電源適配器的幾個常見問題!

　　一(yi)、電(dian)(dian)(dian)(dian)源(yuan)適配(pei)器(qi)(下稱電(dian)(dian)(dian)(dian)源(yuan))的標稱電(dian)(dian)(dian)(dian)壓(ya)(ya)和電(dian)(dian)(dian)(dian)流(liu)代表什么意思?最先，一(yi)般(ban)電(dian)(dian)(dian)(dian)源(yuan)標稱的電(dian)(dian)(dian)(dian)壓(ya)(ya)，就(jiu)是指引路(lu)輸出的電(dian)(dian)(dian)(dian)壓(ya)(ya)，也(ye)就(jiu)是說外邊不(bu)接一(yi)切負荷，沒有電(dian)(dian)(dian)(dian)流(liu)輸出那時候的電(dian)(dian)(dian)(dian)壓(ya)(ya)，因此還可以了解為，此電(dian)(dian)(dian)(dian)壓(ya)(ya)就(jiu)是說電(dian)(dian)(dian)(dian)源(yuan)輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)的限制。

　　針對電(dian)(dian)源(yuan)內部(bu)應用了積(ji)極穩壓管的(de)(de)元器(qi)(qi)件的(de)(de)狀況下，即便電(dian)(dian)壓電(dian)(dian)壓有一(yi)定(ding)的(de)(de)起(qi)伏(fu)(fu)(fu)，其輸(shu)出都(dou)是(shi)穩定(ding)值，像目前市面上(shang)一(yi)般的(de)(de)小(xiao)變電(dian)(dian)器(qi)(qi)，例如mp3播放器(qi)(qi)這類(lei)配的(de)(de)電(dian)(dian)源(yuan)，假(jia)如電(dian)(dian)壓起(qi)伏(fu)(fu)(fu)，該電(dian)(dian)源(yuan)的(de)(de)輸(shu)出也不容易隨著起(qi)伏(fu)(fu)(fu)的(de)(de)。

　　一般來講一般電(dian)(dian)源(yuan)適配器的(de)真實(shi)滿載電(dian)(dian)壓也(ye)不一定(ding)和標稱電(dian)(dian)壓完(wan)全一致(zhi)(zhi)，由于電(dian)(dian)子(zi)元器件(jian)的(de)特點不太可能完(wan)全一致(zhi)(zhi)，因此有一定(ding)的(de)偏(pian)差(cha)(cha)，偏(pian)差(cha)(cha)越小(xiao)，對電(dian)(dian)子(zi)元器件(jian)的(de)一致(zhi)(zhi)性規定(ding)越高，制造的(de)成本費就高了(le)，因此價錢也(ye)就貴一些了(le)。

　　此外，有(you)(you)關標稱(cheng)的(de)(de)電(dian)流值，不管(guan)一切電(dian)源常有(you)(you)一定的(de)(de)內電(dian)阻(zu)，因(yin)而當(dang)電(dian)源輸(shu)出電(dian)流的(de)(de)那時候(hou)，會(hui)在內部造(zao)成壓力降，造(zao)成倆件事兒，一個是造(zao)成發(fa)熱量，因(yin)此電(dian)源會(hui)熱，另一個是造(zao)成輸(shu)出電(dian)壓減(jian)少，等于內部耗費。

　　二、全(quan)是一樣(yang)標稱(cheng)電壓的電源，輸出(chu)電流不(bu)一樣(yang)，能否(fou)用(yong)在同一臺本子上?

　　電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)壓一(yi)樣(yang)，輸出電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不一(yi)樣(yang)，能(neng)否用(yong)在(zai)同(tong)一(yi)臺(tai)本(ben)(ben)子(zi)上(shang)(shang)。基礎的(de)(de)(de)標準是(shi)(shi)(shi)大(da)標稱電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)能(neng)夠(gou)(gou)替(ti)代(dai)小標稱電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)。估算許(xu)(xu)多人會(hui)那(nei)樣(yang)想(xiang)，感覺(jue)大(da)標稱電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)會(hui)燒毀本(ben)(ben)子(zi)，由于電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)變大(da)嘛。事實上(shang)(shang)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)多少(shao)在(zai)電(dian)(dian)(dian)(dian)(dian)壓同(tong)樣(yang)的(de)(de)(de)狀(zhuang)況下在(zai)于負(fu)荷(he)(he)，呵(he)呵(he)呵(he)，想(xiang)一(yi)想(xiang)初級中學(xue)的(de)(de)(de)物理學(xue)就(jiu)知道。當本(ben)(ben)子(zi)長時(shi)間負(fu)荷(he)(he)運(yun)行的(de)(de)(de)那(nei)時(shi)候(hou)，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)點(dian)，本(ben)(ben)子(zi)進到關機的(de)(de)(de)那(nei)時(shi)候(hou)，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)就(jiu)小些，大(da)標稱電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)有充(chong)足的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)容量(liang)。相反，許(xu)(xu)多人用(yong)56w的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)替(ti)代(dai)72w的(de)(de)(de)用(yong)起來(lai)也沒有什么(me)難題，緣故(gu)是(shi)(shi)(shi)一(yi)般(ban)(ban) 電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器的(de)(de)(de)設計方(fang)案留出一(yi)定的(de)(de)(de)容量(liang)，負(fu)荷(he)(he)輸出功(gong)率(lv)(lv)必須低于電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)輸出功(gong)率(lv)(lv)，因此這類替(ti)代(dai)在(zai)一(yi)般(ban)(ban)應(ying)用(yong)上(shang)(shang)是(shi)(shi)(shi)行得通的(de)(de)(de)，可(ke)是(shi)(shi)(shi)剩下的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)輸出功(gong)率(lv)(lv)容量(liang)就(jiu)非常少(shao)了(le)，一(yi)旦(dan)你的(de)(de)(de)本(ben)(ben)子(zi)接(jie)了(le)許(xu)(xu)多外接(jie)設備，例(li)如(ru)二塊usb固態盤，隨(sui)后cpu飛(fei)速運(yun)行，還有一(yi)個基座，上(shang)(shang)邊來(lai)個光驅飛(fei)速讀盤，加上(shang)(shang)另外給電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)，估算就(jiu)風險了(le)，要隨(sui)時(shi)隨(sui)地用(yong)手摸(mo)下你的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)是(shi)(shi)(shi)否早已能(neng)夠(gou)(gou)煮蛋(dan)了(le)。因此盡量(liang)不要用(yong)小電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)替(ti)代(dai)大(da)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(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，為(wei)何?

