He tika kia whiwhi te hōiho pai i tētahi nohoanga pai! Hei whakamahi katoa i ngā painga o ngā taputapu SiC, me hono hoki te pūnaha ara iahiko ki ngā pūnga hiko e tika ana. Mai i te mana whakahaere matua i roto i ngā waka hiko ki ngā āhuatanga hiko hou e kaha ana te hiko pērā i ngā inverters photovoltaic, kei te piki haere te rongonui o ngā pūnga hiko kiriata, ā, e hiahia nui ana te mākete ki ngā hua utu nui.
Nō nā tata nei, i whakarewahia e Shanghai Yongming Electronic Co., Ltd. ngā pūnga kiriata tautoko DC, e whā ngā painga nui e pai ai mō ngā IGBT o te whitu o ngā whakatipuranga a Infineon. Ka āwhina hoki ēnei ki te whakatau i ngā wero o te pumau, te pono, te whakaitiiti, me te utu i roto i ngā pūnaha SiC.
Tata ki te 90% te urunga o ngā pūnga kiriata ki ngā mahi puku matua. He aha i hiahiatia ai ēnei e te SiC me te IGBT?
I ngā tau tata nei, me te tere o te whanaketanga o ngā ahumahi pūngao hou pēnei i te rokiroki pūngao, te utu, me ngā waka hiko (EV), kua tere te piki haere o te hiahia mō ngā pūngao DC-Link. He māmā noa iho, ka mahi ngā pūngao DC-Link hei ārai i roto i ngā ara iahiko, e mimiti ana i ngā iahiko pāorooro teitei mai i te pito pahi me te whakangawari i te ngaohiko pahi, ā, ka tiakina ngā pana IGBT me SiC MOSFET mai i ngā iahiko pāorooro teitei me ngā pānga ngaohiko tauwhiro.
Ko te tikanga, ka whakamahia ngā pūnga hiko konumohe i roto i ngā tono tautoko DC. Heoi, i te pikinga o te ngaohiko pahi o ngā waka hiko hou mai i te 400V ki te 800V me ngā pūnaha photovoltaic e neke ana ki te 1500V me te 2000V rānei, kei te tino piki haere te hiahia mō ngā pūnga kiriata.
E whakaatu ana ngā raraunga i te tau 2022, ko te kaha tāuta o ngā inverters puku hiko i runga i ngā pūnga kiriata DC-Link i eke ki te 5.1117 miriona waeine, e 88.7% o te kaha tāuta katoa o ngā mana hiko. Ko ngā kamupene whakahaere hiko matua pērā i a Fudi Power, Tesla, Inovance Technology, Nidec, me Wiran Power e whakamahi ana i ngā pūnga kiriata DC-Link i roto i ā rātou inverters puku, me te ōwehenga kaha tāuta katoa tae atu ki te 82.9%. E tohu ana tēnei kua whakakapia ngā pūnga kiriata i ngā pūnga hikohiko hei matua i roto i te mākete puku hiko.
Nā te mea ko te ātete ngaohiko mōrahi o ngā pūnga hiko konumohe he tata ki te 630V. I roto i ngā tono ngaohiko teitei me te mana nui i runga ake i te 700V, me hono ngā pūnga hiko maha i roto i te raupapa me te whakarara kia tutuki ai ngā whakaritenga whakamahinga, ka hua ake he mate pūngao, he utu BOM, me ngā take pono.
E whakaatu ana tētahi pepa rangahau mai i Te Whare Wānanga o Mareia e whakamahia ana ngā pūnga hiko i roto i te hononga DC o ngā inverters haurua-piriti IGBT silicon, engari ka puta pea ngā ngaru hiko nā te ātete raupapa ōrite teitei (ESR) o ngā pūnga hiko. Ki te whakatauritea ki ngā otinga IGBT e hangai ana ki te silicon, he teitei ake ngā auau whakawhiti o ngā SiC MOSFET, ka hua ake he nui ake ngā kaha ngaru hiko i roto i te hononga DC o ngā inverters haurua-piriti. Ka taea e tēnei te arahi ki te hekenga o te mahi a te taputapu, ki te kino rānei, nā te mea ko te auau resonant o ngā pūnga hiko he 4kHz noa iho, kāore e ranea ki te mimiti i te ripple o ia o ngā inverters SiC MOSFET.
Nō reira, i roto i ngā tono DC me ngā whakaritenga pono teitei ake, pērā i ngā inverters puku hiko me ngā inverters photovoltaic, ko ngā pūnga kiriata te mea e whiriwhiria ana. Ki te whakatauritea ki ngā pūnga electrolytic konumohe, ko ngā painga o ā rātou mahi ko te ātete ngaohiko teitei ake, te ESR iti iho, te kore polarity, te mahi pumau ake, me te roa ake o te ora, e taea ai te hoahoa pūnaha pono ake me te ātete ripple kaha ake.
Hei tāpiritanga, mā te whakamahi i ngā pūnga kiriata i roto i te pūnaha ka taea te whakamahi tonu i ngā painga auau-tiketike, iti-ngaronga o ngā SiC MOSFET, ka whakaiti nui i te rahi me te taumaha o ngā wāhanga kore mahi (ngā inductor, ngā transformer, ngā pūnga) i roto i te pūnaha. E ai ki ngā rangahau a Wolfspeed, e 22 ngā pūnga hiko konumohe e hiahiatia ana e te inverter IGBT 10kW e hangai ana ki te silicon, engari e 8 noa iho ngā pūnga kiriata e hiahiatia ana e te inverter SiC 40kW, ka whakaiti nui i te horahanga PCB.
