Njengoba igama lisho, i-high-frequency transformer iyithuluzi lamandla kagesi elishintsha i-voltage.Kuyidivayisi esebenzisa umthetho we-Faraday wokungeniswa kuka-electromagnetic ukushintsha i-voltage ye-AC, ikakhulukazi eyakhiwe ikhoyili eyinhloko, i-ferriteingqikithi, ikhoyili yesibili, njll. Ingabona ukuguqulwa okufanayo kokufakwayo nokuphumayo kwamanje, i-voltage ne-impedance, kanye nokuhlukaniswa ngokomzimba kwezinga lokuqala.Ngokusho kwe-voltage eyinhloko ehlukene, ingahlukaniswa i-step-down high-frequency transformer, i-step-up high-frequency transformer kanye ne-isolation high-frequency transformer.
Imvamisa kagesi esetshenziswa ekuphileni kwethu kwansuku zonke ngu-50Hz, okubizwa ngokuthi i-low-frequency alternating current.Uma i-high-frequency transformer isebenza kule mvamisa, siyibiza ngokuthi i-high-frequency transformer low-frequency high-frequency transformer, ebizwa nangokuthi i-power frequency high-frequency transformer.I-high-frequency transformer inevolumu enkulu nokusebenza kahle okuphansi.I-iron core ipakishwe ngamashidi ensimbi e-silicon avaleleke ngokulinganayo, futhi ikhoyili eyinhloko ilinyazwe ngocingo olungenasici.I-voltage eyinhloko ilingana nokujika kwabo.
Ukwengeza, amanye ama-high-frequency transformers asebenza ezinkulungwaneni zezilungiselelo ze-kilohertz, futhi lesi siguquli se-high-frequency siba i-high-frequency transformer.Ama-high frequency transformers ngokuvamile asebenzisa ama-cores magnetic esikhundleni se-iron cores.I-High frequency transformer inevolumu encane, ukuphenduka okumbalwa kwekhoyili yokuqala nokusebenza kahle okuphezulu.
Imvamisa yokusebenza ye-high-frequency transformer ivamise ukuba amashumi kuya kumakhulu ekhilohertz.I-High frequency transformer isebenzisa umgogodla ozibuthe, futhi ingxenye eyinhloko ye-magnetic core i-zinc ferrite ye-manganese.Le nto ine-eddy yamanje ephansi, ukulahleka okuphansi nokusebenza kahle okuphezulu kumafrikhwensi aphezulu.Imvamisa ephansi yokusebenza kwefrikhwensi ye-high frequency transformer ngu-50Hz.I-high frequency transformer core iwuhlobo lwezinto ezithambile zensimbi kazibuthe.Ishidi lensimbi elincanyana le-silicon linganciphisa kakhulu ukulahlekelwa kwamanje kwe-eddy, kodwa ukulahlekelwa kusekukhulu kunalokho kwe-high-frequency transformer core.
I-high-frequency transformer enamandla afanayo okukhiphayo incane kakhulu kune-low-frequency high-frequency transformer, futhi amandla ayo okushisa aphansi.Ngakho-ke, okwamanje, ama-adaptha amaningi wamandla kagesi wabathengi kanye nemikhiqizo yenethiwekhi ashintsha amandla kagesi, futhi i-transformer yangaphakathi ye-high-frequency iyisici esibaluleke kakhulu sokushintsha amandla kagesi.Umgomo oyisisekelo uwukuguqula okokufaka okushintshanisayo kwamanje kube yi-DC, bese ukuguqulela kumafrikhwensi aphezulu nge-triode noma i-FET.Ngoguquko lwe-high-frequency transformer, okukhiphayo kuyalungiswa futhi, futhi ezinye izingxenye zokulawula zengezwe ukuze kuzinziswe i-voltage DC ephumayo.
Ngamafuphi, ukufana phakathi kwe-high-frequency kanye ne-low-frequency high-frequency transformers kusekelwe kumgomo wokungeniswa kwe-electromagnetic.Umehluko ukuthi imvamisa ephansi kanye nama-high frequency transformers yizinsimbi zensimbi ezenziwe ngamashidi ensimbi ye-silicon, futhi ama-high frequency transformers ayizingcezu eziphelele ezenziwe nge-manganese zinc ferrite nezinye izinto.
