Ikoranabuhanga n'Ubwiza ku Inductor Integrated - igice cya 2

Imbaraga ZikozweAbakora imyitozo ngororamubiri, hamwe n'amakuru agezweho mu ikoranabuhanga ry'inganda hamwe n'ingingo zo kugenzura ubuziranenge, iyi nyandiko ikubiyemo ibintu bitandukanye kuva ku mahame shingiro, inzira z'ibikoresho kugeza ku guhitamo nyakuri no kwirinda ingorane, gufata amahitamo meza mu gushushanya amashanyarazi. Reka dukomeze ikiganiro cyo mu nkuru ibanziriza iyi (ubushize twaganiriye ku bibazo 6)

7. "Kunanirwa guhangana n'umuvuduko" ni iki? (Ikibazo gikomeye mu guhitamo!)

Iyi ni "icyuho cyihishe" cyoroshye kwirengagizwa. Hari urwego rukingira hagati y'ifu y'icyuma imbere mu gice cy'icyuma gikozwemo.inductor.
* Ikibazo: Mu gihe kirekire imikorere yayo ikoresha ingufu nyinshi, iyo imbaraga zo gukingira zidahagije, urwego rwo gukingira hagati y’ingufu z’icyuma rushobora gutoborwa.
* Ingaruka: Bingana no guhuza resistor mu buryo buteganye n'uburyo bunyura hagatiinductor, bigatera kwiyongera gukabije kw'igihombo mu gice cy'imbere cy'umubiri, ubushyuhe bukabije, ndetse no gutwika ibice by'umubiri.
*Irinde ingorane: Mu bikorwa aho voltage yinjiye irenga 50V, komeza wemeze neza volteji y'amashanyaraziinductorn'uwakoze, ntabwo ari agaciro k'inductance gusa.

8. Isat na Irms ni iki? Ni iyihe igomba kwitabwaho mu gihe cyo gutoranya?

Ibi ni ibipimo bibiri by'ingenzi by'ubushyuhe:
* Isat (Umuyoboro w'amazi uhagije): Umuyoboro w'amazi iyo inductance igabanutse ku gipimo runaka (urugero, 30%). Kurenga iki giciro bitera kugabanuka gutunguranye k'ubushobozi bwo kubika ingufu bwa inductor, bishobora gutuma habaho kudahindagurika mu muyoboro w'amashanyarazi.
* Irms (umuyoboro wa RMS): Umuyoboro w'amashanyarazi aho ubushyuhe bw'ubuso bw'inductor bugera ku gaciro kagenwe (urugero, 40°C), ahanini bigenwa no gutakaza umuringa (DCR).
* Ihame: Mu guhitamo, ibipimo byombi bigomba kuzuza ibisabwa na serivise.

9. Ese kuba ufite DCR nke (DC resistance) buri gihe ni byiza kurushaho?

Yego. Uko DCR iba nke, ni ko umuringa uba muto, ni ko ubushobozi bwo guhindura ingufu burushaho kwiyongera, kandi ubushyuhe burushaho kwiyongera. Ariko, kuri ubwo bunini bumwe, gukurikirana DCR iba nke cyane akenshi bivuze kugabanuka k'umuvuduko w'amashanyarazi, bisaba gutandukana hashingiwe ku buryo bwihariye bwo kuyikoresha (haba mu gushyira imbere ubushobozi bwo gukoresha ingufu nyinshi cyangwa ububiko bw'ingufu nyinshi).

10. Uburyo bwo gupima ubwiza bw'ikintuinductor ?

Urubanza rw'ibanze rushobora gufatwa binyuze mu ngingo zikurikira:
*Isura: Ubuso bugomba kuba buringaniye kandi bworoshye, nta macupa cyangwa imitumba, kandi agapfundikizo k'udupira kagomba kuba kengera.
*Imbaraga z'ubudodo: Ibikoresho bishongeshejwe bigomba kuba bikomeye kandi ntibivunike byoroshye.
*Ubudahangarwa bw'isoda: Nyuma yo kongera gukoresha soda, umubiri ntugomba kugira ibara cyangwa imitumba igaragara.

11. Kuki bishobora guhuzwaabakora inductorsguhindurwa kuba guto no kuba guto?

A: Kubera ikoranabuhanga rya poda metallurgy, ntabwo isaba icyuho cya magnetic core assembling nk'uko bisanzwe bigenda ku baterankunga, kandi imiterere yayo ni ntoya cyane. Muri iki gihe, ikoranabuhanga rishobora kugera ku bicuruzwa bito cyane bifite ubugari buri munsi ya 0.5mm, bikaba bikwiriye cyane kuri telefoni zigendanwa n'ibikoresho byambarwa.

12. Ni iyihe gahunda ya "T-Core"?

Iri ni ikoranabuhanga rigezweho mu miterere rituma uburyo bwo gukwirakwiza urusobe rw'amashanyarazi hakoreshejwe uburyo bwihariye bwo gushushanya no gufunga, rigagabanya igihombo no kunoza imikorere myiza no gukwirakwiza ubushyuhe.

13. Ese inductor ivanze izagwa?

Ibikoresho fatizo ahanini ni ifu y'icyuma. Iyo igipfundikizo cyo gukingira (nk'ibuye rya epoxy) kiri ku buso bw'umuti giteweho ibipimo bitangana cyangwa cyangiritse, koko hari ibyago byo kwangirika no kwangirika mu gihe cy'ubushuhe bwinshi n'umunyu uterwa. Ikoranabuhanga ryo gutera imiti ryikora ku buryo bwikora rishobora gukumira iki kibazo neza.
