電源適配器的幾個常見問題!

　　一(yi)、電(dian)源(yuan)(yuan)適配器(qi)(下稱電(dian)源(yuan)(yuan))的(de)標稱電(dian)壓和電(dian)流代(dai)表什(shen)么意思?最先，一(yi)般電(dian)源(yuan)(yuan)標稱的(de)電(dian)壓，就(jiu)是指引(yin)路輸出的(de)電(dian)壓，也就(jiu)是說外邊不(bu)接一(yi)切(qie)負(fu)荷，沒有電(dian)流輸出那時候的(de)電(dian)壓，因此(ci)還(huan)可以了(le)解為(wei)，此(ci)電(dian)壓就(jiu)是說電(dian)源(yuan)(yuan)輸出電(dian)壓的(de)限制。

　　針對(dui)電(dian)源內(nei)部應用(yong)了積極(ji)穩壓管的(de)元(yuan)器件的(de)狀(zhuang)況下，即便電(dian)壓電(dian)壓有(you)一(yi)定的(de)起(qi)伏，其(qi)輸出都是穩定值，像目前市面上一(yi)般的(de)小(xiao)變電(dian)器，例(li)如mp3播放器這類配(pei)的(de)電(dian)源，假(jia)如電(dian)壓起(qi)伏，該電(dian)源的(de)輸出也(ye)不(bu)容易隨著起(qi)伏的(de)。

　　一般來(lai)講一般電(dian)源適配器的真實(shi)滿載電(dian)壓(ya)也(ye)不一定和標稱電(dian)壓(ya)完全(quan)一致(zhi)(zhi)，由(you)于電(dian)子元(yuan)(yuan)器件(jian)的特點不太可能完全(quan)一致(zhi)(zhi)，因此(ci)(ci)有一定的偏差(cha)，偏差(cha)越小(xiao)，對(dui)電(dian)子元(yuan)(yuan)器件(jian)的一致(zhi)(zhi)性規(gui)定越高(gao)，制造的成本費就高(gao)了(le)，因此(ci)(ci)價錢也(ye)就貴(gui)一些了(le)。

　　此外，有(you)關標稱的電(dian)(dian)流(liu)值(zhi)，不管(guan)一切(qie)電(dian)(dian)源(yuan)常有(you)一定(ding)的內(nei)電(dian)(dian)阻，因而(er)當(dang)電(dian)(dian)源(yuan)輸出(chu)電(dian)(dian)流(liu)的那時(shi)候，會在內(nei)部造(zao)成壓(ya)力降，造(zao)成倆件(jian)事兒，一個是造(zao)成發熱(re)量，因此電(dian)(dian)源(yuan)會熱(re)，另一個是造(zao)成輸出(chu)電(dian)(dian)壓(ya)減(jian)少，等于(yu)內(nei)部耗費。

　　二(er)、全是一樣標稱電(dian)壓(ya)的電(dian)源，輸出電(dian)流不一樣，能否用(yong)在(zai)同一臺(tai)本子上?

　　電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)壓一樣，輸(shu)出(chu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)不一樣，能否用(yong)在(zai)同一臺本(ben)子上(shang)(shang)。基礎的(de)(de)(de)(de)標(biao)準是大(da)標(biao)稱電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)能夠替(ti)代(dai)小標(biao)稱電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)。估算(suan)許(xu)多(duo)(duo)人(ren)會那樣想(xiang)，感覺大(da)標(biao)稱電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)會燒(shao)毀本(ben)子，由(you)于(yu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)變大(da)嘛。事實上(shang)(shang)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)多(duo)(duo)少在(zai)電(dian)(dian)(dian)(dian)壓同樣的(de)(de)(de)(de)狀況(kuang)下(xia)(xia)在(zai)于(yu)負荷，呵呵呵，想(xiang)一想(xiang)初級(ji)中學的(de)(de)(de)(de)物(wu)理(li)學就(jiu)知道。當(dang)本(ben)子長時(shi)間負荷運(yun)行(xing)的(de)(de)(de)(de)那時(shi)候，電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)大(da)點，本(ben)子進(jin)到(dao)關機的(de)(de)(de)(de)那時(shi)候，電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)就(jiu)小些，大(da)標(biao)稱電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)有充(chong)足的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)容(rong)量(liang)。相(xiang)反，許(xu)多(duo)(duo)人(ren)用(yong)56w的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)替(ti)代(dai)72w的(de)(de)(de)(de)用(yong)起來也沒有什么(me)難題，緣故是一般 電(dian)(dian)(dian)(dian)源(yuan)適配器的(de)(de)(de)(de)設(she)計(ji)方案留出(chu)一定的(de)(de)(de)(de)容(rong)量(liang)，負荷輸(shu)出(chu)功率(lv)(lv)必(bi)須低于(yu)電(dian)(dian)(dian)(dian)源(yuan)輸(shu)出(chu)功率(lv)(lv)，因此這類替(ti)代(dai)在(zai)一般應用(yong)上(shang)(shang)是行(xing)得通的(de)(de)(de)(de)，可是剩下(xia)(xia)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)輸(shu)出(chu)功率(lv)(lv)容(rong)量(liang)就(jiu)非常少了，一旦你(ni)的(de)(de)(de)(de)本(ben)子接(jie)了許(xu)多(duo)(duo)外接(jie)設(she)備，例如二塊usb固態盤，隨后cpu飛速運(yun)行(xing)，還有一個基座(zuo)，上(shang)(shang)邊來個光驅飛速讀盤，加上(shang)(shang)另外給電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)，估算(suan)就(jiu)風(feng)險了，要隨時(shi)隨地(di)用(yong)手(shou)摸下(xia)(xia)你(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)是否早(zao)已能夠煮蛋了。因此盡量(liang)不要用(yong)小電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)替(ti)代(dai)大(da)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)。

