電源適配器的幾個常見問題!

　　一(yi)、電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(下(xia)稱(cheng)(cheng)電(dian)(dian)(dian)(dian)源(yuan))的(de)(de)標稱(cheng)(cheng)電(dian)(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)(dian)流代表什(shen)么意思?最先，一(yi)般電(dian)(dian)(dian)(dian)源(yuan)標稱(cheng)(cheng)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)，就(jiu)(jiu)是(shi)(shi)指(zhi)引(yin)路輸出的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)，也就(jiu)(jiu)是(shi)(shi)說外邊(bian)不接(jie)一(yi)切負荷，沒有電(dian)(dian)(dian)(dian)流輸出那時(shi)候的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)，因此(ci)還可以(yi)了解(jie)為(wei)，此(ci)電(dian)(dian)(dian)(dian)壓(ya)就(jiu)(jiu)是(shi)(shi)說電(dian)(dian)(dian)(dian)源(yuan)輸出電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)限制(zhi)。

　　針對(dui)電(dian)(dian)源內部(bu)應用了積極(ji)穩(wen)壓管(guan)的(de)元器(qi)件的(de)狀(zhuang)況下，即(ji)便電(dian)(dian)壓電(dian)(dian)壓有(you)一定的(de)起伏(fu)(fu)，其輸(shu)出都是穩(wen)定值(zhi)，像目前市(shi)面上一般的(de)小變(bian)電(dian)(dian)器(qi)，例如mp3播放器(qi)這類(lei)配的(de)電(dian)(dian)源，假如電(dian)(dian)壓起伏(fu)(fu)，該電(dian)(dian)源的(de)輸(shu)出也不(bu)容易隨(sui)著(zhu)起伏(fu)(fu)的(de)。

　　一(yi)(yi)(yi)般來(lai)講一(yi)(yi)(yi)般電(dian)(dian)源適(shi)配器的(de)(de)真(zhen)實滿載(zai)電(dian)(dian)壓也(ye)不一(yi)(yi)(yi)定(ding)和標稱(cheng)電(dian)(dian)壓完全一(yi)(yi)(yi)致，由于(yu)電(dian)(dian)子(zi)元器件(jian)的(de)(de)特點不太可(ke)能完全一(yi)(yi)(yi)致，因此有一(yi)(yi)(yi)定(ding)的(de)(de)偏差，偏差越小，對電(dian)(dian)子(zi)元器件(jian)的(de)(de)一(yi)(yi)(yi)致性規定(ding)越高，制造(zao)的(de)(de)成本費(fei)就(jiu)高了，因此價錢也(ye)就(jiu)貴一(yi)(yi)(yi)些(xie)了。

　　此外，有關標稱的電(dian)流(liu)值，不管一切(qie)電(dian)源(yuan)常有一定的內電(dian)阻，因而當電(dian)源(yuan)輸(shu)出(chu)電(dian)流(liu)的那時候，會在內部造(zao)(zao)成(cheng)壓力降，造(zao)(zao)成(cheng)倆(lia)件事(shi)兒，一個(ge)是造(zao)(zao)成(cheng)發(fa)熱量(liang)，因此電(dian)源(yuan)會熱，另一個(ge)是造(zao)(zao)成(cheng)輸(shu)出(chu)電(dian)壓減少，等(deng)于內部耗(hao)費(fei)。

　　二(er)、全是(shi)一樣標稱(cheng)電(dian)壓(ya)的電(dian)源，輸出電(dian)流不一樣，能否(fou)用在同一臺本(ben)子上?

　　電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)壓(ya)一(yi)(yi)樣(yang)(yang)，輸(shu)出電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不一(yi)(yi)樣(yang)(yang)，能否用(yong)在(zai)(zai)同(tong)一(yi)(yi)臺本(ben)(ben)(ben)子(zi)上。基(ji)礎的(de)(de)(de)(de)標(biao)準是大(da)(da)標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)能夠替(ti)(ti)代(dai)小標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)。估算(suan)許(xu)多(duo)人會那(nei)樣(yang)(yang)想(xiang)(xiang)，感覺大(da)(da)標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)會燒毀本(ben)(ben)(ben)子(zi)，由于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)變大(da)(da)嘛。事(shi)實上電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)多(duo)少在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)壓(ya)同(tong)樣(yang)(yang)的(de)(de)(de)(de)狀(zhuang)況下在(zai)(zai)于(yu)(yu)負荷(he)，呵(he)呵(he)呵(he)，想(xiang)(xiang)一(yi)(yi)想(xiang)(xiang)初級中學(xue)(xue)的(de)(de)(de)(de)物理學(xue)(xue)就(jiu)(jiu)知道。當(dang)本(ben)(ben)(ben)子(zi)長時(shi)間負荷(he)運(yun)行(xing)的(de)(de)(de)(de)那(nei)時(shi)候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)(da)點，本(ben)(ben)(ben)子(zi)進到(dao)關機(ji)的(de)(de)(de)(de)那(nei)時(shi)候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)就(jiu)(jiu)小些(xie)，大(da)(da)標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)有(you)(you)充足(zu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)容(rong)(rong)量(liang)。相反，許(xu)多(duo)人用(yong)56w的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)替(ti)(ti)代(dai)72w的(de)(de)(de)(de)用(yong)起(qi)來也沒有(you)(you)什么難題(ti)，緣故是一(yi)(yi)般 電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器的(de)(de)(de)(de)設計方案留出一(yi)(yi)定的(de)(de)(de)(de)容(rong)(rong)量(liang)，負荷(he)輸(shu)出功(gong)(gong)率必須低于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)輸(shu)出功(gong)(gong)率，因此這類(lei)替(ti)(ti)代(dai)在(zai)(zai)一(yi)(yi)般應用(yong)上是行(xing)得通的(de)(de)(de)(de)，可是剩下的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)輸(shu)出功(gong)(gong)率容(rong)(rong)量(liang)就(jiu)(jiu)非常少了，一(yi)(yi)旦你(ni)的(de)(de)(de)(de)本(ben)(ben)(ben)子(zi)接了許(xu)多(duo)外接設備，例如二塊usb固態盤(pan)，隨(sui)(sui)后cpu飛速(su)運(yun)行(xing)，還有(you)(you)一(yi)(yi)個基(ji)座，上邊來個光(guang)驅飛速(su)讀盤(pan)，加上另外給電(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)，估算(suan)就(jiu)(jiu)風(feng)險了，要(yao)隨(sui)(sui)時(shi)隨(sui)(sui)地用(yong)手摸下你(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)是否早已能夠煮蛋了。因此盡量(liang)不要(yao)用(yong)小電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)替(ti)(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(yi)模一(yi)樣的設備，他人的電源(yuan)溫(wen)溫(wen)的，我的一(yi)直很燙(tang)，為何(he)?

