電源適配器的幾個常見問題!

　　一(yi)、電(dian)(dian)(dian)源(yuan)適配器(下稱(cheng)電(dian)(dian)(dian)源(yuan))的(de)標稱(cheng)電(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)流代表(biao)什么(me)意思?最先，一(yi)般電(dian)(dian)(dian)源(yuan)標稱(cheng)的(de)電(dian)(dian)(dian)壓(ya)，就是指引路輸(shu)出(chu)(chu)的(de)電(dian)(dian)(dian)壓(ya)，也就是說(shuo)外邊(bian)不接一(yi)切負(fu)荷，沒有(you)電(dian)(dian)(dian)流輸(shu)出(chu)(chu)那(nei)時候的(de)電(dian)(dian)(dian)壓(ya)，因此(ci)(ci)還可以(yi)了解為，此(ci)(ci)電(dian)(dian)(dian)壓(ya)就是說(shuo)電(dian)(dian)(dian)源(yuan)輸(shu)出(chu)(chu)電(dian)(dian)(dian)壓(ya)的(de)限制。

　　針對電源內(nei)部應用(yong)了積極(ji)穩(wen)壓(ya)管的(de)元器件的(de)狀況下(xia)，即便電壓(ya)電壓(ya)有一定的(de)起伏，其輸出都是穩(wen)定值，像目前市面上一般(ban)的(de)小變電器，例如mp3播放器這類(lei)配的(de)電源，假如電壓(ya)起伏，該(gai)電源的(de)輸出也不(bu)容易隨著起伏的(de)。

　　一(yi)般來講一(yi)般電(dian)源(yuan)適配器的(de)(de)(de)真實滿(man)載電(dian)壓也(ye)不一(yi)定和標稱電(dian)壓完全一(yi)致，由于(yu)電(dian)子(zi)元器件(jian)的(de)(de)(de)特(te)點不太可能(neng)完全一(yi)致，因(yin)此有一(yi)定的(de)(de)(de)偏(pian)差(cha)，偏(pian)差(cha)越小，對電(dian)子(zi)元器件(jian)的(de)(de)(de)一(yi)致性規定越高，制造的(de)(de)(de)成本費就(jiu)高了，因(yin)此價錢也(ye)就(jiu)貴一(yi)些(xie)了。

　　此外(wai)，有關(guan)標稱的(de)電流值，不管(guan)一(yi)切(qie)電源(yuan)常有一(yi)定(ding)的(de)內(nei)電阻，因而(er)當電源(yuan)輸出電流的(de)那時候，會(hui)在內(nei)部造(zao)成(cheng)壓(ya)力降，造(zao)成(cheng)倆件事兒，一(yi)個是(shi)造(zao)成(cheng)發熱量，因此電源(yuan)會(hui)熱，另一(yi)個是(shi)造(zao)成(cheng)輸出電壓(ya)減少，等(deng)于內(nei)部耗(hao)費。

　　二(er)、全(quan)是一樣(yang)標(biao)稱電(dian)壓的電(dian)源，輸出(chu)電(dian)流不一樣(yang)，能否(fou)用(yong)在同一臺本子(zi)上?

　　電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓一(yi)樣(yang)(yang)，輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)不一(yi)樣(yang)(yang)，能否(fou)用(yong)在(zai)同(tong)一(yi)臺本子上(shang)。基礎的(de)(de)(de)(de)(de)(de)標(biao)(biao)準是(shi)大(da)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)能夠替(ti)代(dai)(dai)小(xiao)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)。估(gu)算(suan)許多(duo)(duo)人會(hui)那樣(yang)(yang)想，感覺(jue)大(da)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)會(hui)燒(shao)毀(hui)本子，由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)變大(da)嘛(ma)。事實(shi)上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)多(duo)(duo)少(shao)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓同(tong)樣(yang)(yang)的(de)(de)(de)(de)(de)(de)狀況(kuang)下在(zai)于(yu)負荷(he)，呵呵呵，想一(yi)想初級中學的(de)(de)(de)(de)(de)(de)物理學就(jiu)知道。當本子長時(shi)(shi)間負荷(he)運行(xing)的(de)(de)(de)(de)(de)(de)那時(shi)(shi)候(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)大(da)點，本子進(jin)到關(guan)機的(de)(de)(de)(de)(de)(de)那時(shi)(shi)候(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)就(jiu)小(xiao)些(xie)，大(da)標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)有(you)充(chong)足的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)容量(liang)。相反，許多(duo)(duo)人用(yong)56w的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)替(ti)代(dai)(dai)72w的(de)(de)(de)(de)(de)(de)用(yong)起(qi)來也沒有(you)什(shen)么難題，緣故是(shi)一(yi)般(ban)(ban) 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配(pei)器的(de)(de)(de)(de)(de)(de)設(she)(she)計(ji)方案留出一(yi)定的(de)(de)(de)(de)(de)(de)容量(liang)，負荷(he)輸出功率必須低于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)輸出功率，因此這(zhe)類(lei)替(ti)代(dai)(dai)在(zai)一(yi)般(ban)(ban)應用(yong)上(shang)是(shi)行(xing)得(de)通(tong)的(de)(de)(de)(de)(de)(de)，可是(shi)剩下的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)輸出功率容量(liang)就(jiu)非常少(shao)了(le)，一(yi)旦(dan)你(ni)的(de)(de)(de)(de)(de)(de)本子接了(le)許多(duo)(duo)外(wai)接設(she)(she)備，例如二塊usb固態盤，隨后cpu飛速運行(xing)，還有(you)一(yi)個基座，上(shang)邊來個光驅飛速讀(du)盤，加(jia)上(shang)另外(wai)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，估(gu)算(suan)就(jiu)風險了(le)，要隨時(shi)(shi)隨地用(yong)手摸下你(ni)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)是(shi)否(fou)早已(yi)能夠煮蛋了(le)。因此盡量(liang)不要用(yong)小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)替(ti)代(dai)(dai)大(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)。

