A: I te pikinga o te ngaohiko pahi mai i te 400V ki te 800V, ka tino piki ake ngā whakaritenga mō te ngaohiko ātete pūnga, te pai o te mimiti o te au riu, me te tohatoha wera. Ko ngā āhuatanga ESR iti me te ngaohiko ātete teitei o ngā pūnga kiriata he pai ake mō ngā taiao ngaohiko teitei.
Q3: He aha ngā painga matua o ngā pūnga kiriata i ngā pūnga hikohiko i roto i ngā waka hiko hou?
A: He teitei ake te ngaohiko ātete, he iti ake te ESR, he kore-porora, ā, he roa ake te roa o te ora. He teitei ake te auau oro i ērā o ngā pūnga hiko, e rite ana ki ngā whakaritenga whakawhiti auau-tiketike o ngā SiC MOSFET.
Q4: He aha i ngāwari ai te whakanui ake i ngā ngaohiko i roto i ngā inverters SiC e ētahi atu pūnga hiko?
A: Ko te ESR teitei me te auau iti o te oro e ārai ana i a rātou ki te mimiti pai i te ia oro oro oro oro teitei. Ina huri te SiC i ngā tere tere ake, ka piki ake ngā ngaru hiko, ka kino pea te taputapu.
Q5: Me pēhea te āwhina a ngā pūnga kiriata ki te whakaiti i te rahi o ngā pūnaha taraiwa hiko?
A: I roto i te rangahau take Wolfspeed, e waru noa iho ngā pūnga kiriata i hiahiatia mō te kaitahuri SiC 40kW (ki te whakaritea ki te 22 ngā pūnga hiko mō ngā IGBT e hangai ana ki te silicon), ā, ka tino whakaitihia te tapuwae PCB me te taumaha.
Q6: He aha ngā whakaritenga hou e pā ana ki ngā pūnga DC-Link e pā ana ki te auau whakawhiti teitei?
A: Me whakaiti te ESR hei whakaiti i ngā ngaronga whakawhiti, me teitei ake te auau oro hei pehi i te ngaru auau teitei, ā, me pai ake hoki te tū atu ki te dv/dt.
Q7: Me pēhea te aromatawai i te pono o te roa o te ora o ngā pūnga kiriata?
A: Kei te pumau o te rauemi i roto i te wera (hei tauira, te kiriata polypropylene) me te hoahoa whakamarara wera. Hei tauira, ka whakapai ake te raupapa YMIN MDP i te roa o te ora i ngā pāmahana teitei mā te arotau i te hanganga whakamarara wera.
Q8: He aha te pānga o te ESR o ngā pūnga kiriata ki te whai huatanga o te pūnaha?
A: Ka whakaitihia e te iti o te ESR te ngaronga pūngao i te wā whakawhiti, ka whakaitihia te ahotea ngaohiko, ā, ka whakapai ake i te pai o te inverter.
P9: He aha i pai ake ai ngā pūnga kiriata mō ngā taiao motuka wiri nui?
A: Ko tōna hanganga totoka, kāore he irahiko wai, he pai ake te ātete wiri ki te whakaritea ki ngā pūnga hiko, ā, nā te whakaurunga kore-polarity ka ngāwari ake.
Q10: He aha te tere uruhanga o nāianei o ngā pūnga kiriata i roto i ngā kaitahuri hiko?
A: I te tau 2022, i eke te kaha tāuta o ngā inverters kiriata-pūnga ki te 5.1117 miriona waeine, e 88.7% o te kaha tāuta katoa o ngā pūnaha whakahaere hiko. Ko ngā kamupene matua pērā i a Tesla me Nidec e 82.9%.
Q11: He aha i whakamahia ai hoki ngā pūnga kiriata i roto i ngā inverters photovoltaic?
A: He rite tonu ngā whakaritenga mō te pono me te roa o te ora ki ērā mō ngā tono motuka, ā, me tu atu hoki ki ngā piki me ngā heke o te pāmahana o waho.
P12: Me pēhea te aro atu a te raupapa MDP ki ngā take ahotea ngaohiko i roto i ngā ara iahiko SiC?
A: Mā te hoahoa iti o te ESR ka whakaitihia te kaha whakawhiti, ka whakapai ake i te ātete ki te dv/dt mā te 30%, ā, ka whakaitihia te mōrearea o te pakaru o te ngaohiko.
Q13: He pēhea te mahi a tēnei raupapa i ngā pāmahana teitei?
A: Mā te whakamahi i ngā rauemi pumau pāmahana teitei me te hanganga marara wera whai hua, ka whakarite mātou i te tere pirau kaha iti iho i te 5% i te 125°C.
Q14: Me pēhea te whakaiti i te rahi o te raupapa MDP?
A: Mā te hangarau angiangi auaha ka whakanui ake i te kaha mō ia wae rōrahi, ka nui ake te kiato mana i te toharite o te ahumahi, ka taea ai ngā hoahoa taraiwa hiko kiato.
Q15: He nui ake te utu tīmatanga o ngā pūnga kiriata i tērā o ngā pūnga hikohiko. He painga utu anō kei a rātou i roto i te huringa ora?
Āe. Ka roa te ora o ngā pūnga kiriata tae noa ki te roanga o te waka me te kore e whakakapia, engari me tiaki tonu ngā pūnga hiko. Mō te wā roa, he iti ake ngā utu katoa o ngā pūnga kiriata.
