Izici kanye nezicelo eziyinhloko zezinto ze-ferrite zama-high frequency transformers

Kunezinhlobo ezimbili zama-ferrite cores asetshenziswa ekukhiqizeni ama-high frequency transformers: ama-ferrite cores nama-alloy cores.Ama-ferrite cores ahlukaniswe abe izinhlobo ezintathu: i-manganese zinc, i-nickel zinc kanye ne-magnesium zinc.Ama-alloy cores nawo ahlukaniswe abe yi-silicon steel, iron powder cores, iron-silicon aluminium, iron-nickel full multi, molybdenum PoMo alloy, amorphous, microcrystalline alloy.Namuhla ngabakhiqizi be-transformer yamandla abaqotho be-Xinwang ubuchwepheshe kuwo wonke umuntu incazelo emfushane yama-cores ochungechunge lwe-ferrite oxygen Hugh.

Izinto ze-ferrite ezisetshenziswa kuma-high frequency transformers zonke ziyizinto ezithambile zikamagnetic ferrite.Ngenxa yokumelana okuphezulu kwezinto ezithambile zikazibuthe ze-ferrite, ukulahleka kwemvamisa ephezulu kuncane, kulula ukukhiqizwa ngobuningi, ukungaguquguquki okuhle komkhiqizo, izindleko eziphansi, okwamanje isetshenziswa kakhulu kuma-high frequency transformers a material magnetic.Izinto ezithambile zikazibuthe ze-ferrite zihlukaniswe ikakhulukazi i-Mn-Zn ferrite kanye ne-Ni-Zn ferrite izigaba ezimbili, i-Mn-Zn ferrite yokusebenza imvamisa ku-0.5 ~ 1MHz kuma-high-frequency transformers alandelayo, i-Ni-Zn ferrite yokusebenza imvamisa ku-1MHz noma ngaphezulu. kuma-high-frequency transformers, izinto ze-Mn-Zn kanye ne-Ni-Zn ferrite zinezinhlobonhlobo eziningi, izici zezinto ezibonakalayo nazo zihlukile, ngokulandelanayo ngezidingo ezihlukahlukene ezahlukene kuma-transformers aphezulu kanye nama-inductors.Izindawo eziyinhloko zihlanganisa okulandelayo.

Ama-transformer kagesi okudlulisa amandla, ukuguqulwa kwe-voltage kanye nokuhlukaniswa njll. Kudingeka izinto ezinokufakwa kukazibuthe okugcwala okuphezulu kanye nokulahlekelwa kwamandla aphansi.

Ama-transformer esignali, asetshenziselwa ukudlulisa amasiginali we-AC noma i-pulse ngaphandle kokuhlanekezela, ukufanisa i-impedance, ukuhlukaniswa, njll. Idinga izinto ezikwazi ukungena kalula, ukulahlekelwa kwe-hysteresis okuphansi nokuzwela okuphansi ku-DC.

Ama-inductors okuhlunga okuxhumana ngocingo, adinga ukuzinza okuhle kanye nenani eliphezulu le-Q.Okubalulekile kunokulahlekelwa okuphansi, i-coefficient yezinga lokushisa eliphansi kakhulu ebangeni lokushisa elishiwo kanye nokuzinza okuhle uma kuqhathaniswa nesikhathi.

Izicindezeli zokugxambukela, ezicindezela amasiginali wokuphazamiseka kwemvamisa ephezulu ezingafunwa futhi zidlule kumasignali awusizo efrikhwensi ephezulu.I-impedance ephezulu (ukungena kazibuthe okuphezulu) ebangeni lefrikhwensi ehlanganisiwe iyadingeka.

Ama-inductors amasekhethi okushaya kwenhliziyo abambezelekile, asetshenziselwa ukubambezeleka kwama-pulses.Idinga izinto ezinokungena kazibuthe okuphezulu.

Ama-inductors okugcina amandla kanye namasekhethi ashelelayo.Idinga izinto ezisetshenziswayo ezinamavelu wamandla okungenisa kazibuthe okugcwala okuphezulu.

Ama-circuit inductors ashuniwe anebhendi ethile yokudlula.Idinga izinto ezinokulahlekelwa okufanele kanye nokuzinza okuhle kwezinga lokushisa.

2.2 Izinhlobo zama-ferrite cores zama-high frequency transformers

Ama-Ferrite cores enziwa ngokubunjwa nokucwiliswa, futhi kunezinhlobo eziningi, ikakhulukazi ezimise okwe-E, ezimise okwe-can, ezimise okwe-U nezimise okwendandatho, njll.

Lezi yizici eziyisisekelo kanye nobubanzi bokusetshenziswa kwezinto ze-ferrite
