電源適配器的(de)干(gan)擾是很多人都頭疼的(de)問題，那(nei)么電(dian)源適配器的(de)干(gan)擾如何解決?今天我們一(yi)(yi)起(qi)來看一(yi)(yi)下!

　　根據電(dian)磁兼(jian)容(rong)性(xing)產生的要(yao)素，解(jie)決電(dian)源適配器的電(dian)磁兼(jian)容(rong)性(xing)可從三(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)(dian)(dian)源(yuan)適配器產生的對外(wai)干(gan)(gan)擾，如電(dian)(dian)(dian)(dian)(dian)源(yuan)線諧波電(dian)(dian)(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)(dian)(dian)源(yuan)線傳導干(gan)(gan)擾、電(dian)(dian)(dian)(dian)(dian)磁場(chang)輻(fu)射干(gan)(gan)擾等(deng)，只能用減(jian)小(xiao)干(gan)(gan)擾的方法來解決(jue)。一(yi)方面，可以增(zeng)強輸入/輸出濾波電(dian)(dian)(dian)(dian)(dian)路(lu)的設(she)計，改善(shan)有(you)源(yuan)功(gong)率(lv)因數補償(APFC)電(dian)(dian)(dian)(dian)(dian)路(lu)的性能，減(jian)小(xiao)開關(guan)管及整(zheng)流(liu)、續流(liu)二極管的電(dian)(dian)(dian)(dian)(dian)壓、電(dian)(dian)(dian)(dian)(dian)流(liu)變化(hua)率(lv)，采用各種(zhong)軟開關(guan)電(dian)(dian)(dian)(dian)(dian)路(lu)拓補結(jie)構及控(kong)制方式等(deng);另一(yi)方面，加(jia)強機殼(ke)的屏蔽(bi)效果，改善(shan)機殼(ke)的縫隙泄露(lu)，并進行良好的接地處(chu)理。

　　對外部的(de)(de)抗(kang)干(gan)擾(rao)能(neng)力，如浪涌、雷(lei)擊，應優化(hua)交流輸入(ru)及(ji)直(zhi)流輸出(chu)端口的(de)(de)防雷(lei)能(neng)力。對雷(lei)擊可(ke)采(cai)(cai)(cai)用(yong)(yong)氧化(hua)鋅壓(ya)敏電(dian)(dian)(dian)(dian)(dian)阻與(yu)氣體放電(dian)(dian)(dian)(dian)(dian)管(guan)(guan)等(deng)(deng)的(de)(de)組合方法(fa)來解決。對于靜電(dian)(dian)(dian)(dian)(dian)放電(dian)(dian)(dian)(dian)(dian)，采(cai)(cai)(cai)用(yong)(yong)TVS管(guan)(guan)及(ji)相應的(de)(de)接地(di)保護，加(jia)大(da)(da)小(xiao)信號電(dian)(dian)(dian)(dian)(dian)路(lu)與(yu)機殼(ke)等(deng)(deng)的(de)(de)距離(li)，或選用(yong)(yong)具有抗(kang)靜電(dian)(dian)(dian)(dian)(dian)干(gan)擾(rao)的(de)(de)器(qi)件(jian)來解決。減(jian)(jian)小(xiao)電(dian)(dian)(dian)(dian)(dian)源適(shi)配器(qi)的(de)(de)內部干(gan)擾(rao)，應從以下幾個方面(mian)入(ru)手(shou)：注(zhu)意數字(zi)電(dian)(dian)(dian)(dian)(dian)路(lu)與(yu)模(mo)擬電(dian)(dian)(dian)(dian)(dian)路(lu)單點接地(di)，大(da)(da)電(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)(dian)路(lu)與(yu)小(xiao)電(dian)(dian)(dian)(dian)(dian)流特(te)別(bie)(bie)是(shi)電(dian)(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)(dian)壓(ya)取樣(yang)電(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)單點接地(di)，以減(jian)(jian)小(xiao)共阻干(gan)擾(rao)、減(jian)(jian)小(xiao)地(di)環的(de)(de)影響;布線時(shi)注(zhu)意相鄰線間(jian)的(de)(de)間(jian)距及(ji)信號性質(zhi)，避免產(chan)生串(chuan)擾(rao);減(jian)(jian)小(xiao)地(di)線阻抗(kang);減(jian)(jian)小(xiao)高壓(ya)大(da)(da)電(dian)(dian)(dian)(dian)(dian)流線路(lu)特(te)別(bie)(bie)是(shi)變(bian)壓(ya)器(qi)原邊與(yu)開(kai)關(guan)管(guan)(guan)、電(dian)(dian)(dian)(dian)(dian)源濾(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)容(rong)電(dian)(dian)(dian)(dian)(dian)路(lu)所(suo)包(bao)圍(wei)的(de)(de)面(mian)積;減(jian)(jian)小(xiao)輸出(chu)整(zheng)流電(dian)(dian)(dian)(dian)(dian)路(lu)及(ji)續(xu)流二極管(guan)(guan)電(dian)(dian)(dian)(dian)(dian)路(lu)與(yu)直(zhi)流濾(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)路(lu)所(suo)包(bao)圍(wei)的(de)(de)面(mian)積;減(jian)(jian)小(xiao)變(bian)壓(ya)器(qi)的(de)(de)漏電(dian)(dian)(dian)(dian)(dian)感、濾(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)容(rong)的(de)(de)分(fen)布電(dian)(dian)(dian)(dian)(dian)容(rong);采(cai)(cai)(cai)用(yong)(yong)諧振頻率高的(de)(de)濾(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)等(deng)(deng)。

　　在(zai)傳(chuan)播途徑方面(mian)，適(shi)當的(de)(de)增加(jia)高(gao)抗干擾能力(li)的(de)(de)TUS及高(gao)頻(pin)電容、鐵氧體磁珠等(deng)元器(qi)件，以(yi)(yi)提高(gao)小信(xin)(xin)號電路(lu)的(de)(de)抗干擾能力(li);與機殼距離較近的(de)(de)小信(xin)(xin)號電路(lu)，應加(jia)適(shi)當的(de)(de)絕緣耐壓(ya)(ya)處理等(deng);功率器(qi)件的(de)(de)散(san)熱器(qi)、主變壓(ya)(ya)器(qi)的(de)(de)電磁屏(ping)蔽層要適(shi)當接(jie)地;各控(kong)制單元間的(de)(de)大面(mian)積接(jie)地用接(jie)地板屏(ping)蔽;在(zai)整流(liu)(liu)器(qi)的(de)(de)機架上，要考慮各整流(liu)(liu)器(qi)間電磁耦合、整機地線布(bu)置等(deng)，以(yi)(yi)改(gai)善電源適(shi)配器(qi)內(nei)部工(gong)作的(de)(de)穩定性。
