Joalokaha lebitso lena le bolela, transformer e phahameng-frequency ke sesebelisoa sa elektronike se fetolang motlakase.Ke sesebelisoa se sebelisang molao oa Faraday oa induction ea motlakase ho fetola voltage ea AC, haholo-holo e entsoeng ka coil ea mantlha, ferrite.core, coil ea bobeli, joalo-joalo E ka lemoha phetoho e ts'oanang ea ho kenya letsoho le tlhahiso ea hona joale, motlakase le impedance, hammoho le ho itšehla thajana ha boemo ba mantlha.Ho ea ka mefuta e fapaneng ea motlakase oa mantlha, e ka aroloa ka transfoma e theohang holimo-ea maqhubu a phahameng, sefetoleli se phahameng sa maqhubu a phahameng le ho itšehla thajana.
Khafetsa ea motlakase e sebelisoang bophelong ba rona ba letsatsi le letsatsi ke 50Hz, e bitsoang low-frequency alternating current.Haeba motlakase oa maqhubu a phahameng a sebetsa ka nako ena, re e bitsa high-frequency transformer low-frequency high-frequency transformer, eo hape e bitsoang matla a maqhubu a phahameng-frequency transformer.Transformer ea maqhubu a phahameng e na le molumo o moholo le katleho e tlase.Mokotla oa tšepe o kentsoe ka lishiti tsa tšepe tsa silicon tse kentsoeng ka mahlakoreng a mabeli, 'me khoele ea mantlha e entsoe ka terata e nang le enamelled.Motlakase oa mantlha o lekana le linako tsa bona.
Ho phaella moo, li-transformer tse ling tse phahameng li sebetsa libakeng tse ngata tsa kilohertz tse makholo, 'me phetoho ena e phahameng ea maqhubu e fetoha e phahameng-frequency transformer.Li-transformer tse phahameng hangata li sebelisa li-cores tsa makenete ho fapana le li-cores tsa tšepe.High frequency transformer e na le molumo o monyane, likhahla tse fokolang tsa coil ea mantlha le ts'ebetso e phahameng.
Maqhubu a ho sebetsa a high-frequency transformer hangata ke mashome ho isa ho makholo a kilohertz.High frequency transformer e nka matla a khoheli, 'me karolo ea mantlha ea mantlha ke manganese zinc ferrite.Boitsebiso bona bo na le eddy e tlaase hona joale, tahlehelo e tlaase le katleho e phahameng ka maqhubu a phahameng.Maqhubu a tlase a ho sebetsa a transformer e phahameng ke 50Hz.High frequency transformer core ke mofuta oa lisebelisoa tse bonolo tsa tšepe.Letlapa le lesesaane la tšepe la silicon le ka fokotsa tahlehelo ea hona joale ea eddy haholo, empa tahlehelo e ntse e le kholo ho feta ea mantlha ea li-frequency transformer core.
Transformer e nang le maqhubu a phahameng a nang le matla a ts'oanang a tlhahiso e nyane haholo ho feta e fokolang e fokolang, 'me matla a eona a ho futhumatsa a tlaase.Kahoo hajoale, li-adapter tse ngata tsa motlakase tsa lisebelisoa tsa elektronike tsa bareki le lihlahisoa tsa marang-rang li fetola lisebelisoa tsa motlakase, 'me mochine oa motlakase o ka hare ke karolo ea bohlokoa ka ho fetisisa ea ho fetola matla a matla.Molao-motheo oa mantlha ke ho fetolela motlakase o feto-fetohang hore e be DC, ebe o o fetolela maqhubu a phahameng ka triode kapa FET.Ka phetoho ea li-transformer tse phahameng haholo, tlhahiso e lokisoa hape, 'me likarolo tse ling tsa taolo li eketsoa ho tsitsisa motlakase oa DC.
Ka bokhutšoanyane, ho tšoana pakeng tsa li-transformer tse phahameng-frequency le li-frequency tse tlaase li thehiloe holim'a molao-motheo oa motlakase oa motlakase.Phapang ke hore li-frequency tse tlase le tse phahameng ke li-cores tsa tšepe tse entsoeng ka lishiti tsa tšepe tsa silicon, 'me li-transformer tse phahameng ke likotoana tse entsoeng ka ferrite ea manganese zinc le lisebelisoa tse ling.
