He supply transformerless kaha: whakaaro, ngā, te parau tumu o te mahi o te taputapu

hāngai kai Power mō rorohiko whaiaro e i runga i iahiko transformerless hono ki te whatunga (i roto i te meka, reira supply mana pākau i). E āhuatanga ratou e te uara nui o te pai, ngā āhuatanga iti, me te taimaha iti. Heoi, kua he nui drawback te supply transformerless mana - titaha haruru e whai he pānga tōraro i runga i ētahi atu kaupapa RW me ētahi atu pūrere hikohiko kiritaki. Na reira, hua taua ia haere whakamātautau nui mō te hototahi hiko ki ētahi atu taputapu. I tua atu, i te hiko iti kōwae mana supply he motuhake hiko i roto i te wahi o te ara iahiko hiko i te ngaohiko mains. Tenei, i roto i te tahuri, titau te whakamahi o mehua haumaru motuhake i roto i te hanga o taua tuhinga.

Transformerless supply mana: te wahi matua mahi

Kei te taputapu o te wāhanga e whai ake nei:

- he rectifier whatunga;

- tātari EMC;

- keu taiawhio;

- tātari capacitive;

- ngaohiko converter hāngai ana i runga i he pini mana inverter;

- iahiko whakaputa he ngaohiko whakaputa;

- te ara iahiko mana;

- hanga me te whakawhitihia taiawhio o nga tohu urupare ki te ara iahiko mana.

huānga atu

Tei runga i te tauira me te taumahinga, ka taea e te hiko iti supply mana ngā iahiko atu pērā i te regulator rārangi i roto i te puka motuhake ngātahi ranei, tāuru tiaki kikī me putanga ngaohiko me te nāianei, me te pehanga ara iahiko. I tua atu, i roto i taua supply mana kia ngā circuitry mō te whakaputa tohu mana motuhake e whakarato ōrite o te pūrere ki te ara iahiko whāngai.

parau tumu o te mahi

Whakawhiti kai mana ao mo te faafariuraa ngaohiko DC whakamana te ngaohiko tāuru, takitoru. Tuatahi, kua whakatikaina reira, ka mānia. Ko te hua kei te DC ngaohiko, i muri i nei i hanga a tapawhā ngātere i te tere o tekau o kilohertz. I muri iho, ae whakaputaia ketia ana nga ngātere ki te taha ki tuarua ki te whakarea hāngai, me ano haere whakatikatikaina, me te whakaene. Ko te ariki kōpuku pūtahuri transformerless supply mana ngaohiko matua, a rawa wae ratou kaha (te kaha-tiketike atamira putanga). Ka taea te wehea ēnei wāhanga ki kotahi-mutu, me te pana-kume.

kai mana whakarite

Hei whakatika i te uara ngaohiko whakaputa i roto i ngā pūrere transformerless tino whakamahia nuitia tikanga o whanui pini puoro, i te mea te huringa i roto i te he pini roanga, me tatari therebetween. A, no te tenei auau panoni tonu tonu. Ko te hononga i waenganui i enei rahinga rite te roanga o te pini me okioki, tei runga i te ngaohiko whakaputa. Kei te puta ke aunoa reira ki te mau tonu i te ngaohiko whakaputa i roto i te uara mata.
