按現(xiàn)代電力電子的應(yīng)用領(lǐng)域,我們把電源模塊劃分如下:
綠色電源模塊
高速發(fā)展的計(jì)算機(jī)技術(shù)帶領(lǐng)人類進(jìn)入了信息社會(huì),同時(shí)也促進(jìn)了電源模塊技術(shù)的迅速發(fā)展。八十年代,計(jì)算機(jī)全面采用了開關(guān)電源,率先完成計(jì)算機(jī)電源換代。接著開關(guān)電源技術(shù)相繼進(jìn)入了電子、電器設(shè)備領(lǐng)域。
計(jì)算機(jī)技術(shù)的發(fā)展,提出綠色電腦和綠色電源模塊。綠色電腦泛指對環(huán)境無害的個(gè)人電腦和相關(guān)產(chǎn)品,綠色電源系指與綠色電腦相關(guān)的高效省電電源,根據(jù)美國環(huán)境保護(hù)署1992年6月17日“能源之星"計(jì)劃規(guī)定,桌上型個(gè)人電腦或相關(guān)的外圍設(shè)備,在睡眠狀態(tài)下的耗電量若小于30瓦,就符合綠色電腦的要求,提高電源效率是降低電源消耗的根本途徑。就目 前效率為75%的200瓦開關(guān)電源而言,電源自身要消耗50瓦的能源。
開關(guān)電源模塊
通信業(yè)的迅速發(fā)展極大的推動(dòng)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。
開關(guān)電源(4張)
因通信設(shè)備中所用集成電路的種類繁多,其電源電壓也各不相同,在通信供電系統(tǒng)中采用高功率密度的高頻DC-DC隔離電源模塊,從中間母線電壓(一般為48V直流)變換成所需的各種直流電壓,這樣可大大減小損耗、方便維護(hù),且安裝、增加非常方便。一般都可直接裝在標(biāo)準(zhǔn)控制板上,對二次電源的要求是高功率密度。因通信容量的不斷增加,通信電源容量也將不斷增加。
