Hlau hmoov Core

Hlau hmoov core yog ib lo lus nrov rau cov khoom sib nqus Fe3O4. Nws yog tsuas yog siv nyob rau hauv hluav taws xob circuits los daws qhov teeb meem ntawm electromagnetic compatibility (EMC). Hauv kev siv tswv yim, ntau lwm yam tshuaj yuav raug ntxiv raws li kev lim dej sib txawv hauv qhov sib txawv.

Lub clutter saum cov hlau tsuas yog daws nws cov teeb meem electromagnetic compatibility los ntawm lub nplhaib sib nqus. Thaum ib qho kev sib nqus ntawm lub nplhaib hla lub nplhaib sib nqus, cov yam ntxwv ntawm lub nplhaib sib nqus ua rau cov hlua khi tam sim no hloov mus rau hauv lub zog sib nqus thiab qee qhov cua sov, uas yog siv. Txhawm rau kom tsis txhob cuam tshuam.

Cov khoom siv ntawm lub nplhaib hlau nplaum feem ntau yog hlau hmoov hlau (tus nqi qis, siv dav), thiab cov ntaub ntawv tsis tshua muaj hauv ntiaj teb.

Suab nrov

Vim yog lub tshuab loj loj ntawm cov khoom sib nqus sib nqus hauv nws cov qauv, lub suab nrov ntawm cov tub ntxhais hlau yog me me. Thaum muab piv cov suab nrov ntawm lub reactor nrog annular ferrite hlau core thiab cov hlau nplaum sib nqus reactor nrog tib qhov loj, zoo li thiab inductance, lub suab nrov ntawm lub reactor nrog cov khoom sib nqus sib nqus yog txo los ntawm 10dB rau sine yoj voltage ntawm 500Hz ~ 20kHz. .

Tau ntev, cov khoom siv sib nqus siv hauv cov khoom siv hluav taws xob hluav taws xob ib txwm yog cov khoom siv hlau. Hauv kev lag luam ntau zaus, cov khoom siv no muaj cov khoom sib nqus zoo heev, tab sis nws cov yam ntxwv tsis zoo zuj zus ntxiv nrog qhov nce ntawm zaus. Ntawm qhov tsis sib xws, cov khoom siv ferrite muaj cov yam ntxwv zoo heev, tab sis nws tsis tuaj yeem siv los ua cov cuab yeej siv hluav taws xob vim nws qhov sib nqus sib nqus flux tsawg. Nias hmoov sib nqus core cov khoom muaj cov yam ntxwv siab zaus thiab siab sib nqus flux ceev, uas tuaj yeem siv dav hauv thaj chaw uas hluav taws xob hlau thiab ferrite siv tsis tau. Cov khoom no yog tsim los ntawm pwm, uas tuaj yeem ua rau ntau yam duab thiab muaj cov yam ntxwv ntawm machinability. Raws li cov khoom siv tshiab dav siv hauv kev siv hluav taws xob hluav taws xob thiab kev tiv thaiv EMI, nws yuav tsum tau them nyiaj rau.
