Nanocrystalline, eyaziwa nangokuthi i-nano-amorphous, uhlobo olusha impahla kazibuthe. Nanocrystalline cores abathandayo abantu permeability zabo eziphakemeyo kazibuthe, okusezingeni eliphezulu squareness isilinganiso, ongaphakeme core ukulahlekelwa kanye okusezingeni eliphezulu lokushisa ukuzinza.
        I Nanocrystalline core has ukugcwaliswa okusezingeni eliphezulu lokungeniswa kazibuthe (1.l ~ 1.2T), okusezingeni eliphezulu permeability kazibuthe, coercivity ongaphakeme, ukulahlekelwa ongaphakeme nokuzinza ezinhle, ukugqoka ukumelana naso futhi kwenze ukugqwala ukumelana. Intengo ongaphakeme has the best amanani / ukusebenza isilinganiso phakathi kwazo zonke ezithambile kazibuthe impahla cores metal. Indaba esetshenziswa ukwenza Nanocrystalline core is ngokuthi "impahla eluhlaza" eyaziwa futhi sisetshenziswa kabanzi ukufaka esikhundleni Silicon steel, permalloy futhi ferrite esikhulu, aphakathi nendawo kanye elincane ezinhlotsheni ezihlukahlukene imvamisa high (20-100 kHz) ukushintsha segezi. Amandla transformer main, ukulawula transformer, igagasi inductor, isitoreji amandla inductor, ophendulayo, amplifier kazibuthe, ayegcwele ophendulayo nengaphakathi EMC isihlungi imodi evamile inductor futhi umehluko imodi inductor core. IDSN miniature ngabodwa transformer core nayo kabanzi izinhlobo ezahlukene transformer cores of ngokunemba efanayo.
1 izici eziyinhloko Nanocrystalline core
I VITROPERM 500F yensimbi ezisekelwe Nanocrystalline core has izici ezilandelayo:
1) eliphezulu kakhulu permeability kokuqala, μ = 30 000 ~ 80 000, kanye permeability kazibuthe kuyahlukahluka kancane kakhulu nge kwabantu ecucuza kanye lokushisa;
2) Ukulahlekelwa core liphansi kakhulu futhi akashintshi njengoba lokushisa kule ezahlukene 40 kuya +120 ° C;
3) ukugcwaliswa okusezingeni eliphezulu kakhulu ecucuza kwabantu (Bs = 1.2T), avumele aphansi usuke imvamisa ukuze kukhethwe, okuyinto kunganciphisa izindleko ukushintsha segezi kanye EMI izihlungi;
4) Lo simende kazibuthe is encapsulated ngu epoxy resin, okuyinto has high amandla mechanical, akukho hysteresis futhi ngilulekela, futhi ekwazi ukumelana namandla vibration eqinile;
5) Kungaba esikhundleni bendabuko ferrite core ukunciphisa ivolumu ukushintsha ukuphakelwa kukagesi. Thuthukisa izingxenye okuthembekile.
2, isicelo Nanocrystalline core magnetic ukushintsha ukuphakelwa kukagesi
2.1 Isicelo Nanocrystalline core impahla e okusezingeni eliphezulu imvamisa transformer
        Njengamanje, high imvamisa transformers ngokuvamile zisebenzisa cores ferrite. Ukuqhathanisa ukusebenza kohlelo VITROPERM 5OOF yensimbi ezisekelwe ultra-micronized core kazibuthe kanye N67 uchungechunge ferrite core ezivezwa ezingaphansi ezimbili isiJalimane, le permeability kazibuthe we Nanocrystalline core eshintsha ingasaphathwa nge lokushisa ngaphandle core ferrite. Kungaba ngcono ukuzinza kanye ukuthembeka kwamandla usuke. Lapho ushintsho lokushisa, ukulahlekelwa Nanocrystalline core lingaphansi kakhulu kunalelo nengaphakathi ferrite.
Ngaphezu kwalokho, core ferrite has a ongaphakeme Curie iphuzu lokushisa futhi kalula demagnetized ngamazinga ashisa kakhulu. Uma super microcrystalline core isetshenziswa ukwenza kwe-transformer, inani ushintsho lokungeniswa kazibuthe ngesikhatsi operation singashintshwa kusuka O. 4T anda ukuze 1. OT, imvamisa yokusebenza amandla switch tube kuyehla kube ngezansi 100 kHz.
