可控硅是P1N1P2N2四層三端結(jié)構(gòu)元件，共有三個PN結(jié)，分析原理時，可以把它看作由一個PNP管和一個NPN管所組成。當陽極A加上正向電壓時，BG1和BG2管均處于放大狀態(tài)。此時，如果從控制極G輸入一個正向觸發(fā)信號，BG2便有基流ib2流過，經(jīng)BG2放大，其集電極電流ic2=β2ib2。因為BG2的集電極直接與BG1的基極相連，所以ib1=ic2。此時，電流ic2再經(jīng)BG1放大，于是BG1的集電極電流ic1=β1ib1=β1β2ib2。這個電流又流回到BG2的基極，表成正反饋，使ib2不斷增大，如此正向饋循環(huán)的結(jié)果，兩個管子的電流劇增，可控硅使飽和導通。 </p> <p> 由于BG1和BG2所構(gòu)成的正反饋作用，所以一旦可控硅導通后，即使控制極G的電流消失了，可控硅仍然能夠維持導通狀態(tài)，由于觸發(fā)信號只起觸發(fā)作用，沒有關(guān)斷功能，所以這種可控硅是不可關(guān)斷的。 </p> <p> 由于可控硅只有導通和關(guān)斷兩種工作狀態(tài)，所以它具有開關(guān)特性，這種特性需要一定的條件才能轉(zhuǎn)化天津快恢復可控硅模塊價格淄博正高電氣有限公司敢于承擔、克難攻堅。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

用萬用表電阻R×1檔，用紅黑兩表筆分別測任意兩引腳正反向電阻，結(jié)果其中兩組讀數(shù)為無窮大。若一組為數(shù)十歐姆時，該組紅黑表筆所接的兩引腳為陽極A1和控制極G，另一空腳即為第二陽極A2。確定A、G極后，再仔細測量A1、G極間正反向電阻，讀數(shù)相對較小的那次測量的黑表筆所接的引腳為陽極A1，紅表筆所接引腳為控制極G。將黑表筆接已確定了的第二陽極A2，紅表筆接陽極A1，此時萬用表指針應(yīng)不發(fā)生偏轉(zhuǎn)，阻值為無窮大。再用短接線將A2、G極瞬間短接，給G極加上正向觸發(fā)電壓，A2、A1間阻值約為10歐姆左右。隨后斷開A2、G極短接線，萬用表讀數(shù)應(yīng)保持10歐姆左右。互換紅黑表筆接線，紅表筆接第二陽極A2，黑表筆接陽極A1。同樣萬用表指針應(yīng)不發(fā)生偏轉(zhuǎn)，阻值為無窮大。用短接線將A2、G極間再次瞬間短接，給G極加上負向的觸發(fā)電壓，A1、A2間阻值也是10歐姆左右。隨后斷開A2、G極間短接線，萬用表讀數(shù)應(yīng)不變，保持10歐姆左右。符合以上規(guī)律，說明被測雙向可控硅管未損壞且三個引腳極性判斷正確。 </p> <p> 檢測較大功率可控硅管是地，需要在萬用表黑筆中串接一節(jié)1.5V干電池，以提高觸發(fā)電壓。 </p><p> 可控硅鑒別三個極的方法很簡單，根據(jù)P-N結(jié)的原理，用萬用表測量一下三個極之間的電阻值就可以判斷出來。 </p> <p> 陽極與陰極之間的正向和反向電阻在幾百千歐以上，陽極和控制極之間的正向和反向電阻在幾百千歐以上（它們之間有兩個P-N結(jié)，而且方向相反，因此陽極和控制極正反向都不通）。 </p> <p> 控制極與陰極之間是一個P-N結(jié)，因此它的正向電阻大約在幾歐-幾百歐的范圍，反向電阻比正向電阻要大。可是控制極二極管特性是不太理想的，反向不是完全呈阻斷狀態(tài)的，可以有比較大的電流通過，因此，有時測得控制極反向電阻比較小，并不能說明控制極特性不好。另外，在測量控制極正反向電阻時，萬用表應(yīng)放在R*10或R*1擋，防止電壓過高控制極反向擊穿。 </p> <p> 若測得元件陰陽極正反向已短路，或陽極與控制極短路，或控制極與陰極反向短路，或控制極與陰極斷路，說明元件已損壞。淄博正高電氣有限公司產(chǎn)品適用范圍廣，產(chǎn)品規(guī)格齊全，歡迎咨詢。</p> <span style="display:none;"></span><div style="width:100%;text-align: center;"><img

<p> 可控硅模塊導通的條件是陽極承受正電壓，只有當正向觸發(fā)電壓時，可控硅才能導通。由門級施加的正向觸發(fā)脈沖的較小寬度應(yīng)使陽極電流達到維持直通狀態(tài)所需的較小的陽極電流，即高于電流IL。可控硅導通后的電壓降很小。 </p> <p> 接通可控硅模塊的條件是將流過可控硅模塊的電流減小到較小的值，即保持電流IH。有兩種方法： </p> <p> 1.將正極電壓降低至數(shù)值，或添加反向陽極電壓。 </p> <p> 2.增加負載電路中的電阻。 </p> <p> 以上是可控硅模塊的導通狀態(tài)，希望能幫助您淄博正高電氣有限公司擁有先進的產(chǎn)品生產(chǎn)設(shè)備，雄厚的技術(shù)力量。青?？煽毓枘K組件</p><p
