GaN ni iki kandi kuki ubikeneye?

Nitride ya Gallium, cyangwa GaN, ni ibikoresho bitangiye gukoreshwa kuri semiconductor muri charger. Byakoreshejwe mu gukora LED guhera mu myaka ya za 90, kandi ni ibikoresho bizwi cyane ku mirasire y'izuba kuri satelite. Ikintu cyingenzi kuri GaN kubijyanye na charger nuko itanga ubushyuhe buke. Ubushyuhe buke bivuze ko ibice bishobora kuba hafi, bityo charger irashobora kuba nto kuruta mbere hose - mugihe ikomeza imbaraga zose nubuziranenge bwumutekano.

Amashanyarazi akora iki?

Twishimiye ko wabajije.

Mbere yuko tureba GaN imbere yumuriro, reka turebe icyo charger ikora. Buri terefone yacu, tableti, na mudasobwa zigendanwa bifite bateri. Iyo bateri yohereza ingufu mubikoresho byacu, ibibera mubyukuri reaction ya chimique. Amashanyarazi afata amashanyarazi kugirango ahindure iyo miti. Mu minsi ya mbere, charger zohereje umutobe muri bateri buri gihe, ibyo bikaba byaviramo kwishyurwa birenze no kwangirika. Amashanyarazi agezweho arimo sisitemu yo kugenzura igabanya ikigezweho nkuko bateri yuzura, bigabanya amahirwe yo kwishyurwa birenze.

Ubushyuhe buri:
GaN isimbuye silicon

Kuva mu myaka ya za 80, silicon niyo yagiye mu bikoresho bya tristoriste. Silicon itwara amashanyarazi neza kuruta ibikoresho byakoreshwaga mbere - nk'imiyoboro ya vacuum - kandi ikagabanya ibiciro, kuko kubyara umusaruro bihenze cyane. Mu myaka mirongo, iterambere ryikoranabuhanga ryagejeje kumikorere yo hejuru tumenyereye uyumunsi. Iterambere rishobora kugera kure gusa, kandi transistor ya silicon irashobora kuba hafi nkibyiza bagiye kubona. Imiterere yibikoresho bya silicon ubwayo nkubushyuhe no guhererekanya amashanyarazi bivuze ko ibice bidashobora kubona bito.

GaN iratandukanye. Nibintu bisa na kristu ishoboye gutwara voltage ndende cyane. Umuyagankuba urashobora kunyura mubice bikozwe muri GaN byihuse kuruta silikoni, biganisha no gutunganya byihuse. GaN ikora neza, nuko ubushyuhe buke.
