晶閘管就不能導(dǎo)通?？刂茦O的作用是通過(guò)外加正向觸發(fā)脈沖使晶閘管導(dǎo)通，卻不能使它關(guān)斷。那么，用什么才能使導(dǎo)通的晶閘管關(guān)斷呢?使導(dǎo)通的晶閘管關(guān)斷，可以斷開(kāi)陽(yáng)極電源（圖3中的開(kāi)關(guān)S）或使陽(yáng)極電流小于維持導(dǎo)通的值（稱為維持電流）。如果晶閘管陽(yáng)極和陰極之間外加的是交流電壓或脈動(dòng)直流電壓，那么，在電壓過(guò)零時(shí)，晶閘管會(huì)自行關(guān)斷。應(yīng)用類型圖4示出了雙向可控硅的特性曲線。由圖可見(jiàn)，雙向可控硅的特性曲線是由三兩個(gè)象限內(nèi)的曲線組合成的。象限的曲線說(shuō)明當(dāng)加到主電極上的電壓使Tc對(duì)T1的極性為正時(shí)，我們稱為正向電壓，并用符號(hào)U21表示。當(dāng)這個(gè)電壓逐漸到等于轉(zhuǎn)折電壓UBO時(shí)，圖3(b)左邊的可控硅就觸發(fā)導(dǎo)通，這時(shí)的通態(tài)電流為I21。
