Ukuvula Ukuvela: Ukuqonda Umehluko Phakathi Kwezishaja ze-GaN 2 ne-GaN 3

Ukufika kobuchwepheshe beGallium Nitride (GaN) kushintshe indlela ama-adapter kagesi asebenza ngayo, okwenza kube lula ukudalwa kwamashaja amancane kakhulu, alula, futhi asebenza kahle kakhulu kunalawo ajwayelekile asekelwe ku-silicon. Njengoba ubuchwepheshe bukhula, sibone ukuvela kwezizukulwane ezahlukene zama-semiconductors e-GaN, ikakhulukazi i-GaN 2 ne-GaN 3. Nakuba zombili zinikeza ukuthuthuka okukhulu kune-silicon, ukuqonda umehluko phakathi kwalezi zizukulwane ezimbili kubalulekile kubathengi abafuna izixazululo zokushaja ezithuthuke kakhulu nezisebenza kahle. Lesi sihloko sihlola umehluko obalulekile phakathi kwamashaja e-GaN 2 ne-GaN 3, sihlola intuthuko kanye nezinzuzo ezinikezwa yi-iteration yakamuva.

Ukuze siqonde umehluko, kubalulekile ukuqonda ukuthi i-"GaN 2" kanye ne-"GaN 3" akuwona amagama ajwayelekile achazwa indikimba eyodwa ebusayo. Esikhundleni salokho, amelela intuthuko ezinqubweni zokuklama nokukhiqiza ama-transistors kagesi e-GaN, avame ukuhlotshaniswa nabakhiqizi abathile kanye nobuchwepheshe bawo obuyimfihlo. Ngokuvamile, i-GaN 2 imelela isigaba sangaphambilini samashaja e-GaN asebenza kahle kwezentengiselwano, kuyilapho i-GaN 3 imelela izinto ezintsha nentuthuko yakamuva.

Izindawo Eziyinhloko Zokwehlukanisa:

Umehluko omkhulu phakathi kwamashaja e-GaN 2 ne-GaN 3 uvame ukutholakala kulezi zindawo ezilandelayo:

1. Ukushintsha Imvamisa Nokusebenza Kahle:

Enye yezinzuzo eziyinhloko ze-GaN kune-silicon yikhono layo lokushintsha kuma-frequency aphezulu kakhulu. Le frequency yokushintsha ephezulu ivumela ukusetshenziswa kwezingxenye ezincane ezikhuthazayo (njenge-transformers nama-inductor) ngaphakathi kweshaja, okunegalelo elikhulu ekwehleni kosayizi nesisindo sayo. Ubuchwepheshe be-GaN 3 buvame ukusunduza la ma-frequency okushintsha aphakeme kakhulu kune-GaN 2.

Ukwanda kwemvamisa yokushintsha kumiklamo ye-GaN 3 kuvame ukuholela ekusebenzeni kahle kokuguqulwa kwamandla okuphezulu nakakhulu. Lokhu kusho ukuthi iphesenti elikhulu lamandla kagesi athathwe endaweni yokukhipha udonga empeleni alethwa kudivayisi exhunyiwe, amandla amancane alahleka njengokushisa. Ukusebenza kahle okuphezulu akugcini nje ngokunciphisa ukungcola kwamandla kodwa futhi kunegalelo ekusebenzeni okupholile kweshaja, okungenzeka kwandise isikhathi sayo sokuphila futhi kuthuthukise ukuphepha.

2. Ukuphathwa Kokushisa:

Nakuba i-GaN ngokwemvelo ikhiqiza ukushisa okuncane kune-silicon, ukuphatha ukushisa okukhiqizwa emazingeni aphezulu wamandla kanye namaza okushintshana kusalokhu kuyisici esibalulekile sokuklama ishaja. Ukuthuthukiswa kwe-GaN 3 kuvame ukufaka amasu okuphatha ukushisa athuthukisiwe ezingeni le-chip. Lokhu kungabandakanya ukwakheka kwe-chip okulungiselelwe, izindlela zokusabalalisa ukushisa ezithuthukisiwe ngaphakathi kwe-transistor ye-GaN uqobo, kanye nezindlela zokuzwa nokulawula ukushisa ezihlanganisiwe.

Ukuphathwa okungcono kokushisa kumashaja e-GaN 3 kuvumela ukuthi asebenze ngokuthembekile ekukhishweni kwamandla aphezulu kanye nemithwalo eqhubekayo ngaphandle kokushisa ngokweqile. Lokhu kuzuzisa kakhulu kumadivayisi afuna ukushaja njengama-laptop namathebulethi.

3. Ukuhlanganiswa kanye Nobunzima:

Ubuchwepheshe be-GaN 3 buvame ukuhilela izinga eliphezulu lokuhlanganiswa ngaphakathi kwe-GaN power IC (Integrated Circuit). Lokhu kungafaka phakathi ukufaka izifunda zokulawula ezengeziwe, izici zokuvikela (njengokuvikela i-over-voltage, i-over-current, kanye nokushisa okuphezulu), ngisho nabashayeli besango ngqo ku-chip ye-GaN.

