Ukufika kwetekhnoloji yeGallium Nitride (GaN) kuyitshintshile indlela ezisebenza ngayo iiadaptha zamandla, nto leyo evumela ukuba kudalwe iitshaja ezincinci kakhulu, ezikhaphukhaphu, nezisebenza kakuhle kunezinye zemveli ezisebenzisa isilicon. Njengoko itekhnoloji ikhula, sibone ukuvela kwezizukulwana ezahlukeneyo zee-semiconductors zeGaN, ngakumbi iGaN 2 kunye neGaN 3. Nangona zombini zibonelela ngophuculo olukhulu kunesilicon, ukuqonda izinto ezingaphakathi kwezi zizukulwana zimbini kubalulekile kubathengi abafuna izisombululo zokutshaja eziphambili nezisebenzayo. Eli nqaku lijonga umahluko ophambili phakathi kweetshaja zeGaN 2 kunye neGaN 3, lihlola uphuhliso kunye neenzuzo ezibonelelwa lutshintsho lwamva nje.
Ukuze siqonde umahluko, kubalulekile ukuqonda ukuba "iGaN 2" kunye ne "GaN 3" azingomagama aqhelekileyo achazwa liqumrhu elinye elilawulayo. Endaweni yoko, amele ukuqhubela phambili kwiinkqubo zoyilo kunye nokuveliswa kwee-transistors zamandla zeGaN, ezihlala zinxulunyaniswa nabavelisi abathile kunye nobuchwepheshe babo obukhethekileyo. Ngokubanzi, iGaN 2 imele inqanaba langaphambili leetshaja zeGaN ezisebenza ngorhwebo, ngelixa iGaN 3 imele izinto ezintsha kunye nophuculo lwamva nje.
Iindawo eziphambili zoKwahlulahlula:
Umahluko ophambili phakathi kweetshaja zeGaN 2 kunye neGaN 3 uhlala ulele kwezi ndawo zilandelayo:
1. Ukutshintsha Ubuninzi kunye nokusebenza kakuhle:
Enye yezona nzuzo ziphambili zeGaN kunesilicon kukukwazi kwayo ukutshintsha kwiifrequencies eziphezulu kakhulu. Olu tshintsho luphezulu luvumela ukusetyenziswa kwezinto ezincinci ezibangela ukuguquguquka (ezifana neetransformers kunye nee-inductors) ngaphakathi kwitshaja, nto leyo enegalelo elikhulu kubungakanani bayo obuphantsi kunye nobunzima. Itekhnoloji yeGaN 3 ngokubanzi inyusa la friquencies okutshintsha ade abe phezulu kuneGaN 2.
Ukwanda kokutshintsha rhoqo kwiidizayini zeGaN 3 kudla ngokuthetha ukuba amandla ombane aphezulu nangakumbi. Oku kuthetha ukuba ipesenti enkulu yamandla ombane athathwe kwiplagi yodonga athunyelwa kwisixhobo esiqhagamshelweyo, amandla amancinci alahlekayo njengobushushu. Ukusebenza okuphezulu akunciphisi nje kuphela inkunkuma yamandla kodwa kukwanegalelo ekusebenzeni okupholileyo kwetshaja, okunokwandisa ubomi bayo kunye nokuphucula ukhuseleko.
2. Ulawulo lobushushu:
Nangona iGaN ivelisa ubushushu obuncinci kunesilicon ngokwemvelo, ukulawula ubushushu obuveliswa kumanqanaba aphezulu amandla kunye nokutshintsha amaza kuseyeyona nto ibalulekileyo kuyilo lwetshaja. Uphuhliso lweGaN 3 ludla ngokubandakanya iindlela zolawulo lobushushu eziphuculweyo kwinqanaba letshiphu. Oku kunokubandakanya uyilo lwetshiphu oluphuculweyo, iindlela zokusasaza ubushushu eziphuculweyo ngaphakathi kwe-transistor yeGaN ngokwayo, kunye neendlela ezinokuthi zihlanganiswe zokuva ubushushu kunye neendlela zokulawula.
Ulawulo olungcono lobushushu kwiitshaja zeGaN 3 lubavumela ukuba basebenze ngokuthembekileyo xa amandla aphezulu ephuma kwaye bethwala imithwalo engapheliyo ngaphandle kokugqithisa kakhulu. Oku kuluncedo ngakumbi kwizixhobo ezifuna ukutshaja ezifana neelaptops kunye neetablets.
3. Ukudibanisa kunye nobunzima:
Itekhnoloji yeGaN 3 idla ngokubandakanya inqanaba eliphezulu lokudibanisa ngaphakathi kwe-GaN power IC (Integrated Circuit). Oku kungabandakanya ukubandakanya iisekethe zolawulo ezingaphezulu, iimpawu zokhuseleko (ezifana nokukhusela i-over-voltage, i-over-current, kunye nobushushu obugqithisileyo), kwanabaqhubi beegeyithi ngqo kwi-chip yeGaN.
