晶閘管的主要工作特性
為了能夠直觀地認(rèn)識晶閘管的工作特性,大家先看這塊示教板(圖3)。
晶閘管VS與小燈泡EL串聯(lián)起來,通過開關(guān)S接在直流電源上。
注意陽極A是接電源的正極,陰極K接電源的負(fù)極,控制極G通過按鈕開關(guān)SB接在1.5V直流電源的正極
(這里使用的是KP1型晶閘管,若采用KP5型,
應(yīng)接在3V直流電源的正極)。晶閘管與電源的這種連接方式叫做正向連接,也就是說,
給晶閘管陽極和控制極所加的都是正向電壓。
現(xiàn)在我們合上電源開關(guān)S,小燈泡不亮,說明晶閘管沒有導(dǎo)通;再按一下按鈕開關(guān)SB,
給控制極輸入一個觸發(fā)電壓,小燈泡亮了,說明晶閘管導(dǎo)通了。
這個演示實驗給了我們什么啟發(fā)呢? 可控硅
這個實驗告訴我們,要使晶閘管導(dǎo)通,一是在它的陽極A與陰極K之間外加正向電壓,
二是在它的控制極G與陰極K之間輸入一個正向觸發(fā)電壓。
晶閘管導(dǎo)通后,松開按鈕開關(guān),去掉觸發(fā)電壓,仍然維持導(dǎo)通狀態(tài)。5STP03A1800
