電源適配器的幾個常見問題!

　　一、電(dian)(dian)源(yuan)適(shi)配(pei)器(下稱(cheng)(cheng)電(dian)(dian)源(yuan))的(de)標稱(cheng)(cheng)電(dian)(dian)壓(ya)和電(dian)(dian)流(liu)代(dai)表(biao)什么意思(si)?最先，一般(ban)電(dian)(dian)源(yuan)標稱(cheng)(cheng)的(de)電(dian)(dian)壓(ya)，就(jiu)是指(zhi)引路輸出(chu)的(de)電(dian)(dian)壓(ya)，也(ye)就(jiu)是說外(wai)邊不接一切負(fu)荷，沒有電(dian)(dian)流(liu)輸出(chu)那(nei)時(shi)候的(de)電(dian)(dian)壓(ya)，因此還可以了解為，此電(dian)(dian)壓(ya)就(jiu)是說電(dian)(dian)源(yuan)輸出(chu)電(dian)(dian)壓(ya)的(de)限制。

　　針對電(dian)源(yuan)內部應用了積極穩壓管的(de)元器件的(de)狀況下(xia)，即便電(dian)壓電(dian)壓有(you)一定(ding)的(de)起伏(fu)，其輸出都是穩定(ding)值，像目前市(shi)面上(shang)一般的(de)小變電(dian)器，例如(ru)mp3播放器這類配的(de)電(dian)源(yuan)，假如(ru)電(dian)壓起伏(fu)，該(gai)電(dian)源(yuan)的(de)輸出也不容(rong)易隨著起伏(fu)的(de)。

　　一般來講一般電源適配(pei)器(qi)的(de)真實滿載電壓也不一定(ding)和標稱電壓完全(quan)一致，由于電子元器(qi)件的(de)特點不太可能完全(quan)一致，因此有一定(ding)的(de)偏差，偏差越小，對電子元器(qi)件的(de)一致性(xing)規定(ding)越高(gao)，制造的(de)成本費就高(gao)了，因此價錢也就貴一些了。

　　此(ci)外，有(you)(you)關(guan)標稱的電流值(zhi)，不管一(yi)(yi)切電源(yuan)(yuan)常有(you)(you)一(yi)(yi)定(ding)的內(nei)電阻，因而當電源(yuan)(yuan)輸出(chu)電流的那時候，會(hui)在內(nei)部造成(cheng)(cheng)壓(ya)力降，造成(cheng)(cheng)倆件事兒，一(yi)(yi)個是(shi)造成(cheng)(cheng)發熱量，因此(ci)電源(yuan)(yuan)會(hui)熱，另(ling)一(yi)(yi)個是(shi)造成(cheng)(cheng)輸出(chu)電壓(ya)減少，等于內(nei)部耗費。

　　二、全是一樣(yang)標稱電(dian)壓(ya)的電(dian)源，輸(shu)出電(dian)流不一樣(yang)，能否用在同一臺本子(zi)上?

　　電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)一(yi)樣，輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不(bu)一(yi)樣，能否(fou)用(yong)(yong)(yong)在同(tong)一(yi)臺本(ben)子上(shang)(shang)。基礎的(de)(de)標(biao)(biao)準是(shi)大(da)標(biao)(biao)稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)能夠替(ti)代小標(biao)(biao)稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)。估算許(xu)多人會那(nei)樣想，感覺(jue)大(da)標(biao)(biao)稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)會燒毀本(ben)子，由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)變(bian)大(da)嘛(ma)。事實上(shang)(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)多少在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)同(tong)樣的(de)(de)狀況(kuang)下在于負荷，呵呵呵，想一(yi)想初級中學的(de)(de)物理學就(jiu)知道。當(dang)本(ben)子長時間負荷運(yun)行的(de)(de)那(nei)時候，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)點，本(ben)子進(jin)到關機的(de)(de)那(nei)時候，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)就(jiu)小些，大(da)標(biao)(biao)稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)有充足的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)容(rong)量。相(xiang)反，許(xu)多人用(yong)(yong)(yong)56w的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)替(ti)代72w的(de)(de)用(yong)(yong)(yong)起來也沒有什么難(nan)題，緣故是(shi)一(yi)般 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適配器(qi)的(de)(de)設(she)計方案留出(chu)一(yi)定的(de)(de)容(rong)量，負荷輸(shu)出(chu)功(gong)率(lv)必須低于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)輸(shu)出(chu)功(gong)率(lv)，因(yin)此(ci)這類替(ti)代在一(yi)般應(ying)用(yong)(yong)(yong)上(shang)(shang)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(yuan)(yuan)(yuan)(yuan)輸(shu)出(chu)功(gong)率(lv)容(rong)量就(jiu)非常少了(le)，一(yi)旦你(ni)的(de)(de)本(ben)子接了(le)許(xu)多外接設(she)備，例如二塊(kuai)usb固態(tai)盤(pan)，隨(sui)后cpu飛速運(yun)行，還有一(yi)個基座(zuo)，上(shang)(shang)邊來個光驅飛速讀盤(pan)，加上(shang)(shang)另(ling)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(le)，要隨(sui)時隨(sui)地用(yong)(yong)(yong)手(shou)摸下你(ni)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)是(shi)否(fou)早已能夠煮蛋了(le)。因(yin)此(ci)盡量不(bu)要用(yong)(yong)(yong)小電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)替(ti)代大(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)。

