I te 26 o ngā rā, i pānuitia e Power Cube Semi te angitu o te whanaketanga o te mīhini haurua tuatahi o Kōrea ki te Tonga, he mea hanga ki te MOSFET 2300V SiC (Silicon Carbide).
Ki te whakatauritea ki ngā haurua hiko Si (Silicon) o nāianei, ka taea e te SiC (Silicon Carbide) te tu atu i ngā ngaohiko teitei ake, nō reira e kiia ana ko te taputapu o te whakatupuranga e whai ake nei e ārahi ana i te heke mai o ngā haurua hiko. He wāhanga nui e hiahiatia ana mō te whakauru i ngā hangarau hou, pērā i te horapa o ngā waka hiko me te whānui haere o ngā pokapū raraunga e whakahaerehia ana e te matauranga horihori.
He kamupene kore-pūkaha a Power Cube Semi e whakawhanake ana i ngā taputapu haurua hiko i roto i ngā wāhanga matua e toru: SiC (Silicon Carbide), Si (Silicon), me Ga2O3 (Gallium Oxide). Nō nā tata nei, i tono te kamupene, ā, i hoko atu i ngā Schottky Barrier Diodes (SBD) kaha-teitei ki tētahi kamupene waka hiko o te ao i Haina, ā, i rongonuihia mō tana hoahoa me te hangarau haurua hiko.
He mea whakamiharo te tukunga o te 2300V SiC MOSFET hei whanaketanga tuatahi i Korea ki te Tonga. I panuitia hoki e Infineon, he kamupene hiko haurua-ā-ao kei Tiamana, te whakarewatanga o tana hua 2000V i te marama o Poutū-te-rangi, engari kāore he raina hua 2300V.
Mā te whakamahi i te mōkihi TO-247PLUS-4-HCC, ka tutuki i te MOSFET 2000V CoolSiC a Infineon te hiahia mō te whakanui ake i te mātotoru o te mana i waenga i ngā kaihoahoa, me te whakarite kia pono te pūnaha ahakoa i raro i ngā āhuatanga tino uaua o te ngaohiko teitei me te auau whakawhiti.
He teitei ake te ngaohiko hononga iahiko tika a te CoolSiC MOSFET, e āhei ai te whakanui ake i te mana me te kore e whakanui ake i te iahiko. Koinei te taputapu silicon carbide motuhake tuatahi kei te mākete me te ngaohiko pakaru o te 2000V, e whakamahi ana i te mōkihi TO-247PLUS-4-HCC me te tawhiti toro o te 14mm me te ātea o te 5.4mm. He iti ngā mate whakawhiti o ēnei taputapu, ā, he pai mō ngā tono pēnei i ngā inverters aho rā, ngā pūnaha rokiroki pūngao, me te utu waka hiko.
He pai te raupapa hua CoolSiC MOSFET 2000V mō ngā pūnaha pahi DC ngaohiko teitei tae atu ki te 1500V DC. Ki te whakatauritea ki te 1700V SiC MOSFET, ka whakaratohia e tēnei taputapu he tawhē ngaohiko nui rawa atu mō ngā pūnaha DC 1500V. Ka tukuna e te CoolSiC MOSFET he ngaohiko paepae 4.5V, ā, kei roto hoki he diode tinana pakari mō te whakawhiti uaua. Mā te hangarau hononga .XT, ka tukuna e ēnei wāhanga he mahi wera tino pai me te ātete kaha ki te makuku.
Haunga te MOSFET CoolSiC 2000V, ka tukuna e Infineon ngā diode CoolSiC tāpiri kua takaihia ki roto i ngā kete TO-247PLUS 4-pin me TO-247-2 i te hauwhā tuatoru o te tau 2024 me te hauwhā whakamutunga o te tau 2024. He tino pai ēnei diode mō ngā tono pūngao rā. Kei te wātea hoki ngā huinga hua taraiwa kuaha e ōrite ana.
Kei te wātea inaianei te raupapa hua CoolSiC MOSFET 2000V i runga i te mākete. Hei tāpiri, kei a Infineon ētahi papa aromatawai e tika ana: EVAL-COOLSIC-2KVHCC. Ka taea e ngā kaiwhakawhanake te whakamahi i tēnei papa hei tūāpapa whakamātautau whānui tika hei aromatawai i ngā MOSFET CoolSiC katoa me ngā diode kua whakatauria ki te 2000V, tae atu ki te raupapa hua taraiwa kuaha wehe kotahi-hongere EiceDRIVER 1ED31xx mā te mahi rua-pāhekoheko, mahi tonu rānei.
I kī a Gung Shin-soo, te Āpiha Hangarau Matua o Power Cube Semi, "I taea e mātou te whakawhānui ake i ō mātou wheako o nāianei i roto i te whakawhanaketanga me te hanga papatipu o ngā MOSFET SiC 1700V ki te 2300V."
