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。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(gè)觸發(fā)電壓，小燈泡亮了，說明晶閘管導(dǎo)通了。這個(gè)演示實(shí)驗(yàn)給了我們什么啟發(fā)呢?這個(gè)實(shí)驗(yàn)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(gè)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)。晶閘管特點(diǎn)“一觸即發(fā)”。但是，如果陽極或控制極外加的是反向電壓。

通常，使用GTR做逆變管時(shí)的載波頻率底于2KHz。4.變頻器用GTR的選用⑴Uceo通常按電源線電壓U峰值的2倍來選擇。Uceo≥2廠2U在電源電壓為380V的變頻器中，應(yīng)有Uceo≥2廠2U*380V=1074.8V，故選用Uceo=1200V的GTR是適宜的。⑵Icm按額定電流In峰值的2倍來選擇Icm≥2廠2InGTR是用電流信號進(jìn)行驅(qū)動的，所需驅(qū)動功率較大，故基極驅(qū)動系統(tǒng)比較復(fù)雜，并使工作頻率難以提高，這是其不足之處。今天我告訴大家的是MOSFET以及IGBT功率場效應(yīng)晶體管（POWERMOSFET）它的3個(gè)極分別是源極S、漏極D和柵極G其工作特點(diǎn)是，G、S間的控制信號是電壓信號Ugs。
