電源適配器的幾個常見問題!

　　一、電(dian)(dian)源(yuan)(yuan)適配器(下稱(cheng)電(dian)(dian)源(yuan)(yuan))的標(biao)稱(cheng)電(dian)(dian)壓(ya)和電(dian)(dian)流代表(biao)什么(me)意思(si)?最(zui)先，一般(ban)電(dian)(dian)源(yuan)(yuan)標(biao)稱(cheng)的電(dian)(dian)壓(ya)，就是指引(yin)路輸出(chu)(chu)的電(dian)(dian)壓(ya)，也就是說(shuo)外邊不接一切負荷(he)，沒有電(dian)(dian)流輸出(chu)(chu)那時候的電(dian)(dian)壓(ya)，因此(ci)還可以了解為，此(ci)電(dian)(dian)壓(ya)就是說(shuo)電(dian)(dian)源(yuan)(yuan)輸出(chu)(chu)電(dian)(dian)壓(ya)的限制(zhi)。

　　針(zhen)對電(dian)源內(nei)部應用了積極穩(wen)(wen)壓(ya)(ya)管的(de)(de)元器(qi)件的(de)(de)狀況下，即便電(dian)壓(ya)(ya)電(dian)壓(ya)(ya)有一(yi)定的(de)(de)起伏(fu)，其輸出(chu)都是穩(wen)(wen)定值，像(xiang)目前市面上一(yi)般的(de)(de)小變電(dian)器(qi)，例如(ru)mp3播(bo)放器(qi)這類配的(de)(de)電(dian)源，假如(ru)電(dian)壓(ya)(ya)起伏(fu)，該電(dian)源的(de)(de)輸出(chu)也不容(rong)易隨著起伏(fu)的(de)(de)。

　　一(yi)般來(lai)講一(yi)般電源適配器(qi)的真實(shi)滿載電壓(ya)也不一(yi)定和(he)標稱電壓(ya)完全一(yi)致，由于電子元器(qi)件(jian)(jian)的特點不太可能(neng)完全一(yi)致，因(yin)此(ci)(ci)有一(yi)定的偏(pian)差(cha)，偏(pian)差(cha)越(yue)小，對電子元器(qi)件(jian)(jian)的一(yi)致性規(gui)定越(yue)高，制造(zao)的成本費就高了，因(yin)此(ci)(ci)價錢也就貴一(yi)些了。

　　此外，有(you)(you)關標稱的電(dian)(dian)流值(zhi)，不(bu)管一(yi)切(qie)電(dian)(dian)源常(chang)有(you)(you)一(yi)定的內(nei)電(dian)(dian)阻(zu)，因而當電(dian)(dian)源輸出電(dian)(dian)流的那時(shi)候，會在內(nei)部(bu)造成(cheng)壓力降，造成(cheng)倆件(jian)事兒，一(yi)個是造成(cheng)發(fa)熱量，因此電(dian)(dian)源會熱，另一(yi)個是造成(cheng)輸出電(dian)(dian)壓減少，等于(yu)內(nei)部(bu)耗費。

　　二(er)、全是一樣(yang)標稱(cheng)電(dian)壓的電(dian)源，輸出電(dian)流不一樣(yang)，能否用在同一臺(tai)本(ben)子上?

　　電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)壓一(yi)(yi)樣(yang)，輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不一(yi)(yi)樣(yang)，能否用(yong)在同一(yi)(yi)臺本(ben)(ben)子(zi)上(shang)。基礎的(de)(de)(de)(de)(de)(de)標(biao)(biao)(biao)準(zhun)是(shi)大(da)(da)(da)標(biao)(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)能夠替(ti)代(dai)(dai)小(xiao)標(biao)(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)。估算許多(duo)人(ren)會那樣(yang)想(xiang)，感覺大(da)(da)(da)標(biao)(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)會燒毀本(ben)(ben)子(zi)，由于電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)變大(da)(da)(da)嘛(ma)。事實上(shang)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)多(duo)少在電(dian)(dian)(dian)(dian)(dian)壓同樣(yang)的(de)(de)(de)(de)(de)(de)狀況(kuang)下(xia)在于負荷(he)，呵呵呵，想(xiang)一(yi)(yi)想(xiang)初級中學的(de)(de)(de)(de)(de)(de)物(wu)理學就知道(dao)。當本(ben)(ben)子(zi)長時(shi)間負荷(he)運行(xing)(xing)(xing)的(de)(de)(de)(de)(de)(de)那時(shi)候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)(da)(da)點，本(ben)(ben)子(zi)進到關(guan)機(ji)的(de)(de)(de)(de)(de)(de)那時(shi)候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)就小(xiao)些(xie)，大(da)(da)(da)標(biao)(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)有(you)充足的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)容(rong)量。相反，許多(duo)人(ren)用(yong)56w的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)替(ti)代(dai)(dai)72w的(de)(de)(de)(de)(de)(de)用(yong)起來也沒有(you)什么難(nan)題(ti)，緣故是(shi)一(yi)(yi)般(ban) 電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適配器的(de)(de)(de)(de)(de)(de)設計(ji)方案留出(chu)一(yi)(yi)定的(de)(de)(de)(de)(de)(de)容(rong)量，負荷(he)輸出(chu)功率必(bi)須(xu)低于電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)輸出(chu)功率，因(yin)此這類替(ti)代(dai)(dai)在一(yi)(yi)般(ban)應用(yong)上(shang)是(shi)行(xing)(xing)(xing)得(de)通的(de)(de)(de)(de)(de)(de)，可是(shi)剩(sheng)下(xia)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)輸出(chu)功率容(rong)量就非常少了(le)，一(yi)(yi)旦你的(de)(de)(de)(de)(de)(de)本(ben)(ben)子(zi)接了(le)許多(duo)外接設備(bei)，例如二塊(kuai)usb固態盤，隨(sui)后(hou)cpu飛速(su)(su)運行(xing)(xing)(xing)，還有(you)一(yi)(yi)個(ge)基座，上(shang)邊(bian)來個(ge)光驅(qu)飛速(su)(su)讀盤，加上(shang)另外給電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)，估算就風險了(le)，要隨(sui)時(shi)隨(sui)地(di)用(yong)手摸下(xia)你的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)是(shi)否早(zao)已能夠煮蛋了(le)。因(yin)此盡(jin)量不要用(yong)小(xiao)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)替(ti)代(dai)(dai)大(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)。