　　三、一(yi)(yi)模(mo)一(yi)(yi)樣的設備，他人的電源溫溫的，我的一(yi)(yi)直很燙(tang)，為何?

　　先不必(bi)猜疑你的(de)(de)電源不太好，先看一(yi)(yi)下你的(de)(de)本(ben)(ben)子在(zai)干(gan)嘛，是否像上邊說的(de)(de)二塊(kuai)USB固(gu)態(tai)盤(pan)，CPU飛(fei)速(su)運行，固(gu)態(tai)盤(pan)瘋狂(kuang)讀寫能力，光驅飛(fei)速(su)讀盤(pan)，另外給電池充電，高聲放著歌(ge)曲，顯(xian)示器亮度較大(da)，無(wu)線網(wang)卡一(yi)(yi)直(zhi)在(zai)探(tan)測數據(ju)信號這些，靈活(huo)運用電源管理方法(fa)，依(yi)據(ju)每日任務有效調節本(ben)(ben)子的(de)(de)工作態(tai)度是很關(guan)鍵的(de)(de)。

　　四、電源標稱(cheng)電壓(ya)(ya)比我的本子充(chong)電電池電壓(ya)(ya)高(gao)許(xu)多，不容易(yi)出事了吧(ba)?

　　最先，要了(le)解的(de)是，電(dian)源給(gei)本子(zi)供(gong)(gong)電(dian)系(xi)統與充電(dian)電(dian)池給(gei)本子(zi)供(gong)(gong)電(dian)系(xi)統是不一(yi)樣(yang)的(de)。

　　充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池供電(dian)(dian)(dian)(dian)(dian)系統，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池的(de)輸(shu)出是(shi)純直流電(dian)(dian)(dian)(dian)(dian)，整潔得很，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)既不(bu)太可能也(ye)不(bu)用設計方(fang)(fang)案得很高(gao)，鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)的(de)有機(ji)化學特點(dian)決策了一節鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)芯的(de)輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)只(zhi)有在3.6V上下(xia)，因此許多充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池全是(shi)選用三級串連的(de)方(fang)(fang)法，10.8V也(ye)就(jiu)變成很時興的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)。一些(xie)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池的(de)標稱值比3.6V的(de)整數(shu)倍稍大一些(xie)，例如3.7V或是(shi)11.2V這(zhe)些(xie)，實(shi)際上是(shi)以(yi)便維(wei)護充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池。

　　電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)，狀況就繁雜一些，最先必(bi)須(xu)對添加電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)開展進一步的(de)(de)穩(wen)壓(ya)(ya)管(guan)濾波器，以確保(bao)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)特性(xing)不(bu)非常好(hao)的(de)(de)狀況下平穩(wen)工作中，穩(wen)壓(ya)(ya)管(guan)后的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)分(fen)為2個(ge)一部分(fen)，一路(lu)給(gei)本(ben)(ben)子(zi)(zi)工作中供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)，另(ling)一路(lu)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，給(gei)本(ben)(ben)子(zi)(zi)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)的(de)(de)那一部分(fen)同充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)的(de)(de)那時候同樣，而(er)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)那一部分(fen)必(bi)須(xu)根據充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)控(kong)制回路(lu)才(cai)能夠加進鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上，控(kong)制回路(lu)能夠很(hen)繁雜，因此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)務(wu)必(bi)超過鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)才(cai)有充(chong)(chong)(chong)(chong)足的(de)(de)工作能力供(gong)(gong)貨給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)控(kong)制回路(lu)的(de)(de)各模塊。最終真實加進鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)絕不(bu)會就是你的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)標稱(cheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)。放心好(hao)了。
