Yiziphi izici ezinhlanu ze-inductor | ULULAME

Inxeba lekhoyili libe yisimo esizungelezayo liyashintshashintsha, futhi ikhoyili esetshenziselwa izinjongo zikagesi ibizwa ngokuthi ama- inductors angenye . Ama-inductors asetshenziswa kakhulu kumasekethe e-elekthronikhi, futhi angahlukaniswa abe izigaba ezimbili, enye i-inductors yezinhlelo zesignali, kanti enye i-inductors yamandla wezinhlelo zamandla.

I-Inductor isetshenziswa kabanzi njengengxenye, futhi amanye amapharamitha ayo ayisisekelo azitshwa kalula, okuholela ekwakhiweni okunganele kanye nezinkinga ezinkulu zokusebenzisa umkhiqizo.

Ukuthatha i-inductor yamandla njengesibonelo, imingcele eyisisekelo ye-inductor yethulwa.

inani le-inductance

Ipharamitha eyisisekelo ye-inductance nayo iyipharamitha ebalulekile ethinta impendulo ye-ripple current kanye nomthwalo.

Isimo samanje se-inductor yamandla kusiguquli iwunxantathu wamagagasi amanje. Ngokuvamile, i-ripple current ingasethwa ibe cishe ku-30% womthwalo wamanje. Ngakho-ke, inqobo nje uma izimo zesiguquli zinqunywa, i-inductance efanele ye-inductor yamandla ingabalwa cishe. Ikhethwe ngokwereferensi yevelu yomkhiqizi, uma ufuna ukufaka esikhundleni imodeli entsha ye-inductor, imingcele yayo akufanele ihluke kakhulu kunani eliyireferensi elituswe umphakeli.

saturation current

Isici samanje sokugcwala sibizwa nangokuthi isici se-DC superposition, esithinta inductance esebenzayo lapho i-inductor isebenza. Uma i-inductor ingakhethiwe kahle, i-inductor kulula ukugcwaliswa, okwenza inani langempela le-inductance lehle, alikwazi ukuhlangabezana nezidingo zokuklama, futhi ingase ishise ngisho nesifunda. Incazelo yesekethe egcwele iyahluka kancane, ngokuvamile, ibhekisela okwamanje lapho inductance yokuqala yehliswa ngo-30%.

izinga lokushisa likhuphuka lamanje

Lena ipharamitha ecacisa ibanga elivumelekile lokushisa kwe-ambient uma usebenzisa ama-inductors. Incazelo yokunyuka kwezinga lokushisa yamanje iyahlukahluka kumkhiqizi kuya kumkhiqizi, ngokuvamile, ibhekisela kumjikelezo lapho izinga lokushisa le-inductor likhushulwa ngo-30 ℃. Umphumela wokushisa uyahlukahluka ngendawo yokusebenza yesifunda, ngakho-ke kufanele ikhethwe ngemva kokucabangela indawo yangempela yokusetshenziswa.

DC impedance

Imele inani lokumelana lapho udlula kumanje oqondile. Ithonya elikhulu neliqondile lale parameter ukulahlekelwa kokushisisa, ngakho-ke i-impedance ye-DC encane, ukulahlekelwa okuncane. Kukhona ukungqubuzana okuncane phakathi kokuncishiswa kwe-Rdc kanye nokwenza kancane. Inqobo nje uma kusuka kuma-inductors ashiwo ngenhla ahlangabezana nezici ezidingekayo ezifana ne-inductance kanye nesilinganiso samanje, umkhiqizo one-Rdc encane ungakhethwa.

Isici se-Impedance frequency

I-impedance ye-inductor efanelekile iyanda ngokunyuka kwemvamisa. Kodwa-ke, ngenxa yobukhona be-capacitance ye-parasitic kanye nokumelana ne-parasitic, i-inductor yangempela i-inductive ku-frequency ethile, i-capacitive ngaphesheya kwemvamisa ethile, futhi i-impedance iyancipha ngokunyuka kwemvamisa. Le frequency imvamisa yokujika.

Okungenhla ukwethulwa kwezici ezinhlanu zepharamitha ye-inductor. uma ufuna ukwazi okwengeziwe nge-inductor, sicela ukhululeke ukuxhumana nathi.
