SCR是主流的功率器件，IGBT模塊發(fā)展迅速，大有取代SCR的趨勢。SCR在大容量、低頻的電力電子裝置中仍占主導(dǎo)地位。性能優(yōu)良的晶閘管派生器件有很多，如快速、雙向、逆導(dǎo)、門極可關(guān)斷及光控等晶閘管。IGBT晶閘管，其結(jié)構(gòu)為絕緣柵雙極場效應(yīng)晶體管，可以觸發(fā)導(dǎo)通，淄博晶閘管驅(qū)動(dòng)模塊哪家好，也可以觸發(fā)管斷，所以稱為全控器件；IGBT晶閘管優(yōu)點(diǎn)：輸入阻抗高、開關(guān)速度快、安全工作區(qū)寬、飽和壓降低（甚至接近GTR的飽和壓降）、耐壓高、電流大。應(yīng)用于小體積變頻電源、電機(jī)調(diào)速、UPS以及逆變焊機(jī)當(dāng)中，淄博晶閘管驅(qū)動(dòng)模塊哪家好，是目前發(fā)展較為迅速的新一代功率器件。隨著封裝技術(shù)的發(fā)展，IGBT模塊已經(jīng)在很多運(yùn)用場合取代了SCR。晶閘管模塊和IGBT模塊工作原理對比兩者工作原理的不同就就是：晶閘管模塊是通過電流來控制，IGBT模塊是通過電壓變化來控制開關(guān)的。IGBT是可關(guān)斷的，晶閘管只能在電流過零時(shí)可關(guān)斷，工作頻率IGBT也比晶閘模塊高。IGBT是一種全控型電壓驅(qū)動(dòng)半導(dǎo)體開關(guān)，開通和關(guān)斷可控制；晶閘管需要電流脈沖驅(qū)動(dòng)開通，一旦開通，通過門極無法關(guān)斷，需要主電路電流關(guān)斷或很小才能關(guān)斷。晶閘管模塊像開關(guān)一樣通斷電流，像閘門一樣關(guān)停水流，它的作用就是一個(gè)字“閘”；所以晶閘管有兩個(gè)狀態(tài)，一個(gè)是導(dǎo)通狀態(tài)，一個(gè)是截至狀態(tài)，淄博晶閘管驅(qū)動(dòng)模塊哪家好。淄博正高電氣大力弘揚(yáng)開拓進(jìn)取,企業(yè)精神。淄博晶閘管驅(qū)動(dòng)模塊哪家好</p><div
