<p> 專業(yè)書籍中的開關(guān)電源是指利用現(xiàn)代電力技術(shù),控制開關(guān)晶體管開通和關(guān)斷的時(shí)間比率,維持穩(wěn)定輸出電壓的一種電源,開關(guān)電源一般由脈沖寬度調(diào)制（PWM）控制IC和MOSFET構(gòu)成。 </p> <p> 開關(guān)電源種類大體可以分為隔離和非隔離兩種,隔離型的必定有開關(guān)變壓器,而非隔離的未必一定有. </p> <p> 開關(guān)電源的工作原理是: </p> <p> 1.交流電源(如50HZ)輸入經(jīng)過整流濾波,成直流電源; </p> <p> 2.通過高頻PWM(脈沖寬度調(diào)制)信號控制開關(guān)管,將直流電源加到開關(guān)變壓器初級上; </p> <p> 3.開關(guān)變壓器次級感應(yīng)出高頻電壓,經(jīng)整流濾波供給負(fù)載; 上海高精度直流電源進(jìn)口開關(guān)可調(diào)直流電源。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

1、無線電手機(jī) 雷達(dá) </p> <p> 這類裝置的共同點(diǎn)是都帶有非常敏感的鑒頻或解調(diào)電路，不適合在高噪聲環(huán)境下工作。要想測試出這些產(chǎn)品的真實(shí)性能，就要確保直流電源不會(huì)給測試引入任何寄生噪聲。 </p> <p> <br /> </p> <p> 2、低功耗電子產(chǎn)品 </p> <p> 小功率(一般在200W以下)線性電源與開關(guān)電源價(jià)格差異小，且線性電源更具優(yōu)勢。 </p> <p> <br /> </p> <p> 3、系統(tǒng)要求通道數(shù)少 </p> <p> 針對此類應(yīng)用，主要是考慮性線電源的體積與重量因?yàn)閿?shù)量少而影響??；同時(shí)，通道數(shù)少，對于可編程電源 </p> <p> 串并機(jī)、主從控制，或者是全局控制無要求，線性電源可以滿足。 </p><p> （一）電源：用萬用表測一下主電路開關(guān)（接觸器）和控制保險(xiǎn)絲后面是否有電，這將排除這些元件斷路的可能性。 </p> <p> （二）整流器：整流器采用三相全控橋式整流電路，它包括六個(gè)快速熔斷器、六個(gè)晶閘管、六個(gè)脈沖變壓器和一個(gè)續(xù)流二極管。在快速熔斷器上有一個(gè)紅色的指示器，正常時(shí)指示器縮在外殼里邊，當(dāng)快熔燒斷后它將彈出，有些快熔的指示器較緊，當(dāng)快熔燒斷后，它會(huì)卡在里面，所以為可靠起見，可以用萬用表通斷檔測一下快熔，以判斷它是否燒斷。 </p> <p> 測量晶閘管的簡單方法是用萬用表電阻擋（200Ω擋）測一下其陰極—陽極、門極—陰極電阻，測量時(shí)晶閘管不用取下來。正常情況下，陽極—陰極間電阻應(yīng)為無窮大，門極—陰極電阻應(yīng)在10—50Ω之間，過大或過小都表明這只晶閘管門極失效，它將不能被觸發(fā)導(dǎo)通。 </p> <p> 脈沖變壓器次邊接在晶閘管上，原邊接在主控板上，用萬用表測量原邊電阻約為50Ω。續(xù)流二極管一般不容易出現(xiàn)故障，檢查時(shí)用萬用表二極管擋測其二端，正向時(shí)萬用表顯示結(jié)壓降約有500mV，反向不通。 </p> <p> （三）逆變器：逆變器包括四只快速晶閘管和四只脈沖變壓器，可以按上述方法檢查。 </p> <p> <br />

src="https://tyunfile.71360.com/UploadFile/szmdjd/637393089834770910/6557514.png"></div><p> 當(dāng)電源的內(nèi)電阻可以忽略不計(jì)時(shí)，可以認(rèn)為電源的電動(dòng)勢在量值上近似地等于電源兩極間的電位差或電壓。 </p> <p> 為了取得較高的直流電壓，常將直流電源串聯(lián)使用，這時(shí)總電動(dòng)勢為各電源的電動(dòng)勢之和，總內(nèi)阻也為各電源內(nèi)電阻之和。由于內(nèi)阻增大，一般只能用于所需電流強(qiáng)度較小的電路。為了取得較大的電流強(qiáng)度，可以將等電動(dòng)勢的直流電源并聯(lián)使用，這時(shí)總電動(dòng)勢即為單個(gè)電源的電動(dòng)勢，總內(nèi)阻為各電源內(nèi)電阻的并聯(lián)值。 </p> <p> 直流電源的類型直流電源的類型很多，不同類型的直流電源中，非靜電力的性質(zhì)不同，能量轉(zhuǎn)換的過程也不同。在化學(xué)電池(例如干電池、蓄電池等)中，非靜電力是與離子的溶解和沉積過程相聯(lián)系的化學(xué)作用，化學(xué)電池放電時(shí)，化學(xué)能轉(zhuǎn)化為電能和焦耳熱在溫差電源(例如金屬溫差電偶、半導(dǎo)體溫差電偶)中，非靜電力是與溫度差和電子的濃度差相聯(lián)系的擴(kuò)散作用，溫差電源向外電路提供功率時(shí)，熱能部分地轉(zhuǎn)化為電能。 </p> <p> 在直流發(fā)電機(jī)中,非靜電力是電磁感應(yīng)作用,直流發(fā)電機(jī)供電時(shí)，機(jī)械能轉(zhuǎn)化為電能與焦耳熱。在光電池中，非靜電力是光生伏打效應(yīng)的作用，光電池供電時(shí)，光能轉(zhuǎn)化為電能和焦耳熱。進(jìn)口可編程直流電源。山東安捷倫直流電源</p><p
