Nanocrystalline, okwabizwa ngokuba nano-amorphous, uhlobo olutsha izinto ngemagnethi. Umphakathi Nanocrystalline bathandwayo abantu permeability zabo eziphakamileyo owahluke ngokwemvelo, squareness umlinganiselo phezulu, phantsi engundoqo ilahleko kunye nozinzo eliphezulu lobushushu.
        I Nanocrystalline ongundoqo uye Ukwanda eliphezulu induction magnetic (1.l ~ 1.2T), permeability eliphezulu owahluke ngokwemvelo, coercivity ephantsi, ilahleko eliphantsi kunye nozinzo elungileyo, anxibe ukumelana kunye nokumelana. Le ngexabiso eliphantsi unalo ixabiso / intsebenzo ratio ilungileyo phakathi kwazo zonke ezinye izinto ezithambileyo umphakathi metal ngemagnethi. Le nkcazelo isetyenziselwa ukwenza i core Nanocrystalline yaziwa ngokuba "luhlaza" kwaye lisetyenziswa jikelele endaweni lesilicon sentsimbi, permalloy kwaye ferrite nkulu, aphakathi kunye ezincinane kwiintlobo ezahlukeneyo asetyenziswa rhoqo (20-100 kHz) nokutshintsha izinto ngamandla. Power transformer ephambili, sombane ulawulo, wave inductor, inductor yokugcina amandla, reactor, msindo magnetic, okroqiweyo core reactor, EMC filter imo eqhelekileyo inductor kunye imo umahluko inductor engundoqo. IDSN yesikhumbuzo bodwa sombane olungundoqo lendlele ikwasetyenziswa kakhulu iintlobo ezahlukeneyo umphakathi transformer le ngendlela efanayo.
1 iimpawu eziphambili Nanocrystalline core
The VITROPERM 500F yentsimbi-based Nanocrystalline engundoqo na ezi mpawu zilandelayo:
1) permeability ophezulu kakhulu ekuqaleni, μ = 30 000 ~ 80 000, kwaye permeability magnetic kuyahlukahlukana encinane kakhulu loxinano obhobhozayo kunye ubushushu;
2) Le ilahleko ezingundoqo lisezantsi kakhulu kwaye akaguquguquki lobushushu kuluhlu-40 ukuya +120 ° C;
3) Ukwanda eliphezulu kakhulu ekumpompozeni mninzi (Bs = 1.2T), ukuvumela utshintshe nje frequency esezantsi ukuba ekhethiweyo, nto leyo ukunciphisa iindleko yokutshintsha izinto amandla kunye EMI amacebo;
4) Le olungundoqo magnetic le anyityiliselwe yi epoxy resin, nto leyo eye amandla aphezulu ngomatshini, akukho hysteresis, bazolulela, kwaye ukumelana lokungcangcazela esinxilisayo;
5) Ku nga indawo engundoqo ferrite yemveli ukunciphisa umthamo isenza i unikezelo amandla. Ukuphucula iindawo ethembekileyo.
2, isicelo ka Nanocrystalline ezingundoqo otsalayo xa isenza i umbane
2.1 Ukusetyenziswa izinto ezingundoqo Nanocrystalline eyenzeka kwi-frequency sombane phezulu
        Okwangoku, ngokuqhelekileyo abaguquli aqhelelkileyo sebenzisa umphakathi ferrite. Ukuthelekisa indlela yokusebenza VITROPERM 5OOF yentsimbi-based engundoqo ultra-micronized iinkcukacha ngemagnethi kunye N67 series ferrite core eziveliswa nkampani ezimbini German, lo permeability kazibuthe engundoqo Nanocrystalline utshintsho kakhulu ngaphantsi ne lobushushu ngaphezu core ferrite. Kunokuba ukuphucula uzinzo nokuthembeka unikezelo ziguquka amandla. Xa utshintsho ubushushu, ukulahleka undoqo Nanocrystalline ungaphantsi kakhulu ngaphezu koko ongundoqo ferrite.
Ukongeza, i-core ferrite unalo lobushushu Curie indawo ephantsi kwaye ngokulula demagnetized kwiqondo lobushushu eliphezulu. Ukuba engundoqo microcrystalline super isetyenziselwa ukwenza sombane, imali yokutshintsha induction magnetic ngexesha msebenzi zingatshintshwa O. 4T lanyuka ukuya 1. OT, rhoqo yokusebenza ye ityhubhu iswitshi amandla liye lancitshiswa ngaphantsi 100 kHz.
