Iyini Imodi Ejwayelekile Ye-Chip | ULULAME

Ngabe kukhona iziqeshana imodi ejwayelekile yokuxhuma yokuklinya uGetwell uzophendula imodi evamile ekugcineni akukho patch;

Sidinga ukuqonda ukuthi isebenza kanjani; Ama-inductors wemodi ejwayelekile anokungena okuphezulu kokuqala, impedance enkulu nokulahleka kokufakwa kunkambu ye-geomagnetic, ukucindezelwa kokuphazanyiswa okuhle, kanye nokulahleka kokufakwa okungafakwanga resonant ebangeni elibanzi lemvamisa.

imodi ejwayelekile yokuminywa ivame kakhulu ekuphileni kwansuku zonke. Ekusetshenzisweni kwamakhompiyutha, kunamasekethe ahlukahlukene aphakeme kakhulu, amasekethe edijithali namasekhethi e-analog axutshwe kubhodi yomama yangaphakathi yekhompyutha. Lapho zisebenza, zikhiqiza inani elikhulu lamagagasi amakhulu kagesi futhi ziphazamisane, okungukuthi i-EMI.Ukuphazanyiswa kwamandla kagesi kuzokhishwa ngaphandle ngokusebenzisa umqhubi noma ikhebula langaphandle kubhodi yomama, kubangele ukungcoliswa kwemisebe kagesi, kungagcini ngokuthinta okujwayelekile ukusebenza kweminye imishini ye-elekthronikhi, kepha futhi kuyingozi emzimbeni womuntu.

Ngabe kukhona iziqeshana zabangenisi bemodi ejwayelekile?

Lokhu kuya ngemodi ejwayelekile eminyene.Iyafana ngesakhiwo nokusebenza kuhlobo oluqondile ngenxa ye-chip evamile yemodi inductor.

imodi ejwayelekile iminyanise amakhoyili aqukethe abaqhubi abazulazula nxazonke kumashubhu wokuvikela, afakwa komunye nomunye. Amashubhu okuvikela angaba yigobongo noma aqukethe i-core yensimbi noma i-magnetic powder core, ebizwa nge-inductance.In L, amayunithi nguHenry (H) no-milliHenry

(mH), uHenry omncane (uH), 1H = 10 ^ 3mH = 10 ^ 6uH.

Ukuhlukaniswa kwama-inductors wemodi ejwayelekile.

Kuhlukaniswe ngefomu le-inductance: i-inductance engaguquki, i-inductance eguquguqukayo.

Kuhlukaniswe ngokwezakhiwo zomqhubi kazibuthe: ikhoyili engenalutho, ikhoyili ye-ferrite, ikhoyili yensimbi, ikhoyili yethusi.

Kuhlukaniswa ngohlobo lomsebenzi: ikhoyili ye-antenna, ikhoyili eguquguqukayo, ikhoyili yokuminyanisa, ikhoyili yomgibe, ikhoyili yokuphambuka.

Kuhlukaniswe ngesakhiwo esigoqayo: ikhoyili yelebuli elilodwa, ikhoyili enezingqimba eziningi, ikhoyili yezinyosi.

Imingcele eyinhloko yesici sekhoyili ye-inductance:

1. Ukwehla kwamandla kagesi L

I-inductance L imele izici ezikhona zekhoyili uqobo, ezimele ngosayizi ojwayelekile wemodi ejwayelekile.Ngaphandle kwamakhoyili akhethekile we-inductance (ama-color code inductors), i-inductance ngokuvamile ayimakiwe kukhokho, kepha yigama elithile.

