Hei whakatutuki i te mahi tino pai o te pūtake hiko papamahi, he mea nui kia mārama ki ōna mātāpono taketake. Ka hurihia e te pūtake hiko papamahi te mana whakauru AC mai i te putanga pakitara ki te mana DC e whakamahia ana hei whakakaha i ngā wāhanga rerekē i roto i te rorohiko. I te nuinga o te wā ka mahi i runga i te urunga AC kotahi-wāhanga, ā, ka whakarato i ngā ngaohiko putanga DC maha, pērā i te +12V, -12V, +5V, me te +3.3V.
Hei huri i te mana whakauru AC ki te mana DC, ka whakamahia e te pūtake hiko papamahi he whakawhiti hiko hei huri i te mana whakauru AC ngaohiko teitei me te iahiko iti ki te tohu AC ngaohiko iti me te iahiko teitei. Kātahi ka whakatikatikaina tēnei tohu AC mā te whakamahi i ngā diode, e huri ai i te tohu AC ki te ngaohiko DC pupuhi.
Hei whakangawari i te ngaohiko DC e pupuhi ana, ka whakamahia e te pūtake hiko papamahi ngā pūnga e penapena ana i te utu nui ka tukuna i ngā wā o te ngaohiko iti, ka hua ake he ngaohiko putanga DC pumau ake. Kātahi ka whakatikatikaina te ngaohiko DC mā te whakamahi i tētahi ara iahiko whakahaere ngaohiko kia mau tonu ai i roto i ngā manawanui pakari, kia kore ai e kino ki ngā wāhanga. He maha ngā parenga, pērā i te parenga ngaohiko nui, te parenga iahiko nui, me te parenga ara iahiko poto, kua hangaia hoki ki roto i ngā pūtake hiko papamahi hei ārai i te kino ki ngā wāhanga mēnā he hapa.
Mā te mārama ki ngā mātāpono taketake o tētahi pūtake hiko papamahi ka āwhina i te whiriwhiri i te pūtake hiko e tika ana mō te pūnaha rorohiko, me te whakarite hoki i te mahi tino pai.
I roto i tēnei tuhinga, ka hipokina e mātou ngā kaupapa matua o te pūtake hiko papamahi, me pēhea te whakamahi tika, me ngā mea hei tirotiro māu i te wā e whiriwhiri ana i tētahi tauira.
He aha te Pūtake Hiko Paepae?
Ina mahi koe i tētahi kaupapa e hiahia ana ki te nui tika o te hiko DC, he mea whai hua te pūtake hiko papamahi. He pūtake hiko iti tēnei kua hangaia kia noho ki runga i tō tēpu mahi.
E mōhiotia ana hoki ēnei taputapu ko ngā pūhiko hiko taiwhanga, ngā pūhiko hiko DC, me ngā pūhiko hiko ka taea te whakarite. He tino pai ēnei mō ngā hikohiko mō te hunga e hiahia ana ki tētahi pūtake hiko pono, ngāwari hoki ki te whakamahi.
Ahakoa he maha ngā momo pūhiko papaaho e wātea ana – tae atu ki ngā mea he mahi whakawhitiwhiti kōrero, ngā momo putanga maha, me ngā mea he maha ngā āhuatanga – kua hangaia katoatia ēnei hei whakahaere i ō mahi kia māmā ake, kia tika ake hoki.
Me pēhea te mahi?
He taputapu maha ngā mahi a te pūhiko hiko papamahi e whakarato ana i te hiko kua whakaritea ki ngā taputapu hiko. Mā te tango i tētahi raina hiko AC mai i te pūtake hiko ka tātarihia kia puta he putanga DC pumau. He maha ngā wāhanga o te tukanga, tae atu ki te whakawhiti hiko, te whakatikatika hiko, te pūnga hiko, me te kaiwhakahaere hiko.
Hei tauira, i roto i te pūhiko hiko raina, ka whakahekehia e te whakawhiti hiko te ngaohiko ki te taumata e taea te whakahaere, ka hurihia e te whakatikatika te iahiko AC ki te DC, ka tātarihia e te pūnga iahiko te haruru e toe ana, ā, ka whakarite te kaiwhakahaere ngaohiko i te putanga DC pumau. Mā te kaha ki te whakarite i ngā taumata ngaohiko me te iahiko me te tiaki i ngā taputapu mai i te kaha nui, he taputapu nui te pūhiko hiko papamahi mō ngā pūnaha tirotiro aunoa, ngā āwhina whakangungu kura, me ētahi atu.
He aha te mea nui?
Ahakoa ehara te pūhiko hiko papamahi i te taputapu tino ataahua i roto i te taiwhanga hiko a te miihini hiko, kāore e taea te whakanui rawa i tōna hiranga. Ki te kore he pūhiko, kāore e taea te whakamātautau me te hanga tauira.
He pūtake hiko pono, pumau hoki ngā pūhiko hiko o te papa mahi hei whakamātautau me te whakakaha i ngā ara iahiko hiko. Mā ēnei ka taea e ngā kaihangarau te whakarerekē i te hiko me te iahiko ki ngā wāhanga hei whakamātautau i ō rātou rohe, hei tirotiro me pēhea te mahi i roto i ngā tono rerekē, me te whakarite kia tika te mahi i roto i te hua whakamutunga.
Ahakoa te āhua nei, ehara te haumi ki tētahi pūhiko hiko kounga teitei i te mea tino ātaahua. Heoi anō, ka taea e ia te whai pānga nui ki te angitu me te whai huatanga o te hoahoa me te whakawhanaketanga hiko.
