原標題:IGBT功率(lv)模(mo)(mo)(mo)(mo)塊(kuai)如何(he)選(xuan)擇(ze)?在(zai)說(shuo)IGBT模(mo)(mo)(mo)(mo)塊(kuai)該(gai)如何(he)選(xuan)擇(ze)之前(qian),小(xiao)編先帶著大家了解下(xia)什么是IGBT?IGBT全稱為絕緣柵(zha)(zha)雙(shuang)極型晶(jing)體管(InsulatedGateBipolarTransistor),所以它是一個有MOSGate的(de)(de)(de)(de)(de)BJT晶(jing)體管,可以簡(jian)單理解為IGBT是MOSFET和BJT的(de)(de)(de)(de)(de)組合體。MOSFET主要是單一載(zai)(zai)流(liu)(liu)子(zi)(zi)(多子(zi)(zi))導電(dian)(dian),而BJT是兩種載(zai)(zai)流(liu)(liu)子(zi)(zi)導電(dian)(dian),所以BJT的(de)(de)(de)(de)(de)驅動電(dian)(dian)流(liu)(liu)會比MOSFET大,但是MOSFET的(de)(de)(de)(de)(de)控(kong)(kong)制級柵(zha)(zha)極是靠場效應(ying)反型來(lai)控(kong)(kong)制的(de)(de)(de)(de)(de),沒有額外的(de)(de)(de)(de)(de)控(kong)(kong)制端功率(lv)損耗(hao)。所以IGBT就是利用(yong)(yong)了MOSFET和BJT的(de)(de)(de)(de)(de)優(you)點(dian)組合起(qi)來(lai)的(de)(de)(de)(de)(de),兼有MOSFET的(de)(de)(de)(de)(de)柵(zha)(zha)極電(dian)(dian)壓控(kong)(kong)制晶(jing)體管(高輸(shu)入阻抗(kang)),又(you)利用(yong)(yong)了BJT的(de)(de)(de)(de)(de)雙(shuang)載(zai)(zai)流(liu)(liu)子(zi)(zi)達(da)到(dao)大電(dian)(dian)流(liu)(liu)(低導通(tong)壓降(jiang))的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)(Voltage-ControlledBipolarDevice)。從而達(da)到(dao)驅動功率(lv)小(xiao)、飽和壓降(jiang)低的(de)(de)(de)(de)(de)完美要求(qiu),廣泛應(ying)用(yong)(yong)于600V以上的(de)(de)(de)(de)(de)變流(liu)(liu)系統如交流(liu)(liu)電(dian)(dian)機(ji)、變頻器、開關(guan)電(dian)(dian)源、照(zhao)明電(dian)(dian)路、牽(qian)引(yin)(yin)傳(chuan)動等領域。1.在(zai)選(xuan)擇(ze)IGBT前(qian)需要確定(ding)主電(dian)(dian)路拓(tuo)撲結(jie)構,這個和IGBT選(xuan)型密切相(xiang)關(guan)。2.選(xuan)擇(ze)IGBT需要考慮的(de)(de)(de)(de)(de)參數如下(xia):額定(ding)工(gong)作電(dian)(dian)流(liu)(liu)、過載(zai)(zai)系數、散熱條件決定(ding)了IGBT模(mo)(mo)(mo)(mo)塊(kuai)的(de)(de)(de)(de)(de)額定(ding)電(dian)(dian)流(liu)(liu)參數,額定(ding)工(gong)作電(dian)(dian)壓、電(dian)(dian)壓波動、最大工(gong)作電(dian)(dian)壓決定(ding)了IGBT模(mo)(mo)(mo)(mo)塊(kuai)的(de)(de)(de)(de)(de)額定(ding)電(dian)(dian)壓參數,引(yin)(yin)線方(fang)式、結(jie)構也會給IGBT選(xuan)型提出要求(qiu)。,目前(qian)市(shi)(shi)面(mian)上的(de)(de)(de)(de)(de)叫主流(liu)(liu)的(de)(de)(de)(de)(de)IGBT產品都是進口的(de)(de)(de)(de)(de)。天津貿(mao)易模(mo)(mo)(mo)(mo)塊(kuai)報價表從應(ying)用(yong)(yong)領域規模(mo)(mo)(mo)(mo)占(zhan)比來(lai)看,中(zhong)國IGBT市(shi)(shi)場應(ying)用(yong)(yong)以新能源汽車、工(gong)業控(kong)(kong)制及消費(fei)電(dian)(dian)子(zi)(zi)為主,占(zhan)比分(fen)別是30%。
