Nā te taenga mai o te hangarau Gallium Nitride (GaN) kua hurihia te ao o ngā taputapu hiko, ā, kua taea ai te hanga i ngā taputapu utu he iti ake, he māmā ake, he pai ake hoki i ō rātou hoa tuku iho e hangai ana ki te silicon. I te whanaketanga o te hangarau, kua kite tātou i te putanga mai o ngā whakatupuranga rerekē o ngā semiconductors GaN, ko te mea tino rongonui ko te GaN 2 me te GaN 3. Ahakoa he nui ngā whakapainga e tukuna ana e rāua i runga i te silicon, he mea nui te mārama ki ngā āhuatanga rerekē i waenganui i ēnei whakatupuranga e rua mō ngā kaihoko e rapu ana i ngā otinga utu tino matatau me te tino whai hua. Ka rukuhia e tēnei tuhinga ngā rerekētanga matua i waenganui i ngā taputapu utu GaN 2 me te GaN 3, me te tūhura i ngā whanaketanga me ngā painga e tukuna ana e te putanga hou.
Hei mārama ki ngā rerekētanga, he mea nui kia mārama ko "GaN 2" me "GaN 3" ehara i te kupu paerewa whānui e tautuhia ana e te whakahaere kotahi. Engari, e tohu ana rāua i ngā whanaketanga i roto i ngā tukanga hoahoa me te hanga o ngā transistors mana GaN, e hono pinepine ana ki ngā kaihanga motuhake me ā rātou hangarau motuhake. I te nuinga o te wā, ko GaN 2 te wāhanga o mua o ngā rihi GaN e whai hua ana ki te hokohoko, ko GaN 3 ia e whakaatu ana i ngā auahatanga me ngā whakapainga hou ake.
Ngā Wāhanga Matua o te Rerekētanga:
Ko ngā rerekētanga matua i waenga i ngā rihi GaN 2 me GaN 3 kei roto i ēnei wāhanga e whai ake nei:
1. Auautanga me te Whai Hua o te Whakawhiti:
Ko tētahi o ngā painga matua o GaN i runga i te silicon ko tōna kaha ki te whakawhiti i ngā auau teitei ake. Mā tēnei auau whakawhiti teitei ake ka taea te whakamahi i ngā wāhanga iti ake te whakauru (pērā i ngā transformer me ngā inductors) i roto i te rihi, ka whai wāhi nui ki tōna rahi me tōna taumaha iti ake. Ko te hangarau GaN 3 te nuinga o te wā ka panaia ēnei auau whakawhiti ki runga ake i te GaN 2.
Ko te pikinga ake o te auau whakawhiti i roto i ngā hoahoa GaN 3 ka hua ake he pai ake te huringa mana. Ko te tikanga o tēnei he nui ake te ōrau o te pūngao hiko e tangohia ana mai i te putanga pakitara ka tukuna ki te taputapu hono, me te iti ake o te pūngao e ngaro ana hei wera. Ko te pai ake o te mahi ehara i te mea ka whakaiti noa i te moumou pūngao engari ka whai wāhi hoki ki te whakamatao ake i te mahi o te rihi, ka roa ake pea tōna roa me te whakarei ake i te haumaru.
2. Whakahaere Wera:
Ahakoa he iti ake te wera e whakaputaina ana e te GaN i te silicon, ko te whakahaere i te wera e whakaputaina ana i ngā taumata mana teitei ake me ngā auau whakawhiti he mea nui tonu i roto i te hoahoa rihi. He maha ngā wā ka whakauruhia e ngā whanaketanga GaN 3 ngā tikanga whakahaere wera kua whakapai ake i te taumata maramara. Ka uru pea tēnei ki ngā tahora maramara kua arotauhia, ngā ara whakamarara wera kua whakarei ake i roto i te transistor GaN tonu, me ngā tikanga tirotiro me te whakahaere pāmahana kua whakauruhia.
Mā te whakahaere wera pai ake o ngā rihi GaN 3 ka taea e rātou te mahi pono me ngā putanga hiko teitei ake me ngā kawenga pumau me te kore e wera rawa. He tino whai hua tēnei mō te utu i ngā taputapu e hiahia ana ki te hiko pērā i ngā pona me ngā papa.
3. Te Whakaurunga me te Uauatanga:
He maha ngā wā ka uru atu te hangarau GaN 3 ki tētahi taumata whakaurunga teitei ake i roto i te IC mana GaN (Porowhita Whakauru). Ka uru atu pea tēnei ki te whakauru i ētahi atu porowhita whakahaere, ngā āhuatanga tiaki (pēnei i te tiaki i te ngaohiko nui, te iahiko nui, me te pāmahana nui), tae atu ki ngā taraiwa kuaha tika ki runga i te maramara GaN.
