國(guó)創(chuàng)詳解lc濾波器

  LC濾波器一般指無(wú)源濾波器。lc濾波器是由電容、電感和電阻組成的濾波電路,又名“電源EMI濾波器”,或是“EMI電源濾波器”,一種無(wú)源雙向網(wǎng)絡(luò),它的一端是電源,另一端是負(fù)載。
  
  lc濾波器的原理就是電源濾波器輸入、輸出側(cè)與電源和負(fù)載側(cè)的阻抗適配越大,對(duì)電磁干擾的衰減就越有效。
  
  lc濾波器可以對(duì)電源線中特定頻率的頻點(diǎn)或該頻點(diǎn)以外的頻率進(jìn)行有效濾除,得到一個(gè)特定頻率的電源信號(hào),或消除一個(gè)特定頻率后的電源信號(hào)。
  
  到底濾波器有什么用,在多少錢(qián)的系統(tǒng)上才能發(fā)揮作用?有人說(shuō)加了濾波器以后聲場(chǎng)變窄了,說(shuō)要用再生電源,還有的說(shuō)要專(zhuān)門(mén)布音響線。總的來(lái)說(shuō)要看你使用的電源環(huán)境怎樣?本身就比較好的話(huà)濾波沒(méi)作用,可能還會(huì)反作用!環(huán)境差的話(huà)作用巨大!
  
  濾波用在電視機(jī)投影機(jī)貌似更多!線材不敢說(shuō),但是電源濾波肯定有用,低檔的有用的,起的是負(fù)面效果。
  
  lc濾波器曾經(jīng)因?yàn)閁SB解碼有明顯的噪音入過(guò)一個(gè),當(dāng)時(shí)以為是地線污染造成的后來(lái)給地線屏蔽了,還是有噪音,上了濾波器后的確有好轉(zhuǎn)。
  
  lc濾波器具有結(jié)構(gòu)簡(jiǎn)單、成本低廉、運(yùn)行可靠性較高、運(yùn)行費(fèi)用較低等優(yōu)點(diǎn),仍是被廣泛應(yīng)用諧波治理方面。
  
  以上就是國(guó)創(chuàng)總結(jié)的關(guān)于LC濾波器的詳細(xì)知識(shí),如果您想要了解更多關(guān)于濾波器的相關(guān)信息的話(huà),歡迎在線咨詢(xún)我們國(guó)創(chuàng)客服或是撥打服務(wù)熱線029-85251919進(jìn)行咨詢(xún),我們將竭誠(chéng)為您提供優(yōu)質(zhì)的服務(wù)!國(guó)創(chuàng)是一家專(zhuān)業(yè)從事半導(dǎo)體元器件、電源產(chǎn)品研發(fā)與生產(chǎn)的高新技術(shù)企業(yè),目前企業(yè)主營(yíng)產(chǎn)品有半導(dǎo)體器件、一體化電源、模塊電源等,并且提供專(zhuān)業(yè)的定制及配套服務(wù)!產(chǎn)品廣泛應(yīng)用于航天、航空、兵器、雷達(dá)、通信電臺(tái)、船舶、電子裝備等領(lǐng)域,專(zhuān)業(yè)的技術(shù)團(tuán)隊(duì),便捷的一站式配套服務(wù),與您共筑新藍(lán)圖。
