Yuav ua li cas peb txheeb xyuas qhov zoo ntawm kev hloov DC hluav taws xob hloov pauv?
Hloov DC hluav taws xob hloov hluav taws xob yog DC hluav taws xob transformer nrog hloov hlab. Thaum tsim DC fais fab khoom muaj hluav taws xob, ntxiv rau kev hloov pauv thiab cov khoom siv hluav taws xob, uas feem ntau yog cov khoom siv hluav taws xob thiab zaus ua haujlwm siab.
DC hluav taws xob hloov pauv, hloov DC transformer, thiab hloov lub raj ua ke oscillator, uas modulates lub tswv yim dc voltage rau hauv cov mem tes high-zaus dc voltage. Hauv kev tsim kho ntawm Flyback DC voj voog, hloov pauv hloov hluav taws xob hauv lub zog hluav taws xob, thiab tso nws thaum hloov raj muab tua. Hauv kev tsim ntawm lub zog DC cov khoom siv hluav taws xob hauv ntej DC, thaum lub tshuab hloov hluav taws xob tig rau, thiab lub zog khaws cia hauv lub zog cia Inductor.
Thaum hloov lub raj muab tua, lub zog cia hauv inductor yuav txuas ntxiv mus xa cov khoom tam sim no rau lub nra. Lub tswv yim DC-DC cov khoom siv hluav taws xob muab hluav taws xob hloov pauv mus ua ntau yam tsawg voltages.
Cov kev teeb tsa yooj yim ntawm DC Switching Transformer yog cov ntaub ntawv tseem ceeb ntawm cov ntaub ntawv sib nqus, cov khoom siv hlau, thiab cov khoom siv rwb thaiv tsev ua cov kev hloov pauv.
Cov khoom siv sib nqus: cov khoom sib nqus siv nyob rau hauv hloov pauv hloov pauv yog mos ferrite, uas tuaj yeem faib ua ob hom thiab siv tau ntau: mnzn thiab nizn. Tus qub tau muaj kev sib nqus siab permeability thiab siab siab muaj kev sib nqus ntawm qhov tsis muaj zog rau qhov nruab nrab rau cov khoom nruab nrab, thiab muaj cov txiaj ntsig poob hauv cov ntau zaus. Sib nqus cores tuaj nyob rau hauv ntau hom, xws li EI hom, e ntaus, EC hom, thiab lwm yam xov hlau. Enamel hlau: feem ntau yog siv rau cua tshuab hluav taws xob me me. Enamel hlau suav nrog cov hlau muaj zog polyester ci (QZ) thiab Polyurethane
Raws li cov tuab ntawm txheej, nws tuaj yeem faib ua hom 1 (nyias txheej txheej) thiab hom 2 (hom txheej tuab). Cov txheej txheem rwb thaiv tsev qub yog lub tshuab cua sov tiv thaiv polyurethane uas tau mus txog 60kv / mm, lub zog ntawm tus kheej-nplaum thiab tus kheej soldering cov khoom (380 degree c). Siab rhiab cov ntaub nplaum tuaj yeem raug Welded ncaj qha tsis muaj kev ua yeeb yaj kiab cov xim pleev xim, thiab cov kab xev insulating, thiab lub zog hluav taws xob muaj zog.
Kev faib tawm thiab tsis hloov DC hluav taws xob hloov pauv DC hluav taws xob hloov DC hluav taws xob hloov pauv. Lub hauv paus ntsiab lus thiab cov qauv ntawm ob lub hloov DC transformers sib txawv. Cov tswv yim DC cov khoom siv DC hluav taws xob voltage ntawm DC Transformer yog Unipolar pulse, uas tau muab faib ua cov khoom siv hluav taws xob tawm. Ntawm qhov tod tes, DC cov lus qhia voltage ntawm DC transformer nrog ob qhov kev paub zoo yog bipolar pulse, feem ntau bipolar. MEM NTSEM DC HWJ HWJ HWJ HWJ XEEB VEEM VIBPERAGE.
