Iyini ingxenye ye-inductor elungisekayo?Abakhiqizi bokufaka i-plug-in bethula kuwe.

Izingxenye ze-inductor eziguquguqukayo ezivame ukusetshenziswa amakhoyili e-oscillation asetshenziswa kumarediyo we-semiconductor, namakhoyili e-oscillation olayini asetshenziswa kumathelevishini.

Amakhoyili alayini, amakhoyili we-intermediate frequency trap, amakhoyili esinxephezelo sefrikhwensi yomsindo, amakhoyili okuklinywa, njll. abakhiqizi bezingxenye ze-inductance

1. Ikhoyili ye-oscillator esetshenziswa kurediyo ye-semiconductor: Le khoyili ye-oscillator isetshenziswa kumsakazo we-semiconductor ukwenza isekethe ye-oscillator yasendaweni enama-variable capacitor, njll., esetshenziselwa ukukhiqiza i-oscillation yendawo engu-465kHz ephakeme kunesiginali yomsakazo eyamukelwe 器Signal.Faka isekethe yokushuna.Ingaphandle iwungqimba oluvikela insimbi, kanti ingaphakathi lakhiwe ngolwelwesi lwenayiloni, ingqikithi kazibuthe emise okwe-I, ikepisi kazibuthe nesihlalo sephini.Kusetshenziswa intambo enoqweqwe oluqinile olunamandla aphezulu kumongo ozibuthe wohlobo lwe-I.Isivalo sikazibuthe sifakwe kubakaki benayiloni ngaphakathi kwesendlalelo esivikelayo, futhi singazungeziswa phezulu naphansi ukuze kushintshwe indlela yokufaka ikhoyili ngokushintsha ibanga phakathi kwayo nekhoyili.Isakhiwo sangaphakathi sekhoyili yesicupho se-TV siyefana naleso sekhoyili enyakazayo, ngaphandle kokuthi ikhava kazibuthe ingumongo kazibuthe olungisekayo.

2. Ikhoyili ezungezayo yolayini yesethi ye-TV: Ikhoyili e-oscillating yolayini isetshenziswa kumasethi ama-TV asekuqaleni amnyama namhlophe.Yakha isifunda se-oscillator esizithokozisayo (i-oscillator enamaphuzu amathathu noma i-oscillator evimbayo, i-multivibrator) enama-peripheral resistors nama-capacitor kanye nama-transistors oscillation womugqa, asetshenziselwa ukukhiqiza isignali ye-pulse voltage engunxande nge-frequency ye-15625HZ.

Imbobo eyisikwele, faka ikhoyili ephakathi nendawo yeknobhu yokulungisa yokuvumelanisa ngqo embotsheni yesikwele.Ibhangqa elisontekile lokulungiswa kokuvumelanisa iknob lingashintsha ibanga elihlobene phakathi kukamongo nekhoyili, ngaleyo ndlela iguqule ikhoyili ye-inductance, igcine i-oscillation frequency yolayini iku-15625 Hz kanye ne-othomathikhi I-Frequency control (AFC) i-oscillates ngokuhambisana ne-pulse yokuvumelanisa engena. umugqa wesifunda.

3. Ikhoyili ewumugqa womugqa: Ikhoyili ewumugqa womugqa uwuhlobo lwekhoyili yekhoyili ye-magnetic saturation engaqondile (i-inductance yayo iyancipha ngokunyuka kwamandla amanje), ngokuvamile ixhunywa ngochungechunge kuluphu yekhoyili yokuchezuka kolayini, futhi isebenzisa izici zayo zokugcwaliswa kazibuthe. ukunxephezela ukuhlanekezelwa komugqa wesithombe.

Ikhoyili ewumugqa yenziwe ngenxeba lentambo enoqweqwe oluqinile kumongo kazibuthe omise okwe-"I" -i-ferrite ephakeme noma induku kazibuthe ye-ferrite, futhi kufakwe uzibuthe olungisekayo eduze kwekhoyili.Ngokushintsha isikhundla esihlobene sikazibuthe kanye nekhoyili ukushintsha usayizi wekhoyili inductance, ukuze kufezwe injongo yesinxephezelo esiwumugqa.
