  人(ren)們在開關(guan)電源技術(shu)領域(yu)是(shi)邊(bian)開(kai)(kai)發相(xiang)關(guan)(guan)電力電子器(qi)件,邊(bian)開(kai)(kai)發開(kai)(kai)關(guan)(guan)變頻技術(shu),兩者相(xiang)互(hu)促進推動著(zhu)開(kai)(kai)關(guan)(guan)電源每年以(yi)超過(guo)兩位數(shu)字的(de)增長率向著(zhu)輕、小、薄(bo)、低噪聲、高可靠(kao)、抗干擾的(de)方向發展。開(kai)(kai)關(guan)(guan)電源可分為AC/DC和DC/DC兩大(da)類。

微型(xing)低功率開關電源
  開關(guan)(guan)電(dian)源(yuan)(yuan)正在(zai)(zai)走(zou)向大眾化(hua),微(wei)型化(hua)。開關(guan)(guan)電(dian)源(yuan)(yuan)將(jiang)逐步取代變壓器(qi)在(zai)(zai)生(sheng)活中的所有應(ying)用(yong),低功率(lv)微(wei)型開關(guan)(guan)電(dian)源(yuan)(yuan)的應(ying)用(yong)要(yao)首先體現(xian)(xian)在(zai)(zai),數(shu)顯(xian)表(biao)、智能(neng)(neng)電(dian)表(biao)、手機充電(dian)器(qi)等(deng)方面(mian)。現(xian)(xian)階段國家在(zai)(zai)大力推廣智能(neng)(neng)電(dian)網建設,對電(dian)能(neng)(neng)表(biao)的要(yao)求大幅提高(gao),開關(guan)(guan)電(dian)源(yuan)(yuan)將(jiang)逐步取代變壓器(qi)在(zai)(zai)電(dian)能(neng)(neng)表(biao)上面(mian)的應(ying)用(yong)。
反轉式串聯(lian)開關電源
  反轉式(shi)串(chuan)(chuan)聯(lian)(lian)(lian)開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)(dian)源(yuan)(yuan)與(yu)一般(ban)串(chuan)(chuan)聯(lian)(lian)(lian)式(shi)開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)(dian)源(yuan)(yuan)的區(qu)別是,這種(zhong)反轉式(shi)串(chuan)(chuan)聯(lian)(lian)(lian)開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)(dian)源(yuan)(yuan)輸出(chu)(chu)的電(dian)(dian)(dian)壓(ya)是負電(dian)(dian)(dian)壓(ya),正(zheng)好(hao)與(yu)一般(ban)串(chuan)(chuan)聯(lian)(lian)(lian)式(shi)開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)(dian)源(yuan)(yuan)輸出(chu)(chu)的正(zheng)電(dian)(dian)(dian)壓(ya)極性(xing)相(xiang)反;并(bing)且由于儲能電(dian)(dian)(dian)感L只(zhi)在開(kai)(kai)(kai)關(guan)(guan)K關(guan)(guan)斷時才向負載輸出(chu)(chu)電(dian)(dian)(dian)流,因(yin)此,在相(xiang)同條件下,反轉式(shi)串(chuan)(chuan)聯(lian)(lian)(lian)開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)(dian)源(yuan)(yuan)輸出(chu)(chu)的電(dian)(dian)(dian)流比串(chuan)(chuan)聯(lian)(lian)(lian)式(shi)開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)(dian)源(yuan)(yuan)輸出(chu)(chu)的電(dian)(dian)(dian)流小(xiao)一倍。
