Li-transformer tsa elektronike li bapala karolo ea bohlokoa lisebelisoa tsa sejoale-joale tsa elektroniki. Ho ea ka maqhubu a sebetsang, li-transformer tsa elektronike li ka aroloa ka li-transformer tse tlaase-frequency, li-medium-frequency transformer le li-high-frequency transformer. Karolo e 'ngoe le e' ngoe ea maqhubu a li-transformer e na le litlhoko tsa eona tse ikhethileng molemong oa moralo le ts'ebetso ea tlhahiso, 'me e' ngoe ea lintlha tsa bohlokoa ka ho fetesisa ke thepa ea mantlha. Sengoliloeng sena se tla tšohla ka botlalo karohano ea khafetsa ea li-transformer tsa elektroniki le lisebelisoa tsa tsona tsa mantlha.

Li-transformer tse fokolang maqhubu

Li-transformer tsa maqhubu a tlase li sebelisoa haholo ho lisebelisoa tsa elektroniki tse nang le maqhubu a tlase, hangata li sebetsa maemong a 50 Hz ho isa ho 60 Hz. Li-transformer tsena li sebelisoa haholo lits'ebetsong tsa phetisetso le phetiso ea matla, joalo ka li-transformer tsa motlakase le li-transformer tsa ho itšehla thajana. Mokotla oa motlakase o fokolang hangata o entsoe ka lishiti tsa tšepe tsa silicon, tse tsejoang hape e le lishiti tsa tšepe tsa silicon.

Silicon Steel Sheetske mofuta oa thepa e bonolo ea makenete e nang le silicon e phahameng, e fanang ka matla a matla a khoheli le tahlehelo e tlase ea tšepe. Lits'ebetsong tse fokolang, tšebeliso ea lishiti tsa tšepe ea silicon e fokotsa ka katleho tahlehelo ea li-transformer le ho ntlafatsa katleho. Ho feta moo, lishiti tsa tšepe tsa silicon li na le matla a matle a mochini le ho hanyetsa kutu, ho netefatsa botsitso le ts'epahalo ea li-transformer ka ts'ebetso ea nako e telele.

Li-Frequency Transformers tse bohareng

Li-transformer tsa Mid-frequency hangata li sebetsa ho mefuta e mengata ea li-kilohertz (kHz) 'me li sebelisoa haholo lisebelisoa tsa puisano, li-module tsa matla, le lits'ebetso tse ling tsa taolo ea indasteri. Li-cores tsa li-mid-frequency transformers hangata li entsoe ka thepa ea amorphous magnetic.

Lisebelisoa tsa Magnetic tsa Amorphouske li-alloys tse hlahisoang ka mokhoa o potlakileng oa ho pholisa, o hlahisang sebopeho sa amorphous athomo. Melemo ea mantlha ea thepa ena e kenyelletsa tahlehelo ea tšepe e tlase haholo le matla a matla a makenete, a fanang ka ts'ebetso e ntle haholo lipakeng tsa maqhubu a mahareng. Tšebeliso ea lisebelisoa tsa amorphous magnetic ka katleho e fokotsa tahlehelo ea matla ho li-transformer le ho ntlafatsa katleho ea phetoho, e leng se etsang hore e be tse loketseng ka ho khetheha bakeng sa likopo tse hlokang ts'ebetso e phahameng le tahlehelo e tlaase.

Li-transformer tsa maqhubu a phahameng

Li-transformer tsa maqhubu a phahameng hangata li sebetsa ka maqhubu a megahertz (MHz) kapa holimo 'me li sebelisoa haholo ho fetola lisebelisoa tsa motlakase, lisebelisoa tsa puisano tsa maqhubu a phahameng, le lisebelisoa tsa ho futhumatsa tse phahameng. Li-cores tsa li-transformer tse phahameng hangata li entsoe ka thepa ea ferrite ea PC40.

PC40 Ferriteke sesebelisoa se tloaelehileng sa mantlha se nang le matla a matla a khoheli le tahlehelo e tlase ea hysteresis, se fanang ka ts'ebetso e ntle haholo lits'ebetsong tsa maqhubu a holimo. Tšobotsi e 'ngoe ea bohlokoa ea thepa ea ferrite ke matla a bona a matla a ho hanyetsa motlakase, a fokotsang ka katleho tahlehelo ea hona joale ea eddy bohareng, kahoo e ntlafatsa katleho ea transformer. Ts'ebetso e phahameng ea PC40 ferrite e etsa hore e be khetho e nepahetseng bakeng sa li-transformer tsa maqhubu a phahameng, ho fihlela litlhoko tsa ts'ebetso e phahameng le tahlehelo e tlase lits'ebetsong tse phahameng haholo.

Qetello

Karohano ea khafetsa ea li-transformer tsa elektroniki le khetho ea lisebelisoa tsa mantlha ke lintlha tsa bohlokoa tse susumetsang ts'ebetso ea tsona le mefuta ea ts'ebeliso. Li-transformer tsa maqhubu a tlase li itšetleha ka matla a matla a matla a khoheli le thepa ea mochini ea lishiti tsa tšepe tsa silicon, li-transformer tsa maqhubu a mahareng li sebelisa litšobotsi tse tlase tsa tahlehelo ea lisebelisoa tsa amorphous magnetic, ha li-transformer tsa maqhubu a phahameng li itšetlehile ka matla a matla a khoheli le tahlehelo e tlase ea PC40. ferrite. Likhetho tsena tsa thepa li netefatsa ts'ebetso e nepahetseng ea li-transformer ho pholletsa le mefuta e fapaneng ea maqhubu 'me li fana ka motheo o tiileng oa ho ts'epahala le ts'ebetso ea lisebelisoa tsa sejoale-joale tsa elektroniki.

Ka ho utloisisa le ho tseba tsebo ena hantle, baenjiniere ba ka rala le ho ntlafatsa li-transformer tsa elektroniki ho fihlela litlhoko tsa maemo a fapaneng a ts'ebeliso, ba ts'ehetsa tsoelo-pele e tsoelang pele le nts'etsopele ea lisebelisoa tsa elektroniki.