I-XL engu-2

Usayizi wekhoyili ye-inductance ekuvinjelweni kwamanje kwe-AC kubizwa ngokuthi yi-inductive reactance XL, iyunithi iyi-ohm. Ukuhlobana kwayo ne-inductance L kanye nemvamisa eshintshashintshayo yamanje F ngu-XL = 2πfL

3.Quality isici Q

Isici sekhwalithi Q ubuningi bomzimba obumele ikhwalithi yekhoyili, i-Q isilinganiso sokumelana ne-inductive XL nokumelana kwayo okulingana, okungukuthi: Q = XL / R

Ukuphakama kwenani le-Q lekhoyili, kuncipha ukulahleka kwe-loop Inani le-Q lekhoyili lihlobene nokumelana kocingo kwe-DC, ukulahleka kwe-dielectric kwamathambo, ukulahleka okubangelwe yisihlangu noma umgogodla wensimbi, kanye nomthelela womphumela wesikhumba kumvamisa ophakeme.Ivelu ye-Q yekhoyili imvamisa isukela emashumini iye emakhulwini.

Amandla asatshalalisiwe

I-capacitance phakathi kwekhoyili iyaphenduka futhi ijike, phakathi kwekhoyili nesihlangu, phakathi kwekhoyili ne-plate yaziwa njenge-capacitance esatshalalisiwe.Ubukhona bamandla okusatshalaliswa banciphisa inani le-Q lekhoyili futhi kwenza ukuzinza kube kubi kakhulu. Ngakho-ke, okuncanyana amandla okusatshalaliswa kwekhoyili kuba ngcono.

Ama-coil ajwayelekile ajwayelekile asetshenziswa yilezi:

1.Single ungqimba ikhoyili

Ikhoyili eyodwa yongqimba yenziwa ngocingo lwengcingo oluhlanganisiwe nxazonke kuthubhu lephepha noma ifreyimu ye-bakelite.

2.Ikhoyili yezinyosi

Uma ikhoyili idlulile, izindiza zayo azifani nobuso bokujikeleza, kepha ziwela ku-engela echazwe yi-Yi. Lokhu kubizwa ngokuthi ikhoyili yezinyosi. Futhi inani lezikhathi lapho ucingo luguqa emuva naphambili ngemuva kokuba seluzungeze kanye, kuvamise ukubizwa ngokuthi inani lamaphuzu okugoba. Le ndlela inezinzuzo zevolumu elincane, amandla amancane asatshalaliswa kanye ne-inductance enkulu. umshini wokugaya uju wezinyosi usetshenziselwa ukuvunguza amakhoyili asezinyosini. Lapho amaphuzu asongwayo eba maningi, amandla okusatshalaliswa amancane aba mancane.

Umgogodla we-3.Ferrite ne-iron powder coil

Ukungeniswa kwekhoyili kuhlobene nokuba khona noma ukungabi khona komgogodla.Ukufaka umgogodla we-ferrite kwikhoyili engenalutho kungakhuphula ukungeniswa futhi kuthuthukise izinga lekhwalithi yekhoyili.

Ikhoyili ye-4

Ikhoyili eyinhloko yethusi isetshenziswa kabanzi ebangeni le-wave le-ultrashort. Isikhundla sekhoyili eyinhloko yethusi sijikeleziswa ukushintsha i-inductance, elula futhi eqine.

Ikhodi ye-inductor ye-5.Color

Ikhodi yombala inductor iyi-inductor ene-inductance engaguquki, futhi i-inductance yayo imakwa yindandatho yombala njengokumelana nayo.

Ikhoyili 6.choke (ikhoyili binda)

Ikhoyili evimbela ukugeleza kokushintshana kwamanje ibizwa ngokuthi ikhoyili yokuminyanisa, ehlukaniswe ngekhoyili yokuchama yemvamisa ephezulu kanye nekhoyili yokuphinda imvamisa ephansi.

Ikhoyili ye-7.Deflection

Ikhoyili ye-Deflection ngumthwalo wokukhishwa wesifunda sokuskena se-TV. Ikhoyili yokuphambuka idinga ukuzwela okuphezulu kokuphambuka, insimu kazibuthe efanayo, inani eliphakeme le-Q, usayizi omncane nentengo ephansi.

Okungenhla ulwazi lwe-SMT mode ejwayelekile yokuminyanisa, ngethemba ukukusiza ngandlela thile.Singabahlinzeki be-inductor abavela eChina - Getwell Electronics.Uma ungaqondi, wamukelekile ukuxhumana nathi!
