Integrated inductors

Njira ziwiri zodziwika bwino zaukadaulo pazomwe zikuchitika pamagetsi amagetsi ndi maginito.Lero tikambirana zina zaIntegrated inductors.

Integrated inductors imayimira njira yofunikira pakukula kwa maginito opita kufupipafupi, miniaturization, kuphatikiza, ndi magwiridwe antchito apamwamba mtsogolo. Komabe, iwo sanapangidwe kuti alowe m'malo mwa zigawo zonse zachikhalidwe, koma m'malo mwake akhale zisankho zazikulu pamagawo awo aukadaulo.

Integrated inductor ndikusintha kwakusintha kwa ma inductors a bala, komwe kumagwiritsa ntchito ukadaulo wa zitsulo zamafuta kuponya ma coils ndi maginito.

Chifukwa chiyani ndi chitukuko?

1. Kudalirika kwambiri: Ma inductors achikhalidwe amagwiritsa ntchito maginito cores omatira, omwe amatha kusweka ndi kutentha kwambiri kapena kugwedezeka kwa makina. Mapangidwe ophatikizika amakutira koyilo mkati mwazinthu zolimba zamaginito, zopanda zomatira kapena mipata, ndipo zimakhala ndi mphamvu zotsutsa kugwedezeka komanso zotsutsana ndi zovuta, zomwe zimathetsa vuto lalikulu lodalirika la ma inductors achikhalidwe.

2. Kusokoneza kwapansi kwa electromagnetic: Koyiloyo imatetezedwa kwathunthu ndi maginito ufa, ndipo mizere ya maginito imatsekeredwa bwino mkati mwa chigawocho, kuchepetsa kwambiri ma radiation akunja a electromagnetic (EMI) komanso kukhala osagwirizana kwambiri ndi kusokoneza kwakunja.

3. Kutayika kochepa & magwiridwe antchito apamwamba: The alloy powder maginito zinthu zomwe zimagwiritsidwa ntchito zimakhala ndi mipata yogawa mpweya, kutayika kwapakati pama frequency apamwamba, machulukitsidwe apamwamba, komanso mawonekedwe abwino kwambiri a DC kukondera.

4. Miniaturization: Ikhoza kukwaniritsa inductance yaikulu ndi machulukitsidwe apamwamba panopa mu voliyumu yaing'ono, kukwaniritsa zofunikira za "zing'onozing'ono komanso zogwira mtima kwambiri" zamagetsi zamagetsi.

Zovuta:

* Mtengo: Njira yopangira zinthu ndizovuta, ndipo mtengo wazinthu zopangira (aloyi ufa) ndi wokwera kwambiri.

* Kusinthasintha: Pamene nkhungu ikamalizidwa, magawo (mtengo wa inductance, saturation current) amakhazikika, mosiyana ndi maginito a rod inductors omwe amatha kusinthidwa mosavuta.

Malo ogwiritsira ntchito: DC-DC kutembenuza mabwalo pafupifupi m'magawo onse, makamaka pazochitika zomwe zimafuna kudalirika kwambiri ndi ntchito, monga:

* Zamagetsi zamagalimoto: unit control unit, ADAS system, infotainment system (zofunikira kwambiri).

* Khadi lazithunzi zapamwamba / seva CPU: VRM (module yoyendetsera magetsi) yomwe imapereka kuyankha kwakanthawi kochepa komanso kwanthawi yayitali pachimake ndi kukumbukira.

* Zida zamafakitale, zida zolumikizirana pa intaneti, ndi zina.

* Pankhani ya kutembenuka kwa mphamvu ndi kudzipatula (zosintha), ukadaulo wa PCB wathyathyathya ukukhala chisankho chomwe chimakondedwa pamagwiritsidwe apakati mpaka apamwamba komanso apakati.

* Pankhani yosungiramo mphamvu ndi kusefa (ma inductors), ukadaulo wophatikizika wakuumba ukusintha mwachangu ma inductors azikhalidwe zamaginito osindikizidwa pamsika wapamwamba kwambiri, kukhala chizindikiro chodalirika kwambiri.

M'tsogolomu, ndi kupita patsogolo kwa sayansi ya zinthu (monga zoumba zotenthetsera zotentha zotsika, zida zabwino zamaginito ufa) ndi njira zopangira, matekinoloje awiriwa apitiliza kusinthika, ndikuchita bwino kwambiri, ndalama zowongoleredwa, komanso ntchito zambiri.
