電源適配器的幾個常見問題!

　　一(yi)、電(dian)源適配(pei)器(下稱(cheng)(cheng)電(dian)源)的標(biao)(biao)稱(cheng)(cheng)電(dian)壓(ya)和電(dian)流(liu)代表什么意思(si)?最先，一(yi)般電(dian)源標(biao)(biao)稱(cheng)(cheng)的電(dian)壓(ya)，就(jiu)是指引路輸(shu)(shu)出的電(dian)壓(ya)，也就(jiu)是說外邊不(bu)接一(yi)切(qie)負荷，沒有電(dian)流(liu)輸(shu)(shu)出那(nei)時(shi)候的電(dian)壓(ya)，因(yin)此(ci)還可以(yi)了(le)解為(wei)，此(ci)電(dian)壓(ya)就(jiu)是說電(dian)源輸(shu)(shu)出電(dian)壓(ya)的限制。

　　針對電(dian)源(yuan)內部應用(yong)了積極穩壓(ya)管的(de)(de)元器件的(de)(de)狀況下，即(ji)便電(dian)壓(ya)電(dian)壓(ya)有一定的(de)(de)起(qi)伏，其(qi)輸(shu)出(chu)都是(shi)穩定值，像目前(qian)市面(mian)上一般的(de)(de)小變電(dian)器，例如mp3播放器這類配的(de)(de)電(dian)源(yuan)，假如電(dian)壓(ya)起(qi)伏，該電(dian)源(yuan)的(de)(de)輸(shu)出(chu)也不容易隨著起(qi)伏的(de)(de)。

　　一(yi)(yi)(yi)般來(lai)講一(yi)(yi)(yi)般電(dian)(dian)(dian)源適配器的真實滿載(zai)電(dian)(dian)(dian)壓(ya)也不(bu)一(yi)(yi)(yi)定和標稱電(dian)(dian)(dian)壓(ya)完(wan)(wan)全(quan)一(yi)(yi)(yi)致，由于電(dian)(dian)(dian)子元(yuan)器件的特點不(bu)太可能完(wan)(wan)全(quan)一(yi)(yi)(yi)致，因此有(you)一(yi)(yi)(yi)定的偏(pian)差，偏(pian)差越小，對電(dian)(dian)(dian)子元(yuan)器件的一(yi)(yi)(yi)致性規定越高(gao)，制造的成本費就(jiu)(jiu)高(gao)了(le)，因此價錢也就(jiu)(jiu)貴(gui)一(yi)(yi)(yi)些了(le)。

　　此(ci)外(wai)，有(you)關標稱的電(dian)流(liu)值(zhi)，不管(guan)一切電(dian)源(yuan)(yuan)(yuan)常有(you)一定的內電(dian)阻(zu)，因(yin)而當電(dian)源(yuan)(yuan)(yuan)輸(shu)出(chu)電(dian)流(liu)的那時(shi)候，會在(zai)內部造(zao)(zao)成壓力(li)降(jiang)，造(zao)(zao)成倆件事兒，一個是造(zao)(zao)成發熱量，因(yin)此(ci)電(dian)源(yuan)(yuan)(yuan)會熱，另一個是造(zao)(zao)成輸(shu)出(chu)電(dian)壓減(jian)少，等于內部耗費。

　　二、全是一樣標稱電壓的電源，輸出電流不一樣，能(neng)否用在(zai)同一臺本子上(shang)?

　　電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)壓一樣，輸(shu)出電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)不一樣，能否(fou)(fou)用(yong)在(zai)(zai)(zai)同一臺(tai)本(ben)子上(shang)。基礎的(de)(de)(de)標(biao)(biao)準是大(da)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)能夠替代小(xiao)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)。估(gu)算許多人會那樣想(xiang)，感覺(jue)大(da)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)會燒毀本(ben)子，由于(yu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)變大(da)嘛。事(shi)實上(shang)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)多少在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)壓同樣的(de)(de)(de)狀況(kuang)下在(zai)(zai)(zai)于(yu)負荷(he)，呵呵呵，想(xiang)一想(xiang)初級中學的(de)(de)(de)物理(li)學就(jiu)(jiu)知道。當本(ben)子長時(shi)間負荷(he)運行的(de)(de)(de)那時(shi)候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)大(da)點(dian)，本(ben)子進(jin)到關機的(de)(de)(de)那時(shi)候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)就(jiu)(jiu)小(xiao)些，大(da)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)有充足(zu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)容(rong)(rong)量。相(xiang)反，許多人用(yong)56w的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)替代72w的(de)(de)(de)用(yong)起來也沒有什么難(nan)題，緣故是一般(ban) 電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)適配(pei)器(qi)的(de)(de)(de)設計方案留出一定(ding)的(de)(de)(de)容(rong)(rong)量，負荷(he)輸(shu)出功(gong)率(lv)(lv)(lv)必須低于(yu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)出功(gong)率(lv)(lv)(lv)，因(yin)此這類替代在(zai)(zai)(zai)一般(ban)應用(yong)上(shang)是行得通的(de)(de)(de)，可是剩下的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)出功(gong)率(lv)(lv)(lv)容(rong)(rong)量就(jiu)(jiu)非常少了，一旦你(ni)的(de)(de)(de)本(ben)子接了許多外接設備，例如二塊usb固態盤(pan)，隨后cpu飛速(su)運行，還有一個基座，上(shang)邊來個光驅飛速(su)讀盤(pan)，加上(shang)另(ling)外給電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)，估(gu)算就(jiu)(jiu)風險了，要隨時(shi)隨地(di)用(yong)手摸下你(ni)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)是否(fou)(fou)早已能夠煮蛋了。因(yin)此盡量不要用(yong)小(xiao)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)替代大(da)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)。

