隨(sui)著(zhu)電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子(zi)技術的高速(su)發(fa)展，電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備與(yu)人們的工作、生活的關(guan)(guan)系日益密切(qie)，而電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備都離不開(kai)可(ke)靠的電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)，進入80年代計(ji)算(suan)機(ji)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)全面實現(xian)了開(kai)關(guan)(guan)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)化，率先完(wan)成計(ji)算(suan)機(ji)的電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)換代，進入90年代開(kai)關(guan)(guan)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)相繼進入各(ge)種電(dian)(dian)(dian)(dian)(dian)子(zi)、電(dian)(dian)(dian)(dian)(dian)器設(she)(she)備領(ling)域，程(cheng)控交換機(ji)、通(tong)訊(xun)、電(dian)(dian)(dian)(dian)(dian)子(zi)檢測設(she)(she)備電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)、控制設(she)(she)備電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)等都已廣(guang)泛地使用(yong)了開(kai)關(guan)(guan)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)，更促進了開(kai)關(guan)(guan)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)技術的迅速(su)發(fa)展。
開(kai)(kai)關電(dian)(dian)(dian)源(yuan)(yuan)是利用現(xian)代電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)子(zi)技(ji)術，控制(zhi)開(kai)(kai)關管開(kai)(kai)通和關斷的(de)(de)時間比(bi)率(lv)，維(wei)持穩定輸出電(dian)(dian)(dian)壓的(de)(de)一種電(dian)(dian)(dian)源(yuan)(yuan)，開(kai)(kai)關電(dian)(dian)(dian)源(yuan)(yuan)一般由脈沖寬(kuan)度調制(zhi)控制(zhi)IC和MOSFET構(gou)成(cheng)。隨著電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)子(zi)技(ji)術的(de)(de)發(fa)展(zhan)和創新，使得(de)開(kai)(kai)關電(dian)(dian)(dian)源(yuan)(yuan)技(ji)術也在(zai)不斷地(di)創新。目前，開(kai)(kai)關電(dian)(dian)(dian)源(yuan)(yuan)以(yi)小型(xing)、輕量和高效率(lv)的(de)(de)特點(dian)被廣(guang)泛應用幾乎所有的(de)(de)電(dian)(dian)(dian)子(zi)設備，是當今電(dian)(dian)(dian)子(zi)信息產(chan)業飛(fei)速發(fa)展(zhan)不可缺少的(de)(de)一種電(dian)(dian)(dian)源(yuan)(yuan)方式。
根據中國(guo)電源(yuan)(yuan)(yuan)學(xue)會收集整理的(de)數據，2008年全(quan)國(guo)開關電源(yuan)(yuan)(yuan)(主要包含(han)消費類開關電源(yuan)(yuan)(yuan)、工(gong)業(ye)(ye)(ye)類開關電源(yuan)(yuan)(yuan)、通信電源(yuan)(yuan)(yuan)、PC電源(yuan)(yuan)(yuan)，下同)產(chan)值(zhi)達到855億元，2009年達931億元，增長8.8%;2010年達到1027億元，增長10.3%。即使在全(quan)球金融危機沖(chong)擊下的(de)2009年，全(quan)行(xing)業(ye)(ye)(ye)產(chan)值(zhi)仍然達到1061億元，保持5%以上(shang)的(de)增長率。2010年隨著國(guo)家一系列宏觀刺(ci)激政策的(de)落實及全(quan)球經濟趨于穩定(ding)之后(hou)，我(wo)國(guo)電子信息產(chan)業(ye)(ye)(ye)很(hen)快恢(hui)復了發展勢(shi)(shi)頭，中國(guo)電源(yuan)(yuan)(yuan)行(xing)業(ye)(ye)(ye)更是借勢(shi)(shi)而上(shang)，產(chan)值(zhi)規模達到1172億元，增速超過10%。