　　三、一模一樣的(de)設備，他人的(de)電源(yuan)溫溫的(de)，我的(de)一直很燙(tang)，為何?

　　先不必猜(cai)疑你(ni)的(de)電源(yuan)不太好，先看一下(xia)你(ni)的(de)本子在(zai)干嘛，是否像上邊說的(de)二塊USB固態盤，CPU飛速(su)(su)運行，固態盤瘋狂讀寫能力(li)，光(guang)驅飛速(su)(su)讀盤，另外(wai)給電池充電，高聲放(fang)著歌曲，顯(xian)示(shi)器亮(liang)度(du)較大，無線網(wang)卡一直(zhi)在(zai)探測數(shu)據信號這(zhe)些，靈活(huo)運用電源(yuan)管理方法(fa)，依據每日任務有(you)效調節本子的(de)工作態度(du)是很關鍵(jian)的(de)。

　　四、電(dian)(dian)(dian)源標稱電(dian)(dian)(dian)壓(ya)比我的本子充電(dian)(dian)(dian)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)高許多，不容易出(chu)事了吧(ba)?

　　最(zui)先，要了解的(de)(de)是，電(dian)(dian)源給本子(zi)供電(dian)(dian)系統與(yu)充(chong)電(dian)(dian)電(dian)(dian)池給本子(zi)供電(dian)(dian)系統是不一樣的(de)(de)。

　　充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)供電(dian)(dian)系統，充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)的(de)(de)輸出(chu)是純直流(liu)電(dian)(dian)，整潔得很，充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)的(de)(de)電(dian)(dian)壓既不(bu)太可能也不(bu)用設計方案得很高，鋰電(dian)(dian)的(de)(de)有(you)機(ji)化學特點決策了(le)一(yi)節(jie)鋰電(dian)(dian)芯的(de)(de)輸出(chu)電(dian)(dian)壓只(zhi)有(you)在3.6V上(shang)下，因此許多充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)全是選用三級(ji)串連的(de)(de)方法，10.8V也就變(bian)成很時興(xing)的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)壓。一(yi)些充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)的(de)(de)標稱值比3.6V的(de)(de)整數倍稍(shao)大一(yi)些，例如3.7V或是11.2V這些，實際上(shang)是以(yi)便維(wei)護充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)。

　　電(dian)(dian)(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)(dian)(dian)系統(tong)，狀況(kuang)就繁(fan)雜一(yi)些，最先必(bi)須(xu)對添(tian)加電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)開展(zhan)進(jin)(jin)一(yi)步(bu)的穩壓(ya)(ya)管濾波器，以(yi)確保(bao)在電(dian)(dian)(dian)(dian)(dian)源(yuan)特(te)性(xing)不非常好(hao)的狀況(kuang)下平穩工作中，穩壓(ya)(ya)管后的電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)分為2個一(yi)部分，一(yi)路(lu)(lu)給(gei)本子(zi)工作中供電(dian)(dian)(dian)(dian)(dian)系統(tong)，另一(yi)路(lu)(lu)給(gei)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)，給(gei)本子(zi)供電(dian)(dian)(dian)(dian)(dian)系統(tong)的那(nei)(nei)一(yi)部分同充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池供電(dian)(dian)(dian)(dian)(dian)系統(tong)的那(nei)(nei)時(shi)候同樣，而給(gei)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)的那(nei)(nei)一(yi)部分必(bi)須(xu)根據充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)控制(zhi)回(hui)路(lu)(lu)才(cai)能夠(gou)加進(jin)(jin)鋰(li)電(dian)(dian)(dian)(dian)(dian)芯(xin)上，控制(zhi)回(hui)路(lu)(lu)能夠(gou)很繁(fan)雜，因此(ci)電(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)務必(bi)超過鋰(li)電(dian)(dian)(dian)(dian)(dian)芯(xin)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)才(cai)有充(chong)足的工作能力供貨給(gei)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)控制(zhi)回(hui)路(lu)(lu)的各模塊。最終真(zhen)實加進(jin)(jin)鋰(li)電(dian)(dian)(dian)(dian)(dian)芯(xin)上的電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)絕不會就是你的電(dian)(dian)(dian)(dian)(dian)源(yuan)標稱的電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)。放心好(hao)了。
