電源適配器又叫外置電源，是小型便攜式電子設(shè)備及電子電器的供電電壓變換設(shè)備，具有電壓轉(zhuǎn)換功能，其常見(jiàn)的產(chǎn)品名稱有電源適配器、充電器和電源供應(yīng)器等 </p> <p> 電源適配器一般由外部絕緣外殼和內(nèi)部電路器件組成，其與電網(wǎng)電源（市電）的連接方式分為插頭電源線和直插式，其中直插式電源適配器的外殼與插銷形成一體，這種形式也是目前小型便攜式電子產(chǎn)品電源適配器（充電器）中應(yīng)用zui多的情況。 </p> <p> 多年來(lái)，我國(guó)一直對(duì)信息技術(shù)設(shè)備和音視頻設(shè)備用電源適配器產(chǎn)品實(shí)施CCC強(qiáng)制性產(chǎn)品認(rèn)證管理制度，同時(shí)各級(jí)質(zhì)量監(jiān)管部門也在不斷針對(duì)電源適配器產(chǎn)品進(jìn)行監(jiān)督抽檢工作。隨著電子產(chǎn)品日益增多，廣東安防電源多少錢，電源適配器供電的應(yīng)用越發(fā)普及，已形成適用人員多樣性和使用環(huán)境多樣性的特點(diǎn)，加大了產(chǎn)品質(zhì)量安全風(fēng)險(xiǎn)程度。 </p> <p> 而且電源適配器的生產(chǎn)技術(shù)工藝雖已較為成熟，但是技術(shù)門檻不高，廣東安防電源多少錢，成本低廉，缺乏生產(chǎn)質(zhì)量保證能力的中小型企業(yè)的產(chǎn)品不斷涌入市場(chǎng)，致使產(chǎn)品質(zhì)量良莠不齊，總體抽檢不合格率較高。因此，如何提升電源適配器產(chǎn)品的質(zhì)量是我們檢驗(yàn)檢測(cè)機(jī)構(gòu)、監(jiān)管部門以及電源適配器生產(chǎn)企業(yè)，甚至是整機(jī)產(chǎn)品生產(chǎn)企業(yè)共同關(guān)注的問(wèn)題。

AC/DC開(kāi)關(guān)電源適配器芯片（或稱模塊），只要配合一些阻容元件和一個(gè)開(kāi)關(guān)變壓器，就可以做成一個(gè)基本的開(kāi)關(guān)電源適配器。 </p> <p> 普通半橋開(kāi)關(guān)電源適配器的主要工作原理就是上橋和下橋的開(kāi)關(guān)管（頻率高時(shí)開(kāi)關(guān)管為VMOS）輪流導(dǎo)通，首先電流通過(guò)上橋開(kāi)關(guān)管流入，利用電感線圈的存儲(chǔ)功能，將電能集聚在線圈中，然后關(guān)閉上橋開(kāi)關(guān)管，打開(kāi)下橋的開(kāi)關(guān)管，電感線圈和電容持續(xù)給外部供電。 </p> <p> 然后又關(guān)閉下橋開(kāi)關(guān)管，再打開(kāi)上橋讓電流進(jìn)入，就這樣重復(fù)進(jìn)行。 </p> <p> <br /> 廣東外驅(qū)動(dòng)電源制造商其實(shí)真正的充電器與適配器是有區(qū)別的。</p><div style="width:100%;text-align: center;"><img

動(dòng)態(tài)性能指的是電源在負(fù)載大起大落時(shí)候的瞬間的電壓變動(dòng)。這個(gè)包括電壓的變化和電壓的波形。在負(fù)載高低變化的一瞬間，電壓越穩(wěn)定越好，波形越接近一條直線越好。因?yàn)檫@個(gè)測(cè)試目前還沒(méi)有一個(gè)固定的標(biāo)準(zhǔn)。而且一般也遇不到這種情況，所以一般只是作為一個(gè)對(duì)比參考。 </p> <p> 5.保持時(shí)間 </p> <p> 保持時(shí)間指的是突然斷電后，各路電壓正常輸出的時(shí)間，這個(gè)時(shí)間主要是由主電容容量決定的。其主要目的是為了給一些硬件作出應(yīng)急處理的時(shí)間，比如機(jī)械硬盤磁頭歸位，固態(tài)的掉電保護(hù)等等。一般來(lái)說(shuō)主電容容量比較好大于每瓦0.5微法。 </p><p> 電源適配器分為桌面和插墻兩種款式，插墻式電源適配器就是本體可以直接插在插板上或者插座上使用的電源適配器。而桌面式電源適配器就是本體需要放在桌面上的電源適配器。桌面式電源適配器和插墻式電源適配器的區(qū)別還有就是，桌面式電源適配器需要AC線與市電（交流電）連接。 </p> <p> 電源適配器在安防產(chǎn)品、通訊產(chǎn)品、以及小家電類產(chǎn)品和消費(fèi)類電子產(chǎn)品中使用尤為***，特別在便攜類消費(fèi)電子和通訊產(chǎn)品中一般以10W以內(nèi)居多 </p> <p> 一般36W以下多采用插墻式電源適配器，這種電源適配器的特點(diǎn)是不需要AC線材,這樣成本較為節(jié)省、節(jié)約空間，不需要置放電源的臺(tái)面或空間。直接插在插板上也比較安全，有少數(shù)36W以下電源適配器采用桌面式，這種一般是因?yàn)榭紤]到使用產(chǎn)品離AC插板距離較遠(yuǎn)或者因?yàn)殡娫催m配器體積較大，質(zhì)量較重，多口USB電源適配器，為了避免使用上面插的USB產(chǎn)品多而導(dǎo)致插不穩(wěn)的情況。而大于36W的電源適配器就不合適做成插墻式，因?yàn)槠潴w積和重量都較大了，所以36W以上一般采用桌面式 </p> <p> 隨著科技的發(fā)展，以及對(duì)能源愈加緊張、對(duì)能效要求越來(lái)越高，消費(fèi)類電子產(chǎn)品對(duì)電源適配器有高效率、寬輸入電壓范圍的要求，以及銅、鐵和人力成本的增加，這線性變壓器大都逐漸被開(kāi)關(guān)電源適配器所取代。 </p> <p> <br /> </p> <p> <br />
