氮化(hua)鎵GaN在(zai)數據中(zhong)心的(de)應(ying)用，能夠在(zai)節能、系統(tong)升級等方面(mian)帶來(lai)巨大的(de)優勢。

節能：數(shu)據(ju)(ju)中心(xin)電源的(de)(de)工作功率通常在3kW-6kW，主(zhu)流的(de)(de)650V GaN器(qi)件很(hen)適用。現有的(de)(de)數(shu)據(ju)(ju)中心(xin)電源整(zheng)體功率轉換能效(xiao)大約為75%，而采用GaN器(qi)件可以將能效(xiao)提升到87.5%。據(ju)(ju)測算，以每組10個(ge)機架的(de)(de)數(shu)據(ju)(ju)中心(xin)為例，基(ji)于(yu)GaN的(de)(de)PSU每年可以減少300萬美元的(de)(de)電費和超過100公噸(dun)的(de)(de)CO2排放量。

匹配PSU更換需求：GaN技術可以很(hen)好地匹配數據中心PSU電源架(jia)構的(de)(de)(de)更替潮(chao)流。一(yi)方面，PSU輸出(chu)電壓(ya)將從12V增加至48V，這(zhe)意(yi)味著(zhu)配電損耗可減(jian)少90%，為此高(gao)能效的(de)(de)(de)100V的(de)(de)(de)GaN器件(jian)預計將得到(dao)越(yue)(yue)來越(yue)(yue)多采用；另(ling)一(yi)方面，PSU制造商的(de)(de)(de)目標將電源功率從3kW提(ti)高(gao)到(dao)6kW，并且要(yao)將功率密度從45 W/in3升(sheng)級到(dao)100 W/in3，而這(zhe)只有GaN等寬禁帶半導體(ti)器件(jian)可以實(shi)現。

無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)技術(shu)有(you)兩(liang)種:電(dian)(dian)(dian)磁感應和(he)耦合共振(zhen)。GaN技術(shu)使更強大(da)、更高效的(de)(de)(de)無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)得以實(shi)現，從而釋放無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)技術(shu)的(de)(de)(de)真(zhen)正潛(qian)力(li)，讓(rang)用戶(hu)最終擺脫電(dian)(dian)(dian)線(xian)。無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)中的(de)(de)(de)輸(shu)入整流(liu)電(dian)(dian)(dian)路（AC/DC）、高頻逆(ni)變(bian)電(dian)(dian)(dian)路（DC/AC）、高頻整流(liu)電(dian)(dian)(dian)路以及恒(heng)壓和(he)恒(heng)流(liu)轉換電(dian)(dian)(dian)路（DC/DC）等電(dian)(dian)(dian)路中的(de)(de)(de)核心元件(jian)為功率半(ban)導體器(qi)件(jian)，相比于(yu)傳(chuan)統(tong)(tong)的(de)(de)(de)Si功率器(qi)件(jian)，GaN器(qi)件(jian)具有(you)寄生電(dian)(dian)(dian)容更小(xiao)、開(kai)關速(su)度快、工作頻率高和(he)開(kai)關損耗小(xiao)等特性(xing)(xing)，基于(yu)GaN器(qi)件(jian)的(de)(de)(de)無(wu)(wu)線(xian)電(dian)(dian)(dian)能傳(chuan)輸(shu)系(xi)(xi)統(tong)(tong)，可(ke)以顯著提升系(xi)(xi)統(tong)(tong)的(de)(de)(de)性(xing)(xing)能指標，對(dui)無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)的(de)(de)(de)開(kai)發和(he)推廣有(you)重要(yao)意義。據研究，GaN器(qi)件(jian)系(xi)(xi)統(tong)(tong)的(de)(de)(de)無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)距離超(chao)過(guo)40mm，約為傳(chuan)統(tong)(tong)技術(shu)的(de)(de)(de)8倍，而且功率可(ke)以超(chao)過(guo)500W，效率可(ke)以達(da)到95%。
