Kaiwhakahaere Pūngao Hiko MPPT Ngaohiko-Tiketike 192V–500V: He Huringa Whai Hua mō ngā Teihana Hiko Whenua-Nui me ngā Pūnaha Rokiroki Pūngao

Te whanaketanga hou i roto i te hangarau matua: Mai i te 'aroturuki mārama korekore' ki te 'arotautanga atamai'

Pūnaha Aroturuki Maha-Tihi: Mā te whakamahi i te tikanga whakapiki kawe hiko me te hangarau nekehanga taurangi gradient, ka tautuhia tika ngā pihi IV maha-tihi i puta mai i te atarangi, i te whakahekenga rānei o te kōwae. Mā te tango i a Bangzhao Electric Raupapa BZMC Hei tauira, ka tautokohia e tana tukatuka 32-moka te aroturukitanga takirua-tihi/maha-tihi, kia mau tonu ai te pūwāhi hiko mōrahi ā-ao ahakoa i raro i ngā āhuatanga atarangi.
Painga Hanganga Ngaohiko WhānuiKa taea e te awhe tāuru 192V–500V te whakatutuki i ngā whakaritenga pūnaha ngaohiko-tiketike. Ahakoa e hiahiatia ana e ngā pūmana 100V tuku iho he maha ngā aho raupapa, ka whakaitihia e te hoahoa ngaohiko-tiketike te maha o ngā aho whakarara, ka whakaitihia ngā ngaronga taura me ngā utu tāutanga. Ka whakaitihia e te tāuru DC ngaohiko-tiketike te whakamahinga taura mā te 30%, ka whakarei ake i te ōhanga pūnaha.
Hangarau Mana Mamati: Mā ngā kōwae IGBT e honoa ana ki te whakatikatika tukutahi maha-wāhanga ka eke ki te 99% te pai o te huringa, ka whakanui ake i te whakaputa hiko mā te 20%–25% ki te whakaritea ki ngā pūmana PWM. Mā te utu pāmahana whakauru (-3mV/℃/2V) ka roa ake te roa o te pākahiko, ā, mā te tiaki pāmahana nui ka whakaiti aunoa i te kawenga i te 45°C hei ārai i te kino o ngā taputapu mai i te wera nui.

Ngā otinga e hangai ana ki ngā horopaki: mai i ngā teihana hiko e hono ana ki te whatunga hiko ki te rokiroki hiko i waho o te whatunga hiko

Ngā teihana hiko whenua nui: Te whakamahi i te hoahoa MPPT hei aro atu ki ngā rerekētanga o te whakatakotoranga me ngā take atarangi hapa.
Ngā tuanui arumoni me ngā tuanui ahumahi: Mō ngā āhuatanga e herea ana te kawenga pērā i ngā taera maitai kua pania ki te tae me ngā tuanui karāhe, ka taea te whakatinanatanga māmā mā te whakamahi i ngā kōwae silicon tioata ngāwari (4kg/m²) me ngā pūmana ngaohiko teitei.
Ngā pūnaha whakarite rokiroki pūngao: I roto i ngā horopaki hononga DC ngāwari-rokiroki-whakaahua, Ngā pūmana MPPT mahi tahi me ngā pākahiko rokiroki hiko kia pai ai te whakaputa hiko.

Te 192V–500V kaiwhakahaere MPPT ngaohiko-tiketike kei te tautuhi anō i ngā rohe o te oranga ōhanga me te pono mō ngā pūnaha photovoltaic nui mā te auahatanga hangarau me te whanaketanga hohonu-tono motuhake. Mō ngā kaipupuri moni, te whiriwhiri i tētahi kaiwhakahaere ngaohiko teitei Ko te aroturuki i ngā tihi maha, te urutaunga ngaohiko whānui, me ngā āheinga taunga atamai e tohu ana i te ara matua ki te whakatutuki i ngā 'hokinga teitei ake me te whai huatanga pūngao pai rawa atu' i roto i ngā haumitanga matomato.
