Thermosetting plastic iphakeji ikhoyili electromagnetic QVT306

Yiziphi izici zepharamitha ye-inductance?

1. Ikhwalithi yesici sekhwalithi:

Isici sekhwalithi Q isici esisetshenziselwa ukukala ubudlelwano phakathi kwamandla agcinwe izinto zokugcina amandla (ama-inductors noma ama-capacitor) kanye nokusebenzisa kwawo amandla, achazwa ngokuthi: Q=2π umkhawulo wamandla agciniwe/ukulahlekelwa kwamandla kwamasonto onke.Ngokuvamile, inani elikhulu le-Q lekhoyili ye-inductance, lingcono, kodwa libe likhulu kakhulu lizokwenza ukuzinza kwesifunda esisebenzayo kubi nakakhulu.

2, I-Inductance:

Lapho i-current in ikhoyili ishintsha, ukuguquguquka kazibuthe okudlula ku-loop yekhoyili ngokwayo okubangelwa amandla ashintshile nakho kuyashintsha, okubangela ikhoyili ngokwayo ukuthi idonse amandla e-electromotive.I-self-inductance coefficient inani elibonakalayo elimelela ikhono lokuzithutha lekhoyili.Kubuye kubizwe nge-self-inductance noma inductance.Ivezwa uL. Ethatha uHenry (H) njengeyunithi, ingxenye eyinkulungwane yayo ibizwa ngokuthi millihenh (mH), ingxenye eyisigidi ibizwa ngokuthi millihenh (H), futhi ingxenye eyinkulungwane yayo ibizwa ngokuthi iNahen (NH).

3. I-DC Resistance(DCR):

Ekuhlelweni kwe-inductance, okuncane ukumelana kwe-DC, kungcono.Iyunithi yokulinganisa ingu-ohm, ngokuvamile ephawulwa ngenani layo eliphezulu.

4, imvamisa ye-Self-resonant:

I-Inductor ayiyona into e-inductive kuphela, kodwa futhi inesisindo somthamo esabalalisiwe.I-resonance kufrikhwensi ethile ebangelwa i-inductance engokwemvelo namandla asabalalisiwe e-inductor ngokwayo ibizwa ngokuthi i-self-harmonic frequency, eyaziwa nangokuthi i-resonance frequency.Ivezwe nge-SRF, iyunithi yi-megahertz (MHz).

5. Inani le-impedance:

Inani le-impedance le-inductor libhekisela enanini lakho konke ukuphazamiseka kwayo ngaphansi kwamanje (inombolo eyinkimbinkimbi), okuhlanganisa ukuxhumana nezingxenye ze-DC.Inani le-impedance lengxenye ye-DC liwukumelana kwe-DC kuphela kokusonga (ingxenye yangempela), futhi inani lokuvinjelwa kwengxenye yokuxhumana lihlanganisa ukusabela (ingxenye ecatshangelwayo) ye-inductor.Ngalo mqondo, i-inductor ingabuye ithathwe ngokuthi "i-resistor yokuxhumana".6. Isilinganiso samanje: Ukuqina kwamanje kwe-DC okuqhubekayo okungadlula ku-inductor kuvunyelwe.Ukuqina kwamanje kwe-DC kusekelwe ekukhuphukeni okuphezulu kwezinga lokushisa kwe-inductor ezingeni lokushisa eliphakeme elingeziwe le-ambient.I-current eyengeziwe ihlobene nekhono le-inductor lokunciphisa ukulahleka kokusonta ngokumelana ne-DC okuphansi, futhi ihlobene nekhono le-inductor lokuhlakaza ukulahleka kwamandla asongayo.Ngakho-ke, i-current eyengeziwe ingathuthukiswa ngokunciphisa ukumelana ne-DC noma ukwandisa isikali se-inductance.Kumagagasi amanje anefrikhwensi ephansi, impande yawo isho inani lamanje eliyisikwele
