電源適配器的幾個常見問題!

　　一、電(dian)(dian)源適配器(下稱(cheng)電(dian)(dian)源)的(de)(de)標稱(cheng)電(dian)(dian)壓(ya)和電(dian)(dian)流(liu)代表什(shen)么意思?最先，一般電(dian)(dian)源標稱(cheng)的(de)(de)電(dian)(dian)壓(ya)，就(jiu)是(shi)指引路輸(shu)(shu)出的(de)(de)電(dian)(dian)壓(ya)，也就(jiu)是(shi)說外邊不接一切負荷，沒有電(dian)(dian)流(liu)輸(shu)(shu)出那時候(hou)的(de)(de)電(dian)(dian)壓(ya)，因(yin)此還可以了解為，此電(dian)(dian)壓(ya)就(jiu)是(shi)說電(dian)(dian)源輸(shu)(shu)出電(dian)(dian)壓(ya)的(de)(de)限制。

　　針對電(dian)源內部(bu)應用了(le)積(ji)極(ji)穩壓管(guan)的(de)(de)元器件(jian)的(de)(de)狀況下(xia)，即便電(dian)壓電(dian)壓有一(yi)定的(de)(de)起伏，其輸(shu)出(chu)(chu)都(dou)是穩定值，像(xiang)目(mu)前市面上一(yi)般的(de)(de)小變(bian)電(dian)器，例(li)如(ru)mp3播放(fang)器這類配(pei)的(de)(de)電(dian)源，假(jia)如(ru)電(dian)壓起伏，該電(dian)源的(de)(de)輸(shu)出(chu)(chu)也不容易(yi)隨著起伏的(de)(de)。

　　一(yi)(yi)般來講(jiang)一(yi)(yi)般電(dian)源適(shi)配器的(de)真實滿載(zai)電(dian)壓也(ye)不一(yi)(yi)定和標稱電(dian)壓完全一(yi)(yi)致，由于電(dian)子元器件的(de)特點不太可能(neng)完全一(yi)(yi)致，因此有一(yi)(yi)定的(de)偏差(cha)(cha)，偏差(cha)(cha)越(yue)小，對(dui)電(dian)子元器件的(de)一(yi)(yi)致性規定越(yue)高，制造的(de)成(cheng)本費就(jiu)高了(le)，因此價錢也(ye)就(jiu)貴一(yi)(yi)些了(le)。

　　此外，有關標稱的(de)電流值，不管一(yi)(yi)切電源常有一(yi)(yi)定的(de)內(nei)電阻，因而(er)當電源輸出電流的(de)那時候，會在內(nei)部造(zao)成壓(ya)力降，造(zao)成倆件事兒，一(yi)(yi)個是造(zao)成發熱量，因此電源會熱，另一(yi)(yi)個是造(zao)成輸出電壓(ya)減少，等于內(nei)部耗費。

　　二(er)、全是一(yi)樣標稱電壓的電源，輸出電流(liu)不一(yi)樣，能否用在(zai)同一(yi)臺本(ben)子上?

　　電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)壓(ya)一(yi)(yi)(yi)樣(yang)，輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不一(yi)(yi)(yi)樣(yang)，能(neng)否用(yong)(yong)在(zai)(zai)同一(yi)(yi)(yi)臺本(ben)子(zi)(zi)上(shang)(shang)(shang)。基(ji)礎的(de)(de)(de)(de)(de)標(biao)(biao)準是大(da)(da)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)能(neng)夠(gou)替(ti)代(dai)小(xiao)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)。估(gu)(gu)算(suan)許(xu)(xu)多(duo)人會(hui)那樣(yang)想，感覺大(da)(da)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)會(hui)燒毀本(ben)子(zi)(zi)，由于電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)變大(da)(da)嘛。事實上(shang)(shang)(shang)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)多(duo)少在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)壓(ya)同樣(yang)的(de)(de)(de)(de)(de)狀況下在(zai)(zai)于負荷，呵呵呵，想一(yi)(yi)(yi)想初(chu)級中學的(de)(de)(de)(de)(de)物理學就(jiu)知道(dao)。當(dang)本(ben)子(zi)(zi)長時(shi)間負荷運行的(de)(de)(de)(de)(de)那時(shi)候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)(da)點，本(ben)子(zi)(zi)進到關機的(de)(de)(de)(de)(de)那時(shi)候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)就(jiu)小(xiao)些，大(da)(da)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)有充足的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)容(rong)量(liang)。相反，許(xu)(xu)多(duo)人用(yong)(yong)56w的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)替(ti)代(dai)72w的(de)(de)(de)(de)(de)用(yong)(yong)起來(lai)也沒有什么難題，緣故(gu)是一(yi)(yi)(yi)般(ban)(ban) 電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器的(de)(de)(de)(de)(de)設計方案留出(chu)一(yi)(yi)(yi)定的(de)(de)(de)(de)(de)容(rong)量(liang)，負荷輸(shu)(shu)出(chu)功率必須低(di)于電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)輸(shu)(shu)出(chu)功率，因(yin)此(ci)這類替(ti)代(dai)在(zai)(zai)一(yi)(yi)(yi)般(ban)(ban)應用(yong)(yong)上(shang)(shang)(shang)是行得通的(de)(de)(de)(de)(de)，可是剩下的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)輸(shu)(shu)出(chu)功率容(rong)量(liang)就(jiu)非常少了，一(yi)(yi)(yi)旦你(ni)的(de)(de)(de)(de)(de)本(ben)子(zi)(zi)接(jie)了許(xu)(xu)多(duo)外(wai)接(jie)設備(bei)，例如(ru)二塊usb固態盤，隨后cpu飛(fei)速運行，還有一(yi)(yi)(yi)個基(ji)座，上(shang)(shang)(shang)邊來(lai)個光驅飛(fei)速讀盤，加上(shang)(shang)(shang)另(ling)外(wai)給電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)，估(gu)(gu)算(suan)就(jiu)風險(xian)了，要(yao)隨時(shi)隨地用(yong)(yong)手摸下你(ni)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)是否早已(yi)能(neng)夠(gou)煮蛋了。因(yin)此(ci)盡量(liang)不要(yao)用(yong)(yong)小(xiao)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)替(ti)代(dai)大(da)(da)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)。

