DC DC mai canzawa

Wannan labarin za a sadaukar da shi ga wani sabon kayan aikin lantarki don ƙarawa a jerin. Na'urar da zaka iya hadawa da allunan ci gaba, kamar su Arduino. Hakanan, idan kuna buƙatar ƙarin sani game da menene DC DC mai canzawa, Anan zaku iya koyon kowane abu mai mahimmanci game da wannan da'irar, daga menene, zuwa yadda yake aiki da aikace-aikacen sa.

Kamar yadda kake gani, na'urar da baya canzawa daga wani nau'in na yanzu zuwa wani, kamar yadda wutar lantarki, kuma wannan na iya zama kamanceceniya da wasu abubuwa masu sarrafa wutar lantarki, tunda zai canza daidai wannan girman ...

Menene mai canza DC DC?

DC DC mai canzawa

Un Mai canza DC-DC Nau'in mai canzawa ne wanda zai canza daga madaidaicin halin yanzu zuwa wani kai tsaye, amma tare da matakan ƙarfin lantarki daban. Wato, baya canzawa tsakanin nau'ikan na yanzu, kawai yana canza matakin ƙarfin lantarki ne. Kari kan haka, suna da shahararrun da'irori a cikin kayan lantarki (mutum-mutumi, drones, kayan wuta, motocin lantarki, caja, ...).

Wadannan masu canza DC DC za su adana kuzarin wancan yana shiga cikin sito na wucin gadi sannan kuma zasu isar dashi zuwa wata mashiga ta wani wutan lantarki daban. Don hakan ta yiwu, dole ne ayi amfani da ma'ajiyar filin maganadisu kamar inductors ko ajiyar filin lantarki kamar ƙarfin wuta. Yayin aiwatar da sauyawa, ana amfani da transistors, diodes, da dai sauransu.

Misali, zai iya zama gama gari a samu Masu sauya DC DC Buck, tare da LM2596 wanda zai iya samun shigarwar kwatankwacin 4.5v zuwa 40v DC kuma ya fitar da 1.23 zuwa 37v DC.

Wasu masu canza DC DC suna ba da izinin sauya makamashi bayarwaDon wannan, ana maye gurbin diodes na masu canza al'ada ta hanyar transistors masu sarrafa kansu. Ana amfani da wannan nau'in nau'in jujjuyawar don wasu tsarin kamar birki na abin hawa ko KERS.

Amma ga format, za ka same su a cikin hanyar jigilar hanyoyinKari kan haka, za su iya zuwa ta sigar kayan aiki, tare da kara wasu abubuwan don kara musu aiki da kuma cewa za a iya amfani da su a hanya mafi sauki.

Nau'in masu canzawa

Akwai daban-daban nau'ikan masu canza DC DC, ya danganta da abubuwan da yake dasu. Mafi mahimmanci sune:

  • SAURARA: shine mafi sauki kuma yawanci shine yafi kowa. Tana da hanyar shigarwa da fitarwa tare, saboda haka, ba ta da fitowar da aka keɓance daga shigarwar. Voltagearfin fitarwa zai zama ƙasa, kuma na daidaita daidai kamar na shigarwar.
  • Lif (Boost) : a cikin wannan nau'in nau'in mai canza DC DC, ƙarfin fitarwa koyaushe yana sama da ƙarfin shigarwa. Wato, ƙara ƙarfin lantarki maimakon rage shi. Ba a keɓance fitarwa daga shigarwar ba, tunda suna da ƙasa tare. Matsalar ita ce ba za ku iya iyakance fitowar ta yanzu ta hanyar lantarki ba.
  • Baya ko baya (Flyback): ƙarfin fitarwa zai iya zama ƙasa da ƙasa sama da ƙarfin ƙarfin shigarwa, amma tare da juyawa polarity. Nau'in mai canzawa yana iya samun shigarwar fitarwa na fitarwa ko a'a. A cikin waɗanda aka keɓe, ana yin ta ta hanyar mai canza wuta.
  • Kai tsaye (Gaba): yana aiki iri ɗaya kamar Buck, amma yana da mai canza wuta wanda ke aiki azaman rufi tsakanin shigarwa da fitarwa, yana iya samun sakamako da yawa kuma tare da ƙarfin wuta sama da shigarwar, gwargwadon winding na biyu.
  • Turawa (Turawa).
  • Gada.
  • Rabin-Bridge: sauƙaƙawa ne na mai canza gada ta DC DC, yana da transistors guda biyu da ƙarfin wuta biyu a cikin firamare.
