Ukuqala ukujonga kwi-high frequency transformers, intshayelelo kumgaqo we-transformer

1, Intshayelelo kumgaqo wenguqu

Isiguquli njengoko igama lisitsho, tshintsha amandla ombane wesixhobo sombane sombane.Kukusetyenziswa komgaqo weFaraday we-electromagnetic induction ukuguqula isixhobo sombane we-AC, ikakhulu ngekhoyili ephambili, undoqo wentsimbi, ikhoyili yesibini kunye nezinye izinto.Iyakwazi ukufezekisa igalelo kunye nemveliso yangoku, i-voltage kunye ne-impedance ehambelana nokuguqulwa, njl.Ngokwe-voltage eyahlukileyo yenqanaba lokuqala, inokwahlulwa ibe yi-transformer-down-down, i-step-up transformer, i-transformer yodwa, njl.

2, Ngokwe-frequency yokusebenza eyahlukeneyo, yahlulwe yaba yi-low frequency transformer kunye ne-high frequency transformer.

Ukuphindaphinda kombane wethu wokuvelisa ubomi bemihla ngemihla yi-50 Hz, sibiza le AC amandla aphantsi frequency AC amandla.Ukuba i-transformer isebenza ngokuphindaphindiweyo, senza le transformer ibe yi-low-frequency transformer, ebizwa ngokuba yi-industrial frequency transformer.Olu hlobo lwe-transformer lukhulu kwaye lungasebenzi kakuhle, undoqo wenziwa ngokupakisha amacwecwe ensimbi ye-silicon akhuselwe omnye komnye, iikhoyili eziziiprayimari nezizisekondari zonakaliswa ngocingo olunamelled kunye nenqanaba lokuqala lombane lilingana nenani labo lokujika.

Ukongeza koku, ezinye ii-transformers zisebenza kumashumi eesethingi ze-kilohertz ezingamakhulu aliqela, kwaye ezo ziguquli ziba ngabaguquli bama frequency aphezulu.Iziguquli zefrikhwensi eziphakamileyo azisebenzisi intsimbi engundoqo, kodwa ingundoqo kazibuthe.I-high-frequency transformers i-compact, kunye nenani elincinci lokujika kweekhoyili eziphambili kunye nesekondari kunye nokusebenza okuphezulu.

3, Umahluko ophakamileyo kunye ophantsi we-transformer kunye noqhagamshelwano.

I-high frequency transformer operating frequency iqhele kumashumi e-kilohertz ukuya kumakhulu ekhilohertz, i-transformer isebenzisa i-core magnetic, icandelo eliphambili le-zinc ferrite ye-manganese, le nto i-eddy yangoku incinci, ilahleko ephantsi, ukusebenza kakuhle okuphezulu. .I-low frequency transformer esebenzayo yasekhaya ye-50 Hz, i-transformer core yintsimbi ethambileyo yemagnethi, iphepha elincinci le-silicon yensimbi inokunciphisa kakhulu ilahleko ye-eddy yangoku, kodwa kunelahleko ephezulu ye-transformer core isenkulu.

Imveliso yamandla emveliso efanayo, i-high-frequency transformer kune-low-frequency transformer volume incinci kakhulu, isizukulwana esiphantsi sobushushu.Ke ngoko, uninzi lwabasebenzisi be-elektroniki bangoku kunye neemveliso zenethiwekhi yeadaptha yamandla, zitshintsha unikezelo lwamandla, i-transformer yangaphakathi ye-high-frequency yeyona nto ibalulekileyo yonikezelo lombane lokutshintsha.Umgaqo osisiseko kukuqala ukuguqula igalelo le-AC libe yi-DC kwaye emva koko nge-transistor okanye ityhubhu ye-field-effect ibe yi-high-frequency ngokusebenzisa i-voltage ye-frequency transformer voltage, emva kokulungiswa kwakhona imveliso, kunye nezinye iindawo zokulawula, imveliso ezinzileyo ye-DC voltage.

Ngamafutshane, iziguquli eziphezulu kunye nezisezantsi ziyafana ekusebenziseni umgaqo wokufakelwa kwe-electromagnetic, umahluko kwi-low frequency transformer yintsimbi ye-silicon efakwe kumbindi wesinyithi, i-high frequency transformer yi-zinc ferrite ye-manganese kunye nezinye izinto ezifakwe kwi-butt. ibloko yonke.