Mā te whakaurunga nui ake ki ngā hoahoa GaN 3 ka taea te arahi ki ngā hoahoa rihi whānui kia māmā ake me te iti ake o ngā wāhanga o waho. Ehara i te mea ka whakaiti noa i te pire rauemi engari ka taea hoki te whakapai ake i te pono me te whai wāhi atu ki te whakaitiiti. Mā ngā ara iahiko whakahaere matatau ake kua whakauruhia ki roto i ngā maramara GaN 3 ka taea hoki te tuku hiko tika ake me te whai hua ake ki te taputapu hono.
4. Te Kīanga Mana:
Ko te mātotoru mana, e inehia ana i roto i ngā watts mō ia inihi kūpiko (W/in³), he inenga matua mō te aromatawai i te kiato o tētahi urutau mana. Ko te hangarau GaN, i te nuinga o te wā, ka taea te whakaputa i ngā mātotoru mana teitei ake i te silicon. Ko ngā whanaketanga GaN 3 te tikanga ka pana ake i ēnei tatauranga mātotoru mana ki tua atu.
Mā te whakakotahitanga o ngā auau whakawhiti teitei ake, te pai ake o te whai huatanga, me te whakahaere wera whakarei ake i roto i ngā rihi GaN 3, ka taea e ngā kaihanga te hanga i ngā urutau iti ake, kaha ake hoki, ki te whakaritea ki ērā e whakamahi ana i te hangarau GaN 2 mō te putanga mana kotahi. He painga nui tēnei mō te kawe me te watea.
5. Utu:
Pērā i ngā hangarau hou katoa, he nui ake te utu tīmatanga mō ngā whakatupuranga hou. Nā te mea he matatau ake, he uaua ake hoki ngā tukanga hangahanga o ngā wāhanga GaN 3, tera pea ka nui ake te utu i ō rātou hoa GaN 2. Heoi, i te mea ka nui haere te hanga, ka rongonui haere te hangarau, e matapaetia ana ka iti haere te rerekētanga utu i roto i te wā.
Te tautuhi i ngā utunga GaN 2 me GaN 3:
He mea nui kia mōhio koe kāore ngā kaihanga e tapaina ā-pūmau ana ā rātou rihi ko "GaN 2" ko "GaN 3" rānei. Heoi, ka taea e koe te whakatau i te whakatupuranga o te hangarau GaN e whakamahia ana i runga i ngā whakatakotoranga o te rihi, te rahi, me te rā tuku. Ko te tikanga, ko ngā rihi hou e whakamanamana ana i te kaha tino nui me ngā āhuatanga matatau ka nui ake te tūponotanga ki te whakamahi i te GaN 3, i ngā whakatupuranga o muri mai rānei.
Ngā Painga o te Kōwhiri i tētahi Rīhi GaN 3:
Ahakoa he nui ngā painga o ngā rihi GaN 2 i runga i te silicon, mā te whiriwhiri i tētahi rihi GaN 3 ka taea te whakarato i ētahi atu painga, tae atu ki:
- He hoahoa iti ake, he hoahoa māmā ake hoki: Kia pai te kawe, me te kore e whakaiti i te mana.
- Te Whakanui Ake i te Whai Hua: Te Whakaiti i te Paramanawa Hiko, me te whakaiti pea i ngā pire hiko.
- Te Mahi Wera Whakapai Ake: Kia mātao ake te whakamahinga, inā koa i ngā mahi utu uaua.
- Te Utu Tere Pea (Mā te Ārai): Mā te pai ake o te whai huatanga me te whakahaere wera pai ake ka taea e te rihi te pupuri i te putanga mana nui ake mō ngā wā roa.
- Ngā Āhuatanga Matatau Ake: Whai hua mai i ngā tikanga tiaki whakauru me te tuku hiko kua arotauhia.
Ko te whakawhiti mai i te GaN 2 ki te GaN 3 he taahiraa nui whakamua i roto i te whanaketanga o te hangarau urutau hiko GaN. Ahakoa he nui ngā whakapainga o ngā whakatipuranga e rua i ngā rihi silicon tuku iho, ko te GaN 3 te tikanga e whakarato ana i te mahi whakarei ake i runga i te auau whakawhiti, te whai huatanga, te whakahaere wera, te whakaurunga, me te mutunga, te kiato hiko. I te haere tonu o te whanaketanga o te hangarau me te ngāwari ake te uru atu, kua rite ngā rihi GaN 3 ki te noho hei paerewa matua mō te tuku hiko mahi-teitei, kiato, e tuku ana i tētahi wheako utu ngāwari ake, whai hua ake hoki ki ngā kaihoko mō ā rātou momo taputapu hiko. Mā te mārama ki ēnei rerekētanga ka taea e ngā kaihoko te whakatau whai whakaaro i te wā e whiriwhiri ana i tā rātou urutau hiko e whai ake nei, me te whakarite kia whai hua rātou i ngā whanaketanga hou o te hangarau utu.
