Buck Inductor (Yosinthira Voltage Yotsika pansi)
Buck inductor ndi gawo lamagetsi lomwe ntchito yake yayikulu ndikuchepetsa voteji yolowera ku voliyumu yomwe mukufuna yomwe ili yotsutsana ndi inductor ya boost.
Ubwino watsatanetsatane wawonetsedwa pansipa:
(1) Voliyumu yaying'ono, makulidwe ang'onoang'ono, mogwirizana ndi kachitidwe kachitukuko kamagetsi.
(2) Mapiritsi athyathyathya okhala ndi ma electromagnetic coupling abwino, mawonekedwe osavuta, magwiridwe antchito apamwamba komanso kusasinthika kwa magawo.
(3) Chifukwa waya wamkuwa wathyathyathya amagwiritsidwa ntchito kwambiri, zotsatira za khungu zimatha kugonjetsedwa, zomwe zimapangitsa kuti pakhale nthawi yayitali yogwira ntchito komanso kachulukidwe kamphamvu kwambiri, pafupipafupi pakati pa 50kHz ndi 300kHz.
(4) Makhalidwe abwino kwambiri otaya kutentha, tinthu tating'onoting'ono tokhala ndi malo okwera kwambiri mpaka kuchuluka kwa voliyumu ndi njira yayifupi kwambiri yotentha, yabwino kutulutsa kutentha.
(5) Kuchita bwino kwambiri, mawonekedwe apakati a maginito a mawonekedwe apadera a geometric amatha kuchepetsa kutayika kwakukulu.
(6) Kusokoneza kwamagetsi kwamagetsi kakang'ono.
(7) Kugawa magawo ofanana;
(8) Kupanga zodziwikiratu, ntchito zotsika mtengo.
1. Makhalidwe abwino osinthika.Chifukwa inductance yamkati ndi yaying'ono, inertia ya electromagnetic ndi yaying'ono, ndipo liwiro loyankhira liri mwachangu (liwiro losinthira lili pa dongosolo la 10ms).Imatha kukumana ndi kukula kwanthawi yayitali ikagwiritsidwa ntchito pamagetsi amtundu wathyathyathya, ndipo sikophweka kutulutsa mphamvu yanthawi yayitali ikagwiritsidwa ntchito pochepetsa mphamvu zamagetsi.The linanena bungwe riyakitala osati ntchito zosefera.Ilinso ndi ntchito yowongolera mawonekedwe osinthika.
2. Kuchita bwino kulamulira.Itha kuwongoleredwa ndi mphamvu yaying'ono yoyambitsa, ndipo mawonekedwe osiyanasiyana akunja angapezeke kudzera munjira zosiyanasiyana zoyankha.The panopa ndi voteji akhoza kusinthidwa uniformly ndipo mwamsanga mu osiyanasiyana lalikulu, ndipo n'zosavuta kuzindikira chipukuta misozi voteji maukonde.
3. Poyerekeza ndi ma jenereta owotcherera a DC arc, ndizopulumutsa mphamvu, zimapulumutsa zinthu komanso phokoso lochepa.
4. Derali ndi lovuta kwambiri ndipo limagwiritsa ntchito zipangizo zamagetsi.Nthawi zambiri amagwiritsidwa ntchito chifukwa cha khalidwe loipa la zipangizo zamagetsi kapena khalidwe la msonkhano, zomwe zimabweretsa kulephera kwa makina otsekemera ndi kuchepetsa moyo wautumiki.
The riyakitala wa DC kuwotcherera makina makamaka amasewera ntchito zosefera, kuti kuwotcherera panopa khola, makamaka ang'onoang'ono kuwotcherera panopa, imagwira ntchito yosamalira arc, ndi kupewa kuwotcherera arc.
Amagwiritsidwa ntchito kwambiri pamagetsi osiyanasiyana osinthira magetsi ndi zida zina zamagetsi kuti athetse "kuipitsa" kwa zida zamagetsi pagulu lamagetsi komanso kusokoneza kwamagetsi pamagetsi amagetsi.