　　三(san)、一模(mo)一樣的(de)設備(bei)，他人的(de)電源溫溫的(de)，我的(de)一直很燙(tang)，為何?

　　先不必猜疑你(ni)的電(dian)源(yuan)不太好，先看一下你(ni)的本子(zi)在干嘛(ma)，是(shi)否像上邊說的二塊USB固態盤(pan)(pan)，CPU飛(fei)速(su)運(yun)行，固態盤(pan)(pan)瘋(feng)狂讀寫(xie)能(neng)力，光驅飛(fei)速(su)讀盤(pan)(pan)，另(ling)外給電(dian)池充(chong)電(dian)，高(gao)聲放著歌曲，顯示器(qi)亮度(du)(du)較大，無線網卡一直在探測(ce)數據信號這些(xie)，靈活(huo)運(yun)用電(dian)源(yuan)管理方法，依據每(mei)日任務有效調節本子(zi)的工(gong)作態度(du)(du)是(shi)很關(guan)鍵的。

　　四、電源標稱(cheng)電壓比我(wo)的本子充(chong)電電池電壓高許多，不容易出事了吧?

　　最先，要了解的是，電源(yuan)給本子供電系(xi)統(tong)與充電電池給本子供電系(xi)統(tong)是不一樣的。

　　充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)供(gong)電(dian)(dian)(dian)(dian)系(xi)統，充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)的輸出是(shi)純直流電(dian)(dian)(dian)(dian)，整潔得很(hen)(hen)，充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)(dian)壓(ya)既不太(tai)可能也(ye)不用(yong)設計方案得很(hen)(hen)高，鋰電(dian)(dian)(dian)(dian)的有機化學(xue)特點決策了一(yi)節鋰電(dian)(dian)(dian)(dian)芯的輸出電(dian)(dian)(dian)(dian)壓(ya)只有在(zai)3.6V上(shang)下(xia)，因(yin)此許多充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)全(quan)是(shi)選用(yong)三級串連的方法，10.8V也(ye)就變成很(hen)(hen)時(shi)興的充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)。一(yi)些充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)的標稱(cheng)值比3.6V的整數倍稍大一(yi)些，例如3.7V或是(shi)11.2V這(zhe)些，實際(ji)上(shang)是(shi)以便維護充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)。

　　電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)，狀況(kuang)就繁雜(za)一(yi)些，最(zui)先必(bi)須(xu)(xu)對(dui)添加(jia)(jia)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)開展進一(yi)步的(de)(de)(de)穩(wen)壓(ya)(ya)管濾波器，以確(que)保在電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)特性不非常好的(de)(de)(de)狀況(kuang)下平穩(wen)工(gong)作中(zhong)，穩(wen)壓(ya)(ya)管后的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)分(fen)為2個一(yi)部(bu)(bu)分(fen)，一(yi)路(lu)給本子(zi)工(gong)作中(zhong)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)，另一(yi)路(lu)給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，給本子(zi)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)的(de)(de)(de)那(nei)一(yi)部(bu)(bu)分(fen)同(tong)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)的(de)(de)(de)那(nei)時(shi)候同(tong)樣，而給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)那(nei)一(yi)部(bu)(bu)分(fen)必(bi)須(xu)(xu)根據充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)控制回路(lu)才能夠加(jia)(jia)進鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)上，控制回路(lu)能夠很繁雜(za)，因此(ci)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)務必(bi)超過鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)才有充(chong)足(zu)的(de)(de)(de)工(gong)作能力供(gong)(gong)貨給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)控制回路(lu)的(de)(de)(de)各(ge)模塊。最(zui)終真實加(jia)(jia)進鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)上的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)絕不會就是你的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)標稱的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)。放(fang)心好了。
