2.1 Ngwa nke Nanocrystalline isi ihe na elu ugboro transformer
        dị ugbu a, elu ugboro nkesa n'ozuzu iji ferrite cores. Atụnyere arụmọrụ nke VITROPERM 5OOF ígwè dabeere ultra-micronized magnetik isi na N67 usoro ferrite isi na-emepụta abụọ German enyemaka, magnetik permeability nke Nanocrystalline isi na-agbanwe ọtụtụ obere na okpomọkụ karịa ferrite isi. Ọ nwere ike melite kwụsie ike na ntụkwasị obi nke ịmafe ike ọkọnọ. Mgbe okpomọkụ mgbanwe ahụ, ọnwụ nke Nanocrystalline isi bụ nnọọ ala karịa nke ferrite isi.
Ke adianade do, ferrite isi nwere a ala Curie ebe okpomọkụ na-adị mfe demagnetized na elu okpomọkụ. Ọ bụrụ na a super microcrystalline isi e ji eme ka a transformer, ego nke mgbanwe magnetik itinye n'ọkwa ini ọrụ ga-agbanwe site O. 4T mụbara 1.

2.2. Ngwa nke Nanocrystalline isi ihe na-emekarị mode inductor
        Mgbe a nkịtị mode inductor (makwaara dị ka a nkịtị mode ịkpagbu) na chepụtara na-eji ihe ultrafine crystal isi, a nnukwu ego nke inductance nwere ike enwetara site asọfe a ole na ole nke ibe, si otú mbenata ọla kọpa ọnwụ na ichekwa waya ma mbenata The olu nke ndị nkịtị mode inductor bụ obere. Common mode inductors mere na Nanocrystalline cores nwere nnukwu nkịtị-mode ntinye ọnwụ na-ebelata nkịtị-mode nnyonye anya n'elu a dum ugboro nso, na iwepu mkpa maka mgbagwoju nyo na sekit na sekit. A nkịtị mode inductor na-chepụtara site na iji a ferrite isi ma na ihe Nanocrystalline isi, karị.
2.3. Ngwa nke Nanocrystalline isi na EMI nyo
        The cobalt dabeere Nanocrystalline isi Vit-ROVAC 6025Z emepụta site VAC nwere ike n'ọtụtụ ebe na EM1 nyo nke ịmafe ike esenyịn, nke nwere ike n'ụzọ dị irè-ebelata ọgọ voltaji N'ịbụ mgbanwe dị ngwa nke ugbu a. A ọgọ suppressor nwere ike chepụtara site asọfe otu ma ọ bụ ọtụtụ ibe ọla kọpa waya na Nanocrystalline isi. Ọdịdị dị nnọọ mfe na suppression nke mkpọtụ nnyonye anya dị nnọọ mma. The VITROVAC 6025Z Nanocrystalline isi nwere a nnọọ ala isi ọnwụ na a elu squareness ruru. Mgbe ugbu a na mberede na-agbanwe ka efu, ọ na a nnukwu inductance, nke nwere ike ime agbara ugbu a nke rectifier.
        Mgbe ugbu a na-tụgharịa na, na isi bụ na a jupụta ala na nwere a nnọọ ala inductance. Mgbe ugbu a esịmde ọrụ mgbe (remanence ebe)
        mgbe ugbu a na agbanyụrụ, na nke ugbu a na-aga n'ihu na-adịghị mma direction ruru ka agbara mgbake oge nke rectifier. Ebelata, ma Nanocrystalline isi nwere nnọọ elu magnetik permeability, nke ga-ewetara a nnukwu ego nke inductance, otú ọ na-aga site n'ọnụ ọrụ mgbe (kwesịrị-ederịta akwụkwọ ozi oge mgbe reverse elu ugbu a Iye emee). Ọ bụ ozugbo na-arụ ọrụ mgbe (ie, agbara remanent ebe), na mgbe ahụ magnetized na-amalite ọzọ. Nke a njirimara n'igbochi elu ugbu a nke rectifier a na-akpọ "soft mgbake."

Dị ka ọnụ ọgụgụ, arọ nke magnetik akụrụngwa bụ n'ozuzu 30% 40% nke ngụkọta arọ nke Ntụgharị, na olu akụkọ ihe 20% 30% nke ngụkọta olu. N'ihi na elu ugboro ike ọkọnọ nke modular imewe, nkezi nke olu na arọ nke magnetik akụrụngwa Ọ ga-ọbụna elu. Ke adianade do, magnetik mmiri bụ isi ihe dị mkpa na-emetụta ndị na-akpa ike arụmọrụ nke ike ọkọnọ mmepụta na mmepụta ripple.
