對(duì)于很多人來說，對(duì)于電源適配器的概念只停留在充電器的階段，但實(shí)際上電源適配器是一種變壓器，被大量應(yīng)用在充電器上。對(duì)于電源適配器不熟悉的人往往需要面對(duì)的，是采用哪種電源適配器來進(jìn)行充電 </p> <p> 電源適配器的參數(shù)多種多樣，因此并不能隨意使用適配器來進(jìn)行充電。在選擇電源適配器之前，首先要確定三個(gè)適配條件 </p> <p> ①適配器的接口與設(shè)備匹配 </p> <p> ②輸出電壓必須與負(fù)載的額定輸入電壓相同，或者在負(fù)載)可承受的電壓范圍，否則，可能燒毀負(fù)載 </p> <p> ③電源適配器的輸出電流應(yīng)等于、大于負(fù)載的電流，以提供足夠的電力 </p> <p> 下面就來對(duì)上述的三條適配條件進(jìn)行分析 </p> <p> ①不匹配的接口在沒有專業(yè)知識(shí)的情況下千萬不要亂插，否則會(huì)發(fā)生危險(xiǎn) </p> <p> ②對(duì)于為什么需要電壓一致，從原理上講是這樣的——電壓不足，不足以驅(qū)動(dòng)負(fù)載，電池?zé)o法正常充電 </p> <p> ③對(duì)于為什么需要這樣的電流配置，這要涉及到電路的原理，大家都知道電源是有內(nèi)阻的，內(nèi)阻越大損耗越大。因此廠家在生產(chǎn)這個(gè)適配器的時(shí)候就會(huì)根據(jù)內(nèi)阻大小，確定空載輸出電壓在一定范圍內(nèi)，而電壓臨界值對(duì)應(yīng)的電流臨界值即為我們看到的電流標(biāo)稱值，電流標(biāo)稱值越大說明適配器帶載能力越好。所以選擇電流略大的適配器不但不會(huì)傷害電池，反而會(huì)讓充電變得更快。廣東數(shù)碼產(chǎn)品電源生產(chǎn)廠家電源內(nèi)部結(jié)構(gòu)簡(jiǎn)介是怎樣的？</p><div

src="http://tyunfile.71360.com/UploadFile/szxskj/637142795371875000/3466336.jpg"></div><p> 像電源適配器這種充電設(shè)備，通常用的時(shí)間長(zhǎng)了，又是難免會(huì)出現(xiàn)一些問題，如出現(xiàn)線路出現(xiàn)故障、電壓不穩(wěn)定等癥狀，那么當(dāng)出現(xiàn)故障的時(shí)候，應(yīng)該怎樣處理呢？***新賽電源科技就來簡(jiǎn)單為大家介紹一下處理方法吧。 </p> <p> 1、首先我們可以根據(jù)指示來判斷情況，可以看電源適配器指標(biāo)燈，如果指示燈亮，一般認(rèn)為從電源到適配器之間沒有問題，必須保證是指示燈本身沒壞。 </p> <p> 2、電源線盡量避免弄斷內(nèi)部電纜形成斷路。如果外置電源不供電，這時(shí)可以插上電池試試，如果機(jī)器可以正常啟動(dòng)，就有可能是電源線或者適配器有問題。然后用萬用表檢測(cè)，查明電源線是否有問題，以簡(jiǎn)化維修難度，不要一開始就嘗試打開電源適配器外殼。打開電源適配器外殼的難度真的是太大了。 </p> <p> 3、如果原裝適配器有問題，無法維修或者來不及維修，可以先使用其他適配器替代，只要輸出電壓和功率大致相當(dāng)即可。筆記本電腦內(nèi)部還有穩(wěn)壓電路撐著，不要太過于擔(dān)心輸出電壓不匹配的問題。 </p> <p> 4、曾經(jīng)在網(wǎng)上看見有朋友提到適配器出現(xiàn)問題燒壞電腦主板，估計(jì)這種情況是很罕見的，如果有，筆者估計(jì)是筆記本電腦內(nèi)部的穩(wěn)壓電路損壞。 </p> <p> 5、電源適配器生產(chǎn)廠家檢查電容電阻電感有無問題，如電容出現(xiàn)鼓包，建議及時(shí)更換，以免留下隱患。 </p> <p> <br /> </p> <p> <br /> </p><p> PFC電路： </p> <p> PFC的英文全稱為“Power Factor Correction”意思是“功率因數(shù)校正”。功率因數(shù)指的是電源對(duì)電網(wǎng)供給的電能的利用效率。功率因數(shù)越高表示其對(duì)電網(wǎng)電能的利用率越高。功率因數(shù)的高低跟咱們自家電費(fèi)無關(guān)，只是提升電網(wǎng)供電的利用率。PFC目前有主動(dòng)式PFC，被動(dòng)式PFC和交錯(cuò)試PFC。 </p> <p> 被動(dòng)式PFC： </p> <p> 低端電源常用，特點(diǎn)是PFC電感**固定在電源殼上。 </p> <p> **電源常用的交錯(cuò)試PFC。通常挨著大電容。 </p> <p> 跟一般主動(dòng)式PFC一個(gè)不同的是，一般的主動(dòng)式PFC是一個(gè)電感。交錯(cuò)試的是兩個(gè)相同相鄰的電感而已。 </p> <p> <br
