常見(jiàn)例句雙語(yǔ)例句The DC electromotive force output by AC generator can have quite big pulsating voltage.交流發(fā)電機(jī)輸出的直流電動(dòng)勢(shì)會(huì)有較大的脈動(dòng)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(jiǎn)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.採(cǎi)用三相不控整流的低壓大電流的AC/DC變換器，需要一級(jí)中間濾波器除去電壓脈動(dòng)，通常濾波器躰積重量都比較大。 返回 pulsating voltage
