Nanocrystalline, amatchedwanso nano-amorphous, ndi mtundu watsopano zakuthupi maginito. Nanocrystalline mitima amakumana ndi anthu awo maginito permeability mkulu, mkulu squareness chiŵerengero, pakati imfa otsika ndi mkulu bata kutentha.
        The Nanocrystalline pachimake ali mkulu machulukitsidwe maginito kupatsidwa ulemu (1.l ~ 1.2T), mkulu maginito permeability, otsika coercivity, imfa otsika ndi kukhazikika wabwino, kuvala kukana ndi kukana dzimbiri. Mtengo wochepa ali bwino mtengo / ntchito chiŵerengero pakati zitsulo zofewa mitima onse maginito zakuthupi. The kugwiritsidwa ntchito kuti Nanocrystalline pakati chikudziwika ngati "zinthu zobiriwira" ndipo chimagwiritsidwa ntchito m'malo pakachitsulo zitsulo, permalloy ndi ferrite lalikulu, sing'anga ndi yaing'ono zosiyanasiyana pafupipafupi mkulu (20-100 kHz) kusintha amapereka mphamvu. Mphamvu thiransifoma chachikulu, ulamuliro thiransifoma, yoweyula inductor, yosungirako mphamvu inductor, riyakitala, maginito mkuzamawu, zimalimbikitsa riyakitala pachimake, EMC fyuluta wamba mode inductor ndi masiyanidwe mode inductor pachimake. IDSN kakang'ono kudzipatula thiransifoma pakati amadziwikanso ankagwiritsa ntchito zosiyanasiyana thiransifoma mitima ya mwatsatanetsatane chomwecho.
1 waukulu mbali ya Nanocrystalline pakati
The VITROPERM 500F chitsulo ofotokoza Nanocrystalline pachimake ali mbali zotsatirazi:
1) waukulu kwambiri koyamba permeability, μ = 30 000 ~ 80 000, ndi permeability maginito zimasiyanasiyana pang'ono kwambiri ndi kachulukidwe kamwazi ndi kutentha;
2) Phata imfa ndi otsika kwambiri ndipo sasintha ndi kutentha osiyanasiyana 40 +120 ° C;
3) waukulu kwambiri machulukitsidwe kamwazi kachulukidwe (BS = 1.2T), nalola m'munsi kusinthitsa pafupipafupi kusankhidwa, amene angathe kuchepetsa ndalama kusintha amapereka mphamvu ndi Zosefera EMI;
4) Phata maginito ndi encapsulated ndi epoxy utomoni, amene ali mkulu mawotchi mphamvu, palibe hysteresis ndi anatambasula, ndipo akhoza kulimbana amphamvu kugwedera;
5) akhoza m'malo miyambo ferrite pakati kuchepetsa voliyumu ya kusintha magetsi. Kusintha mbali odalirika.
2, ntchito Nanocrystalline maginito pakati pa kusintha magetsi
2.1 Kugwiritsa Nanocrystalline pachimake nkhani mkulu pafupipafupi thiransifoma
        Pakali pano, mkulu pafupipafupi tiransifoma zambiri ntchito mitima ferrite. Poyerekeza ntchito ya VITROPERM 5OOF chitsulo ofotokoza kopitilira muyeso-micronized maginito pachimake ndi N67 mndandanda ferrite pakati umatulutsa bulanchi awiri German, ndi permeability maginito ya Nanocrystalline pakati amasintha kuli ndi kutentha kuposa pachimake ferrite. Zimakhala bwino wokhazikika ndi zodalirika kotunga kusinthitsa mphamvu. Pamene kusintha kutentha, imfa ya Nanocrystalline pachimake kwambiri m'munsi kuposa pachimake ferrite.
Komanso, pakati ferrite ali otsika Curie mfundo kutentha ndi mosavuta demagnetized pa kutentha. Ngati wapamwamba microcrystalline pachimake ntchito kupanga thiransifoma, kuchuluka kwa kusintha mu kupatsidwa ulemu maginito pa ntchito zikhoza kusintha kwa O. 4T kuchuluka kwa 1. Muchipangano chakale, pafupipafupi opaleshoni ya mphamvu lophimba chubu yafupika pansipa 100 kHz.
