Mutualtrol Dynamatic Eaton Cutler Hammer 15-235-101（1）運(yùn)算電路：將外部的速度、轉(zhuǎn)矩等指令同檢測(cè)電路的電流、電壓信號(hào)進(jìn)行比較運(yùn)算，決定逆變器的輸出電壓、頻率。
（2）電壓、電流檢測(cè)電路：與主回路電位隔離檢測(cè)電壓、電流等。
（3）驅(qū)動(dòng)電路：驅(qū)動(dòng)主電路器件的電路。它與控制電路隔離使主電路器件導(dǎo)通、關(guān)斷。
（4）速度檢測(cè)電路:以裝在異步電動(dòng)機(jī)軸機(jī)上的速度檢測(cè)器(tg、plg等)的信號(hào)為速度信號(hào)，送入運(yùn)算回路，根據(jù)指令和運(yùn)算可使電動(dòng)機(jī)按指令速度運(yùn)轉(zhuǎn)。
（5）保護(hù)電路：檢測(cè)主電路的電壓、電流等，當(dāng)發(fā)生過(guò)載或過(guò)電壓等異常時(shí)，為了防止逆變器和異步電動(dòng)機(jī)損壞，使逆變器停止工作或抑制電壓、電流值。逆變器
同整流器相反，逆變器是將直流功率變換為所要求頻率的交流功率，以所確定的時(shí)間使6個(gè)開(kāi)關(guān)器件導(dǎo)通、關(guān)斷就可以得到3相交流輸出。以電壓型pwm逆變器為例示出開(kāi)關(guān)時(shí)間和電壓波形。、大功率并且為風(fēng)機(jī)/泵類(lèi)負(fù)載；
第二、裝置本身具有節(jié)電功能（軟件支持）；
第三、長(zhǎng)期連續(xù)運(yùn)行。
這是體現(xiàn)節(jié)電效果的三個(gè)條件。除此之外，無(wú)所謂節(jié)不節(jié)電，沒(méi)有什么意義。如果不加前提條件的說(shuō)變頻器工頻運(yùn)行節(jié)能，就是夸大或是商業(yè)炒作。知道了原委，你會(huì)巧妙的利用他為你服務(wù)。一定要注意使用場(chǎng)合和使用條件才好正確應(yīng)用，否則就是盲從、輕信而“受騙上當(dāng)”。世界籃球的格局本就是美國(guó)和歐洲占據(jù)著統(tǒng)治地位。而首屆男籃世界杯再次證明了這一點(diǎn)，美國(guó)一路兵不血刃，立陶宛作為傳統(tǒng)勁旅，殺入四強(qiáng)也是眾望所歸。塞爾維亞賽前并不被看好，但隨著特奧多西奇的強(qiáng)勢(shì)復(fù)蘇，他們有如今的成績(jī)，也就在情理之中了。
