電源適配器的干擾是(shi)很多人都頭疼的問題(ti)，那(nei)么電(dian)源(yuan)適(shi)配器的干擾如何解決(jue)?今天(tian)我們(men)一起來看一下!

　　根據電(dian)磁(ci)兼容性(xing)產生的要素(su)，解決電(dian)源適配器的電(dian)磁(ci)兼容性(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)源(yuan)適配(pei)器(qi)產生的(de)對外(wai)干擾(rao)，如電(dian)(dian)(dian)(dian)源(yuan)線(xian)(xian)諧波(bo)電(dian)(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)(dian)源(yuan)線(xian)(xian)傳導干擾(rao)、電(dian)(dian)(dian)(dian)磁(ci)場(chang)輻(fu)射干擾(rao)等，只(zhi)能用(yong)減(jian)小干擾(rao)的(de)方(fang)法來解(jie)決(jue)。一方(fang)面(mian)，可以增強輸入/輸出濾波(bo)電(dian)(dian)(dian)(dian)路的(de)設計，改善有源(yuan)功率因(yin)數補(bu)償(APFC)電(dian)(dian)(dian)(dian)路的(de)性(xing)能，減(jian)小開關(guan)管及整流(liu)、續(xu)流(liu)二極管的(de)電(dian)(dian)(dian)(dian)壓、電(dian)(dian)(dian)(dian)流(liu)變化率，采(cai)用(yong)各(ge)種軟開關(guan)電(dian)(dian)(dian)(dian)路拓補(bu)結構及控制方(fang)式等;另一方(fang)面(mian)，加強機(ji)殼的(de)屏蔽效果，改善機(ji)殼的(de)縫隙泄露，并進行良好的(de)接地(di)處理。

　　對(dui)外部的(de)(de)(de)抗(kang)干擾能力，如浪涌(yong)、雷擊(ji)，應(ying)優化(hua)交流(liu)(liu)輸入及(ji)(ji)直流(liu)(liu)輸出(chu)(chu)端(duan)口的(de)(de)(de)防雷能力。對(dui)雷擊(ji)可采用(yong)氧化(hua)鋅(xin)壓(ya)(ya)(ya)敏電(dian)(dian)(dian)阻與(yu)氣體放電(dian)(dian)(dian)管等的(de)(de)(de)組合方(fang)法(fa)來(lai)解決。對(dui)于靜(jing)電(dian)(dian)(dian)放電(dian)(dian)(dian)，采用(yong)TVS管及(ji)(ji)相應(ying)的(de)(de)(de)接(jie)地保護，加大(da)小(xiao)(xiao)信號(hao)電(dian)(dian)(dian)路(lu)(lu)(lu)與(yu)機(ji)殼等的(de)(de)(de)距離，或選用(yong)具有(you)抗(kang)靜(jing)電(dian)(dian)(dian)干擾的(de)(de)(de)器件來(lai)解決。減(jian)(jian)(jian)(jian)小(xiao)(xiao)電(dian)(dian)(dian)源適配器的(de)(de)(de)內部干擾，應(ying)從以(yi)下幾(ji)個(ge)方(fang)面(mian)入手：注意數字(zi)電(dian)(dian)(dian)路(lu)(lu)(lu)與(yu)模(mo)擬(ni)電(dian)(dian)(dian)路(lu)(lu)(lu)單點(dian)接(jie)地，大(da)電(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)路(lu)(lu)(lu)與(yu)小(xiao)(xiao)電(dian)(dian)(dian)流(liu)(liu)特別(bie)(bie)是電(dian)(dian)(dian)流(liu)(liu)、電(dian)(dian)(dian)壓(ya)(ya)(ya)取(qu)樣電(dian)(dian)(dian)路(lu)(lu)(lu)的(de)(de)(de)單點(dian)接(jie)地，以(yi)減(jian)(jian)(jian)(jian)小(xiao)(xiao)共阻干擾、減(jian)(jian)(jian)(jian)小(xiao)(xiao)地環(huan)的(de)(de)(de)影響;布(bu)線(xian)時注意相鄰(lin)線(xian)間的(de)(de)(de)間距及(ji)(ji)信號(hao)性質，避免產生串擾;減(jian)(jian)(jian)(jian)小(xiao)(xiao)地線(xian)阻抗(kang);減(jian)(jian)(jian)(jian)小(xiao)(xiao)高壓(ya)(ya)(ya)大(da)電(dian)(dian)(dian)流(liu)(liu)線(xian)路(lu)(lu)(lu)特別(bie)(bie)是變(bian)壓(ya)(ya)(ya)器原邊與(yu)開關管、電(dian)(dian)(dian)源濾波(bo)電(dian)(dian)(dian)容電(dian)(dian)(dian)路(lu)(lu)(lu)所(suo)包(bao)圍的(de)(de)(de)面(mian)積;減(jian)(jian)(jian)(jian)小(xiao)(xiao)輸出(chu)(chu)整流(liu)(liu)電(dian)(dian)(dian)路(lu)(lu)(lu)及(ji)(ji)續流(liu)(liu)二極管電(dian)(dian)(dian)路(lu)(lu)(lu)與(yu)直流(liu)(liu)濾波(bo)電(dian)(dian)(dian)路(lu)(lu)(lu)所(suo)包(bao)圍的(de)(de)(de)面(mian)積;減(jian)(jian)(jian)(jian)小(xiao)(xiao)變(bian)壓(ya)(ya)(ya)器的(de)(de)(de)漏電(dian)(dian)(dian)感(gan)、濾波(bo)電(dian)(dian)(dian)容的(de)(de)(de)分布(bu)電(dian)(dian)(dian)容;采用(yong)諧振(zhen)頻率高的(de)(de)(de)濾波(bo)電(dian)(dian)(dian)容器等。

　　在(zai)傳播(bo)途徑方面(mian)，適(shi)當的(de)(de)增加(jia)高抗(kang)(kang)干擾(rao)能力(li)(li)的(de)(de)TUS及高頻電(dian)容、鐵氧體磁(ci)珠(zhu)等元(yuan)器(qi)件(jian)(jian)，以提(ti)高小信號(hao)電(dian)路(lu)的(de)(de)抗(kang)(kang)干擾(rao)能力(li)(li);與機殼距離較近的(de)(de)小信號(hao)電(dian)路(lu)，應(ying)加(jia)適(shi)當的(de)(de)絕緣耐壓(ya)處理等;功率器(qi)件(jian)(jian)的(de)(de)散熱器(qi)、主變(bian)壓(ya)器(qi)的(de)(de)電(dian)磁(ci)屏蔽層要適(shi)當接地(di);各控(kong)制單元(yuan)間(jian)的(de)(de)大面(mian)積接地(di)用接地(di)板(ban)屏蔽;在(zai)整流器(qi)的(de)(de)機架上，要考慮各整流器(qi)間(jian)電(dian)磁(ci)耦合、整機地(di)線布置(zhi)等，以改(gai)善電(dian)源適(shi)配器(qi)內部(bu)工作的(de)(de)穩定(ding)性。
