I-inductor emise okwe-Iiyingxenye yokungeniswa kwe-electromagnetic eyakhiwe uhlaka lwamathambo lukazibuthe olumise okwe-I kanye nocingo lwethusi olunameyili, olungaguqula amasignali kagesi abe amasignali kazibuthe.
I-inductor emise okwe-I ngokwayo iyi-inductor. Isuka kusimo sohlaka lwamathambo , okufana nomoya omise okwe-I, kanye nekhoyili endaweni ethi “I”. Ama-inductors ethu ajwayelekileama-chip inductors, RF inductors,ama-inductors kagesi, ama-inductors emodi evamile, ama-inductors ozibuthe, njll. Namuhla, ngeke sethule lawa ma-inductors. Hlobo luni lwama-inductors? Leyo yi-inductor emise okwe-I
Isithombe esimise okwe-Inductor Core
Njengenye ye-plug-in inductors, i-inductor enesimo se-I ayikona nje kuphela usayizi omncane, kodwa futhi kulula ukuyifaka, okuyi-inductor yohlobo lwe-plug-in futhi ithatha indawo encane; Isici esiphezulu se-Q; I-capacitance esabalalisiwe incane; Imvamisa ye-self resonance ephezulu; Isakhiwo senaliti esikhethekile somhlahlandlela, akulula ukukhiqiza into evaliwe yesifunda.
II-inductor emise okwe-Iisebenzisa i-conductor ukudlulisa i-voltage ye-AC neyamanje. I-inductance emise okuka-I isilinganiso sokuguquguquka kazibuthe kokhondatha kuya kweyamanje ekhiqiza ukugeleza kazibuthe okushintshanayo eduze kwekhondakta lapho umqhubi edlula i-AC yamanje. I-inductor emise okwe-I ivamise ukusetshenziselwa ukufanisa isekethe nokulawula ikhwalithi yesignali, futhi ngokuvamile ixhunywa nokunikezwa kwamandla.
Ukuzinza kwe-inductor emise okwe-I kungaphezulu kwalokho kwe-inductor evamile. Ukudlula kwamanje kumjikelezo kuzinzile, futhi ukusebenza kahle nakho kuthuthukiswa kakhulu. Umsebenzi oyinhloko we-inductor emise okwe-I ukuhlunga amasiginali, umsindo wokuhlunga, ukusimamisa ukuphazanyiswa kwamanje nokulawula ukuphazanyiswa kwe-electromagnetic, okuwukulinganisa okuhle kakhulu kwe-EMI. Namuhla, ngingathanda ukwabelana nawe mayelana nesakhiwo nezici ze-inductor emise okuka-I.
Isakhiwo nokwakheka kwe-inductor emise okwe-I
Uhlaka lwe-inductor emise okwe-I lwakhiwa ukusekelwa okusongayo kwekhoyili ewumgogodla wethusi. I-inductor emise okwe-I ingenye yezakhiwo zesekethe ye-elekthronikhi noma idivayisi, ebhekisela kulokhu: lapho izinguquko zamanje, ezinye izikhombi ezinkulu ezingaguquki noma ama-inductors aguquguqukayo (njengekhoyili e-oscillating, ikhoyili yamanje yokumelana, njll.) izokhiqiza amandla e-electromotive ukumelana. ushintsho lwamanje ngenxa yokungeniswa kwe-electromagnetic.
I-inductor evame ukusetshenziswa emise okwe-I ithathwa njengenguqulo eqondile ye-axial inductor, efana ne-axial inductor kalula ekusetshenzisweni kwayo. Kodwa-ke, i-inductor efana ne-I evame ukusetshenziswa ingaba nohlobo olukhudlwana lwe-inductance, futhi yamanje ingathuthukiswa ngokwemvelo ekusetshenzisweni;
Ezimweni eziningi, ucingo olunamelled (noma ucingo olusongwe ngentambo) lulinyazwa ngokuqondile kuhlaka lwamathambo, bese kuthi umgogodla ozibuthe, umgogodla wethusi, umgogodla wensimbi, njll. ufakwe emgodini ongaphakathi wohlaka lwamathambo ukuze kuthuthukiswe i-inductance yawo.
Uhlaka lwamathambo ngokuvamile lwenziwa ngepulasitiki, i-bakelite kanye ne-ceramics, futhi lungenziwa lube ngamajamo ahlukene ngokwezidingo zangempela. Amakhoyili amancane angenisayo (njengama-inductors amise oku-I) ngokuvamile awasebenzisi uhlaka lwamathambo, kodwa asonge ngokuqondile intambo enoqweqwe oluqinile kumongo kazibuthe.