　　先不(bu)(bu)必(bi)猜疑你(ni)的(de)電(dian)源不(bu)(bu)太(tai)好，先看一(yi)下你(ni)的(de)本(ben)子在(zai)干嘛(ma)，是(shi)否像上邊說(shuo)的(de)二(er)塊USB固(gu)態(tai)盤(pan)，CPU飛(fei)速運行(xing)，固(gu)態(tai)盤(pan)瘋狂讀寫能力，光驅飛(fei)速讀盤(pan)，另外給(gei)電(dian)池充電(dian)，高聲放著(zhu)歌曲，顯示器亮度較大，無線(xian)網卡一(yi)直在(zai)探測數據信號這些，靈活(huo)運用電(dian)源管理方法，依據每(mei)日任務有效調(diao)節本(ben)子的(de)工作態(tai)度是(shi)很關鍵的(de)。

　　四、電(dian)源標稱(cheng)電(dian)壓比我的本子充電(dian)電(dian)池(chi)電(dian)壓高許多，不容易出(chu)事了吧?

　　最先，要了解的(de)是(shi)，電(dian)(dian)(dian)源(yuan)給(gei)本(ben)(ben)子供電(dian)(dian)(dian)系統與充電(dian)(dian)(dian)電(dian)(dian)(dian)池給(gei)本(ben)(ben)子供電(dian)(dian)(dian)系統是(shi)不(bu)一(yi)樣的(de)。

　　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(shu)出(chu)是純直流電(dian)(dian)(dian)(dian)(dian)(dian)，整潔(jie)得很，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(ya)(ya)既(ji)不太可能(neng)也(ye)不用設計(ji)方(fang)案得很高，鋰電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)有(you)機化學特點決策了(le)一(yi)節鋰電(dian)(dian)(dian)(dian)(dian)(dian)芯的(de)(de)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)只有(you)在3.6V上(shang)下(xia)，因(yin)此(ci)許多充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)全是選(xuan)用三級串(chuan)連的(de)(de)方(fang)法，10.8V也(ye)就變成(cheng)很時興(xing)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(ya)(ya)。一(yi)些(xie)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)標稱值比3.6V的(de)(de)整數倍(bei)稍大一(yi)些(xie)，例(li)如(ru)3.7V或是11.2V這(zhe)些(xie)，實際上(shang)是以(yi)便維(wei)護充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。

　　電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統，狀(zhuang)況就繁雜一(yi)些，最(zui)先必須對(dui)添(tian)加(jia)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)開展進(jin)一(yi)步的(de)(de)(de)(de)(de)穩(wen)壓(ya)管(guan)濾波器(qi)，以(yi)確保在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源特性不非常好的(de)(de)(de)(de)(de)狀(zhuang)況下平(ping)穩(wen)工(gong)作中，穩(wen)壓(ya)管(guan)后(hou)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)分(fen)為2個一(yi)部(bu)分(fen)，一(yi)路給(gei)(gei)本子工(gong)作中供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統，另一(yi)路給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，給(gei)(gei)本子供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統的(de)(de)(de)(de)(de)那(nei)一(yi)部(bu)分(fen)同充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統的(de)(de)(de)(de)(de)那(nei)時候同樣(yang)，而給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)那(nei)一(yi)部(bu)分(fen)必須根(gen)據充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制回路才能(neng)夠加(jia)進(jin)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上(shang)，控(kong)(kong)制回路能(neng)夠很(hen)繁雜，因此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)務必超(chao)過鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)才有充(chong)(chong)(chong)足的(de)(de)(de)(de)(de)工(gong)作能(neng)力供(gong)貨給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制回路的(de)(de)(de)(de)(de)各模塊。最(zui)終(zhong)真(zhen)實加(jia)進(jin)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上(shang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)絕不會就是你的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源標稱的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)。放心好了。
