端反激式，單端正激式、半橋式，**大功率補(bǔ)償式穩(wěn)壓器推薦廠家、推挽式和全橋式。它和線性電源的根本區(qū)別在于它變壓器不工作在工頻而是工作在幾十千赫茲到幾兆赫茲。功能管不是工作在飽和及截止區(qū)即開關(guān)狀態(tài)；開關(guān)電源因此而得名。開關(guān)電源的優(yōu)點(diǎn)是體積小，重量輕，穩(wěn)定可靠；缺點(diǎn)相對(duì)于線性電源來說紋波較大（一般≤1%VO（P-P），好的可做到十幾mV（P-P）或更小）。它的功率可自幾瓦－幾千瓦均有產(chǎn)品。</p><div

穩(wěn)壓電源是使用電子電路輸出電壓達(dá)到穩(wěn)定目的的電源，有串聯(lián)型穩(wěn)壓電源、并聯(lián)型穩(wěn)壓電源、開關(guān)穩(wěn)壓電源。普通的串聯(lián)穩(wěn)壓電源都安裝電源變壓器，具有輸出電壓穩(wěn)定、波紋小等優(yōu)點(diǎn)，但是電壓范圍小，效率低。并聯(lián)穩(wěn)壓電源輸出電壓特別穩(wěn)定，但是負(fù)載能力很差，只在儀表內(nèi)部做基準(zhǔn)用。開關(guān)電源的調(diào)整管工作在飽和和截止?fàn)顟B(tài)，因而發(fā)熱量小，效率高（75%以上）而且省掉了大體積的變壓器。但開關(guān)直流穩(wěn)壓的輸出的直流上面會(huì)疊加較大的紋波（50mv），在輸出端并接穩(wěn)壓二極管可以改善，另外由于開關(guān)管工作是會(huì)產(chǎn)生很大的尖峰脈沖干擾，也需要在電路中串連磁珠加以改善。

穩(wěn)壓電路穩(wěn)壓電路是指在輸入電壓、負(fù)載、環(huán)境溫度、電路參數(shù)等發(fā)生變化時(shí)仍能保持輸出電壓恒定的電路。這種電路能提供穩(wěn)定的直流電源，廣為各種電子設(shè)備所采用。直流穩(wěn)壓電源的技術(shù)指標(biāo)可以分為兩大類：一類是特性指標(biāo)，反映直流穩(wěn)壓電源的固有特性，如輸入電壓、輸出電壓、輸出電流、輸出電壓調(diào)節(jié)范圍；另一類是質(zhì)量指標(biāo)，反映直流穩(wěn)壓電源的優(yōu)劣，包括穩(wěn)定度、等效內(nèi)阻（輸出電阻）、紋波電壓及溫度系數(shù)等。符合直流穩(wěn)壓電源工作條件情況下，能夠正常工作的輸出電壓范圍。該指標(biāo)的上限是由比較大輸入電壓和**小輸入－輸出電壓差所規(guī)定，而其下限由直流穩(wěn)壓電源內(nèi)部的基準(zhǔn)電壓值決定。