這種具(ju)有小型化(hua)、重量輕、功率密度/轉換效率高、輸入電(dian)(dian)(dian)壓范圍廣、熱消耗較少(shao)等(deng)眾多優點的(de)電(dian)(dian)(dian)源(yuan)，在(zai)近幾年發(fa)展迅速，在(zai)電(dian)(dian)(dian)子行業中發(fa)展迅速。開關電(dian)(dian)(dian)源(yuan)產(chan)(chan)(chan)品(pin)(pin)(pin)分為標(biao)(biao)準(zhun)化(hua)產(chan)(chan)(chan)品(pin)(pin)(pin)和(he)非(fei)標(biao)(biao)準(zhun)化(hua)產(chan)(chan)(chan)品(pin)(pin)(pin)，一般(ban)來說(shuo)，標(biao)(biao)準(zhun)化(hua)產(chan)(chan)(chan)品(pin)(pin)(pin)訂單批(pi)量較大，毛利較低(di)，競爭激烈，而非(fei)標(biao)(biao)準(zhun)化(hua)產(chan)(chan)(chan)品(pin)(pin)(pin)訂單批(pi)量較小，但毛利較高，競爭較小。標(biao)(biao)準(zhun)化(hua)產(chan)(chan)(chan)品(pin)(pin)(pin)主要(yao)應用于消費(fei)類電(dian)(dian)(dian)子產(chan)(chan)(chan)品(pin)(pin)(pin)中、PC電(dian)(dian)(dian)源(yuan)等(deng)領域(yu)(yu)，而非(fei)標(biao)(biao)準(zhun)的(de)定制產(chan)(chan)(chan)品(pin)(pin)(pin)應用與通信電(dian)(dian)(dian)源(yuan)、新能源(yuan)和(he)工業電(dian)(dian)(dian)源(yuan)等(deng)領域(yu)(yu)。
標(biao)準(zhun)化(hua)開關電(dian)源企業一般根據客(ke)(ke)戶的(de)訂(ding)(ding)單(dan)(dan)組織生產(chan)(chan)(chan)，企業一般不備有(you)存貨。按訂(ding)(ding)單(dan)(dan)制造(zao)是指(zhi)接到(dao)客(ke)(ke)戶定(ding)單(dan)(dan)后，在(zai)已有(you)產(chan)(chan)(chan)品方案(an)的(de)基礎上(shang)修改(gai)設計(ji)、制造(zao)和(he)裝配，或重新研發設計(ji)，最終向(xiang)客(ke)(ke)戶提供定(ding)制產(chan)(chan)(chan)品的(de)生產(chan)(chan)(chan)方式。企業在(zai)接到(dao)客(ke)(ke)戶訂(ding)(ding)單(dan)(dan)后，按照訂(ding)(ding)單(dan)(dan)的(de)具體要求(qiu)，設計(ji)能夠滿足客(ke)(ke)戶特殊(shu)要求(qiu)的(de)定(ding)制化(hua)產(chan)(chan)(chan)品，從(cong)供應商的(de)選擇、原材料的(de)要求(qiu)、設計(ji)過(guo)(guo)程(cheng)、制造(zao)過(guo)(guo)程(cheng)以及成(cheng)品交付等(deng)等(deng)都(dou)由客(ke)(ke)戶訂(ding)(ding)單(dan)(dan)決(jue)定(ding)。開關電(dian)源產(chan)(chan)(chan)品型號非常多，一般企業無法在(zai)每(mei)一個細分市場(chang)獲得優勢，除(chu)電(dian)源適配器和(he)手(shou)機充電(dian)器這種(zhong)標(biao)準(zhun)化(hua)產(chan)(chan)(chan)品競爭(zheng)激烈毛利較低(di)之外，各企業都(dou)有(you)其主攻的(de)細分市場(chang)，積極(ji)開拓新興領域，能夠獲得較好的(de)利潤率。
與大(da)規模(mo)定制(zhi)(zhi)不(bu)同，定制(zhi)(zhi)開(kai)關電源更多(duo)(duo)的(de)(de)是小批量(liang)定制(zhi)(zhi)，為(wei)了較(jiao)好的(de)(de)控制(zhi)(zhi)成本，從而迅速向(xiang)顧客(ke)提供低(di)成本、高質量(liang)的(de)(de)定制(zhi)(zhi)產(chan)品，對企(qi)業的(de)(de)研發、生產(chan)管理(li)和采購能力提出了較(jiao)高的(de)(de)要求(qiu)，因此企(qi)業必須具備敏捷的(de)(de)產(chan)品開(kai)發設計能力和原材(cai)料采購能力，專門(men)為(wei)一種(zhong)產(chan)品設計的(de)(de)傳統(tong)的(de)(de)剛性生產(chan)線(xian)也將被能滿足(zu)多(duo)(duo)樣化和個(ge)性化的(de)(de)制(zhi)(zhi)造要求(qiu)的(de)(de)柔性生產(chan)線(xian)替代。
由于(yu)開關(guan)電(dian)源(yuan)行(xing)(xing)(xing)業以(yi)(yi)定制為主，企(qi)業的銷(xiao)(xiao)售(shou)與訂單緊(jin)密(mi)結合，因此銷(xiao)(xiao)售(shou)行(xing)(xing)(xing)為多發(fa)(fa)生在產品(pin)制造(zao)之前。同時(shi)，研(yan)發(fa)(fa)標準(zhun)產品(pin)向市場(chang)及(ji)客(ke)戶推廣(guang)，積極拓(tuo)展電(dian)子行(xing)(xing)(xing)業客(ke)戶，展示(shi)公司(si)研(yan)發(fa)(fa)設計能(neng)力(li)(li)、生產規模和(he)質(zhi)量管(guan)理(li)能(neng)力(li)(li)成(cheng)為企(qi)業銷(xiao)(xiao)售(shou)的重要手段。當前，開關(guan)電(dian)源(yuan)行(xing)(xing)(xing)業拓(tuo)展銷(xiao)(xiao)售(shou)渠道的方式主要有參加行(xing)(xing)(xing)業展會、在專業平面(mian)媒體和(he)行(xing)(xing)(xing)業網站(zhan)推廣(guang)以(yi)(yi)及(ji)客(ke)戶相互推薦等(deng)，而(er)獲得優質(zhi)客(ke)戶資源(yuan)則是企(qi)業實力(li)(li)最(zui)直(zhi)接(jie)的體現。