2.2. Kugwiritsa Nanocrystalline pachimake mu mode inductor wamba
        Pamene wamba mode inductor (yemwenso amadziwika monga mode kutsamwa wamba) ndi Kuzipeka ntchito ultrafine galasi pachimake, wambirimbiri inductance akhoza akamagwira kumulowetsa ochepa motsatana, potero kuchepetsa imfa mkuwa ndi kupulumutsa waya ndi kuchepetsa voliyumu ya mode inductor wamba yaing'ono. Common mode inductors anapanga ndi Nanocrystalline mitima ndi mkulu wamba mode mayikidwe imfa ndi kupondereza wamba mode kulowelera pa lonse pafupipafupi osiyanasiyana, kuchotsa kufunika zovuta madera fyuluta. A mode inductor wamba ndi Kuzipeka pogwiritsa ntchito pakati ferrite ndi Nanocrystalline pachimake, motero.
2.3. Kugwiritsa Nanocrystalline pachimake mu EMI fyuluta
        The cobalt ofotokoza Nanocrystalline pakati VIT-ROVAC 6025Z umatulutsa VAC akhoza ankagwiritsa ntchito mu EM1 fyuluta ya kusintha magetsi, kumene angakathandizidwe kupondereza kukwera voteji kwaiye kusintha mofulumira panopa. A suppressor kukwera akhoza Kuzipeka ndi kumulowetsa limodzi kapena angapo ankasinthana wa waya mkuwa pa Nanocrystalline pachimake. Kapangidwe Ndi yosavuta ndi yimitsira phokoso kusokonezedwa ndi zabwino kwambiri. The VITROVAC 6025Z Nanocrystalline pachimake ali otsika kwambiri pakati imfa ndi mkulu squareness chiŵerengero. Pamene panopa mwadzidzidzi akusintha ziro, izo akusonyeza ndi inductance zikuluzikulu, zimene chingamulepheretse panopa n'zosiyana wa rectifier lapansi.
        Pamene masiku ano anatembenukira, pachimake ndi boma zimalimbikitsa ndipo ali otsika kwambiri inductance. Pamene panopa umalandira opaleshoni mfundo (remanence mfundo)
        pamene masiku ano mwadzidzidzi, panopa akupitiriza malangizo oipa chifukwa n'zosiyana kuchira nthawi ya rectifier lapansi. Yafupika, koma Nanocrystalline pachimake ali mkulu kwambiri maginito permeability, umene mupereke wambirimbiri inductance, motero ipyole ongolankhula mfundo opaleshoni (zogwirizana ndi nthawi imene n'zosiyana pachimake panopa IR amapezeka). Ndi mwachindunji kufika ntchito (ie, n'zosiyana remanent mfundo), kenako nyese kuyamba mkombero wina. Mkhalidwe umenewu wa kupondereza pachimake panopa rectifier limatchedwa "zofewa kuchira."
        Ndi chitukuko ndi kukhwima kwa luso mphamvu zamagetsi, anthu pang'onopang'ono kuzindikira kuti zigawo maginito si zigawo zinchito okha amapereka mphamvu, komanso buku awo, kulemera ndi imfa chifukwa kwa chiwerengero ndithu mu makina lonse. Malinga ndi kafukufuku, kulemera kwa chigawo maginito zambiri 30% 40% ya kulemera okwana Converter, ndipo voliyumu chimachititsa 20% 30% buku okwana. Pakuti mkulu-pafupipafupi mphamvu kundipatsako kwa kapangidwe yodziyimira payokha, chiwerengero cha buku ndi kulemera kwa chigawo maginito Iwo adzakhala apamwamba. Komanso, zigawo maginito ndi chinthu chofunika kwambiri zokhudza ntchito zazikulu za magetsi linanena bungwe ndi linanena bungwe ripple. Choncho, pofuna kusintha mphamvu osalimba, dzuwa, ndi khalidwe linanena bungwe la magetsi, mozama kafukufuku iyenera kuchitikira kuchepetsa voliyumu, kulemera, ndi imfa ya chigawo maginito kukwaniritsa zofuna za chitukuko mphamvu. Tili ndi zifukwa zomveka kukhulupirira kuti Nanocrystalline mitima adzakhala ndi yotakata kwambiri ntchito chiyembekezo kusintha amapereka mphamvu.
