壓接式和焊接式可控硅模塊有哪些區(qū)別？可控硅模塊屬于一種使用模塊封裝形式，擁有三個PN結(jié)的四層結(jié)構(gòu)的大功率半導體器件，這種可控硅模塊的體積非常的小，結(jié)構(gòu)也十分的緊湊，對于維修與安裝都有很大的作用，可控硅模塊的類型非常的多，比方說壓接式可控硅模塊、焊接式可控硅模塊等，很多人不是很清楚兩者之間的差異，下面詳細的進行區(qū)分一下。①從電流方面來講，焊接式可控硅模塊可以做到160A電流，同時壓接式模塊的電流就能夠達到1200A，這就是講低于160A的模塊，不只是有焊接式的，同時也有壓接式的?？煽毓枘K②從外形方面來講，焊接式的可控硅模塊遠遠沒有壓接式的外形比較好，壓接式的屬于一體成型，技術(shù)十分的標準，焊接式的局部地區(qū)可能有焊接的痕跡，但是在使用的時候是沒有任何的影響的。③眾所周知，壓接式可控硅模塊的市場占有率是非常大的，有不少的公司都會使用壓接式可控硅模塊，這其中的原因可能使由于其外形十分的美觀，除此之外從價格方面來講，焊接式可控硅模塊的成本遠遠要比壓接式可控硅模塊的成本低。我公司的電力半導體器件有：全系列功率模塊(MTC，MFC，MDC，MDQ，MDS)，普通整流管(ZP)，快速整流管(ZK)。河北大功率晶閘管模塊正高電氣以快的速度提供好的產(chǎn)品質(zhì)量和好的價格及完善的售后服務(wù)。</p><div

它既保留了普通晶閘管耐壓高、電流大等優(yōu)點，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通之后即外于深度飽和狀態(tài)，而GTO在導通后只能達到臨界飽和，所以GTO門極上加負向觸發(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。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，*當黑表筆接G極。</p><p> 它可以用控制移相觸發(fā)脈沖來方便地改變負載的交流工作電壓，從而應(yīng)用于精確地調(diào)溫、調(diào)光等阻性負載及部分感性負載場合。⑵雙向可控硅輸出的普通型與單向可控硅反并聯(lián)輸出的增強型的區(qū)別在感性負載的場合，當LSR由通態(tài)關(guān)斷時，由于電流、電壓的相位不一致，將產(chǎn)生一個很大的電壓上升率dv/dt（換向dv/dt）加在雙向可控硅兩端，如此值超過雙向可控硅的換向dv/dt指標(典型值為10V/μs)則將導致延時關(guān)斷，甚至失敗。而單向可控硅為單極性工作狀態(tài)，只受靜態(tài)電壓上升率dv/dt(典型值為100V/μs)影響，由兩只單向可控硅反并聯(lián)構(gòu)成的增強型LSR比由一只雙向可控硅構(gòu)成的普通型LSR的換向dv/dt有了很大提高，因此在感性或容性負載場合宜選取增強型LSR。㈣繼電器負載輸出端電流等級及型號如下表：電流普通型2A普通型4A普通型8A普通型16A普通型25A普通型40A增強型15A增強型35A型號LSR-3Z02D3LSR-3Z02D2LSR-3Z02A3LSR-3P02D1-3Z04D3-3Z04D2-3Z04A3-3P04D1-3Z08D3-3Z08D2-3Z08A3-3P08D1-3Z16D3-3Z16D2-3Z16A3-3P16D1-3Z25D3-3Z25D2-3Z25A3-3P25D1-3Z40D3-3Z40D2-3Z40A3-3P40D1LSR-H3Z15D3LSR-H3Z15D2LSR-H3Z15A3LSR-H3P15D1-H3Z35D3-H3Z35D2-H3Z35A3-H3P35D1電流增強型50A增強型70A增強型90A。正高電氣企業(yè)價值觀：以人為本，顧客滿意，溝通合作，互惠互利。</p><div
