無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)技術,源于無(wu)(wu)線(xian)電(dian)(dian)(dian)(dian)(dian)力輸(shu)送(song)(song)技術。無(wu)(wu)線(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian),又(you)稱(cheng)作(zuo)(zuo)感應充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)、非接(jie)觸式感應充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian),是(shi)(shi)利用近場感應,也就(jiu)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)感耦合(he)(he),由供電(dian)(dian)(dian)(dian)(dian)設備(充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi))將能(neng)量傳送(song)(song)至用電(dian)(dian)(dian)(dian)(dian)的裝置,該裝置使用接(jie)收到的能(neng)量對電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian),并同時供其本身運作(zuo)(zuo)之用。由于充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)與用電(dian)(dian)(dian)(dian)(dian)裝置之間(jian)以電(dian)(dian)(dian)(dian)(dian)感耦合(he)(he)傳送(song)(song)能(neng)量,兩者之間(jian)不用電(dian)(dian)(dian)(dian)(dian)線(xian)連接(jie),因(yin)此充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)及用電(dian)(dian)(dian)(dian)(dian)的裝置都可以做到無(wu)(wu)導電(dian)(dian)(dian)(dian)(dian)接(jie)點(dian)外露。
 
        3月6日(ri)消息,創(chuang)威PCB電(dian)(dian)路板分板機分享,無線(xian)充電(dian)(dian)技(ji)(ji)術是(shi)(shi)電(dian)(dian)子(zi)行(xing)業增長(chang)最快的(de)(de)(de)領域,得到了廣泛(fan)應用。消費者對電(dian)(dian)池供電(dian)(dian)便攜(xie)式電(dian)(dian)子(zi)設(she)備(bei)的(de)(de)(de)需求,以及極不方便的(de)(de)(de)不斷進(jin)行(xing)充電(dian)(dian)等因素促使(shi)該技(ji)(ji)術的(de)(de)(de)應用高速增長(chang)。具有無線(xian)充電(dian)(dian)功能(neng)的(de)(de)(de)便攜(xie)式設(she)備(bei)發展(zhan)非常迅猛,隨著這種趨勢的(de)(de)(de)繼續,無線(xian)充電(dian)(dian)將成為我們日(ri)常生(sheng)活的(de)(de)(de)一部(bu)分,是(shi)(shi)一種便攜(xie)式設(she)備(bei)使(shi)用習(xi)慣(guan)。
 
        考慮到開發標(biao)準(zhun)、小型化解(jie)決方案和(he)低成本(ben)等(deng)因素,磁(ci)(ci)感應(ying)(MI)和(he)磁(ci)(ci)共振(zhen)(MR)是(shi)(shi)消費類(lei)市場(chang)上的(de)(de)(de)兩(liang)種(zhong)主要(yao)無(wu)線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)傳(chuan)送技(ji)(ji)術。由于(yu)緊密的(de)(de)(de)磁(ci)(ci)耦合,MI目前(qian)具(ju)有較(jiao)高的(de)(de)(de)電(dian)(dian)(dian)力傳(chuan)送能力,易于(yu)設(she)計,轉(zhuan)換效率較(jiao)高,而MR更具(ju)空間(jian)自由度,每個發射臺支持多個接(jie)收(shou)器(qi)件,對(dui)近場(chang)金屬物體(ti)的(de)(de)(de)熱積累影響較(jiao)小。在(zai)MI領域主要(yao)有兩(liang)種(zhong)標(biao)準(zhun):無(wu)線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)聯(lian)盟(meng)(WPC)的(de)(de)(de)‘Qi’標(biao)準(zhun),以(yi)及充(chong)(chong)(chong)電(dian)(dian)(dian)事物聯(lian)盟(meng)(PMA)的(de)(de)(de)相(xiang)關標(biao)準(zhun)。對(dui)于(yu)目前(qian)基于(yu)MI的(de)(de)(de)便(bian)攜式(shi)設(she)備設(she)計人員(yuan),這帶(dai)來了能否確(que)保Qi和(he)PMA兩(liang)種(zhong)標(biao)準(zhun)兼(jian)容的(de)(de)(de)問(wen)題(ti)。MR標(biao)準(zhun)主要(yao)是(shi)(shi)由A4WP (無(wu)線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)聯(lian)盟(meng))控制(zhi)的(de)(de)(de)。Qi或者PMA標(biao)準(zhun)的(de)(de)(de)產品兼(jian)容性(xing)目前(qian)還(huan)在(zai)討論中,預計明(ming)年就會出(chu)現基于(yu)A4WP的(de)(de)(de)產品。本(ben)文介紹無(wu)線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)以(yi)及相(xiang)關的(de)(de)(de)MI和(he)MR技(ji)(ji)術。還(huan)會討論芯片(pian)制(zhi)造(zao)商怎樣(yang)實現當今的(de)(de)(de)MI無(wu)線(xian)(xian)充(chong)(chong)(chong)電(dian)(dian)(dian)接(jie)收(shou)器(qi)IC,幫助克服(fu)MI技(ji)(ji)術的(de)(de)(de)雙重標(biao)準(zhun)問(wen)題(ti)。
