GaN yog dab tsi thiab vim li cas koj xav tau nws?

Gallium nitride, lossis GaN, yog cov khoom siv uas tau pib siv rau cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob. Nws tau siv los ua LEDs pib hauv 90s, thiab nws tseem yog cov khoom siv nrov rau hnub ci cell arrays ntawm satellites. Qhov tseem ceeb ntawm GaN thaum nws los txog rau lub chargers yog tias nws ua kom sov tsawg. Tsawg cua sov txhais tau hais tias cov khoom tuaj yeem nyob ze ua ke, yog li lub charger tuaj yeem ua me dua li yav dhau los-thaum tswj hwm txhua lub zog muaj peev xwm thiab cov qauv kev nyab xeeb.

Lub charger tiag tiag yog dab tsi?

Peb zoo siab koj nug.

Ua ntej peb saib GaN ntawm sab hauv ntawm lub charger, cia peb saib seb lub charger ua li cas. Txhua ntawm peb cov smartphones, ntsiav tshuaj, thiab laptops muaj roj teeb. Thaum lub roj teeb hloov hluav taws xob rau peb cov khoom siv, qhov tshwm sim tiag tiag yog cov tshuaj tiv thaiv tshuaj. Lub charger siv hluav taws xob tam sim no rov qab cov tshuaj tiv thaiv tshuaj. Thaum ntxov, chargers cia li xa kua txiv mus rau lub roj teeb tas li, uas tuaj yeem ua rau overcharging thiab puas. Cov khoom siv niaj hnub no suav nrog kev saib xyuas cov tshuab uas txo qis tam sim no raws li lub roj teeb puv, uas txo qis qhov muaj peev xwm ntawm overcharging.

Thaum tshav kub kub yog nyob rau:
GaN hloov silicon

Txij li thaum xyoo 80s, silicon yog cov khoom siv rau transistors. Silicon ua hluav taws xob zoo dua li cov khoom siv yav dhau los - xws li lub tshuab nqus tsev - thiab ua rau cov nqi qis, vim nws tsis kim dhau los tsim. Tau ntau xyoo lawm, kev txhim kho thev naus laus zis tau ua rau muaj kev ua haujlwm siab uas peb tau ua rau niaj hnub no. Kev nce qib tuaj yeem mus kom deb li deb tau, thiab silicon transistors yuav nyob ze rau qhov zoo li lawv yuav tau txais. Cov khoom ntawm cov khoom siv silicon nws tus kheej kom deb li deb ntawm qhov kub thiab hluav taws xob hloov pauv txhais tau tias cov khoom tsis tuaj yeem tau txais me dua.

GaN txawv. Nws yog cov khoom siv zoo li siv lead ua uas muaj peev xwm ua kom muaj hluav taws xob ntau dua. Cov hluav taws xob tam sim no tuaj yeem dhau los ntawm cov khoom tsim los ntawm GaN sai dua silicon, uas ua rau kev ua haujlwm sai dua. GaN ua haujlwm tau zoo dua, yog li muaj cua sov tsawg dua.