　　三、一模一樣的(de)設備，他人的(de)電源溫(wen)溫(wen)的(de)，我(wo)的(de)一直很燙，為何?

　　先不必猜疑你(ni)的電(dian)源(yuan)不太好，先看一下你(ni)的本子在干(gan)嘛，是(shi)(shi)否像(xiang)上邊說的二塊USB固態盤，CPU飛(fei)速(su)運(yun)行，固態盤瘋狂讀寫能力，光驅飛(fei)速(su)讀盤，另外給(gei)電(dian)池充電(dian)，高聲放著(zhu)歌(ge)曲(qu)，顯示器亮度較大(da)，無線(xian)網卡一直在探測數(shu)據信(xin)號這些，靈活運(yun)用電(dian)源(yuan)管(guan)理(li)方法，依據每日任務有效調節本子的工作態度是(shi)(shi)很關鍵(jian)的。

　　四、電(dian)源標稱電(dian)壓比我的本子充電(dian)電(dian)池電(dian)壓高許多(duo)，不容(rong)易出事了吧?

　　最先，要了(le)解的(de)是，電源給(gei)本子供電系統與(yu)充電電池給(gei)本子供電系統是不(bu)一樣的(de)。

　　充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)供電(dian)(dian)(dian)系統，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)輸出是純(chun)直(zhi)流電(dian)(dian)(dian)，整潔得很(hen)(hen)，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)既不太可能也不用設計(ji)方案得很(hen)(hen)高(gao)，鋰電(dian)(dian)(dian)的(de)(de)有機化(hua)學特點決策了一節鋰電(dian)(dian)(dian)芯的(de)(de)輸出電(dian)(dian)(dian)壓(ya)(ya)只(zhi)有在(zai)3.6V上下，因此(ci)許多充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)全是選用三(san)級串連的(de)(de)方法，10.8V也就變成很(hen)(hen)時興的(de)(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓(ya)(ya)。一些充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)標稱值比3.6V的(de)(de)整數(shu)倍稍大一些，例如3.7V或是11.2V這些，實際上是以便維護(hu)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)。

　　電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)，狀況就(jiu)繁(fan)雜一(yi)些，最(zui)先必須對添加(jia)(jia)(jia)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)開展進一(yi)步(bu)的(de)(de)穩(wen)壓(ya)(ya)(ya)管(guan)濾波器，以(yi)確保在電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)特(te)性不非常好(hao)的(de)(de)狀況下平穩(wen)工(gong)作(zuo)(zuo)中，穩(wen)壓(ya)(ya)(ya)管(guan)后的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)分為2個(ge)一(yi)部(bu)(bu)分，一(yi)路給本(ben)子(zi)工(gong)作(zuo)(zuo)中供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)，另(ling)一(yi)路給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，給本(ben)子(zi)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)的(de)(de)那一(yi)部(bu)(bu)分同(tong)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)的(de)(de)那時(shi)候(hou)同(tong)樣(yang)，而(er)給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)那一(yi)部(bu)(bu)分必須根據充(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)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制(zhi)(zhi)回(hui)路才(cai)能夠(gou)加(jia)(jia)(jia)進鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯上(shang)，控(kong)(kong)制(zhi)(zhi)回(hui)路能夠(gou)很繁(fan)雜，因此電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)務必超過鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)才(cai)有(you)充(chong)足(zu)的(de)(de)工(gong)作(zuo)(zuo)能力(li)供(gong)貨給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制(zhi)(zhi)回(hui)路的(de)(de)各(ge)模塊(kuai)。最(zui)終真(zhen)實(shi)加(jia)(jia)(jia)進鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)芯上(shang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)絕不會就(jiu)是你的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)標(biao)稱的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)。放心好(hao)了。
