電源適配器的干擾(rao)是很多(duo)人(ren)都頭(tou)疼的問題，那么電源適配器的干擾(rao)如何解決?今天我(wo)們(men)一起來(lai)看一下!

　　根(gen)據電(dian)磁兼(jian)(jian)容性產生的要素，解決電(dian)源適配(pei)器的電(dian)磁兼(jian)(jian)容性可從三個方面入手：

　　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(dui)電(dian)(dian)(dian)(dian)源適配器產生的對(dui)外干(gan)擾(rao)，如電(dian)(dian)(dian)(dian)源線諧波(bo)電(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)源線傳導干(gan)擾(rao)、電(dian)(dian)(dian)(dian)磁場輻射干(gan)擾(rao)等，只能(neng)用(yong)(yong)減(jian)小干(gan)擾(rao)的方法來解決。一(yi)方面，可以(yi)增(zeng)強輸(shu)入(ru)/輸(shu)出(chu)濾(lv)波(bo)電(dian)(dian)(dian)(dian)路(lu)(lu)的設計(ji)，改(gai)善(shan)有(you)源功率因數補償(APFC)電(dian)(dian)(dian)(dian)路(lu)(lu)的性(xing)能(neng)，減(jian)小開關管(guan)及整流、續流二極(ji)管(guan)的電(dian)(dian)(dian)(dian)壓、電(dian)(dian)(dian)(dian)流變化(hua)率，采用(yong)(yong)各種軟開關電(dian)(dian)(dian)(dian)路(lu)(lu)拓補結(jie)構(gou)及控制方式等;另一(yi)方面，加強機殼(ke)的屏蔽效果，改(gai)善(shan)機殼(ke)的縫隙(xi)泄露，并(bing)進行良好的接地處理。

　　對(dui)外部的(de)(de)(de)(de)抗(kang)(kang)干(gan)(gan)擾(rao)能力，如(ru)浪涌(yong)、雷(lei)擊，應(ying)優(you)化(hua)交流輸(shu)(shu)入及直流輸(shu)(shu)出端口的(de)(de)(de)(de)防雷(lei)能力。對(dui)雷(lei)擊可(ke)采(cai)(cai)用氧化(hua)鋅壓(ya)敏(min)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)與(yu)氣體放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)管等(deng)的(de)(de)(de)(de)組合方法(fa)來(lai)解決(jue)。對(dui)于靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，采(cai)(cai)用TVS管及相應(ying)的(de)(de)(de)(de)接(jie)(jie)地保護，加大小(xiao)信(xin)號(hao)(hao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)與(yu)機(ji)殼等(deng)的(de)(de)(de)(de)距離(li)，或選用具(ju)有抗(kang)(kang)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)干(gan)(gan)擾(rao)的(de)(de)(de)(de)器(qi)件(jian)來(lai)解決(jue)。減(jian)小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源適配器(qi)的(de)(de)(de)(de)內部干(gan)(gan)擾(rao)，應(ying)從(cong)以下幾個方面入手：注意(yi)數字電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)與(yu)模(mo)擬電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)單點接(jie)(jie)地，大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)與(yu)小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流特(te)別是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)取樣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)的(de)(de)(de)(de)單點接(jie)(jie)地，以減(jian)小(xiao)共阻(zu)干(gan)(gan)擾(rao)、減(jian)小(xiao)地環的(de)(de)(de)(de)影(ying)響;布線時注意(yi)相鄰線間(jian)的(de)(de)(de)(de)間(jian)距及信(xin)號(hao)(hao)性質，避免產生串擾(rao);減(jian)小(xiao)地線阻(zu)抗(kang)(kang);減(jian)小(xiao)高壓(ya)大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流線路(lu)(lu)(lu)(lu)特(te)別是(shi)變(bian)壓(ya)器(qi)原邊(bian)與(yu)開關(guan)管、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源濾波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)所包圍的(de)(de)(de)(de)面積(ji);減(jian)小(xiao)輸(shu)(shu)出整流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)及續流二(er)極管電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)與(yu)直流濾波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)所包圍的(de)(de)(de)(de)面積(ji);減(jian)小(xiao)變(bian)壓(ya)器(qi)的(de)(de)(de)(de)漏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感、濾波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容的(de)(de)(de)(de)分布電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容;采(cai)(cai)用諧振(zhen)頻率高的(de)(de)(de)(de)濾波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)等(deng)。

　　在傳播途徑方(fang)面，適(shi)當(dang)的(de)(de)(de)增加(jia)高抗(kang)干擾(rao)能力的(de)(de)(de)TUS及高頻電(dian)(dian)容、鐵氧體磁珠等元器(qi)件(jian)，以提高小信號電(dian)(dian)路的(de)(de)(de)抗(kang)干擾(rao)能力;與機殼距離較近的(de)(de)(de)小信號電(dian)(dian)路，應加(jia)適(shi)當(dang)的(de)(de)(de)絕(jue)緣耐壓處理等;功率器(qi)件(jian)的(de)(de)(de)散熱器(qi)、主變壓器(qi)的(de)(de)(de)電(dian)(dian)磁屏蔽(bi)層要適(shi)當(dang)接(jie)(jie)(jie)地;各控(kong)制單元間的(de)(de)(de)大面積接(jie)(jie)(jie)地用接(jie)(jie)(jie)地板(ban)屏蔽(bi);在整(zheng)流器(qi)的(de)(de)(de)機架上，要考慮各整(zheng)流器(qi)間電(dian)(dian)磁耦合、整(zheng)機地線布置(zhi)等，以改善電(dian)(dian)源適(shi)配器(qi)內部工(gong)作的(de)(de)(de)穩定性。