　　三、一(yi)模一(yi)樣的設備，他人的電源溫(wen)溫(wen)的，我的一(yi)直很燙，為(wei)何(he)?

　　先(xian)不(bu)必猜疑你(ni)的電(dian)源不(bu)太好，先(xian)看一下你(ni)的本子(zi)(zi)在干嘛，是否(fou)像上邊說的二塊(kuai)USB固態(tai)盤，CPU飛(fei)速(su)運(yun)行，固態(tai)盤瘋狂讀寫能力，光驅飛(fei)速(su)讀盤，另外給電(dian)池充電(dian)，高聲放著歌曲，顯示器(qi)亮(liang)度較大，無(wu)線網(wang)卡一直在探測數據(ju)信號這些(xie)，靈(ling)活運(yun)用電(dian)源管理方(fang)法(fa)，依據(ju)每日任務有效(xiao)調(diao)節本子(zi)(zi)的工作態(tai)度是很關(guan)鍵的。

　　四、電源標稱電壓比我的本(ben)子充電電池電壓高許多，不(bu)容易(yi)出事了(le)吧(ba)?

　　最(zui)先，要了解的是，電源給本子供電系(xi)統與(yu)充電電池給本子供電系(xi)統是不一樣的。

　　充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)供(gong)電(dian)(dian)(dian)(dian)系統(tong)，充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)輸(shu)出是(shi)(shi)純直流電(dian)(dian)(dian)(dian)，整(zheng)潔得很(hen)，充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)既(ji)不太可能也不用(yong)(yong)設計方案得很(hen)高，鋰電(dian)(dian)(dian)(dian)的(de)(de)(de)有機化學特點決(jue)策了一(yi)節鋰電(dian)(dian)(dian)(dian)芯(xin)的(de)(de)(de)輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)只有在3.6V上下，因(yin)此許多充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)全(quan)是(shi)(shi)選用(yong)(yong)三級串連(lian)的(de)(de)(de)方法，10.8V也就變成很(hen)時興的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)。一(yi)些充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)標稱值比3.6V的(de)(de)(de)整(zheng)數(shu)倍(bei)稍大一(yi)些，例如3.7V或是(shi)(shi)11.2V這些，實際上是(shi)(shi)以便維護充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)。

　　電(dian)(dian)(dian)(dian)(dian)源供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系(xi)統，狀況(kuang)就繁雜(za)一(yi)(yi)些，最先必(bi)須(xu)對添加電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)開展進(jin)(jin)一(yi)(yi)步的(de)(de)穩壓(ya)(ya)管濾(lv)波(bo)器，以(yi)確保(bao)在電(dian)(dian)(dian)(dian)(dian)源特(te)性不非常好(hao)的(de)(de)狀況(kuang)下(xia)平(ping)穩工(gong)作中(zhong)，穩壓(ya)(ya)管后的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)分(fen)(fen)為2個一(yi)(yi)部分(fen)(fen)，一(yi)(yi)路(lu)給本(ben)子工(gong)作中(zhong)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系(xi)統，另(ling)一(yi)(yi)路(lu)給電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)，給本(ben)子供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系(xi)統的(de)(de)那一(yi)(yi)部分(fen)(fen)同充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系(xi)統的(de)(de)那時候(hou)同樣(yang)，而給電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)那一(yi)(yi)部分(fen)(fen)必(bi)須(xu)根據充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)(zhi)回(hui)路(lu)才能(neng)夠(gou)加進(jin)(jin)鋰(li)電(dian)(dian)(dian)(dian)(dian)芯上(shang)，控(kong)制(zhi)(zhi)回(hui)路(lu)能(neng)夠(gou)很繁雜(za)，因此電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)務必(bi)超過鋰(li)電(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)才有(you)充(chong)足的(de)(de)工(gong)作能(neng)力(li)供(gong)(gong)貨給電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)(zhi)回(hui)路(lu)的(de)(de)各模(mo)塊。最終真(zhen)實加進(jin)(jin)鋰(li)電(dian)(dian)(dian)(dian)(dian)芯上(shang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)絕不會就是你(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)(ya)。放心好(hao)了。
