常見例句雙語例句The DC electromotive force output by AC generator can have quite big pulsating voltage.交流發(fā)電機輸出的直流電動勢會有較大的脈動電壓。A medium frequency, middle-voltage and square wave pulsating power source is put forward.本文介紹了一種中頻中壓方波脈沖電源，簡要敘述了它的原理和電路。Low voltage-high current AC/DC converter using three-phase uncontrolled rectifier needs a medium filter to remove pulsating voltage. Usually the filter is heavy and huge.采用三相不控整流的低壓大電流的AC/DC變換器，需要一級中間濾波器除去電壓脈動，通常濾波器體積重量都比較大。 返回 pulsating voltage
