電源適配器的幾個常見問題!

　　一(yi)(yi)(yi)、電(dian)源(yuan)適配器(qi)(下(xia)稱電(dian)源(yuan))的標(biao)稱電(dian)壓(ya)和電(dian)流(liu)(liu)代表什么意思?最先，一(yi)(yi)(yi)般電(dian)源(yuan)標(biao)稱的電(dian)壓(ya)，就是(shi)指引路輸出(chu)的電(dian)壓(ya)，也就是(shi)說外邊不接一(yi)(yi)(yi)切負荷，沒有電(dian)流(liu)(liu)輸出(chu)那(nei)時候的電(dian)壓(ya)，因(yin)此(ci)還(huan)可以(yi)了解為，此(ci)電(dian)壓(ya)就是(shi)說電(dian)源(yuan)輸出(chu)電(dian)壓(ya)的限制。

　　針(zhen)對電源(yuan)內部應用了積極穩壓(ya)管的(de)(de)元器件的(de)(de)狀況下，即便(bian)電壓(ya)電壓(ya)有一(yi)定(ding)的(de)(de)起(qi)伏(fu)，其輸出(chu)都是穩定(ding)值(zhi)，像(xiang)目(mu)前市(shi)面上一(yi)般的(de)(de)小變電器，例如mp3播放(fang)器這(zhe)類配的(de)(de)電源(yuan)，假如電壓(ya)起(qi)伏(fu)，該(gai)電源(yuan)的(de)(de)輸出(chu)也不容易隨(sui)著起(qi)伏(fu)的(de)(de)。

　　一(yi)(yi)般來講一(yi)(yi)般電(dian)源適配器(qi)(qi)的(de)真(zhen)實滿(man)載電(dian)壓(ya)也不一(yi)(yi)定(ding)和標稱電(dian)壓(ya)完全一(yi)(yi)致(zhi)，由于(yu)電(dian)子元(yuan)器(qi)(qi)件的(de)特點不太可能完全一(yi)(yi)致(zhi)，因此有一(yi)(yi)定(ding)的(de)偏差(cha)，偏差(cha)越(yue)(yue)小(xiao)，對電(dian)子元(yuan)器(qi)(qi)件的(de)一(yi)(yi)致(zhi)性(xing)規(gui)定(ding)越(yue)(yue)高(gao)，制(zhi)造的(de)成(cheng)本費(fei)就高(gao)了，因此價(jia)錢也就貴(gui)一(yi)(yi)些了。

　　此外，有(you)關(guan)標稱的(de)電(dian)(dian)流(liu)值，不管一切電(dian)(dian)源常有(you)一定(ding)的(de)內電(dian)(dian)阻(zu)，因而當電(dian)(dian)源輸(shu)出(chu)電(dian)(dian)流(liu)的(de)那時候(hou)，會在內部(bu)造成(cheng)壓力降，造成(cheng)倆件事兒，一個(ge)是造成(cheng)發熱量，因此電(dian)(dian)源會熱，另一個(ge)是造成(cheng)輸(shu)出(chu)電(dian)(dian)壓減少(shao)，等于內部(bu)耗費。

　　二、全是一樣標稱電(dian)(dian)壓的(de)電(dian)(dian)源，輸出電(dian)(dian)流不一樣，能否用在同(tong)一臺本子上?

　　電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)一(yi)(yi)樣，輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)不(bu)(bu)一(yi)(yi)樣，能否(fou)(fou)用(yong)(yong)(yong)在同一(yi)(yi)臺本(ben)(ben)子(zi)(zi)上。基(ji)(ji)礎的(de)(de)標(biao)準是(shi)大(da)(da)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源能夠(gou)替代小標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源。估算許多人會那樣想(xiang)(xiang)，感覺大(da)(da)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源會燒毀本(ben)(ben)子(zi)(zi)，由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)變大(da)(da)嘛。事實上電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)多少(shao)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)同樣的(de)(de)狀況下在于負荷，呵呵呵，想(xiang)(xiang)一(yi)(yi)想(xiang)(xiang)初級(ji)中學的(de)(de)物理(li)學就(jiu)知道(dao)。當本(ben)(ben)子(zi)(zi)長時間負荷運行的(de)(de)那時候，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)大(da)(da)點，本(ben)(ben)子(zi)(zi)進到關機的(de)(de)那時候，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)就(jiu)小些(xie)，大(da)(da)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源有充足的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)容(rong)量(liang)。相(xiang)反，許多人用(yong)(yong)(yong)56w的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源替代72w的(de)(de)用(yong)(yong)(yong)起來也沒(mei)有什么(me)難題，緣(yuan)故是(shi)一(yi)(yi)般(ban) 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源適配器(qi)的(de)(de)設(she)計方案留出(chu)一(yi)(yi)定的(de)(de)容(rong)量(liang)，負荷輸出(chu)功(gong)(gong)率(lv)必須低于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源輸出(chu)功(gong)(gong)率(lv)，因(yin)此這類替代在一(yi)(yi)般(ban)應(ying)用(yong)(yong)(yong)上是(shi)行得通的(de)(de)，可是(shi)剩下的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源輸出(chu)功(gong)(gong)率(lv)容(rong)量(liang)就(jiu)非常(chang)少(shao)了，一(yi)(yi)旦你(ni)的(de)(de)本(ben)(ben)子(zi)(zi)接了許多外接設(she)備(bei)，例(li)如(ru)二(er)塊usb固(gu)態盤(pan)，隨后cpu飛速(su)運行，還(huan)有一(yi)(yi)個基(ji)(ji)座(zuo)，上邊來個光驅飛速(su)讀盤(pan)，加上另外給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，估算就(jiu)風險了，要隨時隨地用(yong)(yong)(yong)手(shou)摸下你(ni)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源是(shi)否(fou)(fou)早已能夠(gou)煮蛋了。因(yin)此盡量(liang)不(bu)(bu)要用(yong)(yong)(yong)小電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源替代大(da)(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源。

