電源適配器的幾個常見問題!
電源適配器的幾個常見問題!
一、電(dian)(dian)(dian)源適配器(下(xia)稱(cheng)電(dian)(dian)(dian)源)的(de)標稱(cheng)電(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)流代表什么意思?最先,一般電(dian)(dian)(dian)源標稱(cheng)的(de)電(dian)(dian)(dian)壓(ya),就是指引路輸(shu)出的(de)電(dian)(dian)(dian)壓(ya),也就是說外邊(bian)不接一切負(fu)荷,沒(mei)有電(dian)(dian)(dian)流輸(shu)出那時(shi)候的(de)電(dian)(dian)(dian)壓(ya),因此(ci)還可以了解為,此(ci)電(dian)(dian)(dian)壓(ya)就是說電(dian)(dian)(dian)源輸(shu)出電(dian)(dian)(dian)壓(ya)的(de)限制。
針對(dui)電(dian)(dian)源(yuan)內部應用了積(ji)極穩壓(ya)管的元器(qi)件的狀(zhuang)況下,即便電(dian)(dian)壓(ya)電(dian)(dian)壓(ya)有一定的起(qi)伏,其輸出(chu)都是穩定值,像目(mu)前市面上一般的小變(bian)電(dian)(dian)器(qi),例(li)如(ru)mp3播放(fang)器(qi)這類配的電(dian)(dian)源(yuan),假如(ru)電(dian)(dian)壓(ya)起(qi)伏,該電(dian)(dian)源(yuan)的輸出(chu)也不容易隨(sui)著起(qi)伏的。
一(yi)般來講一(yi)般電(dian)(dian)(dian)源適配(pei)器的(de)真(zhen)實滿(man)載電(dian)(dian)(dian)壓也不一(yi)定和標稱電(dian)(dian)(dian)壓完(wan)全(quan)一(yi)致,由于(yu)電(dian)(dian)(dian)子(zi)元器件(jian)的(de)特點不太(tai)可能完(wan)全(quan)一(yi)致,因此有一(yi)定的(de)偏(pian)差,偏(pian)差越(yue)(yue)小,對電(dian)(dian)(dian)子(zi)元器件(jian)的(de)一(yi)致性規定越(yue)(yue)高,制造的(de)成本費就高了,因此價錢也就貴一(yi)些了。
此(ci)外,有關標稱的(de)電(dian)(dian)(dian)(dian)流(liu)值,不管一(yi)切電(dian)(dian)(dian)(dian)源常有一(yi)定的(de)內電(dian)(dian)(dian)(dian)阻,因而當(dang)電(dian)(dian)(dian)(dian)源輸出(chu)電(dian)(dian)(dian)(dian)流(liu)的(de)那時候,會在內部造(zao)(zao)成壓(ya)(ya)力(li)降(jiang),造(zao)(zao)成倆件(jian)事兒,一(yi)個是造(zao)(zao)成發(fa)熱(re)(re)量,因此(ci)電(dian)(dian)(dian)(dian)源會熱(re)(re),另(ling)一(yi)個是造(zao)(zao)成輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)減(jian)少(shao),等于內部耗費。
二、全是一樣(yang)(yang)標稱電壓的電源(yuan),輸出電流(liu)不一樣(yang)(yang),能否用在同一臺本子上?
電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓一(yi)(yi)樣(yang),輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)不(bu)一(yi)(yi)樣(yang),能(neng)否(fou)用(yong)在同一(yi)(yi)臺本子上(shang)。基(ji)礎的(de)(de)(de)(de)標(biao)準是(shi)(shi)(shi)大標(biao)稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)能(neng)夠(gou)替代小(xiao)(xiao)標(biao)稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)。估(gu)算許多人會那樣(yang)想,感覺大標(biao)稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)會燒(shao)毀本子,由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)變大嘛。事(shi)實(shi)上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)多少在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓同樣(yang)的(de)(de)(de)(de)狀況下(xia)在于(yu)負(fu)荷,呵呵呵,想一(yi)(yi)想初級中學的(de)(de)(de)(de)物理學就知道。當(dang)本子長時間負(fu)荷運行(xing)(xing)的(de)(de)(de)(de)那時候(hou),電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)大點,本子進到關機的(de)(de)(de)(de)那時候(hou),電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)就小(xiao)(xiao)些,大標(biao)稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)有充足的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)容量(liang)。相反,許多人用(yong)56w的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)替代72w的(de)(de)(de)(de)用(yong)起來(lai)(lai)也沒有什(shen)么難題(ti),緣故是(shi)(shi)(shi)一(yi)(yi)般 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配器(qi)的(de)(de)(de)(de)設計方案留(liu)出一(yi)(yi)定(ding)的(de)(de)(de)(de)容量(liang),負(fu)荷輸(shu)出功率(lv)(lv)必須低于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)輸(shu)出功率(lv)(lv),因此這類替代在一(yi)(yi)般應用(yong)上(shang)是(shi)(shi)(shi)行(xing)(xing)得通的(de)(de)(de)(de),可是(shi)(shi)(shi)剩下(xia)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)輸(shu)出功率(lv)(lv)容量(liang)就非常少了(le),一(yi)(yi)旦你(ni)的(de)(de)(de)(de)本子接了(le)許多外(wai)接設備(bei),例(li)如(ru)二(er)塊usb固態盤,隨后cpu飛速運行(xing)(xing),還有一(yi)(yi)個(ge)基(ji)座(zuo),上(shang)邊來(lai)(lai)個(ge)光驅飛速讀盤,加上(shang)另外(wai)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian),估(gu)算就風險了(le),要隨時隨地用(yong)手摸下(xia)你(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)是(shi)(shi)(shi)否(fou)早(zao)已(yi)能(neng)夠(gou)煮蛋了(le)。因此盡量(liang)不(bu)要用(yong)小(xiao)(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)替代大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)。
三、一模一樣的設(she)備,他人(ren)的電源(yuan)溫(wen)溫(wen)的,我的一直很燙(tang),為何(he)?
