在(zai)生(sheng)活中，我們往往用(yong)(yong)到很多電(dian)(dian)(dian)(dian)源適(shi)配器(qi)(qi)，比如(ru)手機充電(dian)(dian)(dian)(dian)器(qi)(qi)、WiFi路由器(qi)(qi)用(yong)(yong)電(dian)(dian)(dian)(dian)源適(shi)配器(qi)(qi)、電(dian)(dian)(dian)(dian)子(zi)琴(qin)用(yong)(yong)電(dian)(dian)(dian)(dian)源適(shi)配器(qi)(qi)，筆記本(ben)用(yong)(yong)電(dian)(dian)(dian)(dian)源適(shi)配器(qi)(qi)等。哪些(xie)是線性電(dian)(dian)(dian)(dian)源適(shi)配器(qi)(qi)，哪些(xie)是開關(guan)電源適(shi)配器呢(ni)？線(xian)性(xing)電源適配器又有哪些優點和缺(que)點？今天飛(fei)天鷹科技來為大家(jia)解答。

線性(xing)電源(yuan)適(shi)配器的優點(dian)：

線性(xing)電源技術(shu)是最(zui)早的電源技術(shu)，很成熟，制作成本較(jiao)低(di)，可以達(da)到很高的穩定度，波紋(wen)較(jiao)小，自身的干(gan)擾和(he)噪(zao)聲都(dou)比較(jiao)小。

線性電(dian)源適(shi)配(pei)器的缺點：

因為工作(zuo)在(zai)工頻(50Hz),變(bian)壓(ya)器的(de)體(ti)積比(bi)較大(da),效率(lv)偏低(一般滿(man)載工作(zuo)的(de)效率(lv)只有80%左右)整體(ti)體(ti)積較大(da)，顯(xian)得較笨重(zhong).且輸入電壓(ya)范圍要求高，一旦(dan)市電寬幅變(bian)化不(bu)穩定就容易導致(zhi)直(zhi)流輸出達不(bu)到設計要求。

線(xian)性(xing)電(dian)(dian)源(yuan)適配(pei)器(qi)的(de)(de)(de)缺點很(hen)多，但是(shi)(shi)(shi)優點也很(hen)明顯。因其低(di)(di)紋(wen)波，低(di)(di)噪聲(sheng)的(de)(de)(de)特性(xing)，很(hen)多對電(dian)(dian)源(yuan)噪聲(sheng)敏感的(de)(de)(de)設備(bei)(bei)往往采用線(xian)性(xing)電(dian)(dian)源(yuan)適配(pei)器(qi)，比如(ru)電(dian)(dian)子琴、電(dian)(dian)吉他等樂器(qi)，一些(xie)對信號(hao)敏感的(de)(de)(de)小型醫(yi)療設備(bei)(bei)等。在實際購買這些(xie)設備(bei)(bei)的(de)(de)(de)時(shi)候我們(men)(men)也可以通過觀察電(dian)(dian)源(yuan)適配(pei)器(qi)是(shi)(shi)(shi)否重，是(shi)(shi)(shi)否大，是(shi)(shi)(shi)否發熱，是(shi)(shi)(shi)否有散熱孔來判斷(duan)它是(shi)(shi)(shi)否采用的(de)(de)(de)是(shi)(shi)(shi)線(xian)性(xing)電(dian)(dian)源(yuan)適配(pei)器(qi)，如(ru)果不是(shi)(shi)(shi)，我們(men)(men)就得考慮是(shi)(shi)(shi)否值得購買了。
