style="text-indent:25px">對于系統(tǒng)設(shè)計工程師來說，選擇電源模塊而非從元件層面來設(shè)計電源轉(zhuǎn)換器有許多原因，易用性和上市速度是其中相對主要的原因。通過只添加輸入和輸出電容，這些電源客戶能夠相對輕松和快速地完成其設(shè)計，并確信其基本性能和空間要求都已得到滿足。電源模塊是采用密閉封裝的完整電源轉(zhuǎn)換器系統(tǒng)，其中包括一個PWM控制器、同步開關(guān)MOSFET、電感和被動元件。系統(tǒng)設(shè)計工程師必須克服各種障礙，包括由于元件間極小間隙而引起的噪聲耦合可能性的增加，以及由于功率處理能力的繼續(xù)增加和更小占位面積而造成的散熱問題。</p><p style="text-indent:25px">開關(guān)形式電源：簡稱SMPS，又稱交流式電源、開關(guān)變換器，是一種高頻化電能轉(zhuǎn)換安裝，是電源供給器的一種。其功用是將一個位準(zhǔn)的電壓，透過不同方式的架構(gòu)轉(zhuǎn)換為用戶端所需求的電壓或電流。開關(guān)電源的輸入多半是交流電源（例如市電）或是直流電源，而輸出多半是需求直流電源的設(shè)備，例如個人電腦，而開關(guān)電源就停止兩者之間電壓及電流的轉(zhuǎn)換。開關(guān)電源不同于線性電源，開關(guān)電源應(yīng)用的切換晶體管多半是在全開形式（飽和區(qū)）及全閉形式（截止區(qū)）之間切換，這兩個形式都有低耗散的特性，切換之間的轉(zhuǎn)換會有較高的耗散，但時間很短，因而比擬儉省能源，產(chǎn)生廢熱較少。理想上，開關(guān)電源自身是不會耗費(fèi)電能的。電壓穩(wěn)壓是透過調(diào)整晶體管導(dǎo)通及斷路的時間來到達(dá)。相反的，線性電源在產(chǎn)生輸出電壓的過程中，晶體管工作在放大區(qū)，自身也會耗費(fèi)電能。開關(guān)電源的高轉(zhuǎn)換效率是其一大優(yōu)點(diǎn)，而且由于開關(guān)電源工作頻率高，能夠運(yùn)用小尺寸、輕重量的變壓器，因而開關(guān)電源也會比線性電源的尺寸要小，重量也會比擬輕。電壓調(diào)整率(源效應(yīng))：衡量模塊在不同輸入電壓的情況下輸出電壓的變化情況。</p><div

style="text-indent:25px">通信業(yè)的迅速發(fā)展極大地推動了通信電源的發(fā)展。高頻小型化的開關(guān)電源及其技術(shù)已成為現(xiàn)代通信供電系統(tǒng)的主流。在通信領(lǐng)域中，通常將整流器稱為一次電源，而將直流-直流(DC-DC)變換器稱為二次電源。一次電源的作用是將單相或三相交流電網(wǎng)變換成標(biāo)稱值為48V的直流電源。當(dāng)前在程控交換機(jī)用的一次電源中，傳統(tǒng)的相控式穩(wěn)壓電源己被高頻開關(guān)電源取代，高頻開關(guān)電源(也稱為開關(guān)型整流器SMR)通過MOSFET或IGBT的高頻工作，開關(guān)頻率一般控制在50-100kHz范圍內(nèi)，實(shí)現(xiàn)高效率和小型化。近幾年，開關(guān)整流器的功率容量不斷擴(kuò)大，單機(jī)容量己從48V/12.5A、48V/20A擴(kuò)大到48V/200A、48V/400A。充電電源模塊具有模塊化設(shè)計、防潮、抗震動、一致性好、應(yīng)用簡單，可靠性高等優(yōu)點(diǎn)。河北充電電源采購哪家好</p><p