2.2. Ukusetyenziswa Nanocrystalline eziphambili inductor kwimo eqhelekileyo
        Xa inductor indlela eqhelekileyo (eyaziwa njenge ziliminxe indlela aqhelekileyo) sele bakhiwe usebenzisa i ultrafine crystal engundoqo, isixa esikhulu inductance zingafumaneka ngokubhijela inani elincinane amagophe, ngokwenjenjalo kuncitshiswe ilahleko ubhedu nokusindisa ucingo nokunciphisa umthamo inductor indlela eqhelekileyo incinci. Inductors mode Common ezenziwe Nanocrystalline umphakathi eliphezulu eziqhelekileyo-imowudi ilahleko ufako kthen uphazamiseko eqhelekileyo-mode phezu olubanzi uluhlu kwamaza, kokuphelisa imfuneko kwiisekethe lokucoca ezintsonkothileyo. A inductor mode eqhelekileyo sele bakhiwe ngokusebenzisa i core ferrite kunye nomxholo Nanocrystalline, ngokulandelelana.
2.3. Ukusetyenziswa Nanocrystalline ezingundoqo EMI lokucoca
        ayibe-based Nanocrystalline engundoqo VIT-ROVAC 6025Z eveliswe yi VAC ukuba ngokubanzi asetyenziswe EM1 lokucoca ubane unikezelo lwamandla, leyo ngempumelelo gqiba ombane spike eyenziwe utshintsho ngokukhawuleza ngoku. A suppressor spike kungenziwa bakhiwe ngokubhijela amathuba enye okanye ezininzi ucingo lobhedu kwi engundoqo Nanocrystalline. Isakhiwo Ilula kakhulu kwaye kwezithandani sokuphamazisa yengxolo kuhle kakhulu. I VITROVAC 6025Z Nanocrystalline ongundoqo umntu engundoqo ilahleko ephantsi kakhulu kwaye umlinganiselo ophezulu squareness. Xa ngoku utshintsha ngesiquphe zero, ivelisa inductance enkulu, nto leyo kunokuthintela ngoku ngasemva rectifier.
        Xa ngoku ivuliwe, undoqo sikwimo ifumile kwaye inductance ephantsi kakhulu. Xa ngoku lufika indawo yokusebenza (remanence point)
        xa umsinga icinyiwe, i liqhubeka kwicala HIV ngenxa yokuba ixesha ekuphulukwene ngasemva rectifier. Ku Ncitshisiwe, kodwa undoqo Nanocrystalline has a permeability eliphezulu kakhulu owahluke ngokwemvelo, nto leyo eza kunika isixa esikhulu inductance, ngoko loo nto iphumele eyingcingane indawo yokusebenza (kufuneka ne mzuzu xa kusenzeka-IR umva Incopho current). Kuyinto ngqo kwindawo yokusebenza (okt, ingongoma umva remanent), yaye emva koko magnetized ukuqala omnye umjikelo. Olu phawu abathintela incopho yangoku rectifier kuthiwa "recovery ethambileyo."
        Noko ke, uphuhliso kunye nokukhula zobugcisa elektroniki amandla, kancane abantu baqonde ukuba izakhi ngemagnethi nje amacandelo ezisebenzayo kuphela izinto ngamandla, kodwa umthamo wabo, ubunzima kunye nokulahlekelwa akhawunti ukuba inani elininzi umatshini lonke. Ngokutsho manani, ubunzima candelo otsalayo jikelele-30% ukuya kuma-40% ye-ubunzima zizonke lokuguqulela, kwaye umthamo akhawunti ye-20% kwi-30% yabo ngumthamo opheleleyo. Kuba eliphezulu rhoqo umbane zokuyilwa seemodyuli, umyinge umthamo kunye ubunzima icandelo otsalayo Kuya kuba ngaphezulu. Ukongeza, izakhi ngemagnethi na inkalo ebalulekileyo echaphazela indlela enefuthe ngayo umbane output kunye output yama- nzi. Ngoko ke, ukuze kuphuculwe lexinene amandla, ukusebenza, kunye nomgangatho output yobonelelo lwamandla, olunzulu uphando kufuneka kuqhutywe ukuze kuncitshiswe umthamo, ubunzima, kunye nelahleko icandelo otsalayo ukuhlangabezana neemfuno zophuhliso amandla. Kufuneka isizathu sokukholelwa ukuba Nanocrystalline umphakathi uya kuba nethemba isicelo ebanzi kakhulu xa isenza izinto ngamandla.
