電源適(shi)配器的(de)電(dian)磁干擾是很(hen)多(duo)人(ren)都頭疼的(de)問題，那(nei)么(me)電(dian)源適配器的(de)干擾如(ru)何解決?今天我們(men)一(yi)起來看一(yi)下(xia)!

　根據電(dian)磁兼(jian)容(rong)性產生的要素，解決電(dian)源適(shi)配器的電(dian)磁兼(jian)容(rong)性可從三個方面(mian)入手：

　　1、減小干(gan)擾(rao)源產生的干(gan)擾(rao)信號(hao)

　　2、切斷(duan)干擾信號(hao)的傳播途徑(jing)

　　3、增強受干擾體的(de)抗干擾能力

　　對(dui)電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器產生的(de)對(dui)外干(gan)擾(rao)，如電(dian)(dian)(dian)(dian)源(yuan)線諧波(bo)(bo)電(dian)(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)(dian)源(yuan)線傳導(dao)干(gan)擾(rao)、電(dian)(dian)(dian)(dian)磁場輻射干(gan)擾(rao)等(deng)，只能(neng)(neng)用(yong)減小干(gan)擾(rao)的(de)方法來解決。一(yi)方面，可(ke)以增強(qiang)輸入/輸出濾波(bo)(bo)電(dian)(dian)(dian)(dian)路的(de)設計，改(gai)善(shan)有源(yuan)功率因數補償(APFC)電(dian)(dian)(dian)(dian)路的(de)性能(neng)(neng)，減小開關管(guan)及整流(liu)、續流(liu)二極管(guan)的(de)電(dian)(dian)(dian)(dian)壓、電(dian)(dian)(dian)(dian)流(liu)變化率，采用(yong)各(ge)種軟開關電(dian)(dian)(dian)(dian)路拓(tuo)補結構及控制方式等(deng);另一(yi)方面，加強(qiang)機殼的(de)屏蔽(bi)效果，改(gai)善(shan)機殼的(de)縫隙(xi)泄露，并進(jin)行良好的(de)接地處理。

　　對外(wai)部的(de)(de)(de)(de)抗(kang)干(gan)(gan)擾(rao)能力，如浪涌、雷擊，應優(you)化(hua)交流輸(shu)入及直流輸(shu)出端口的(de)(de)(de)(de)防雷能力。對雷擊可采(cai)(cai)用氧化(hua)鋅壓(ya)(ya)敏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)與氣體放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)管(guan)等(deng)的(de)(de)(de)(de)組合方(fang)法(fa)來解決。對于靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，采(cai)(cai)用TVS管(guan)及相(xiang)應的(de)(de)(de)(de)接(jie)地(di)保護，加大小(xiao)(xiao)(xiao)信號(hao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)與機殼等(deng)的(de)(de)(de)(de)距離，或選用具有抗(kang)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)干(gan)(gan)擾(rao)的(de)(de)(de)(de)器件來解決。減(jian)(jian)(jian)(jian)小(xiao)(xiao)(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源適配器的(de)(de)(de)(de)內部干(gan)(gan)擾(rao)，應從以下幾個方(fang)面入手：注(zhu)(zhu)意數字(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)與模擬電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)單點(dian)接(jie)地(di)，大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)與小(xiao)(xiao)(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流特別是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)取樣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)單點(dian)接(jie)地(di)，以減(jian)(jian)(jian)(jian)小(xiao)(xiao)(xiao)共阻(zu)干(gan)(gan)擾(rao)、減(jian)(jian)(jian)(jian)小(xiao)(xiao)(xiao)地(di)環的(de)(de)(de)(de)影響;布(bu)線(xian)時注(zhu)(zhu)意相(xiang)鄰線(xian)間的(de)(de)(de)(de)間距及信號(hao)性(xing)質，避免產生串(chuan)擾(rao);減(jian)(jian)(jian)(jian)小(xiao)(xiao)(xiao)地(di)線(xian)阻(zu)抗(kang);減(jian)(jian)(jian)(jian)小(xiao)(xiao)(xiao)高(gao)壓(ya)(ya)大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流線(xian)路(lu)特別是變(bian)壓(ya)(ya)器原邊與開關管(guan)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源濾波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)所包圍的(de)(de)(de)(de)面積(ji);減(jian)(jian)(jian)(jian)小(xiao)(xiao)(xiao)輸(shu)出整流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)及續流二極管(guan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)與直流濾波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)所包圍的(de)(de)(de)(de)面積(ji);減(jian)(jian)(jian)(jian)小(xiao)(xiao)(xiao)變(bian)壓(ya)(ya)器的(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(rong)(rong)的(de)(de)(de)(de)分布(bu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong);采(cai)(cai)用諧(xie)振(zhen)頻率高(gao)的(de)(de)(de)(de)濾波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器等(deng)。

　　在傳(chuan)播途徑方面，適當(dang)的(de)(de)(de)增加高抗(kang)干擾(rao)能(neng)力的(de)(de)(de)TUS及高頻電(dian)(dian)(dian)容、鐵氧體磁珠(zhu)等元器(qi)件，以提(ti)高小(xiao)(xiao)信(xin)(xin)號(hao)電(dian)(dian)(dian)路的(de)(de)(de)抗(kang)干擾(rao)能(neng)力;與機(ji)殼距離較近(jin)的(de)(de)(de)小(xiao)(xiao)信(xin)(xin)號(hao)電(dian)(dian)(dian)路，應加適當(dang)的(de)(de)(de)絕緣耐壓(ya)處(chu)理(li)等;功率(lv)器(qi)件的(de)(de)(de)散(san)熱器(qi)、主變壓(ya)器(qi)的(de)(de)(de)電(dian)(dian)(dian)磁屏蔽(bi)層(ceng)要適當(dang)接地;各控制單元間的(de)(de)(de)大面積接地用(yong)接地板屏蔽(bi);在整(zheng)流器(qi)的(de)(de)(de)機(ji)架上(shang)，要考慮(lv)各整(zheng)流器(qi)間電(dian)(dian)(dian)磁耦合、整(zheng)機(ji)地線布置等，以改善電(dian)(dian)(dian)源(yuan)適配器(qi)內部工作的(de)(de)(de)穩(wen)定(ding)性(xing)。