2.2. Isicelo Nanocrystalline core kwimodi evamile inductor
        Lapho inductor imodi evamile (eyaziwa ngokuthi yi- ezivamile imodi binda) is bhila Usebenzisa ultrafine crystal core, semali inductance ingatholakala emazombezombe inombolo encane ematfuba, ngaleyo ndlela kuncishiswe ukulahleka zethusi nokulonda wire kanye nokunciphisa umthamo we ezivamile imodi inductor incane. Imodi Common inductors enziwe Nanocrystalline cores babe okusezingeni eliphezulu ezivamile-mode Ukufakwa ukulahlekelwa nokucindezela ezivamile-mode ukuphazamiseka phezu ububanzi imvamisa ububanzi, isidingo eziyinkimbinkimbi isihlungi izifunda. Inkolelo evamile mode inductor is bhila ngokusebenzisa core ferrite kanye core Nanocrystalline, ngokulandelana.
2.3. Isicelo Nanocrystalline core e EMI isihlungi
        I ayibe ezisekelwe Nanocrystalline core VIT-ROVAC 6025Z ezivezwa Vac kungenziwa kabanzi lemifanekiso EM1 ka ukushintsha ukuphakelwa kukagesi, okungase ukucindezela ngempumelelo voltage spike eyenziwe yokuguquka zamanje. A spike suppressor kungenziwa bakhiwe emazombezombe eyodwa noma ezimbalwa ematfuba zethusi wire phezu Nanocrystalline core. Isakhiwo silula futhi nokucindezela umsindo ukuphazamiseka muhle kakhulu. I VITROVAC 6025Z Nanocrystalline core has a aphansi kakhulu core ukulahlekelwa kanye okusezingeni eliphezulu squareness isilinganiso. Lapho wamanje kungazelelwe kuqanda, liveza inductance ezinkulu, okungase kuphazamise zamanje reverse of the rectifier.
        Lapho wamanje sivuliwe, umnyombo isebujameni elihlale futhi inductance aphansi kakhulu. Lapho wamanje ufinyelela yokusebenza iphuzu (remanence iphuzu)
        lapho yamanje ivaliwe, wamanje uyaqhubeka ohlangothini ezimbi ngenxa reverse isikhathi nokuvulwa rectifier. Encishisiwe, kodwa umongo Nanocrystalline has a permeability eliphezulu kakhulu kazibuthe, okuzokwenza ukwethula semali inductance, ngakho akayi ngokusebenzisa theory yokusebenza iphuzu (kufanele luhambisane okwamanje lapho reverse isiqongo IR zamanje kwenzeka). It kuze kube seqophelweni zokusebenza (ie, iphuzu reverse remanent) ngokuqondile, bese uzibuthe ukuqala komunye umjikelezo. Lesi sici abacindezela zamanje isiqongo we rectifier ibizwa ngokuthi "yokutakula esithambile."
        Nge ukuthuthukiswa nokuvuthwa kwamandla electronics nobuchwepheshe, abantu kancane kancane bayaqaphela ukuthi izingxenye kazibuthe akuzona izingxenye obusebenzayo kuphela amandla kagesi, kodwa futhi ivolumu yabo, isisindo ukulahlekelwa akhawunti ingxenye eside lonke umshini. Ngokwezibalo, isisindo ingxenye kazibuthe ngokuvamile 30% kuya ku-40% we isisindo ingqikithi Converter, futhi umthamo ebangela 20% kuya ku-30% umthamo isamba. Ukuze ephezulu imvamisa amandla supply design Modular, inani lemikhaya ivolumu kanye nesisindo esemazweni kazibuthe Kuyoba ngisho ephakeme. Ngaphezu kwalokho, izingxenye kazibuthe kukhona esibalulekile ezithinta ukusebenza othakazelisayo amandla supply okukhipha futhi okukhipha yezwakala. Ngakho-ke, ukuze sithuthukise kwabantu amandla, ukusebenza kahle, futhi okukhipha izinga amandla supply, ngo-ejulile ucwaningo okufanele iqhutshwe ukunciphisa ivolumu, isisindo, futhi ukulahlekelwa ingxenye kazibuthe ukuze kuhlangatshezwane nezidingo nentuthuko amandla. Sinesizathu sokukholelwa ukuthi Nanocrystalline cores uzoba ubanzi kakhulu isicelo themba ukushintsha segezi.
