它既保留了普通晶閘管耐壓高、電流大等優(yōu)點(diǎn)，以具有自關(guān)斷能力，使用方便，是理想的高壓、大電流開關(guān)器件。GTO的容量及使用壽命均超過巨型晶體管（GTR），只是工作頻紡比GTR低。GTO已達(dá)到3000A、4500V的容量。大功率可關(guān)斷晶閘管已用于斬波調(diào)速、變頻調(diào)速、逆變電源等領(lǐng)域，顯示出強(qiáng)大的生命力?？申P(guān)斷晶閘管也屬于PNPN四層三端器件，其結(jié)構(gòu)及等效電路和普通晶閘管相同，因此圖1*繪出GTO典型產(chǎn)品的外形及符號。大功率GTO大都制成模塊形式。盡管GTO與SCR的觸發(fā)導(dǎo)通原理相同，但二者的關(guān)斷原理及關(guān)斷方式截然不同。這是由于普通晶閘管在導(dǎo)通之后即外于深度飽和狀態(tài)，而GTO在導(dǎo)通后只能達(dá)到臨界飽和，所以GTO門極上加負(fù)向觸發(fā)信號即可關(guān)斷。GTO的一個重要參數(shù)就是關(guān)斷增益，βoff，它等于陽極比較大可關(guān)斷電流IATM與門極比較大負(fù)向電流IGM之比，有公式βoff=IATM/IGMβoff一般為幾倍至幾十倍。βoff值愈大，說明門極電流對陽極電流的控制能力愈強(qiáng)。很顯然，βoff與昌盛的hFE參數(shù)頗有相似之處。下面分別介紹利用萬用表判定GTO電極、檢查GTO的觸發(fā)能力和關(guān)斷能力、估測關(guān)斷增益βoff的方法。1．判定GTO的電極將萬用表撥至R×1檔，測量任意兩腳間的電阻，*當(dāng)黑表筆接G極。正高電氣建立雙方共贏的伙伴關(guān)系是我們孜孜不斷的追求。</p><div

在晶閘管模塊T的工作過程中，晶閘管模塊的陽極A和陰極K與電源和負(fù)載相連，構(gòu)成晶閘管模塊的主電路。晶閘管模塊的柵極G和陰極K與控制可控硅的裝置相連，形成晶閘管模塊的控制電路。 </p> <p> 從晶閘管模塊的內(nèi)部分析工作過程： </p> <p> 晶閘管模塊是一種四層三端器件。它有J1、J2和J3的三個pn結(jié)圖。中間的NP可分為PNP型三極管和NPN型三極管兩部分。 </p> <p> 當(dāng)晶閘管模塊承載正向陽極電壓時，為了制造晶閘管模塊導(dǎo)體銅，承受反向電壓的pn結(jié)J2必須失去其阻擋作用。每個晶體管的集電極電流同時是另一個晶體管的基極電流。因此，當(dāng)有足夠的柵極電流Ig流入時，兩個復(fù)合晶體管電路會形成較強(qiáng)的正反饋，從而導(dǎo)致兩個晶體管飽和導(dǎo)通，晶體管飽和導(dǎo)通。廣西穩(wěn)壓模塊哪家好</p><p
