I ngā tau tata nei, ko te whanaketanga tere o ngā ahumahi pūngao hou pēnei i te rokiroki photovoltaic me ngā waka hiko (EV) kua piki ake te hiahia mō ngā pūnga DC-Link. I roto i te poto, he mahi nui tā ngā pūnga DC-Link i roto i te ara iahiko. Ka taea e rātou te mimiti i ngā iahiko pāorooro teitei i te pito pahi me te whakangawari i te ngaohiko pahi, kia tiakina ai ngā pana IGBT me SiC MOSFET mai i ngā pānga kino o ngā iahiko pāorooro teitei me ngā ngaohiko whakawhiti i te wā e whakahaerehia ana.
I te pikinga ake o te ngaohiko pahi o ngā waka hiko hou mai i te 400V ki te 800V, kua tino piki ake te hiahia mō ngā pūnga kiriata. E ai ki ngā raraunga, ko te kaha tāuta o ngā kaitahuri hiko e hangai ana ki ngā pūnga kiriata angiangi DC-Link i eke ki te 5.1117 miriona huinga i te tau 2022, e 88.7% o te kaha tāuta o te mana hiko. Ko ngā kaitahuri taraiwa o te maha o ngā kamupene whakahaere hiko matua pērā i a Tesla me Nidec e whakamahi ana i ngā pūnga kiriata DC-Link, e 82.9% o te kaha tāuta, ā, kua noho hei whiringa matua i roto i te mākete taraiwa hiko.
E whakaatu ana ngā pepa rangahau i roto i ngā kaitahuri haurua-piriti IGBT silicon, ko ngā pūnga hiko tuku iho te nuinga o te wā e whakamahia ana i roto i te hononga DC, engari ka puta he ngaru hiko nā te nui o te ESR o ngā pūnga hiko. Ki te whakatauritea ki ngā otinga IGBT e hangai ana ki te silicon, he teitei ake te auau whakawhiti o ngā SiC MOSFET, nō reira he teitei ake te kaha o te ngaru hiko i roto i te hononga DC o te kaitahuri haurua-piriti, ka heke pea te mahi a te taputapu, ka kino rānei, ā, ko te auau oro o ngā pūnga hiko he 4kHz anake, kāore e ranea ki te mimiti i te ngaru o ia o ngā kaitahuri SiC MOSFET.
Nō reira, i roto i ngā tono DC pērā i ngā inverters puku hiko me ngā inverters photovoltaic me ngā whakaritenga pono teitei ake,ngā pūnga kiriatako te nuinga o te wā ka whiriwhiria. Ki te whakatauritea ki ngā pūnga hiko konumohe, ko ō rātou painga mahi he ātete ngaohiko teitei ake, he iti ake te ESR, he kore-polarity, he pumau ake te mahi, me te roa ake o te ora, nā reira ka tutuki he ātete ripple kaha ake me te hoahoa pūnaha pono ake.
Ka taea e ngā pūnaha e whakamahi ana i ngā pūnga hiko angiangi te whakamahi i te auau teitei me te iti o te ngaronga o ngā MOSFET SiC, ā, ka whakaiti i te rahi me te taumaha o ngā wāhanga kore mahi. E whakaatu ana ngā rangahau a Wolfspeed e 22 ngā pūnga hiko konumohe e hiahiatia ana e te kaitahuri IGBT 10kW e hangai ana ki te silicon, ko te kaitahuri SiC 40kW e 8 noa iho ngā pūnga hiko angiangi e hiahiatia ana e te kaitahuri, ā, ka tino whakaitihia hoki te horahanga PCB.
Hei whakautu i te tono a te mākete, i whakarewahia e YMIN Electronics teRaupapa MDP o ngā pūnga kiriata, e whakamahi ana i ngā hangarau matatau me ngā rauemi kounga teitei hei urutau ki te SiC MOSFET me te IGBT e hangai ana ki te silicon. Ko ngā pūnga iahiko raupapa MDP he iti te ESR, he teitei te ngaohiko ātete, he iti te ia turuturu me te pumau pāmahana teitei.
Ngā Painga o ngā hua pūnga kiriata a YMIN Electronics:
Ko te hoahoa pūnga kiriata a YMIN Electronics e whakamahi ana i te ariā ESR iti hei whakaiti i te ahotea ngaohiko me te ngaronga pūngao i te wā whakawhiti me te whakapai ake i te whai huatanga o te pūngao pūnaha. He teitei te whakatauranga o te ngaohiko, ka urutau ki ngā taiao ngaohiko teitei, ā, ka whakarite i te pumau o te pūnaha.
Ko te whānuitanga o te kaha o ngā pūnga iahiko raupapa MDP kei waenganui i te 1uF ki te 500uF me te whānuitanga ngaohiko kei waenganui i te 500V ki te 1500V. He iti ake te ia turuturu me te pumau pāmahana teitei ake. Mā roto i ngā rauemi kounga teitei me ngā tukanga matatau, kua hangaia he hanganga whakamarara wera whai hua hei whakarite i te mahi pumau i ngā pāmahana teitei, te whakaroa i te roa o te ratonga, me te whakarato tautoko pono mō ngā pūnaha hiko mana. I taua wā anō, ko teNgā pūnga iahiko raupapa MDPhe kiato te rahi, he nui te kaha o te hiko, ā, e whakamahi ana i ngā tukanga hanga kiriata angiangi auaha hei whakapai ake i te whakaurunga me te whai huatanga o te pūnaha, hei whakaiti i te rahi me te taumaha, hei whakanui ake i te kawe me te ngāwari o ngā taputapu.
Ko te raupapa pūnga kiriata YMIN Electronics DC-Link kua piki ake i te 30% te manawanui dv/dt me te 30% te roa o te ratonga, e whakapai ake ana i te pono o ngā ara iahiko SiC/IGBT, e hua ake ai te whai huatanga utu, ā, e whakatau ana i te raruraru utu.
