氮化鎵GaN在數據中心的(de)應用，能(neng)夠在節能(neng)、系統升(sheng)級等方面帶(dai)來巨大的(de)優勢(shi)。

節(jie)能(neng)(neng)：數據中(zhong)心電源的(de)工(gong)作功率通(tong)常在3kW-6kW，主流的(de)650V GaN器(qi)件(jian)很適(shi)用(yong)。現有的(de)數據中(zhong)心電源整(zheng)體功率轉換能(neng)(neng)效(xiao)大約為75%，而采用(yong)GaN器(qi)件(jian)可以將能(neng)(neng)效(xiao)提升到(dao)87.5%。據測算，以每組10個機架的(de)數據中(zhong)心為例(li)，基于GaN的(de)PSU每年可以減少300萬美元(yuan)的(de)電費和超過100公噸的(de)CO2排放量(liang)。

匹配PSU更換(huan)需求：GaN技(ji)術可(ke)(ke)以很好(hao)地匹配數(shu)據中心PSU電(dian)源架構的更替潮流。一(yi)方面，PSU輸出電(dian)壓(ya)將從(cong)12V增(zeng)加至48V，這意味著配電(dian)損耗可(ke)(ke)減少90%，為(wei)此高能效的100V的GaN器件預計(ji)將得到越來越多(duo)采用；另(ling)一(yi)方面，PSU制造商(shang)的目(mu)標將電(dian)源功率從(cong)3kW提高到6kW，并(bing)且要將功率密度從(cong)45 W/in3升(sheng)級到100 W/in3，而這只有(you)GaN等寬禁帶(dai)半導體器件可(ke)(ke)以實(shi)現。

無線(xian)(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)技(ji)術(shu)(shu)(shu)有兩種:電(dian)(dian)(dian)(dian)(dian)磁感應和(he)(he)耦合(he)共(gong)振。GaN技(ji)術(shu)(shu)(shu)使更強(qiang)大、更高(gao)效(xiao)的(de)(de)無線(xian)(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)得以(yi)實(shi)現，從而釋放無線(xian)(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)技(ji)術(shu)(shu)(shu)的(de)(de)真正潛(qian)力，讓用戶最終擺(bai)脫電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)。無線(xian)(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)中的(de)(de)輸入整流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)路（AC/DC）、高(gao)頻逆(ni)變電(dian)(dian)(dian)(dian)(dian)路（DC/AC）、高(gao)頻整流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)路以(yi)及恒壓和(he)(he)恒流(liu)(liu)轉換(huan)電(dian)(dian)(dian)(dian)(dian)路（DC/DC）等電(dian)(dian)(dian)(dian)(dian)路中的(de)(de)核(he)心元件(jian)(jian)(jian)為功率(lv)(lv)半導體(ti)器(qi)件(jian)(jian)(jian)，相比于傳(chuan)統(tong)(tong)的(de)(de)Si功率(lv)(lv)器(qi)件(jian)(jian)(jian)，GaN器(qi)件(jian)(jian)(jian)具有寄(ji)生電(dian)(dian)(dian)(dian)(dian)容(rong)更小、開(kai)關速(su)度快、工作頻率(lv)(lv)高(gao)和(he)(he)開(kai)關損耗小等特性，基于GaN器(qi)件(jian)(jian)(jian)的(de)(de)無線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)能(neng)傳(chuan)輸系統(tong)(tong)，可以(yi)顯著提升系統(tong)(tong)的(de)(de)性能(neng)指標(biao)，對(dui)無線(xian)(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)的(de)(de)開(kai)發和(he)(he)推廣有重要意義。據研究，GaN器(qi)件(jian)(jian)(jian)系統(tong)(tong)的(de)(de)無線(xian)(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)距離(li)超(chao)過(guo)40mm，約為傳(chuan)統(tong)(tong)技(ji)術(shu)(shu)(shu)的(de)(de)8倍，而且功率(lv)(lv)可以(yi)超(chao)過(guo)500W，效(xiao)率(lv)(lv)可以(yi)達(da)到95%。
