電源適配器的(de)干擾是(shi)很多人都頭(tou)疼的(de)問題，那(nei)么電源(yuan)適配器的(de)干擾如何解決?今天我們一起來看一下!

　　根據電磁兼容性產生的要素，解(jie)決電源(yuan)適配器(qi)的電磁兼容性可(ke)從三(san)個方面入手：

　　1、減小干擾源產生的干擾信號

　　2、切斷干擾信號的傳播途徑

　　3、增強受干擾體的抗干擾能力

　　對電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器產生的(de)(de)(de)(de)對外干擾，如電(dian)(dian)(dian)源(yuan)(yuan)線諧波(bo)(bo)電(dian)(dian)(dian)流、電(dian)(dian)(dian)源(yuan)(yuan)線傳導干擾、電(dian)(dian)(dian)磁場輻(fu)射干擾等，只能(neng)用減小(xiao)干擾的(de)(de)(de)(de)方法(fa)來(lai)解決(jue)。一(yi)方面，可以增(zeng)強(qiang)輸入/輸出濾波(bo)(bo)電(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)設(she)計，改善有(you)源(yuan)(yuan)功率因數補償(APFC)電(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)性能(neng)，減小(xiao)開關管及(ji)整(zheng)流、續流二極管的(de)(de)(de)(de)電(dian)(dian)(dian)壓、電(dian)(dian)(dian)流變化率，采用各種軟(ruan)開關電(dian)(dian)(dian)路(lu)拓補結構及(ji)控制方式等;另一(yi)方面，加強(qiang)機(ji)殼的(de)(de)(de)(de)屏蔽效果，改善機(ji)殼的(de)(de)(de)(de)縫(feng)隙泄露，并進行良好的(de)(de)(de)(de)接地處理。

　　對(dui)外(wai)部(bu)(bu)的(de)(de)抗(kang)干(gan)(gan)擾(rao)能力，如(ru)浪(lang)涌、雷(lei)擊(ji)，應優化交流輸(shu)入及直(zhi)流輸(shu)出端口的(de)(de)防(fang)雷(lei)能力。對(dui)雷(lei)擊(ji)可采用(yong)(yong)氧化鋅壓(ya)敏(min)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)與氣(qi)體(ti)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)管(guan)等的(de)(de)組合(he)方(fang)法來(lai)解決(jue)。對(dui)于靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，采用(yong)(yong)TVS管(guan)及相(xiang)應的(de)(de)接地(di)(di)(di)保(bao)護，加(jia)大小(xiao)(xiao)(xiao)信號(hao)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)與機殼等的(de)(de)距離，或選(xuan)用(yong)(yong)具有(you)抗(kang)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)干(gan)(gan)擾(rao)的(de)(de)器(qi)(qi)件(jian)來(lai)解決(jue)。減(jian)小(xiao)(xiao)(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)源適配器(qi)(qi)的(de)(de)內部(bu)(bu)干(gan)(gan)擾(rao)，應從以(yi)下(xia)幾個方(fang)面入手：注意數字電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)與模擬電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)單點(dian)接地(di)(di)(di)，大電(dian)(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)與小(xiao)(xiao)(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)流特(te)別是電(dian)(dian)(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)取樣電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)單點(dian)接地(di)(di)(di)，以(yi)減(jian)小(xiao)(xiao)(xiao)共阻(zu)干(gan)(gan)擾(rao)、減(jian)小(xiao)(xiao)(xiao)地(di)(di)(di)環的(de)(de)影響;布(bu)線(xian)時注意相(xiang)鄰線(xian)間(jian)的(de)(de)間(jian)距及信號(hao)性質，避免(mian)產(chan)生串擾(rao);減(jian)小(xiao)(xiao)(xiao)地(di)(di)(di)線(xian)阻(zu)抗(kang);減(jian)小(xiao)(xiao)(xiao)高壓(ya)大電(dian)(dian)(dian)(dian)(dian)(dian)流線(xian)路(lu)(lu)特(te)別是變壓(ya)器(qi)(qi)原邊與開(kai)關管(guan)、電(dian)(dian)(dian)(dian)(dian)(dian)源濾波(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)所包(bao)圍的(de)(de)面積(ji);減(jian)小(xiao)(xiao)(xiao)輸(shu)出整流電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)及續流二極管(guan)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)與直(zhi)流濾波(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)所包(bao)圍的(de)(de)面積(ji);減(jian)小(xiao)(xiao)(xiao)變壓(ya)器(qi)(qi)的(de)(de)漏電(dian)(dian)(dian)(dian)(dian)(dian)感、濾波(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)分布(bu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong);采用(yong)(yong)諧振頻率高的(de)(de)濾波(bo)(bo)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)等。

　　在(zai)傳播途(tu)徑(jing)方面，適(shi)當的(de)增加高(gao)抗干擾(rao)能力(li)的(de)TUS及高(gao)頻電容、鐵氧體(ti)磁珠等(deng)(deng)元器(qi)(qi)(qi)(qi)件(jian)，以提高(gao)小信(xin)號(hao)電路的(de)抗干擾(rao)能力(li);與機(ji)殼距離較近的(de)小信(xin)號(hao)電路，應加適(shi)當的(de)絕緣耐(nai)壓處理(li)等(deng)(deng);功(gong)率器(qi)(qi)(qi)(qi)件(jian)的(de)散熱器(qi)(qi)(qi)(qi)、主(zhu)變壓器(qi)(qi)(qi)(qi)的(de)電磁屏(ping)(ping)蔽(bi)層要適(shi)當接地(di);各控制單元間(jian)的(de)大面積接地(di)用(yong)接地(di)板屏(ping)(ping)蔽(bi);在(zai)整(zheng)流器(qi)(qi)(qi)(qi)的(de)機(ji)架上(shang)，要考慮各整(zheng)流器(qi)(qi)(qi)(qi)間(jian)電磁耦合、整(zheng)機(ji)地(di)線布(bu)置(zhi)等(deng)(deng)，以改善電源適(shi)配器(qi)(qi)(qi)(qi)內(nei)部工作的(de)穩定(ding)性。

　　對于電(dian)源適配器的干擾如何解決想必(bi)大(da)家(jia)已經簡單了解了，希望大(da)家(jia)遇(yu)到這個(ge)問題的時候可以順利(li)解決!
