Ko ngā kaiwhakahaere utu hiko pūngao rā, ko ngā kaiwhakahaere rānei, he taputapu e whakamahia ana i roto i ngā rama hiko-rā hei whakahaere i te iahiko e rere ana mai i te papa rā ki te pākahiko. Ko ngā kaiwhakahaere hiko pūngao rā anō hoki te kawenga mō te whakawhāiti i te iahiko e tangohia ana mai i te pākahiko ki te LED. I roto i te pūnaha rama pūngao rā, he mahi nui tā ngā kaiwhakahaere ki te whakahaere i te utu me te ngaohiko. Ina mutu te whakaputa hiko a ngā papa rā i te torengitanga o te rā, ka āwhina ngā kaiwhakahaere ki te huri i te LED.
Tērā pea ka rere whakamuri te hiko mai i te pākahiko ki ngā panera ina kore he au e puta i te pō, ka kino pea te roa o te ora o ngā pākahiko. Ka āwhina ngā kaiwhakahaere utu ki te aukati i tēnei rere hiko whakamuri mā te kimi i te wā kāore he whakaputa hiko me te momotu i ngā panera mai i ngā pākahiko kia kore ai e nui rawa te utu. Ka taea hoki e te nui rawa te utu te whakaiti i te roa o te ora o ngā pākahiko, ā, ka āwhina ngā kaiwhakahaere utu hou ki te whakaroa i te roa o te ora o te pākahiko mā te whakaiti i te nui o te au e tukuna ana ki te pākahiko ina kua tino utua, ā, ka āwhina hoki ki te huri i te ngaohiko nui ki te amperage.
He aha i hiahiatia ai ngā kaiwhakahaere i roto i ngā rama pūngao-rā?
●Hei whakahaere i te ngaohiko o te pākahiko
●Hei ārai i te rere o te au whakamuri
●Kia kore ai e nui rawa te utu, e iti rawa rānei te utu o ngā pākahiko
●Hei tohu i te wā e utua ana te pākahiko
Ngā momo kaiwhakahaere utu pūngao rā
Ngā kaiwhakahaere utu mō te whakarerekētanga whānui o te pāorooro (PWM)
Ko te PWM te kaiwhakahaere e whakamahia whānuitia ana nā te mea e whakamahi ana i te hangarau kua roa e whakamatautauria ana hei whakahaere i te rere o te iahiko. Ka puta te whakarerekētanga whānui o te pāorooro ina tae te pākahiko ki te taumata utu taurite mā te whakaiti haere i te iahiko. He raruraru noa te tuku-ā-unoa i roto i te nuinga o ngā pākahiko ka taea te whakahou, ina ngaro te mana ina utua katoatia. Ka tīmata anō te kaiwhakahaere PWM ki te tuku i te iti o te mana i ngā wā katoa kia mau tonu ai te utu o te pākahiko me te pupuri i te utu, kia kore ai e tuku-ā-unoa.
E kiia ana he tino pakari ngā pūmana PWM, ā, he pai te mahi i ngā āhuarangi mahana. He iti ake te utu, ā, e wātea ana i roto i ngā rahi maha mō ngā momo tono. Ki ngā pūmana PWM, he mea nui kia whai panera rā me ngā pākahiko e ōrite ana te ngaohiko. Ko te pūmana utu PWM te momo pūmana utu paerewa e whakamahia ana i roto i ngā rama tiriti rā, ā, he pai hoki mō ngā pūnaha rā iti me ngā panera me te pākahiko iti.
Ngā kaiwhakahaere utu aroturuki pūwāhi mana mōrahi (MPPT)
He kōwhiringa utu nui ake, he uaua ake hoki ngā pūmana MPPT mō ngā pūnaha hiko pūngao rā; heoi, ko tētahi o ngā painga nui o ēnei pūmana, he rerekē ki ngā pūmana PWM, ka taea e ngā pūmana MPPT te taurite i ngā ngaohiko kāore e taurite mai i ngā panera pūngao rā me ngā pākahiko. He mea hou te tikanga e whakamahia ana i roto i ngā pūmana MPPT e āhei ai ngā panera ki te mahi i tō rātou pūwāhi mana mōrahi. Nā te rerekētanga o te irahiko o te rā puta noa i te rā, ka rerekē pea te ngaohiko me te ia o te panera. Ka whakatikatikahia e ngā pūmana MPPT te ngaohiko kia puta ai te mana mōrahi ahakoa te āhua o te rangi.
He tere ake te utu a ngā pūmana MPPT, ā, he roa ake te roa o te ora. Ka taea e rātou te whakarerekē i tā rātou whakaurunga hei tīmata i te mana nui rawa atu mai i ngā panera. Ka taea e ēnei pūmana te whakarerekē i te mana putanga kia ōrite ki te mana o te pākahiko. E kitea ana he pai ake tā rātou mahi i ngā āhuarangi makariri, ā, e kiia ana he pai ake i ngā pūmana PWM.
Me pēhea te whiriwhiri i te kaiwhakahaere utu tika?
E whakamahia ana ngā pūmana utu PWM me MPPT i roto i te pūnaha rama tiriti o te rā. He taputapu tiaki ngā pūmana, ā, he mea pai rawa atu tēnei mai i tō waeine rā. I runga i ngā āhuatanga e whai ake nei, me whiriwhiri e koe he pūmana e hototahi ana ki te ngaohiko o tō pūnaha rā.
Te roanga o te ora o te kaiwhakahaere
Te wāhi tāutanga me ōna āhuatanga pāmahana
Ō hiahia pūngao me tō tahua
Te whai huatanga o ngā panera rā
Te rahi whānui o te pūnaha rama o te rā
Momo pākahiko e whakamahia ana i roto i te pūnaha rama rā
E ai ki te pikitia, he kaihanga ngaio a Zenith Lighting mō ngā momo rama tiriti katoa, ki te mea he pātai, he kaupapa rānei āu, tēnā kaua e mangere ki te whakapiri mai ki a mātou.
