Ka whai wāhi nui te whakaputa hiko photovoltaic o te rā ki te whakapaunga pūngao o te ao ā tōna wā, ehara i te mea hei whakakapi i ētahi puna pūngao tuku iho, engari hei puna matua hoki mō te tuku pūngao o te ao.
Ko ngā kaitahuri hiko photovoltaic he kaitahuri e huri ana i te ngaohiko DC rerekē i hangaia e ngā panera hiko photovoltaic (PV) ki te aukume hiko auau (AC), ka taea te whakahoki ki te pūnaha tuku arumoni, te whakamahi rānei i roto i te pūnaha kore-whatunga. Nā te mea he maha ngā wā ka whakamahia ngā kaitahuri hiko i waho, ā, me roa te wā e hiahiatia ana te mahi pono me te iti o te tiaki, he tino kaha ngā whakaritenga kounga me te pono mō ngā wāhanga e whakamahia ana i roto i ēnei taputapu e ngā kaiwhakamahi me ngā kaihoahoa. Hei kaikawe me te tautoko i roto i te tukanga hurihanga pūngao, he mea nui te mahi a ngā pūnga kiriata i roto i ngā āhuatanga katoa o ngā kaitahuri hiko photovoltaic. Ki te kore e whiriwhiria tika, ka pā kino ki te pumau me te roa o te ora o te taputapu.
Mō te whakamahinga i roto i te ara iahiko inverter, tirohia te tauira tono i te pikitia i raro nei:
Te mahi a te pūnga hononga-DC:
1) I roto i te ara iahiko inverter, ko te ngaohiko putanga o te whakatikatika ka whakangawarihia, ka tātarihia hoki;
2) Mimia te iahiko pupuhi kaha-teitei e tonoa ana e te inverter mai i "DC-Link", āraihia mai i te whakaputa i te ngaohiko pupuhi kaha-teitei ki te aukati o "DC-Link", me te pupuri i te piki me te heke o te ngaohiko i runga i te pahi DC i roto i te whānuitanga e whakaaetia ana;
3) Āraihia te kaha rawa o te ngaohiko me te kaha rawa o te ngaohiko o te "DC-Link" kei pā ki te IGBT.
Nō reira, ko ngā whakaritenga mō ngā pūnga:
1) Kia tino tika te kaha o te ngaohiko ātete
2) He nui te kaha
3) He rawaka te kaha o te iahiko nui, he iti rawa te ESR
4) Me pai ngā āhuatanga auau, me te iti rawa o te ESL
5) Whakamātauria te pāmahana teitei o waho me te haumākū teitei o te tono
Kua roa a Wuxi CRE New Energy Technology Co., Ltd. e arotahi ana ki te whakamahinga o ngā pūnga kiriata i roto i ngā hikohiko mana. E aro ana ki te āhua tono uaua i roto i ngā kaitahuri photovoltaic, e hangai ana ki te hangarau kiriata ātete-teitei tautokona e CRE DC, e whakamahi ana i te Polypropylene Dielectric ātete-pāmahana-teitei, he iti te ngaronga, kua hoahoa, kua whakawhanake hoki i tētahi raupapa o ngā pūnga kiriata me te ātete pāmahana me te haumākū teitei, te iti o te ESR (te whakaputa wera iti), te pono teitei me te roa o te ora.
I roto i ēnei, ko ngā āhuatanga mahi o te pūnga pahi DMJ-PS DC e whai ake nei:
Te pāmahana whakahaere mōrahi: 105 °C (pouaka kirihou)
Kāwai āhuarangi (IEC 60068-1:2013): 40/105/56
Hikohiko: Polypropylene (MKP)
Pouaka kirihou (UL 94 V-0)
Hiri kapia (UL 94 V-0)
Te uara kaha mōrahi 200μF
Awhe ngaohiko 300V~2000VDC
He pai te mahi whakaora-whaiaro, te ātete ki te ngaohiko nui, te ātete o nāianei teitei me te mate iti
Ātete ki te taiao wera me te haumākū (85℃/85%RH 1000h), he nui te pono, he roa te ora ratonga
Kia tutuki i ngā whakaritenga o te RoHS me te taumata AEC-Q200 mō ngā waka
