Kubwera kwa ukadaulo wa Gallium Nitride (GaN) kwasintha kwambiri mawonekedwe a ma adapter amagetsi, zomwe zathandiza kupanga ma charger omwe ndi ang'onoang'ono kwambiri, opepuka, komanso ogwira ntchito bwino kuposa ma silicon omwe amagwiritsidwa ntchito kale. Pamene ukadaulo ukukulirakulira, tawona kubuka kwa mibadwo yosiyanasiyana ya ma semiconductor a GaN, makamaka GaN 2 ndi GaN 3. Ngakhale kuti onsewa amapereka kusintha kwakukulu kuposa silicon, kumvetsetsa kusiyana pakati pa mibadwo iwiriyi ndikofunikira kwa ogula omwe akufuna njira zotsogola komanso zogwira mtima zolipirira. Nkhaniyi ikufotokoza kusiyana kwakukulu pakati pa ma charger a GaN 2 ndi GaN 3, pofufuza kupita patsogolo ndi zabwino zomwe zimaperekedwa ndi kubwereza kwaposachedwa.
Kuti timvetse kusiyana kumeneku, ndikofunikira kumvetsetsa kuti "GaN 2" ndi "GaN 3" si mawu ofanana omwe amatanthauzidwa ndi bungwe limodzi lolamulira. M'malo mwake, akuyimira kupita patsogolo pakupanga ndi kupanga ma transistors amphamvu a GaN, omwe nthawi zambiri amagwirizanitsidwa ndi opanga enaake ndi ukadaulo wawo. Kawirikawiri, GaN 2 ikuyimira gawo loyambirira la ma charger a GaN omwe amagwira ntchito bwino pamalonda, pomwe GaN 3 ikuyimira zatsopano ndi kusintha kwaposachedwa.
Madera Ofunika Kwambiri Osiyanitsa:
Kusiyana kwakukulu pakati pa ma chaja a GaN 2 ndi GaN 3 nthawi zambiri kumakhala m'magawo otsatirawa:
1. Kusintha Mafupipafupi ndi Kuchita Bwino:
Chimodzi mwa ubwino waukulu wa GaN kuposa silicon ndi kuthekera kwake kusinthasintha pama frequency apamwamba kwambiri. Kusintha kwakukulu kumeneku kumalola kugwiritsa ntchito zigawo zazing'ono zoyendetsera (monga ma transformer ndi ma inductor) mkati mwa charger, zomwe zimathandiza kwambiri kuchepetsa kukula ndi kulemera kwake. Ukadaulo wa GaN 3 nthawi zambiri umakweza ma frequency osinthira awa kuposa GaN 2.
Kuwonjezeka kwa ma switching frequency mu mapangidwe a GaN 3 nthawi zambiri kumatanthauza kuti mphamvu yamagetsi yochokera pakhoma imayendetsedwa bwino kwambiri. Izi zikutanthauza kuti mphamvu yamagetsi yochuluka yomwe imatengedwa kuchokera pakhoma imaperekedwa ku chipangizo cholumikizidwa, ndipo mphamvu zochepa zimatayika ngati kutentha. Mphamvu yamagetsi yochuluka sikuti imangochepetsa kuwononga mphamvu komanso imathandizira kuti chojambulira chizigwira ntchito bwino, zomwe zingatalikitse nthawi yake yogwira ntchito ndikuwonjezera chitetezo.
2. Kusamalira Kutentha:
Ngakhale kuti GaN mwachibadwa imapanga kutentha kochepa kuposa silicon, kuyang'anira kutentha komwe kumapangidwa pamlingo wapamwamba wa mphamvu ndi ma frequency osinthira kumakhalabe gawo lofunika kwambiri pakupanga ma charger. Kupita patsogolo kwa GaN 3 nthawi zambiri kumaphatikizapo njira zabwino zowongolera kutentha pamlingo wa chip. Izi zitha kuphatikizapo mapangidwe abwino a chip, njira zotulutsira kutentha mkati mwa transistor ya GaN yokha, komanso njira zowunikira kutentha zomwe zingaphatikizidwe.
Kusamalira bwino kutentha kwa ma charger a GaN 3 kumawalola kuti azigwira ntchito moyenera pamagetsi amphamvu komanso katundu wokhazikika popanda kutenthedwa kwambiri. Izi ndizothandiza makamaka pazida zomwe zimafuna mphamvu zambiri monga ma laputopu ndi mapiritsi.
3. Kuphatikiza ndi Kuvuta:
Ukadaulo wa GaN 3 nthawi zambiri umakhala ndi kuphatikiza kwakukulu mkati mwa GaN power IC (Integrated Circuit). Izi zitha kuphatikizapo kuphatikiza ma circuitry ambiri owongolera, zinthu zoteteza (monga over-voltage, over-current, ndi over-temperature protection), komanso ngakhale ma gate driver omwe amalowa mwachindunji pa chip ya GaN.
