DC (Direct Current) Fetolela ho DC Transformer
DC/DC transformer ke karolo kapa sesebelisoa se fetolelang DC (direct current) ho DC, ka ho khetheha e bua ka karolo e sebelisang DC ho fetolela ho tloha boemong bo bong ba motlakase ho ea boemong bo bong.DC/DC e arotsoe ka mekhahlelo e 'meli ho latela phetoho ea boemo ba motlakase: Transformer e hlahisang motlakase o tlase ho feta ea pele e bitsoa "step-down transformer";Transformer e hlahisang motlakase o phahameng ho feta motlakase oa pele o bitsoa "boost transformer".Hape e ka aroloa ka phepelo ea motlakase e ka thoko le phepelo ea motlakase e sa itšehla thajana e ipapisitseng le kamano ea ho kenya letsoho / sephetho.Mohlala, converter ea DC/DC e hoketsoeng phepelong ea motlakase ea koloi ea DC e fetola DC e nang le matla a phahameng ho ba DC e nang le matla a tlase.'Me likarolo tsa elektroniki tse joalo ka li-IC li na le mefuta e fapaneng ea motlakase oa ts'ebetso, ka hona li hloka ho fetoloa hore e be li-voltage tse tsamaellanang.
Haholo-holo, e bua ka ho fetolela input DC hore e be AC ka Self-oscillation circuit, ebe e fetolela ho DC ka mor'a ho fetola motlakase ka transformer, kapa ho fetola AC hore e be matla a phahameng a DC ka potoloho ea motlakase e imenneng habeli.
Melemo e qaqileng e bontšitsoe ka tlase:
(1) Leakage inductance e ka laoloa ka hare ho 1% -10% ea inductance e ka sehloohong;
(2) Magnetic core e na le khokahano e ntle ea motlakase, sebopeho se bonolo le katleho e phahameng ea tlhahiso;
(3) Maqhubu a phahameng a ho sebetsa, matla a phahameng a matla, maqhubu a pakeng tsa hoo e ka bang 50kHz ~ 300kHz.
(4) Litšobotsi tse ntle tsa ho senya mocheso, tse nang le sebaka se phahameng ho ea ho tekanyo ea molumo, mocha o mokhutšoanyane haholo oa mocheso, o loketseng ho senya mocheso.
(5) Ho sebetsa hantle haholo, sebopeho sa mantlha sa makenete sa sebopeho se khethehileng sa geometri se ka fokotsa tahlehelo ea mantlha ka nepo.
(6) Tšitiso e nyenyane ea mahlaseli a motlakase.Ho lahleheloa ke matla a tlase, ho phahama ha mocheso o tlase, ho sebetsa hantle haholo.
1. E na le induction e phahameng ea matla a khoheli;
2. Mocheso o phahameng oa Curie, tahlehelo e tlaase ea tšepe le ho qobella;
3. Ho senya mocheso o motle, lerata le tlaase le bokhoni bo phahameng;
4. Ha e kenelle metsi, e thibela mongobo, e thibela lerole le ho thothomela;
5. Matla a phahameng a matla;
6. Ho nepahala ho phahameng ha ho lutla ha inductance;
7. Ho tšepahala ho phahameng, botsitso bo phahameng, ho tsitsisa ho phahameng;
Boto ea motlakase ea koloi le seva.
