很多人經(jīng)常把這兩個概念混淆，轉(zhuǎn)換效率和額定功率其實沒一毛錢直接關(guān)系。 </p> <p> 轉(zhuǎn)換效率指的是電源本身對電能的利用率。比如我在使用一個轉(zhuǎn)換效率為百分之八十的電源。電腦內(nèi)部配件消耗是80W，這時候用功耗儀去檢測電源輸入端功耗應(yīng)該是100W。有百分之二十的電量在轉(zhuǎn)換過程中被電源自身損耗掉了。 </p> <p> 而額定功率指的是電源本身能供給電腦硬件多少電。電源銘牌上標(biāo)注的額定功率就是電源的實際輸出能力。各路功率額定多少瓦就能實際輸出多少瓦。但是不能超出電源額定總功率。換句話說，電源額定500W，轉(zhuǎn)換效率百分之八十，假如500W全部供給電腦配件。這時候你檢測輸入電量應(yīng)該是600W。廣東桌面式電源廠家電源適配器，也有叫充電器。</p><div

我們知道，任何的電器、電子產(chǎn)品，在設(shè)計、制造過程中均規(guī)定了電源適配器的工作電壓。在此規(guī)定的電壓下工作時，電子產(chǎn)品在性能、效率、使用壽命等方面，才能達到原設(shè)計的較好指標(biāo)。 </p> <p> 而此規(guī)定的工作電壓，通常稱為電子產(chǎn)品的額定電壓。 </p> <p> 如果實際的電源適配器電壓高于或低于額定電壓某一允許值百分?jǐn)?shù)，為了保證測量或試驗結(jié)果的準(zhǔn)確性。這是對穩(wěn)定電源適配器的要求，不*包含對輸出電壓或電流穩(wěn)定的要求，有的還包含對紋波、噪聲、溫漂、時漂等指標(biāo)的要求。 </p> <p> 為了保證儀器的測量精度。某些精密儀器，例如核磁共振譜儀，要求它的磁場線圈所產(chǎn)生的場強變化小于10-6T。因此，對勵磁電源適配器的穩(wěn)定度和紋波等也提出了很高的要求。 </p> <p> 沒有穩(wěn)定的電源適配器支持，配置再好的電子產(chǎn)品，性能也無從發(fā)揮。而想要得到穩(wěn)定的電力支持，好品質(zhì)的電源是必不可少的。所以，電源適配器對整套系統(tǒng)來說是極為重要的。新賽電源是一家專業(yè)生產(chǎn)電源適配器的廠家，專業(yè)生產(chǎn)好的電源產(chǎn)品給客戶。 </p> <p> <br /> </p> <p> <br /> </p><p> 電源適配器是人們生活中常用的電源轉(zhuǎn)換裝置，電源適配器種類繁多，包括AC/AC和AC/DC電源轉(zhuǎn)換器、充電器等產(chǎn)品。那你知道電源適配器有哪些常見的質(zhì)量問題嗎？***電源適配器廠家就和您說一說! </p> <p> 1、電源適配器過熱 </p> <p> 電源適配器在工作情況下溫升過高是一個常見問題,。電源適配器高溫時要遠(yuǎn)離易燃易爆物品，否則容易引起火災(zāi),如果發(fā)現(xiàn)產(chǎn)品溫升過高，應(yīng)及時停止使用。 </p> <p> 2、該產(chǎn)品在短路過載時存在安全性能隱患。 </p> <p> 在輸出短路、電容器或二極管短路等情況下，電源適配器內(nèi)部損耗急劇增加，導(dǎo)致各部分溫度升高。 </p> <p> 3、產(chǎn)品的標(biāo)記不齊全或者不規(guī)范 </p> <p> 標(biāo)識應(yīng)包含指導(dǎo)用戶正確安裝和使用的重要信息，產(chǎn)品正確標(biāo)識的標(biāo)識應(yīng)確保用戶個人財產(chǎn)的安全。 </p> <p> 4、電源插頭不規(guī)范 </p> <p> 我國規(guī)定家用單相電源插頭有兩種形式：兩級無極接地和兩級接地。電源插頭應(yīng)防止單級插入使用。 </p> <p> 電源適配器是國家3C認(rèn)證的產(chǎn)物，存在質(zhì)量上訴的質(zhì)量問題，主要是缺乏對部分企業(yè)安全標(biāo)準(zhǔn)的***、準(zhǔn)確的理解和理解。此外，為了降低成品的成本和材料，這是造成部分產(chǎn)品不合格的重要原因。 </p> <p> 想買正規(guī)電源適配器，您可以來12年電源適配器廠家新賽電源看看。一般說電源穩(wěn)定不穩(wěn)定，主要還是看電壓穩(wěn)不穩(wěn)定。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

PFC和EMI因為是假電源重災(zāi)區(qū)，所以沉默醬單獨摘出來說一遍。 </p> <p> EMI電路： </p> <p> EMI是Electromagnetic Interference英文縮寫，是指電磁波與電子元件作用后而產(chǎn)生的干擾現(xiàn)象。市電進入電源之后，第1個經(jīng)過的就是EMI電路。它作用就是濾除市電中的高頻雜波，去除干擾。然后把相對純凈的交流電送到整流橋，經(jīng)過整流橋到達PFC電路。 </p> <p> 在單獨電路板上的EMI </p> <p> <span style="font-size:12px;">焊接在電源口上的EMI</span> </p> <p> PCB上的二級EMI </p> <p> 沒有EMI電路的后果是很嚴(yán)重的。220V交流電直接送到整流橋去整成直流電。對電源本身和電腦主板等都是極大的損傷=A=。沒有EMI的電源絕大多數(shù)都是小品牌的山寨電源或者假電源。同時，沒有EMI的電源一般使用的被動PFC也是假的，**是一條導(dǎo)線。深圳新賽電源是國家高新技術(shù)企業(yè)。廣東桌面式電源廠家</p><p

1.手機充電器是由一個穩(wěn)定電源加上必要的恒流、限壓、限時等控制電路構(gòu)成。手機充電器包括有無線充電器、車載充電器等。主要用于給手機、平板電腦等與手機接口一樣的設(shè)備充電。 </p> <p> 2.車載充電器是指通過汽車電瓶供電的車載配件，其一般具有過載保護，短路保護，高壓輸入保護，高溫保護，四重安全保護功能，確保能安全使用。 </p> <p> 3.電腦充電器也稱為筆記本電源適配器，是小型便攜式電子設(shè)備及電子電器的供電電源變換設(shè)備，一般由外殼、變壓器、電感、電容、控制IC、PCB板等元器件組成。 </p> <p> 除了這三種充電器以外，我們?nèi)粘Ｉ钪谐Ｒ姷倪€有路由器充電器、加濕器、按摩儀等小家電充電器各種充電器。 </p> <p> <br /> </p> <p> <br />
