電源適配器的幾個常見問題!

　　一(yi)、電(dian)(dian)(dian)源(yuan)適配(pei)器(下稱電(dian)(dian)(dian)源(yuan))的標稱電(dian)(dian)(dian)壓(ya)和(he)電(dian)(dian)(dian)流代表什(shen)么意思?最先，一(yi)般電(dian)(dian)(dian)源(yuan)標稱的電(dian)(dian)(dian)壓(ya)，就是指引路輸出的電(dian)(dian)(dian)壓(ya)，也就是說(shuo)外(wai)邊不接一(yi)切負(fu)荷，沒有(you)電(dian)(dian)(dian)流輸出那時(shi)候的電(dian)(dian)(dian)壓(ya)，因此還(huan)可以了解為，此電(dian)(dian)(dian)壓(ya)就是說(shuo)電(dian)(dian)(dian)源(yuan)輸出電(dian)(dian)(dian)壓(ya)的限制(zhi)。

　　針對(dui)電(dian)源(yuan)內部(bu)應(ying)用了積極穩壓管的(de)元器(qi)(qi)件的(de)狀況(kuang)下(xia)，即便電(dian)壓電(dian)壓有(you)一(yi)定的(de)起(qi)伏(fu)，其輸(shu)出(chu)都(dou)是(shi)穩定值，像(xiang)目前市面上一(yi)般(ban)的(de)小變(bian)電(dian)器(qi)(qi)，例(li)如mp3播放器(qi)(qi)這類配的(de)電(dian)源(yuan)，假如電(dian)壓起(qi)伏(fu)，該電(dian)源(yuan)的(de)輸(shu)出(chu)也不容(rong)易隨著起(qi)伏(fu)的(de)。

　　一(yi)般(ban)來講一(yi)般(ban)電源適配(pei)器(qi)的真(zhen)實(shi)滿載(zai)電壓也不(bu)一(yi)定和標(biao)稱電壓完全一(yi)致，由于電子元器(qi)件(jian)(jian)的特點(dian)不(bu)太可能完全一(yi)致，因(yin)(yin)此有一(yi)定的偏差，偏差越小(xiao)，對電子元器(qi)件(jian)(jian)的一(yi)致性(xing)規(gui)定越高(gao)，制造的成本費就高(gao)了，因(yin)(yin)此價錢也就貴一(yi)些了。

　　此外，有關標稱的電(dian)流值，不(bu)管一(yi)切電(dian)源(yuan)常有一(yi)定的內(nei)電(dian)阻(zu)，因而當電(dian)源(yuan)輸出電(dian)流的那時候(hou)，會在內(nei)部(bu)造(zao)成(cheng)壓力(li)降，造(zao)成(cheng)倆件事(shi)兒，一(yi)個是(shi)造(zao)成(cheng)發熱量，因此電(dian)源(yuan)會熱，另一(yi)個是(shi)造(zao)成(cheng)輸出電(dian)壓減少，等于內(nei)部(bu)耗費。

　　二(er)、全是一(yi)樣標稱電(dian)壓的電(dian)源，輸出電(dian)流不一(yi)樣，能否用(yong)在同一(yi)臺本子上?

　　電(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)壓一(yi)(yi)樣，輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)不(bu)一(yi)(yi)樣，能否(fou)用在同一(yi)(yi)臺(tai)本子上(shang)(shang)。基(ji)礎的(de)(de)(de)標(biao)準是大(da)(da)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源能夠(gou)替(ti)代(dai)小(xiao)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源。估算許(xu)(xu)多(duo)人會(hui)那(nei)樣想，感覺大(da)(da)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源會(hui)燒毀本子，由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)變大(da)(da)嘛。事實上(shang)(shang)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)多(duo)少在電(dian)(dian)(dian)(dian)(dian)(dian)壓同樣的(de)(de)(de)狀況下(xia)在于(yu)負(fu)荷(he)，呵(he)(he)(he)呵(he)(he)(he)呵(he)(he)(he)，想一(yi)(yi)想初級中學的(de)(de)(de)物理學就(jiu)知(zhi)道。當本子長時間負(fu)荷(he)運(yun)行的(de)(de)(de)那(nei)時候(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大(da)(da)點，本子進(jin)到關機的(de)(de)(de)那(nei)時候(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)就(jiu)小(xiao)些，大(da)(da)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源有(you)充足的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)容(rong)(rong)量。相(xiang)反，許(xu)(xu)多(duo)人用56w的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源替(ti)代(dai)72w的(de)(de)(de)用起來也沒有(you)什么難題，緣故是一(yi)(yi)般 電(dian)(dian)(dian)(dian)(dian)(dian)源適(shi)配(pei)器(qi)的(de)(de)(de)設計方(fang)案留出(chu)一(yi)(yi)定的(de)(de)(de)容(rong)(rong)量，負(fu)荷(he)輸出(chu)功率必須低于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)源輸出(chu)功率，因此(ci)這類替(ti)代(dai)在一(yi)(yi)般應用上(shang)(shang)是行得通(tong)的(de)(de)(de)，可是剩下(xia)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源輸出(chu)功率容(rong)(rong)量就(jiu)非常(chang)少了(le)，一(yi)(yi)旦你的(de)(de)(de)本子接了(le)許(xu)(xu)多(duo)外接設備，例(li)如二塊usb固態盤，隨后cpu飛速運(yun)行，還(huan)有(you)一(yi)(yi)個基(ji)座(zuo)，上(shang)(shang)邊(bian)來個光驅(qu)飛速讀盤，加上(shang)(shang)另外給電(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)，估算就(jiu)風險了(le)，要(yao)隨時隨地(di)用手摸下(xia)你的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源是否(fou)早已(yi)能夠(gou)煮蛋了(le)。因此(ci)盡量不(bu)要(yao)用小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)源替(ti)代(dai)大(da)(da)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)源。

