　 AB變頻器輸出電抗器概述
變頻器專用輸出電抗器，是依靠線圈的感抗來阻礙電流變化的電器，抑制變頻器產生的高次諧波，其通常串聯于變頻器出線端和負載之間。

變頻器用到的電抗器有3種：輸入電抗器、輸出電抗器、直流電抗器。

1、輸入電抗器主要作用是抑制進線電源的網側諧波，增大進線電源主回路的短路阻抗。據此靈活考慮是否使用。
2、輸出電抗器主要作用是平衡出線電纜的分布容性負載，增大出線主回路的短路阻抗。并能抑制變頻器輸出的諧波，起到減小變頻器噪聲的作用。
兩臺以上變頻器并聯運行時，還起到限制換相環流和負荷平衡的作用。前者考慮電纜的長度而確定是否使用，后者則必須使用。
直流電抗器?主要用于公共直流母線型的交-直-交變頻傳動系統中。如果公共整流器的電流數學模型為感性負載，則必須使用；
如果是容性負載，則可以不用。不管哪種情況，使用直流電抗器都能起到抑制直流電流波動的作用。
AB變頻器輸出電抗器功能
1、降低工頻暫態過電壓，這是利用變頻器專用輸出電抗器的空載或輕負荷線路上的電容效應來實現的；
2、改善長輸電線路上的電壓分布；
3、緩解變頻器輸出端的三相不平衡現象,減輕線路上的能量損失;使輕負荷時線路中的無功功率盡可能就地平衡,防止無功功率不合理流動;
4、降低高壓母線上工頻穩態電壓,便于發電機同期并列;
5、防止發電機帶長線路可能出現的自勵磁諧振現象。
