半導(dǎo)體激光器驅(qū)動模塊的作用

時間：2022-11-29作者：福建點碩自動化設(shè)備有限公司瀏覽：332

電機的驅(qū)動模塊通常有晶體管模塊、晶閘管（可控硅）模塊、IGBT模塊，當(dāng)然對于小型微特電機也用集成驅(qū)動模塊。

驅(qū)動電路的基本任務(wù)，就是將信息電子電路傳來的信號按照其控制目標(biāo)的要求，轉(zhuǎn)換為加在電力電子器件控制端和公共端之間，可以使其開通或關(guān)斷的信號。對半控型器件只需提供開通控制信號，對全控型器件則既要提供開通控制信號，又要提供關(guān)斷控制信號，以保器件按要求可靠導(dǎo)通或關(guān)斷。




擴展資料：


傳統(tǒng)的單元測試包括了驅(qū)動模塊（driver） 和樁模塊（stub）。驅(qū)動模塊的目的很單純，就是為了訪問類庫的屬性和方法，來檢測類庫的功能是否正確；

Normal 0 0 2 false false false EN-US KO X-NONE MicrosoftInternetExplorer4 如果被測試模塊中的函數(shù)是提供給其他函數(shù)調(diào)用的，在設(shè)計測試用例時就應(yīng)該設(shè)計驅(qū)動模塊（Driver）。

舉例來說：驅(qū)動模塊（Driver）可以通過模擬一系列用戶操作行為，比如選擇用戶界面上的某一個選項或者按下某個按鈕等，自動調(diào)用被測試模塊中的函數(shù)。驅(qū)動模塊（Driver）設(shè)置，使對模塊的測試不必與用戶界面真正交互。




描述




有些LED照明燈拆開后會看到一塊綠色或者偏黃色的PCB板，上面又很多元器件；而有些照明燈打開后就是鋁基板，而鋁基板上焊了很多的元器件。每個照明燈都會有電路板，只是電路板的形式不太一樣。LED照明燈是由很多個貼片發(fā)光二極管構(gòu)成的，根據(jù)不同的驅(qū)動方式，這些發(fā)光二極管或者串聯(lián)或者并聯(lián)，這些燈珠都是直流供電的，而市電是交流220V，如何才能使這些燈珠接入220V呢？這塊電路板的作用就是為燈珠提供驅(qū)動，使燈珠正常穩(wěn)定的工作。




發(fā)光二極管燈珠是電流型驅(qū)動的元器件，具有兩個重要的工作參數(shù)：電流和正向壓降。這類燈珠的壓降在（1-3）V左右，驅(qū)動電流大約幾十毫安。在驅(qū)動燈珠時即可以采用恒壓驅(qū)動又可以采用恒流驅(qū)動。照明行業(yè)多以恒流驅(qū)動為主，流過每一個燈珠的電流都是一樣的，可以保證發(fā)光比較均勻。而電路板的左右就是將220V交流電轉(zhuǎn)化為驅(qū)動燈珠的恒流電流。

有些元器件是直接焊接在鋁基板上的，這樣既可以節(jié)省空間，又能起到很好的散熱作用。鋁基板LED等如下圖所示。

不過大部分都是做成一個單獨的電路板用塑料外殼封裝成一個驅(qū)動模塊，這樣可以做到模塊化，如果驅(qū)動板壞了，再重新買一塊模塊就好，而不用整個把燈都換掉。LED驅(qū)動模塊如下圖所示。