　　先(xian)不(bu)必猜疑你(ni)的(de)(de)(de)電源不(bu)太好(hao)，先(xian)看(kan)一(yi)下你(ni)的(de)(de)(de)本子在干嘛，是否像上邊說的(de)(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(feng)狂(kuang)讀寫能力，光(guang)驅飛(fei)速(su)讀盤(pan)，另外給電池充電，高聲放(fang)著歌曲，顯(xian)示器(qi)亮度(du)較大(da)，無線網(wang)卡一(yi)直在探測數據信號這些，靈活運用電源管理方(fang)法，依據每日任務有效調節本子的(de)(de)(de)工(gong)作(zuo)態(tai)度(du)是很(hen)關鍵的(de)(de)(de)。

　　四、電(dian)源標稱電(dian)壓(ya)比我的本(ben)子充(chong)電(dian)電(dian)池電(dian)壓(ya)高許多，不容易(yi)出事了吧(ba)?

　　最先，要了解(jie)的是(shi)，電(dian)(dian)源(yuan)給本(ben)子供(gong)電(dian)(dian)系統與充電(dian)(dian)電(dian)(dian)池給本(ben)子供(gong)電(dian)(dian)系統是(shi)不一(yi)樣的。

　　充(chong)(chong)(chong)電(dian)電(dian)池(chi)供電(dian)系統，充(chong)(chong)(chong)電(dian)電(dian)池(chi)的輸出是(shi)純直流電(dian)，整(zheng)潔得(de)(de)很，充(chong)(chong)(chong)電(dian)電(dian)池(chi)的電(dian)壓(ya)(ya)既不太可(ke)能也(ye)不用(yong)設(she)計方案得(de)(de)很高，鋰電(dian)的有機化(hua)學特點(dian)決策了一(yi)節鋰電(dian)芯的輸出電(dian)壓(ya)(ya)只有在(zai)3.6V上下，因此(ci)許多充(chong)(chong)(chong)電(dian)電(dian)池(chi)全是(shi)選用(yong)三級(ji)串連的方法，10.8V也(ye)就變成很時興(xing)的充(chong)(chong)(chong)電(dian)電(dian)池(chi)電(dian)壓(ya)(ya)。一(yi)些充(chong)(chong)(chong)電(dian)電(dian)池(chi)的標(biao)稱值比(bi)3.6V的整(zheng)數倍稍(shao)大(da)一(yi)些，例如3.7V或是(shi)11.2V這些，實際上是(shi)以(yi)便維護充(chong)(chong)(chong)電(dian)電(dian)池(chi)。

　　電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統，狀況就(jiu)(jiu)繁雜(za)一(yi)些，最先(xian)必(bi)須(xu)對添加電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)開展進一(yi)步的(de)(de)(de)(de)(de)穩壓(ya)管濾波器(qi)，以確保(bao)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)特性不非(fei)常好的(de)(de)(de)(de)(de)狀況下平穩工(gong)作(zuo)中，穩壓(ya)管后的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)分為2個一(yi)部分，一(yi)路(lu)給(gei)本(ben)子工(gong)作(zuo)中供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統，另一(yi)路(lu)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，給(gei)本(ben)子供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統的(de)(de)(de)(de)(de)那(nei)(nei)一(yi)部分同(tong)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統的(de)(de)(de)(de)(de)那(nei)(nei)時候同(tong)樣(yang)，而給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)那(nei)(nei)一(yi)部分必(bi)須(xu)根據充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)回(hui)路(lu)才能夠(gou)加進鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上，控(kong)制(zhi)回(hui)路(lu)能夠(gou)很繁雜(za)，因此(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)務(wu)必(bi)超過鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)才有充(chong)(chong)足的(de)(de)(de)(de)(de)工(gong)作(zuo)能力供貨(huo)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)回(hui)路(lu)的(de)(de)(de)(de)(de)各模塊。最終真(zhen)實加進鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)絕不會就(jiu)(jiu)是你的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)標稱的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)。放心好了。
