DSQC563
DSQC563邏輯設(shè)計(jì)法是利用邏輯代數(shù)來進(jìn)行電路設(shè)計(jì),從生產(chǎn)機(jī)械的拖動(dòng)要求和工藝要求出發(fā),將控制電路中的接觸器、繼電器線圈的通電與斷電,觸點(diǎn)的閉合與斷開,主令電器的接通與斷開看成邏輯變量,根據(jù)控制要求將它們之間的關(guān)系用邏輯關(guān)系式來表達(dá),然后再化簡(jiǎn),做出相應(yīng)的電路圖
邏輯設(shè)計(jì)法的優(yōu)點(diǎn)是能獲得理想、經(jīng)濟(jì)的方案,但這種方法設(shè)計(jì)難度較大,整個(gè)設(shè)計(jì)過程較復(fù)雜,還要涉及一些新概念,因此,在一般常規(guī)設(shè)計(jì)中,很少單獨(dú)采用。其具體設(shè)計(jì)過程可參閱專門論述資料,這里不再作進(jìn)一步介紹
主電路是給異步電動(dòng)機(jī)提供調(diào)壓調(diào)頻電源的電力變換部分,變頻器的主電路大體上可分為兩類:電壓型是將電壓源的直流變換為交流的變頻器,直流回路的濾波是電容。電流型是將電流源的直流變換為交流的變頻器,其直流回路濾波是電感。 它由三部分構(gòu)成,將工頻電源變換為直流功率的“整流器”,吸收在變流器和逆變器產(chǎn)生的電壓脈動(dòng)的“平波回路”,以及將直流功率變換為交流功率的“逆變器”
