Hoa hlokahala ho fetola li-transformer ha u fetola lisebelisoa tsa motlakase.Joale switching transformer ke eng?Melao-motheo ea ts'ebetso le mesebetsi ea li-switching transformer ke life?Ha re li utloisise.
·Selelekela
Phetoho ea phetoho e bua ka transformer e sebelisoang phepelong ea motlakase.E sebetsa ho pulse state ka makhetlo a leshome ho isa ho mashome a kilohertz kapa esita le makholo a kilohertz.Mokotla oa tšepe hangata o entsoe ka thepa ea ferrite.
·Mokhoa o sebetsang oa ho fetola li-transformer
Transformer ke sesebelisoa sa electrostatic se entsoeng ka molao-motheo oa ho kenella ka motlakase.Ha coil e ka sehloohong ea transformer e hokahane le mohloli oa matla a AC, mokokotlo oa tšepe o hlahisa phallo e fapaneng ea makenete.Motlakase oa ho fetola matla o laoloa ke potoloho, 'me mochine oa ho fetola o fetoha ka lebelo le phahameng.
Ho fetola hona joale ka ho toba ho ea ho maqhubu a phahameng a ho fapanyetsana hona joale ho fanoa ho transformer bakeng sa phetoho, ka tsela eo ho hlahisa lihlopha tse le 'ngoe kapa ho feta tsa voltages.Kaha katleho ea maqhubu a phahameng a AC ka potoloho ea transformer e phahame haholo ho feta 50Hz, li-switching tsohle li ka etsoa tse nyenyane haholo, kahoo li fokotsa litšenyehelo.
·To phetha karolo ea ho fetola li-transformer
Mesebetsi e ka sehloohong ea ho fetola li-transformer ke ho fetisetsa matla, ho fetola motlakase le ho kenya letsoho.
Melemo ea eona e ka sehloohong ke boholo bo fokolang, ts'ebetso e phahameng, le ho otlolla ho theko e tlaase.Joalo ka karolo e kholo e bonolo ea makenete ea motlakase, li-switching transformer li sebelisoa haholo ho fetoleng mahlale a phepelo ea motlakase le mahlale a motlakase oa motlakase, hape li sebelisoa lipotolohong tsa maqhubu a phahameng joalo ka phepelo ea motlakase.
Ho ea ka matla a phetisetso ea mochine oa ho fetola, li-transformer tsa matla li ka aroloa ka lihlopha tse 'maloa: 10kVA ke matla a phahameng, 10kVA ~ 0.5kVA ke matla a mahareng, 0.5kVA ~ 25VA ke matla a tlaase,' me ka tlase ho 25VA ke matla a manyenyane.Matla a fapaneng a phetisetso, moralo oa motlakase oa motlakase le ona o fapane.The ferrite core le magnetic saturation coefficient ea transformer ea matla ha e ntle joaloka ea silicon sheet sheet, e bakang matla a manyane haholo ho Hertz ea phetisetso ea matla a AC.Empa o sebetsa ka potoloho ea maqhubu a phahameng, 'me maqhubu a phapanyetsano ea matla ka nako ea nako ea yuniti a phahame haholo (makhetlo a 1000 ho feta a transformer e tlaase-frequency).Ha e kopane, katleho ea eona e ka fihla makhetlo a mangata ho feta ea li-frequency tse fokolang.
·Mosebetsi o mong oa switching transformer ke hore o na le phepelo ea maikutlo
Phello ea maikutlo e fana ka pontšo e ntle ea maikutlo ho PWM IC, e etsa hore e hlahise oscillation e phahameng-frequency hammoho le maqhubu a bobeli, e le hore DC e kenang moeeng o ka sehloohong oa transformer e na le karolo e kholo ea AC, le maqhubu a phahameng a AC. karolo e arotsoe ke motsoako oa transformer, ho theha Pure high-frequency AC ea bobeli, e lokisoang le ho tlhotloa ho fana ka lisebelisoa tsa motlakase.Feedback winding e ka fetola motlakase o tsoang ho boleng bo tsitsitseng.Ho akaretsa, switching transformer e bapala karolo ea phetisetso ea matla, phetoho ea motlakase le ho kenya letsoho.