Umdwebo we-inductor emise okwe-I
Izici ze-inductor emise okwe-I
1. I-inductor encane eqondile, ethatha indawo encane yokufaka;
2. I-Capacitance encane esabalalisiwe kanye nemvamisa ephezulu ye-self resonance;
3. Iphini lomhlahlandlela okhethekile akulula ukubangela isifunda esivulekile.
4. Vikela nge-PVC noma nge-UL umkhono oshwabana wokushisa.
5. Ukuvikelwa kwemvelo kwamahhala okuholayo.
Izici ze-inductor emise okwe-I
1. Ibanga lenani le-inductance: 1.0uH ukuya ku-100000uH.
2. Isilinganiso samanje: ngokusekelwe ekukhuphukeni kwezinga lokushisa, akufanele sidlule i-200C.
3. Izinga lokushisa elisebenzayo: - 20oC kuya ku-80oC.
4. Amandla etheminali: ngaphezu kuka-2.5 kg.
Umsebenzi we-inductor emise okwe-I
1. Ukugcinwa kwamandla nokuhlunga endaweni yamandla kwenza umthombo wokubonisa ugesi uzinze.
2. I-Oscillation, eyenza ingxenye ye-oscillation kusekethe yokushintsha ukuze kukhuliswe i-voltage
3. Ukunqanda ukuphazamiseka nokunqanda ukuphazamiseka: kusebenza njengokuminyanisa ukunikezwa kwamandla kanye ne-inductor yemodi ehlukile ukuvimbela izingxenye ze-harmonic ekunikezeni amandla ekungcoliseni igridi yamandla futhi ziphazamise ukunikezwa kwamandla, ukudlala indima ezinzile.
Imishini eminingi kagesi iqukethe ama-RF inductors. "Ukuze kulandelwe izilwane, ithubhu lengilazi elifakwe esikhumbeni sezilwane zethu ezifuywayo liqukethe i-inductor ngaphakathi," kusho uMaria del Mar Villarrubia, unjiniyela wokucwaninga nokuthuthukiswa wePlummer Company. “Njalo uma imoto iqalwa, kuzobe sekwenziwa ukuxhumana okungenantambo phakathi kwama-inductors amabili, eyodwa ingaphakathi emotweni enye ngaphakathi kokhiye.”
Kodwa-ke, njengoba izingxenye ezinjalo zitholakala yonke indawo, ama-RF inductors nawo anezinhlelo zokusebenza eziqondile kakhulu. Kumjikelezo we-resonant, lezi zakhi zivame ukusetshenziswa ngokuhlanganiswa nama-capacitor ukukhetha imvamisa ethile (njenge-oscillating circuit, i-oscillator elawulwa yi-voltage, njll.).
Ama-RF inductors angasetshenziswa futhi ekufaniseni izinhlelo zokusebenza ukuze kuzuzwe ibhalansi ye-impedance yemigqa yokudlulisa idatha. Lokhu kuyadingeka ukuze kuqinisekiswe ukudluliswa kwedatha okusebenzayo phakathi kwama-IC.
Uma isetshenziswa njenge-RF choke, ama-inductors axhunywa ochungechungeni lwesekethe ukuze asebenze njengezihlungi ze-RF. Ngamafuphi, i-RF choke isihlungi se-low-pass, esizonciphisa amaza aphakeme, kuyilapho amaza aphansi engeke avinjwe.
Liyini inani le-Q?
Uma kuxoxwa ngokusebenza kwe-inductance, inani le-Q liyisilinganiso esibalulekile. Inani elingu-Q liyinkomba yokukala ukusebenza kwe-inductance. Ipharamitha engena-Dimensionless esetshenziselwa ukuqhathanisa imvamisa ye-oscillation nezinga lokulahlekelwa kwamandla.
Lapho inani le-Q liphakeme, ukusebenza kwe-inductor kuseduze kakhulu ne-inductor efanelekile engalahleki. Okusho ukuthi, inokukhetha okungcono kumjikelezo we-resonant.
Enye inzuzo yenani eliphezulu le-Q ukulahlekelwa okuphansi, okungukuthi, amandla amancane asetshenziswa yi-inductor. Inani eliphansi le-Q lizoholela kumkhawulokudonsa obanzi kanye ne-amplitude ephansi ye-resonance eduze naseduze kwe-oscillation frequency.
Inani le-inductance
Ngokungeziwe ku-Q factor, ukukalwa kwangempela kwe-inductor vele kuyivelu yayo ye-inductance. Kuzinhlelo zokusebenza zomsindo namandla, inani le-inductance ngokuvamile ngu-Henry, kuyilapho izinhlelo zokusebenza zemvamisa ephezulu zivame ukudinga i-inductance encane kakhulu, ngokuvamile ebangeni le-millihenry noma i-microhenry.
Inani le-inductance lincike ezicini ezimbalwa, okuhlanganisa ukwakheka, usayizi oyinhloko, i-core material kanye nokuphenduka kwamakhoyili wangempela. I-inductance ingalungiswa noma ilungiswe.
Isicelo seI-Inductor emise okwe-I
I-inductor emise okwe-i ivamise ukusetshenziswa ku-: I-TV nezinto ezilalelwayo; Imishini yokuxhumana; I-Buzzer ne-alamu; Isilawuli samandla; Amasistimu adinga i-broadband namanani aphezulu we-Q.
Ngokuqonda okungenhla kokusebenza, izici kanye nemisebenzi ye-inductor emise okwe-I, singafunda ukuthi i-inductor emise okwe-I isetshenziswa kabanzi ku-GPS egibele imoto, iDVD efakwe emotweni, izinto zokuhlinzeka ngogesi, isiqophi sevidiyo, isibonisi se-LCD, ikhompuyutha. , izinto zasendlini, amathoyizi, imikhiqizo yedijithali, okokusebenza kobuchwepheshe bezokuphepha neminye imikhiqizo kagesi.
Uma unentshisekelo ngemininingwane eyengeziwe, sicela ukhululekeXhumana nathi.