　　三(san)、一模(mo)一樣的設(she)備，他人的電(dian)源溫溫的，我的一直很燙，為何?

　　先不必猜疑你的(de)(de)(de)電源不太好，先看一(yi)下你的(de)(de)(de)本子(zi)在干嘛(ma)，是(shi)否像上邊(bian)說(shuo)的(de)(de)(de)二(er)塊USB固態盤，CPU飛速(su)運(yun)行，固態盤瘋狂讀(du)寫能力(li)，光驅飛速(su)讀(du)盤，另(ling)外(wai)給電池充電，高聲放著歌曲(qu)，顯示(shi)器亮度(du)較大，無線網卡一(yi)直在探測數據(ju)信號這些(xie)，靈活(huo)運(yun)用(yong)電源管理方法，依據(ju)每(mei)日(ri)任務有效調(diao)節本子(zi)的(de)(de)(de)工作態度(du)是(shi)很關鍵(jian)的(de)(de)(de)。

　　四、電(dian)(dian)源標(biao)稱電(dian)(dian)壓比我的本子(zi)充電(dian)(dian)電(dian)(dian)池電(dian)(dian)壓高許多，不容易(yi)出事(shi)了吧?

　　最(zui)先，要了解(jie)的是(shi)，電(dian)(dian)源給本子供電(dian)(dian)系統與充電(dian)(dian)電(dian)(dian)池(chi)給本子供電(dian)(dian)系統是(shi)不一(yi)樣的。

　　充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)供電(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)輸出是(shi)(shi)純直流電(dian)(dian)(dian)(dian)(dian)(dian)，整潔得很(hen)，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓既不太(tai)可能也(ye)不用設計方案得很(hen)高(gao)，鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)有(you)機化(hua)學特點(dian)決(jue)策了一節鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯的(de)(de)輸出電(dian)(dian)(dian)(dian)(dian)(dian)壓只有(you)在(zai)3.6V上(shang)(shang)下，因此許(xu)多充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)全(quan)是(shi)(shi)選用三級(ji)串連(lian)的(de)(de)方法，10.8V也(ye)就變成很(hen)時興的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓。一些充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)標(biao)稱值比3.6V的(de)(de)整數(shu)倍稍(shao)大一些，例如3.7V或(huo)是(shi)(shi)11.2V這些，實際(ji)上(shang)(shang)是(shi)(shi)以(yi)便維(wei)護(hu)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。

　　電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系統，狀況就繁(fan)雜(za)一(yi)些，最先(xian)必須對添加電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)開展進一(yi)步的(de)(de)穩壓(ya)(ya)管濾波器，以確保在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)特(te)性不非常好的(de)(de)狀況下平穩工(gong)作(zuo)中(zhong)，穩壓(ya)(ya)管后的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)分(fen)為2個一(yi)部分(fen)，一(yi)路(lu)(lu)給本子工(gong)作(zuo)中(zhong)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系統，另(ling)一(yi)路(lu)(lu)給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，給本子供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系統的(de)(de)那(nei)一(yi)部分(fen)同充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系統的(de)(de)那(nei)時候同樣，而給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)那(nei)一(yi)部分(fen)必須根據充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)控制(zhi)回路(lu)(lu)才能夠加進鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯上，控制(zhi)回路(lu)(lu)能夠很繁(fan)雜(za)，因(yin)此電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)務必超過鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)才有充(chong)(chong)足的(de)(de)工(gong)作(zuo)能力供(gong)(gong)貨給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)控制(zhi)回路(lu)(lu)的(de)(de)各模(mo)塊。最終真(zhen)實加進鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯上的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)絕不會就是你的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)標稱(cheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)。放心好了(le)。
