開關(guān)變壓器起到功率傳遞、電壓/電流變換的作用。開關(guān)變壓器為降壓變壓器。開關(guān)電源的特點如下:1)開關(guān)電源的振蕩和調(diào)壓方式是利用改變脈沖寬度或周期來調(diào)整輸出電壓的,稱為時間比例控制,又分為PWM(調(diào)寬)和PFM(調(diào)頻)兩種控制方式。2)從電路的能量轉(zhuǎn)換特性看,可分為正激和反激兩種工作方式。開關(guān)管飽和導(dǎo)通時,二次繞組連接的整流器受反偏壓而截止,開關(guān)變壓器的一次繞組流入電流而儲能〈電磁轉(zhuǎn)換)。開關(guān)管截止時,二次繞組經(jīng)負(fù)載電路釋放電能(磁電轉(zhuǎn)換)。正激方式則與此相反,實際應(yīng)用不多。3)從開關(guān)變壓器的一次電路結(jié)構(gòu)來看,有分立元件構(gòu)成的和集成振蕩芯片構(gòu)成的兩種電路形式。因而從振蕩信號的來源看,又分為自激(分立零件)和他激式(IC電路)開關(guān)電源。

在應(yīng)用可控硅時,只要在控制極加上很小的電流或電壓,就能控制很大的陽極電流或電壓。電流容量達(dá)幾百安培以至上千安培的可控硅元件。一般把5安培以下的可控硅叫小功率可控硅,50安培以上的可控硅叫大功率可控硅。電壓測方法可控硅為什么其有“以小控大”的可控性呢?下面我們用圖表-27來簡單分析可控硅的工作原理。首先,可以把從陰極向上數(shù)的、三層看面是一只NPN型號晶體管,而三四層組成另一只PNP型晶體管。其中第第三層為兩管交迭共用。當(dāng)在陽極和陰極之間加上一個正向電壓Ea,又在控制極G和陰極C之間(相當(dāng)BG1的基一射間)輸入一個正的觸發(fā)信號,BG1將產(chǎn)生基極電流Ib1,經(jīng)放大,BG1將有一個放大了β1倍的集電極電流IC1。

智能軟啟動器利用三對晶閘管的電子開關(guān)特性,通過啟動器中的微處理器,控制其觸發(fā)脈沖的遲早來改變觸發(fā)延遲角的大小,而晶閘管觸發(fā)延遲角的大小,又可改變晶閘管的導(dǎo)通時間,從而終改變加到定子繞組的三相電壓的大小。異步電動機(jī)定子調(diào)壓的特點是,電動機(jī)轉(zhuǎn)矩近似與定子電壓的二次方成正比,電動機(jī)的電流和定子電壓成正比,因此,電動機(jī)的啟動轉(zhuǎn)矩和初始電流的限制可以通過定子電壓的控制來實現(xiàn)。而電動機(jī)定子電壓又是通過晶閘管的導(dǎo)通角來控制的,所以不同的初始相角可實現(xiàn)不同的端電壓,以滿足不同的負(fù)載啟動特性。在電動機(jī)啟動過程中,晶閘管的導(dǎo)通角逐漸增大,晶閘管的輸出電壓也逐漸增加,電動機(jī)從零開始加速,直到晶閘管全導(dǎo)通,啟動完成,從而實現(xiàn)電動機(jī)的無級平滑啟動。
