I tēnei ao ahumahi me te hiko e tere whanake ana i ēnei rā, he mea nui te mahi a ngā pūhiko hiko DC hei whakarite i te pumau me te pono o te mahi puta noa i te whānuitanga o ngā tono — mai i te aunoatanga wheketere ki ngā whatunga whakawhitiwhiti kōrero, ngā taiwhanga whakamātautau, me ngā pūnaha pūngao.
He aha te Pūtake Hiko DC?
Ko te pūhiko hiko DC (Direct Current) he taputapu e tuku ana i te ngaohiko tika, i te iahiko rānei, mā te huri i te iahiko rerekē (AC) mai i te whatunga hiko, i tētahi atu pūtake hiko rānei ki te iahiko tika. Ko te tohu o te putanga DC ko tōna polarity kore e rerekē - ka rere tonu te iahiko mai i te pito pai ki te pito kino, he mea nui mō ngā ara iahiko hiko tairongo me ngā taputapu tino tika.
Haunga te huringa AC-DC, ko ētahi pūhiko hiko DC ka ahu mai i te pūngao matū (hei tauira, ngā pākahiko) me ngā pūtake hou (hei tauira, te rā).
Ngā Kāwai Matua o ngā Pūnaha Hiko DC
He maha ngā āhua o ngā pūhiko hiko DC i runga i ngā hiahia putanga, te tika o te whakahaere, te pūtake hiko, me te rahi. Kei raro nei ngā momo e whakamahia whānuitia ana:
●Pūtake Hiko Raina
Ka whakamahia e tēnei momo he huringa whakawhiti me te huringa whakatikatika hei whakaheke me te huri i te hiko AC ki te DC, ā, ka whai ake he kaiwhakahaere ngaohiko raina hei whakangawari i te putanga.
● Ngā Painga: He iti te haruru, he iti hoki te ngaru
● Te Herenga: He rahi ake te rahi, he iti ake te whai huatanga ki te whakatauritea ki ngā tauira whakawhiti
● Pai rawa atu mō: Te whakamahinga taiwhanga, ngā ara iahiko anaro
●Whakawhitite mahiPūtake Hiko
Mā te whakawhiti auau-tiketike me ngā wāhanga rokiroki pūngao pērā i ngā inductors, i ngā capacitors rānei, ka whakaratohia e te SMPS he huringa ngaohiko whai hua.
● Ngā Painga: He tino whai hua, he iti te rahi
● Te Herenga: Tērā pea ka puta he EMI (whakararuraru hikohiko)
● Pai rawa atu mō: Te aunoatanga ahumahi, ngā pūnaha LED, ngā whakawhitiwhiti kōrero
●Pūnaha Hiko Whakahaere-Ngaohiko
I hangaia kia mau tonu te ngaohiko putanga ōrite, ahakoa ngā rerekētanga o te mana tāuru, te rerekētanga rānei o te kawenga.
● Ka taea te whakatinana hei pūnaha raina, hei pūnaha whakawhiti rānei
● Pai rawa atu mō: Ngā taputapu e pāngia ana e te kore pumau o te ngaohiko
●Pūnaha Hiko Auaha Pūmau
Ka whakarato i te putanga iahiko pumau, ahakoa ngā panonitanga o te ātete kawenga.
● Pai rawa atu mō: Te taraiwa LED, te whakakikorua hiko, ngā tono utu pākahiko
● Pūnaha Hiko Pūhiko
He pūtake DC kawe, he pūtake motuhake hoki ngā pākahiko, e huri ana i te pūngao matū hei mana hiko.
● Ngā Painga: Te kawe, te motuhake mai i te whatunga
● Pai rawa atu mō: Ngā hikohiko pūkoro, ngā pūnaha hiko tārua
●Pūngao rā ManaTukunga
Ka whakamahi i ngā panera rā hei huri i te hihi o te rā ki te hiko DC. He mea hono tahi me ngā pūmana rokiroki pākahiko me ngā pūmana utu mō te putanga pono.
● Pai rawa atu mō: Ngā tono i waho o te whatunga hiko, ngā pūnaha hiko pumau
Ngā Utauta Whakamātautau: Te Tūranga o ngā Utaina Hiko
Hei whakamana i te mahi a ngā pūhiko hiko DC i raro i ngā āhuatanga kawenga rerekē, ka whakamahia ngā kawenga hiko. Ka āwhina ēnei taputapu ka taea te whakarite i ngā kaihanga me ngā miihini ki te whakatauira i te whakamahinga o te ao tūturu, me te whakarite hoki i te pumau.
Te Kōwhiri i te Pūnaha Hiko DC Tika
Ko te whiriwhiri i te pūtake hiko DC tino pai e whakawhirinaki ana ki:
● Ngā whakaritenga ngaohiko me te iahiko o tō tono
● Te ātete ki te ngaru me te haruru
● Ngā hiahia whai hua me ngā herenga wāhi
● Ngā āhuatanga taiao (pāmahana, haumākū, wātea o te whatunga)
He kaha motuhake tō ia momo pūhiko — ko te mārama ki ēnei rerekētanga te mea nui ki te whakapai ake i te mahi me te pono o tō pūnaha.