　　三、一模一樣的(de)設備，他人的(de)電源溫溫的(de)，我的(de)一直很燙，為(wei)何(he)?

　　先不必猜疑(yi)你的(de)(de)(de)電(dian)源不太好(hao)，先看一下你的(de)(de)(de)本子在干嘛，是否像上邊(bian)說的(de)(de)(de)二塊USB固態(tai)盤，CPU飛速(su)運行(xing)，固態(tai)盤瘋狂讀寫能力(li)，光驅飛速(su)讀盤，另外給電(dian)池充電(dian)，高聲放著歌曲，顯示器亮度較(jiao)大(da)，無線網卡(ka)一直在探測(ce)數據信號這些，靈活(huo)運用電(dian)源管(guan)理方法(fa)，依(yi)據每日任務(wu)有效調節本子的(de)(de)(de)工作(zuo)態(tai)度是很(hen)關鍵的(de)(de)(de)。

　　四(si)、電(dian)源標稱電(dian)壓比我的本子充電(dian)電(dian)池電(dian)壓高許多(duo)，不容(rong)易(yi)出事了吧?

　　最先，要了解的是，電源(yuan)給(gei)(gei)本子供(gong)電系統(tong)與充電電池(chi)給(gei)(gei)本子供(gong)電系統(tong)是不一(yi)樣的。

　　充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)供電(dian)(dian)(dian)系統，充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)輸出(chu)是(shi)(shi)純直流電(dian)(dian)(dian)，整潔得很(hen)(hen)，充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)壓(ya)既(ji)不太可能也不用(yong)設計方案得很(hen)(hen)高，鋰(li)電(dian)(dian)(dian)的(de)(de)有機化學特點決(jue)策了(le)一(yi)節鋰(li)電(dian)(dian)(dian)芯的(de)(de)輸出(chu)電(dian)(dian)(dian)壓(ya)只有在3.6V上(shang)下，因此許多(duo)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)全是(shi)(shi)選用(yong)三級串(chuan)連的(de)(de)方法，10.8V也就(jiu)變成很(hen)(hen)時興的(de)(de)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)壓(ya)。一(yi)些充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)標稱值比3.6V的(de)(de)整數倍稍大一(yi)些，例(li)如3.7V或(huo)是(shi)(shi)11.2V這些，實際(ji)上(shang)是(shi)(shi)以便維護充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)。

　　電(dian)(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)，狀(zhuang)況(kuang)就(jiu)繁(fan)雜一(yi)些，最先(xian)必須(xu)對添加(jia)電(dian)(dian)(dian)(dian)(dian)壓(ya)開展進一(yi)步的(de)(de)穩壓(ya)管濾波器，以確保在(zai)電(dian)(dian)(dian)(dian)(dian)源特性不非常好(hao)的(de)(de)狀(zhuang)況(kuang)下平穩工作中，穩壓(ya)管后的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)分為2個(ge)一(yi)部分，一(yi)路(lu)給(gei)本子(zi)工作中供(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)，另一(yi)路(lu)給(gei)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)，給(gei)本子(zi)供(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)的(de)(de)那(nei)一(yi)部分同充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)供(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)的(de)(de)那(nei)時候(hou)同樣，而給(gei)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)的(de)(de)那(nei)一(yi)部分必須(xu)根據充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)回(hui)(hui)路(lu)才(cai)能夠加(jia)進鋰(li)電(dian)(dian)(dian)(dian)(dian)芯上，控(kong)制(zhi)回(hui)(hui)路(lu)能夠很(hen)繁(fan)雜，因此(ci)電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)壓(ya)務(wu)必超(chao)過鋰(li)電(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)壓(ya)才(cai)有充足的(de)(de)工作能力供(gong)貨(huo)給(gei)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)回(hui)(hui)路(lu)的(de)(de)各模塊。最終真實加(jia)進鋰(li)電(dian)(dian)(dian)(dian)(dian)芯上的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)絕不會就(jiu)是你(ni)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源標(biao)稱的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)。放心好(hao)了。
