Potengera zomwe zikuchitika padziko lonse lapansi pakusunga mphamvu mwanzeru, kulumikizana opanda zingwe ndi zida zam'manja zonyamula zimayenera kupangidwa mwaluso kwambiri komanso kugwiritsa ntchito mphamvu zochepa. Chifukwa chake, inductor yamagetsi yomwe imayang'anira kutembenuza kosungirako mphamvu ndi kusefa kokonzanso mkati mwa gawo lamagetsi imakhala ndi gawo lofunikira lopulumutsa mphamvu.

Pakali pano, ntchito ya ferrite maginito zipangizo pang'onopang'ono sangathe kukwaniritsa miniaturization ndi mkulu zofunika panopa wainductor mphamvumankhwala. Ndikofunikira kusinthira kuzitsulo zamaginito zachitsulo zokhala ndi maginito ochulukirachulukira kuti mudutse luso lam'badwo wotsatira wa zinthu zazing'ono / zapamwamba zamakono ndikupanga ma frequency, miniaturized, kachulukidwe kake, komanso ma module amphamvu kwambiri. .

Pakali pano, luso Inductors Integrated zitsulo akukula kwambiri, ndi njira ina chitukuko ndi mkulu-kutentha co fired wosanjikiza Chip zochokera zitsulo mphamvu inductors. Poyerekeza ndi ma inductors ophatikizika, mitundu iyi ya ma inductors ili ndi maubwino osavuta a miniaturization, machulukitsidwe abwino kwambiri apano, komanso mtengo wotsika. Iwo ayamba kulandira chidwi kuchokera ku makampani ndipo adayikidwa pa kafukufuku ndi chitukuko. Akukhulupirira kuti posachedwapa, zitsulo mphamvu inductors adzakhala chimagwiritsidwa ntchito zosiyanasiyana mafoni katundu, Kukwaniritsa mchitidwe wa ntchito zanzeru ndi kupulumutsa mphamvu.

Mfundo za Power Inductor Technology

Mfundo yogwiritsira ntchito mphamvu yopangira mphamvu yomwe imagwiritsidwa ntchito mu gawo la mphamvu makamaka imasunga magetsi mu mawonekedwe a mphamvu ya maginito muzinthu za magnetic core. Pali mitundu yambiri yogwiritsira ntchito ma inductors, ndipo mitundu ya zida za maginito ndi zigawo zomwe zimagwiritsidwa ntchito pazochitika zilizonse zimakhala ndi mapangidwe ofanana. Nthawi zambiri, maginito a ferrite ali ndi chinthu chapamwamba Q, koma mtengo wodzaza maginito ndi 3000 ~ 5000 gauss; Mtengo wokwanira wa maginito wazitsulo zamaginito ukhoza kufika pa 12000 ~ 15000 Gauss, womwe umaposa kuwirikiza kawiri maginito a ferrite. Malinga ndi chiphunzitso cha maginito machulukitsidwe panopa, poyerekeza ndi maginito ferrite, maginito pachimake zitsulo adzakhala yabwino kwa mankhwala miniaturization ndi mkulu panopa kupanga.

Pamene panopa akudutsa gawo la mphamvu, kusintha kwachangu kwa transistors kumabweretsa kusintha kwaposachedwa kapena kwadzidzidzi pakalipano kusintha kwa ma waveform mu inductor ya mphamvu, zomwe zimapangitsa kuti maonekedwe a inductor akhale ovuta komanso ovuta kuwongolera.

Inductor imapangidwa ndi maginito core materials ndi coils. Inductor mwachilengedwe imalumikizana ndi mphamvu yosokera yomwe ilipo pakati pa koyilo iliyonse, ndikupanga dera lofananira la resonance. Chifukwa chake, ipanga Self resonant Frequency (SRF). Pamene mafupipafupi ali apamwamba kuposa awa, inductor idzawonetsa mphamvu, kotero sichingakhalenso ndi ntchito yosungirako mphamvu. Choncho, pafupipafupi ntchito ya inductor mphamvu ayenera kukhala m'munsi kuposa kudzikonda resonant pafupipafupi kukwaniritsa mphamvu yosungirako mphamvu.

M'tsogolomu, kulankhulana kwa mafoni kudzakula kupita ku 4G / 5G kutumiza deta yothamanga kwambiri. Kugwiritsa ntchito ma inductors pama foni apamwamba kwambiri komanso msika wayamba kuwonetsa kukula kwakukulu. Pafupifupi, foni iliyonse yanzeru imafuna ma inductors 60-90. Kuphatikiza pa ma module ena monga LTE kapena tchipisi tazithunzi, kugwiritsa ntchito ma inductors pafoni yonse ndikofunikira kwambiri.

Pakali pano, mtengo wa unit ndi phindu lama inductorsndizokwera kwambiri poyerekeza ndi ma capacitors kapena resistors, kukopa opanga ambiri kuti agwiritse ntchito kafukufuku ndi kupanga. Chithunzi 3 chikuwonetsa lipoti loyesa la IEK pamitengo yapadziko lonse lapansi yotulutsa ndi msika, zomwe zikuwonetsa kukula kwakukulu kwa msika. Chithunzi 4 chikuwonetsa kuwunika kwa kagwiritsidwe ntchito ka inductor pazida zosiyanasiyana zam'manja monga mafoni am'manja, ma LCD, kapena NB. Chifukwa cha mwayi waukulu wamabizinesi pamsika wa inductor, opanga ma inductor padziko lonse lapansi akuwunika mwachangu makasitomala azipangizo zam'manja ndikuyesetsa kuti agwiritse ntchito kafukufuku ndi chitukuko cha zatsopano.inductor mphamvuzopangidwa kuti apange zida zam'manja zogwira mtima komanso zotsika mphamvu.

Kugwiritsa ntchito kochokera kwa ma inductors amagetsi kumakhala makamaka pamagalimoto, mafakitale, ndi zinthu zamagetsi zamagetsi. Mitundu ndi mawonekedwe a ma inductors amagetsi omwe amagwirizana ndi momwe amagwiritsira ntchito amasiyana. Pakalipano, msika waukulu kwambiri wogwiritsira ntchito makamaka malonda ogula.