先不必猜疑你的(de)電源不太(tai)好,先看一下你的(de)本子(zi)(zi)在干(gan)嘛,是否像上邊說的(de)二塊USB固(gu)態盤,CPU飛(fei)速運行(xing),固(gu)態盤瘋(feng)狂讀(du)寫(xie)能(neng)力,光驅飛(fei)速讀(du)盤,另外給電池(chi)充電,高(gao)聲(sheng)放著(zhu)歌曲,顯示器亮度較大(da),無線網(wang)卡一直在探(tan)測數據信號這些,靈活(huo)運用電源管(guan)理方法,依據每(mei)日任務有效(xiao)調節本子(zi)(zi)的(de)工(gong)作態度是很關鍵的(de)。
四(si)、電(dian)(dian)源標稱電(dian)(dian)壓比我的本(ben)子充電(dian)(dian)電(dian)(dian)池電(dian)(dian)壓高許多,不容易(yi)出事了吧?
最先,要了解的是(shi)(shi),電源給本子供電系(xi)統與(yu)充電電池(chi)給本子供電系(xi)統是(shi)(shi)不一(yi)樣的。
充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)供電(dian)(dian)(dian)(dian)系統(tong),充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)輸(shu)出(chu)是純直(zhi)流電(dian)(dian)(dian)(dian),整(zheng)潔得(de)很(hen)(hen),充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓既(ji)不太可能也(ye)不用設計方案得(de)很(hen)(hen)高,鋰電(dian)(dian)(dian)(dian)的(de)(de)(de)有(you)機化學特點(dian)決策了一(yi)節鋰電(dian)(dian)(dian)(dian)芯的(de)(de)(de)輸(shu)出(chu)電(dian)(dian)(dian)(dian)壓只(zhi)有(you)在(zai)3.6V上(shang)(shang)下,因此(ci)許(xu)多(duo)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)全(quan)是選用三級串連的(de)(de)(de)方法,10.8V也(ye)就變成(cheng)很(hen)(hen)時(shi)興(xing)的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)壓。一(yi)些(xie)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)標(biao)稱(cheng)值比3.6V的(de)(de)(de)整(zheng)數倍稍大一(yi)些(xie),例如3.7V或是11.2V這(zhe)些(xie),實際上(shang)(shang)是以(yi)便維(wei)護充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。
電(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)系統,狀(zhuang)況就(jiu)繁(fan)雜(za)一些,最(zui)先必(bi)須對添(tian)加(jia)電(dian)(dian)(dian)壓(ya)開展進(jin)一步的(de)穩(wen)壓(ya)管濾(lv)波器,以確(que)保在(zai)電(dian)(dian)(dian)源(yuan)特(te)性不(bu)非常好(hao)的(de)狀(zhuang)況下平(ping)穩(wen)工作(zuo)中,穩(wen)壓(ya)管后的(de)電(dian)(dian)(dian)壓(ya)分(fen)為2個(ge)一部(bu)分(fen),一路(lu)(lu)(lu)給(gei)本子工作(zuo)中供電(dian)(dian)(dian)系統,另(ling)一路(lu)(lu)(lu)給(gei)電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian),給(gei)本子供電(dian)(dian)(dian)系統的(de)那一部(bu)分(fen)同充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池供電(dian)(dian)(dian)系統的(de)那時(shi)候(hou)同樣,而(er)給(gei)電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)的(de)那一部(bu)分(fen)必(bi)須根據(ju)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)控制(zhi)回(hui)路(lu)(lu)(lu)才能夠加(jia)進(jin)鋰電(dian)(dian)(dian)芯上,控制(zhi)回(hui)路(lu)(lu)(lu)能夠很(hen)繁(fan)雜(za),因此電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)務必(bi)超過(guo)鋰電(dian)(dian)(dian)芯電(dian)(dian)(dian)壓(ya)才有充(chong)(chong)足的(de)工作(zuo)能力供貨給(gei)電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)控制(zhi)回(hui)路(lu)(lu)(lu)的(de)各模塊。最(zui)終真實加(jia)進(jin)鋰電(dian)(dian)(dian)芯上的(de)電(dian)(dian)(dian)壓(ya)絕不(bu)會就(jiu)是你(ni)的(de)電(dian)(dian)(dian)源(yuan)標稱的(de)電(dian)(dian)(dian)壓(ya)。放心好(hao)了(le)。
