title="電磁干擾濾波器">電磁干擾濾波器可以用于抑制傳導型電磁干擾噪聲。共模噪聲是通過使用雙重纏繞的環(huán)形電感來進行抑制的(LCM1和LCM2)。這些電感在單個鐵芯上的纏繞方式使得它們對每條交流電線上的同相共模噪聲表現(xiàn)出很高的阻抗。此外,Y電容(CY1和CY2)將高頻共模噪聲分流或分路到地。每條交流電線上的差模噪聲是通過2個X電容(CX1和CX2)來進行抑制的,這兩個電容趨向于將交流輸電線和中線之間存在的非同步高頻差模噪聲中和。在供電切斷之后,這些電容將通過輸入電阻進行放電。

需要額外濾波的情況

雖然所有交流或直流電源都帶有符合各種EMC標準的內部電磁干擾濾波器,但是有些情況下,使用這些電源的電路或系統(tǒng)其所產(chǎn)生的電噪聲遠遠超過濾波器自身的承受能力。在其他情況中,如果多個供電電源使用相同的交流電源,那么每個電源的內部電磁干擾濾波器所包含的或沒有濾除的少量噪聲會產(chǎn)生疊加,使噪聲超過可以承受的范圍。

此外,有時進入供電電源的交流輸電線帶有很多的噪聲,因此需要額外的電磁干擾濾波器。這種輸入噪聲可能以能量的尖峰或猝發(fā)脈沖形式存在。它可能是自然原因引起的,如雷雨,也可能是人為產(chǎn)生的,如所操作的某個工業(yè)設備含有大型的電動機、制動器、螺線管等。

在以上所有情況中,可能需要安裝外部或輔助電磁干擾濾波器,以便將電噪聲降低到可以接受的等級。這些電磁干擾的考慮事項適用于所有電子產(chǎn)品或系統(tǒng)的設計和安裝。標準的外部電磁干擾濾波器通常帶有單級LC電路,類似于圖1所示電路。較高性能的電磁干擾濾波可能需要兩級LC電路。此外,如果來自電動機或電擊的電尖峰會構成潛在威脅,就應該使用帶有高電壓脈沖衰減功能的電磁干擾濾波器。

電磁干擾濾波器規(guī)格

在選擇電磁干擾濾波器時,必須考慮許多規(guī)格和額定值。其中包括外殼大小、I/O連接、裝配類型、安全部門許可、工作電壓、工作電流(交流或直流安培)、泄露電流、隔離電阻、能承受的測試電壓、高壓脈沖或尖峰衰減、工作溫度范圍、直流電阻以及插入損耗

對于醫(yī)療應用而言,總裝配安裝后的泄漏電流以及可承受的測試電壓對于滿足患者安全有關的EMC 需求是非常重要的參數(shù)。這張插入損耗圖顯示了高性能電磁干擾濾波器中衰減隨頻率的變化。

電磁干擾濾波器的插入損耗信息如圖2所示,通常以圖表、圖形或表格的方式給出,它顯示了電磁干擾濾波器在工作范圍內衰減或抑制傳導型差模和共模噪聲的性能。

電磁兼容性測試

如上所述,大多數(shù)用于傳導型電磁干擾輻射的EMC 標準中所指定的常用頻率范圍都是150kHz~30MHz。為了確定某個電子器件滿足指定標準的限制,必須使用頻譜分析儀和線性阻抗穩(wěn)定網(wǎng)絡(LISN)進行測試。交流電源是通過LISN連接到待測設備的。LISN將測量阻抗標準化為50Ω并提供了到頻譜分析儀的隔離RF輸出,后者提供了來自設備的傳導發(fā)射的圖形。
