Kodi GaN ndi chiyani ndipo mukufunikira?

Gallium nitride, kapena GaN, ndi zinthu zomwe zayamba kugwiritsidwa ntchito ngati semiconductors mu charger. Amagwiritsidwa ntchito popanga ma LED kuyambira m'ma 90s, komanso ndi zida zodziwika bwino zama cell a solar pama satelayiti. Chinthu chachikulu chokhudza GaN pankhani ya ma charger ndikuti imatulutsa kutentha pang'ono. Kutentha kochepa kumatanthawuza kuti zigawozo zikhoza kukhala zoyandikana kwambiri, kotero kuti chojambulira chikhoza kukhala chaching'ono kuposa kale lonse-pokhala ndi mphamvu zonse ndi chitetezo.

Kodi charger ndi chiyani kwenikweni?

Ndife okondwa kuti mwafunsa.

Tisanayang'ane GaN mkati mwa charger, tiyeni tiwone zomwe charger imachita. Mafoni athu onse, mapiritsi, ndi laputopu ali ndi batire. Batire ikasamutsa mphamvu ku zida zathu, zomwe zikuchitika ndizomwe zimachitika ndi mankhwala. Chaja imatenga mphamvu yamagetsi kuti isinthe kusintha kwa mankhwalawo. M'masiku oyambilira, ma charger amangotumiza madzi ku batri mosalekeza, zomwe zingayambitse kuchulukira komanso kuwonongeka. Ma charger amakono amaphatikiza machitidwe owunikira omwe amachepetsa mphamvu yapano pomwe batire ikudzaza, zomwe zimachepetsa mwayi wowonjezera.

GaN ilowa m'malo mwa silicon

Kuyambira m'zaka za m'ma 80s, silicon yakhala yopangira ma transistors. Silikoni imayendetsa magetsi bwino kuposa zida zomwe zidagwiritsidwa ntchito kale - monga machubu otsekera - ndikuchepetsa mtengo, chifukwa sizokwera mtengo kwambiri kupanga. Kwa zaka zambiri, kupita patsogolo kwaukadaulo kwadzetsa magwiridwe antchito apamwamba omwe tidazolowera masiku ano. Kupita patsogolo kungangopita patali, ndipo ma transistors a silicon angakhale pafupi ndi momwe angapezere. Makhalidwe a zinthu za silicon pawokha mpaka kutentha ndi kusamutsa magetsi kumatanthauza kuti zigawozo sizingachepe.

GaN ndi yosiyana. Ndi chinthu chonga ngati kristalo chomwe chimatha kuyendetsa ma voltages apamwamba kwambiri. Magetsi amatha kudutsa muzinthu zopangidwa kuchokera ku GaN mwachangu kuposa silicon, zomwe zimatsogolera kukonzanso mwachangu. GaN imagwira ntchito bwino, motero kutentha kumakhala kochepa.