Ukwanda kokuhlanganiswa koyilo lweGaN 3 kunokukhokelela kuyilo lwetshaja olulula ngokubanzi olunezixhobo ezimbalwa zangaphandle. Oku akunciphisi nje kuphela i-bill yezinto kodwa kunokuphucula ukuthembeka kwaye kuncedise ngakumbi kwi-miniaturization. I-circuitry control circuitry eyinkimbinkimbi edityaniswe kwiitships zeGaN 3 inokwenza ukuba ukuhanjiswa kwamandla ngokuchanekileyo nangokufanelekileyo kwisixhobo esiqhagamshelweyo.
4. Ubuninzi bamandla:
Uxinano lwamandla, olulinganiswa ngeewatts nge-cubic intshi nganye (W/in³), luphawu oluphambili lokuvavanya ubuncinci beadaptha yamandla. Itekhnoloji yeGaN, ngokubanzi, ivumela uxinano lwamandla oluphezulu kakhulu xa kuthelekiswa nesilicon. Uphuhliso lweGaN 3 ludla ngokutyhalela phambili la manani oxinano lwamandla.
Ukudityaniswa kwamaza okutshintsha aphezulu, ukusebenza kakuhle okuphuculweyo, kunye nolawulo oluphuculweyo lobushushu kwiitshaja zeGaN 3 kwenza abavelisi bakwazi ukwenza iiadaptha ezincinci nezinamandla ngakumbi xa kuthelekiswa nezo zisebenzisa itekhnoloji yeGaN 2 yokukhupha amandla okufanayo. Eli lithuba elibalulekileyo lokuphatheka lula nokulula.
5. Ixabiso:
Njengakweminye iteknoloji eguqukayo, izizukulwana ezintsha zihlala zinexabiso eliphezulu lokuqala. Izinto zeGaN 3, ekubeni ziphucuke ngakumbi kwaye zinokusebenzisa iinkqubo zokuvelisa ezintsonkothileyo, zinokuba zibiza kakhulu kunezo zeGaN 2. Nangona kunjalo, njengoko imveliso ikhula kwaye iteknoloji isasazeka, umahluko weendleko kulindeleke ukuba unciphe ngokuhamba kwexesha.
Ukuchonga iitshaja zeGaN 2 kunye neGaN 3:
Kubalulekile ukuqaphela ukuba abavelisi abasoloko bebhala iitshaja zabo ngokucacileyo njenge "GaN 2" okanye "GaN 3." Nangona kunjalo, ungacinga ukuba isizukulwana sobuchwepheshe beGaN sisetyenzisiweyo sisekelwe kwiinkcukacha zetshaja, ubungakanani, kunye nomhla wokukhutshwa kwayo. Ngokubanzi, iitshaja ezintsha ezinamandla aphezulu kakhulu kunye neempawu eziphambili zinokusebenzisa iGaN 3 okanye izizukulwana ezizayo.
Iingenelo zokukhetha itshaja yeGaN 3:
Nangona iitshaja zeGaN 2 sele zibonelela ngeenzuzo ezibalulekileyo kunesilicon, ukukhetha itshaja yeGaN 3 kunokubonelela ngezinye izibonelelo, kubandakanya:
- Uyilo oluncinci nolukhaphukhaphu: Yonwabela ukuphatheka ngcono ngaphandle kokuncama amandla.
- Ukusebenza kakuhle: Kunciphisa inkcitho yamandla kwaye kunciphise iindleko zombane.
- Ukusebenza okuPhuculweyo koBushushu: Fumana amava okusebenza okupholileyo, ingakumbi xa utshaja kakhulu.
- Ukutshaja Okunokwenzeka Ngokukhawulezileyo (Ngokungathanga ngqo): Ukusebenza kakuhle okuphezulu kunye nolawulo olungcono lobushushu kunokuvumela itshaja ukuba ikwazi ukugcina amandla aphezulu ixesha elide.
- Iimpawu Eziphambili Ezingakumbi: Zuza kwiinkqubo zokhuselo ezidibeneyo kunye nokuhanjiswa kwamandla okuphuculweyo.
Utshintsho oluvela kwiGaN 2 ukuya kwiGaN 3 lubonisa inyathelo elibalulekileyo ekuphuhliseni ubuchwepheshe beadaptha yamandla yeGaN. Ngelixa zombini izizukulwana zibonelela ngophuculo olukhulu kuneetshaja zesilicon zemveli, iGaN 3 idla ngokunika ukusebenza okuphuculweyo ngokwexesha lokutshintsha, ukusebenza kakuhle, ulawulo lobushushu, ukuhlanganiswa, kwaye ekugqibeleni, uxinano lwamandla. Njengoko iteknoloji iqhubeka nokukhula kwaye ifikeleleka ngakumbi, iitshaja zeGaN 3 zikulungele ukuba ngumgangatho ophambili wokunikezelwa kwamandla okusebenzayo okuphezulu, okuncinci, okunika abathengi amava okutshaja alula nangcono kwiindidi ezahlukeneyo zezixhobo zabo ze-elektroniki. Ukuqonda la mahluko kunika abathengi amandla okwenza izigqibo ezinolwazi xa bekhetha iadaptha yabo yamandla elandelayo, ukuqinisekisa ukuba bayazuza kuphuhliso lwamva nje kwitekhnoloji yokutshaja.