　　三、一模一樣的設備，他人的電源溫溫的，我的一直(zhi)很燙，為何?

　　先不必猜(cai)疑(yi)你的(de)電源不太好(hao)，先看(kan)一(yi)下你的(de)本(ben)子(zi)在干嘛，是(shi)否(fou)像上(shang)邊說(shuo)的(de)二塊USB固態盤(pan)，CPU飛速(su)運(yun)行，固態盤(pan)瘋(feng)狂讀(du)寫能力，光驅飛速(su)讀(du)盤(pan)，另外(wai)給(gei)電池(chi)充電，高(gao)聲放著(zhu)歌曲，顯示器(qi)亮(liang)度較大，無線網卡一(yi)直在探測數(shu)據(ju)信號(hao)這些，靈活運(yun)用電源管理方法，依據(ju)每(mei)日(ri)任務有效(xiao)調節本(ben)子(zi)的(de)工作態度是(shi)很關鍵的(de)。

　　四、電(dian)(dian)(dian)源標稱(cheng)電(dian)(dian)(dian)壓比(bi)我的(de)本子充電(dian)(dian)(dian)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓高許多，不容(rong)易出事了吧(ba)?

　　最先，要(yao)了解的是，電(dian)源(yuan)給本(ben)子供電(dian)系(xi)統與充電(dian)電(dian)池給本(ben)子供電(dian)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，充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)輸出是純直流電(dian)(dian)(dian)(dian)，整潔得(de)(de)很(hen)，充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)既不太可能(neng)也(ye)(ye)不用設計(ji)方案(an)得(de)(de)很(hen)高，鋰(li)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)有機化學特點(dian)決策了一(yi)節鋰(li)電(dian)(dian)(dian)(dian)芯的(de)(de)(de)(de)輸出電(dian)(dian)(dian)(dian)壓(ya)只有在(zai)3.6V上下(xia)，因此許多充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)全是選用三(san)級串連的(de)(de)(de)(de)方法，10.8V也(ye)(ye)就(jiu)變成(cheng)很(hen)時(shi)興的(de)(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(xie)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)標稱值比3.6V的(de)(de)(de)(de)整數倍稍大一(yi)些(xie)，例如3.7V或是11.2V這些(xie)，實(shi)際上是以便(bian)維護充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)。

　　電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統，狀況就繁雜一(yi)些，最(zui)先必須(xu)對添加(jia)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)開(kai)展進(jin)一(yi)步(bu)的(de)穩壓(ya)管濾波器，以確(que)保(bao)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源特性(xing)不非常(chang)好的(de)狀況下平(ping)穩工作(zuo)中，穩壓(ya)管后的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)分(fen)(fen)為(wei)2個一(yi)部分(fen)(fen)，一(yi)路(lu)給(gei)(gei)(gei)本子工作(zuo)中供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統，另一(yi)路(lu)給(gei)(gei)(gei)電(dian)(dian)(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)(dian)(dian)，給(gei)(gei)(gei)本子供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統的(de)那一(yi)部分(fen)(fen)同充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(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)(dian)(dian)系(xi)統的(de)那時候同樣，而給(gei)(gei)(gei)電(dian)(dian)(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)(dian)(dian)的(de)那一(yi)部分(fen)(fen)必須(xu)根據充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(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)(dian)(dian)控制(zhi)回(hui)路(lu)才能(neng)夠加(jia)進(jin)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上，控制(zhi)回(hui)路(lu)能(neng)夠很繁雜，因此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)務必超過鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)才有充(chong)(chong)(chong)足的(de)工作(zuo)能(neng)力供(gong)貨(huo)給(gei)(gei)(gei)電(dian)(dian)(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)(dian)(dian)控制(zhi)回(hui)路(lu)的(de)各模塊。最(zui)終真實(shi)加(jia)進(jin)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)絕(jue)不會就是你的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源標稱的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)。放(fang)心好了。