Ukuhlanganiswa okwandisiwe kumiklamo ye-GaN 3 kungaholela emiklamo elula yokushaja iyonke enezingxenye ezimbalwa zangaphandle. Lokhu akugcini nje ngokunciphisa i-bill yezinto zokwakha kodwa futhi kungathuthukisa ukuthembeka futhi kufake isandla ekwenzeni kube lula. Izifunda zokulawula eziyinkimbinkimbi kakhulu ezihlanganiswe kuma-chips e-GaN 3 zingavumela futhi ukulethwa kwamandla okunembile nokuphumelelayo kudivayisi exhunyiwe.

4. Ubuningi Bamandla:

Ubuningi bamandla, obulinganiswa ngama-watts nge-cubic inch (W/in³), buyindlela ebalulekile yokuhlola ukuqina kwe-adaptha yamandla. Ubuchwepheshe be-GaN, ngokuvamile, buvumela ubuningi bamandla obuphezulu kakhulu uma kuqhathaniswa ne-silicon. Ukuthuthukiswa kwe-GaN 3 kuvame ukusunduza lezi zibalo zobuningi bamandla nakakhulu.

Ukuhlanganiswa kwamaza okushintsha aphezulu, ukusebenza kahle okuthuthukisiwe, kanye nokuphathwa kokushisa okuthuthukisiwe kumashaja e-GaN 3 kwenza abakhiqizi bakwazi ukudala ama-adaptha amancane nanamandla kakhulu uma kuqhathaniswa nalawo asebenzisa ubuchwepheshe be-GaN 2 ukuze kuphume amandla afanayo. Lokhu kuyinzuzo enkulu yokuphatheka kalula kanye nokulula.

5. Izindleko:

Njenganoma yiluphi ubuchwepheshe obushintshayo, izizukulwane ezintsha zivame ukuza nezindleko zokuqala eziphezulu. Izingxenye ze-GaN 3, njengoba zithuthuke kakhulu futhi zingase zisebenzise izinqubo zokukhiqiza eziyinkimbinkimbi kakhulu, zingase zibize kakhulu kunezinye ze-GaN 2. Kodwa-ke, njengoba ukukhiqizwa kukhula futhi ubuchwepheshe buqala ukwanda, umehluko wezindleko kulindeleke ukuthi unciphe ngokuhamba kwesikhathi.

Ukuhlonza Amashaja e-GaN 2 kanye ne-GaN 3:

Kubalulekile ukuqaphela ukuthi abakhiqizi abawabeki amalebula njalo amashaja abo ngokuthi "i-GaN 2" noma "i-GaN 3." Kodwa-ke, ungavame ukuphetha ngokuthi ubuchwepheshe be-GaN busetshenziswa ngokusekelwe ezicacisweni zeshaja, usayizi, kanye nosuku lokukhishwa kwayo. Ngokuvamile, amashaja amasha anamandla amakhulu kakhulu kanye nezici ezithuthukisiwe cishe azosebenzisa i-GaN 3 noma izizukulwane ezizayo.

Izinzuzo Zokukhetha Ishaja Ye-GaN 3:

Nakuba amashaja e-GaN 2 kakade enikeza izinzuzo ezibalulekile kune-silicon, ukukhetha ishaja ye-GaN 3 kunganikeza izinzuzo ezengeziwe, okuhlanganisa:

• Umklamo Omncane Futhi Olula Kakhulu: Jabulela ukuphatheka okukhulu ngaphandle kokudela amandla.
• Ukusebenza Kahle Kakhulu: Nciphisa ukulahlwa kwamandla futhi kungenzeka kwehlise izikweletu zikagesi.
• Ukusebenza Okuthuthukisiwe Kokushisa: Thola ukusebenza okupholile, ikakhulukazi ngesikhathi sokushaja okunzima.
• Ukushaja Okusheshayo Okungenzeka (Ngokungaqondile): Ukusebenza kahle okuphezulu kanye nokuphathwa okungcono kokushisa kungavumela ishaja ukuthi ikwazi ukulondoloza amandla aphezulu isikhathi eside.
• Izici Ezithuthukisiwe Ezengeziwe: Zuza ezindleleni zokuvikela ezihlanganisiwe kanye nokulethwa kwamandla okulungiselelwe.

Ukushintsha kusuka ku-GaN 2 kuya ku-GaN 3 kumele isinyathelo esibalulekile ekuthuthukisweni kobuchwepheshe be-adaptha yamandla ye-GaN. Ngenkathi zombili izizukulwane zinikeza ukuthuthuka okukhulu kunezishaja ze-silicon zendabuko, i-GaN 3 ivame ukuletha ukusebenza okuthuthukisiwe maqondana nokuvama kokushintsha, ukusebenza kahle, ukuphathwa kokushisa, ukuhlanganiswa, futhi ekugcineni, ubuningi bamandla. Njengoba ubuchwepheshe buqhubeka nokuvuthwa futhi bufinyeleleka kalula, izishaja ze-GaN 3 zilungele ukuba yindinganiso evelele yokulethwa kwamandla okusebenza okuphezulu, okuhlangene, okunikeza abathengi ulwazi lokushaja olulula kakhulu nolusebenza kahle kakhulu kumadivayisi abo ahlukahlukene kagesi. Ukuqonda lokhu kungafani kunika abathengi amandla okwenza izinqumo ezinolwazi lapho bekhetha i-adaptha yabo yamandla elandelayo, ukuqinisekisa ukuthi bayazuza ekuthuthukisweni kwakamuva kobuchwepheshe bokushaja.