Ka Whakarewahia e YMIN ngā Pūnga Kiriata Hou me ngā Painga Nui e Whā hei Tautoko i te Ahumahi Pūngao Hou
Hei whakatutuki i ngā hiahia nui o te mākete, kua whakarewahia e YMIN ngā raupapa MDP me MDR o ngā pūnga kiriata tautoko DC. Mā te whakamahi i ngā tukanga hanga matatau me ngā rauemi kounga teitei, he tino hototahi ēnei pūnga ki ngā whakaritenga whakahaere o ngā SiC MOSFET me ngā IGBT e hangai ana ki te silicon mai i ngā kaiārahi hiko semiconductor o te ao pērā i a Infineon.
He maha ngā āhuatanga rongonui o ngā pūnga kiriata raupapa MDP me te MDR a YMIN: he iti ake te ātete raupapa ōrite (ESR), he teitei ake te ngaohiko whakatauranga, he iti ake te ia turuturu, me te pumau pāmahana teitei ake.
Tuatahi, he iti te hoahoa ESR o ngā pūnga kiriata a YMIN, e whakaiti ana i te ahotea ngaohiko i te wā e whakawhiti ana i ngā SiC MOSFET me ngā IGBT e hangai ana ki te silicon, ā, mā reira ka whakaitihia ngā ngaronga pūnga me te whakapai ake i te pai o te pūnaha whānui. Hei tāpiri, he teitei ake te ngaohiko whakatauranga o ēnei pūnga, ka taea te tu atu i ngā āhuatanga ngaohiko teitei ake me te whakarite i te mahi pumau o te pūnaha.
Ko ngā raupapa MDP me MDR o ngā pūnga kiriata YMIN e tuku ana i ngā awhe kaha o te 5uF-150uF me te 50uF-3000uF, me ngā awhe ngaohiko o te 350V-1500V me te 350V-2200V.
Tuarua, he iti ake te ia turuturu o ngā pūnga kiriata hou a YMIN, ā, he nui ake te pumau o te pāmahana. Mō ngā pūnaha whakahaere hiko waka hiko, he nui te mana, ka pā nui te wera e puta mai ana ki te roa o te ora me te pono o ngā pūnga kiriata. Hei whakatika i tēnei, ka whakauruhia e te raupapa MDP me te MDR mai i YMIN ngā rauemi kounga teitei me ngā tikanga hanga matatau hei hoahoa i tētahi hanganga wera pai ake mō ngā pūnga. Mā tēnei ka pumau te mahi ahakoa i roto i ngā taiao pāmahana teitei, ka ārai i te hekenga uara pūnga, te rahunga rānei nā te pikinga o te pāmahana. Hei tāpiri, he roa ake te roa o te ora o ēnei pūnga, ka whakarato i te tautoko pono ake mō ngā pūnaha hiko mana.
Tuatoru, he iti ake te rahi o ngā pūnga hiko MDP me MDR mai i YMIN, ā, he nui ake te kaha o te hiko. Hei tauira, i roto i ngā pūnaha taraiwa hiko 800V, ko te ia o te whakamahi i ngā taputapu SiC hei whakaiti i te rahi o ngā pūnga hiko me ētahi atu wāhanga kore mahi, ā, ka whakatairanga i te whakaitiiti i ngā mana hiko. Kua whakamahia e YMIN te hangarau hanga kiriata auaha, e kore e whakanui noa i te whakaurunga me te whai huatanga o te pūnaha whānui engari ka whakaitihia hoki te rahi me te taumaha o te pūnaha, ka whakarei ake i te kawe me te ngāwari o ngā taputapu.
I te nuinga o te wā, ka tukuna e te raupapa pūnga kiriata DC-Link a YMIN he whakapainga 30% i roto i te kaha tu atu ki te dv/dt me te pikinga 30% i roto i te roanga o te ora ki te whakataurite ki ētahi atu pūnga kiriata kei te mākete. Ehara i te mea ka pai ake te pono o ngā ara iahiko SiC/IGBT engari ka pai ake hoki te whai hua o te utu, ka wikitoria i ngā arai utu i roto i te whakamahinga whānui o ngā pūnga kiriata.
Hei paionia o te umanga, kua neke atu i te 20 tau a YMIN e whai wāhi nui ana ki te ao o ngā pūnga hiko. Kua roa te whakamahinga o ana pūnga hiko teitei ki ngā mara teitei pēnei i te OBC onboard, ngā puranga utu hiko hou, ngā kaitahuri photovoltaic, me ngā karetao ahumahi. Ka whakatauhia e tēnei whakatupuranga hou o ngā hua pūnga hiko kiriata ngā wero maha i roto i te whakahaere tukanga whakaputa pūnga hiko kiriata me ngā taputapu, kua oti te tiwhikete pono me ngā umanga matua o te ao, ā, kua tutuki i te tono tauine nui, e whakaatu ana i te pono o te hua ki ngā kiritaki nui ake. I te heke mai, ka whakamahia e YMIN tana kohikohinga hangarau mo te wā roa hei tautoko i te whanaketanga tere o te umanga hiko hou me ngā hua pūnga hiko pono me te utu iti.