Kuwonjezeka kwa kuphatikizana kwa mapangidwe a GaN 3 kungayambitse mapangidwe osavuta a charger okhala ndi zigawo zochepa zakunja. Izi sizimangochepetsa kuchuluka kwa zinthu komanso zimathandizanso kudalirika komanso kuthandizira kuti zikhale zochepa. Ma circuitry apamwamba kwambiri owongolera omwe amaphatikizidwa mu ma chip a GaN 3 angathandizenso kutumiza mphamvu molondola komanso moyenera ku chipangizo cholumikizidwa.
4. Kuchuluka kwa Mphamvu:
Kuchuluka kwa mphamvu, komwe kumayesedwa mu watts pa inchi imodzi ya cubic (W/in³), ndi njira yofunika kwambiri yowunikira kukhuthala kwa adaputala yamagetsi. Ukadaulo wa GaN, nthawi zambiri, umalola kuchuluka kwa mphamvu kwakukulu poyerekeza ndi silicon. Kupita patsogolo kwa GaN 3 nthawi zambiri kumakankhira ziwerengero za kuchuluka kwa mphamvuzi kwambiri.
Kuphatikiza kwa ma frequency apamwamba osinthira, magwiridwe antchito abwino, komanso kasamalidwe kabwino ka kutentha mu ma charger a GaN 3 kumathandiza opanga kupanga ma adapter ang'onoang'ono komanso amphamvu kwambiri poyerekeza ndi omwe amagwiritsa ntchito ukadaulo wa GaN 2 kuti apereke mphamvu yomweyo. Uwu ndi mwayi waukulu wosavuta kunyamula komanso kusavuta kugwiritsa ntchito.
5. Mtengo:
Monga momwe zilili ndi ukadaulo uliwonse womwe ukusintha, mibadwo yatsopano nthawi zambiri imabwera ndi mtengo wokwera woyambira. Zigawo za GaN 3, zomwe zimakhala zapamwamba kwambiri komanso zomwe zingagwiritse ntchito njira zovuta zopangira, zitha kukhala zodula kuposa zina za GaN 2. Komabe, pamene kupanga kukukulirakulira ndipo ukadaulo ukufalikira kwambiri, kusiyana kwa mtengo kukuyembekezeka kuchepa pakapita nthawi.
Kuzindikira Ma Charger a GaN 2 ndi GaN 3:
Ndikofunika kudziwa kuti opanga nthawi zambiri salemba mayina a ma charger awo kuti "GaN 2" kapena "GaN 3." Komabe, nthawi zambiri mutha kunena kuti ukadaulo wa GaN wapangidwa bwanji kutengera zomwe chajacho chimagwiritsa ntchito, kukula kwake, ndi tsiku lomwe chajacho chimatulutsa. Kawirikawiri, ma charger atsopano omwe ali ndi mphamvu zambiri komanso mawonekedwe apamwamba amatha kugwiritsa ntchito mibadwo ya GaN 3 kapena yamtsogolo.
Ubwino Wosankha GaN 3 Charger:
Ngakhale ma chaja a GaN 2 ali kale ndi ubwino waukulu kuposa silicon, kusankha chaja cha GaN 3 kungaperekenso zabwino zina, kuphatikizapo:
- Kapangidwe Kakang'ono Komanso Kopepuka: Sangalalani ndi kunyamulika bwino popanda kuwononga mphamvu.
- Kugwiritsa Ntchito Moyenera Kwambiri: Kuchepetsa kuwononga mphamvu komanso kuchepetsa mabilu amagetsi.
- Kugwira Ntchito Kwabwino kwa Kutentha: Khalani ndi ntchito yozizira, makamaka mukamagwira ntchito zochapira zambiri.
- Kuchaja Mofulumira Kwambiri (Mosalunjika): Kugwiritsa ntchito bwino kwambiri komanso kusamalira bwino kutentha kungathandize kuti chojambuliracho chizitha kugwira ntchito bwino kwa nthawi yayitali.
- Zinthu Zapamwamba Kwambiri: Gwiritsani ntchito njira zotetezera zophatikizika komanso kupereka mphamvu bwino.
Kusintha kuchokera ku GaN 2 kupita ku GaN 3 kukuyimira sitepe yofunika kwambiri pakusintha kwa ukadaulo wa adaputala yamagetsi ya GaN. Ngakhale mibadwo yonse iwiri imapereka kusintha kwakukulu poyerekeza ndi ma charger achikhalidwe a silicon, GaN 3 nthawi zambiri imapereka magwiridwe antchito abwino pankhani ya kusintha pafupipafupi, kugwira ntchito bwino, kuyang'anira kutentha, kuphatikiza, komanso pamapeto pake, kuchuluka kwa mphamvu. Pamene ukadaulo ukupitilira kukula ndikukhala wosavuta kupeza, ma charger a GaN 3 akukonzekera kukhala muyezo wofunikira kwambiri pakutumiza mphamvu zamagetsi zogwira ntchito bwino, zomwe zimapatsa ogula mwayi wolipiritsa bwino komanso wothandiza pazida zawo zosiyanasiyana zamagetsi. Kumvetsetsa kusiyana kumeneku kumapatsa mphamvu ogula kupanga zisankho zodziwikiratu posankha adaputala yawo yotsatira yamagetsi, kuonetsetsa kuti apindula ndi kupita patsogolo kwaposachedwa muukadaulo wolipiritsa.
