Cov ntsiab cai thiab cov yam ntxwv ntawm kev tiv thaiv Circuit Court nyob rau hauv Switching Fais Fab Khoom
Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, kev sib raug zoo ntawm cov khoom siv hluav taws xob hluav taws xob thiab tib neeg txoj haujlwm thiab lub neej tau dhau los ua ze, thiab cov khoom siv hluav taws xob tsis tuaj yeem ua yam tsis muaj lub zog siv hluav taws xob. Yog li, DC hloov cov khoom siv hluav taws xob tau ua lub luag haujlwm tseem ceeb thiab tau nkag mus rau ntau yam khoom siv hluav taws xob thiab hluav taws xob. Cov khoom siv hluav taws xob hloov hluav taws xob tau siv dav hauv cov kev pab cuam - tswj cov keyboards, kev sib txuas lus, cov khoom siv hluav taws xob tshawb pom hluav taws xob, tswj cov khoom siv hluav taws xob, thiab lwm yam. Tib lub sijhawm, nrog rau kev txhim kho ntawm ntau yam siab - thev naus laus zis, suav nrog siab - zaus hloov tshuab, kev siv tshuab muag muag, lub zog hloov hluav taws xob kho tshuab, synchronous technology, thiab lwm yam. muab cov cuab yeej siv niaj hnub ua ntej, muab ntau qhov chaw tsim kho rau DC hloov hluav taws xob khoom siv. Txawm li cas los xij, vim qhov nyuaj ntawm kev tswj Circuit Court nyob rau hauv cov khoom siv hluav taws xob hloov hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv sib xyaw ua ke muaj qhov tsis zoo rau hluav taws xob thiab thermal shocks, uas ua rau muaj kev cuam tshuam loj rau cov neeg siv thaum siv. Txhawm rau tiv thaiv lub zog hloov hluav taws xob nws tus kheej thiab cov khoom thauj, raws li cov hauv paus ntsiab lus thiab cov yam ntxwv ntawm DC hloov hluav taws xob, kev tiv thaiv hluav taws xob, kev tiv thaiv overcurrent, tiv thaiv overvoltage, thiab cov hluav taws xob pib tiv thaiv hluav taws xob tau tsim.
DC switching fais fab mov muaj xws li ib qho input, ib qho kev hloov hluav taws xob, ib qhov tso zis, thiab ib feem tswj. Lub zog hloov dua siab tshiab yog qhov tseem ceeb ntawm kev hloov hluav taws xob, uas ua haujlwm siab - zaus chopping ntawm DC tsis ruaj khov thiab ua tiav qhov yuav tsum tau hloov dua siab tshiab rau cov zis. Nws yog tsim los ntawm kev hloov pauv transistor thiab siab - zaus transformer. Daim duab 1 qhia txog schematic thiab sib npaug schematic daim duab ntawm DC switching fais fab mov, uas muaj ib tug tag nrho yoj rectifier, ib tug switching tube V, ib tug excitation teeb liab, ib tug freewheeling diode Vp, lub zog cia inductor, thiab ib tug filtering capacitor C. Qhov tseeb, qhov tseem ceeb ntawm ib tug DC transformer fais fab mov yog
Txhawm rau ua kom tau raws li qhov xav tau ntawm cov neeg siv, qhov hloov pauv loj hloov hluav taws xob cov chaw tsim khoom hauv tsev thiab txawv teb chaws tau cog lus rau synchronously tsim cov khoom siv ntse tshiab, tshwj xeeb tshaj yog los ntawm kev txhim kho qhov poob ntawm cov khoom siv hluav taws xob sib nqus thiab nce cov cuab yeej siv hluav taws xob ferrite (Mn Zn) cov ntaub ntawv los txhim kho kev sib nqus kev ua tau zoo ntawm cov frequencies thiab siab sib nqus flux densities. Nyob rau tib lub sijhawm, daim ntawv thov ntawm SMT thev naus laus zis tau ua kom muaj kev vam meej hauv cov khoom siv hluav taws xob hloov pauv, npaj cov khoom ntawm ob sab ntawm lub rooj tsav xwm Circuit Court kom ntseeg tau tias lawv lub teeb yuag, me me, thiab nyias tsim. Yog li ntawd, txoj kev loj hlob ntawm DC hloov khoom siv hluav taws xob yog qhov muaj zaus, kev ntseeg siab, kev siv hluav taws xob tsawg, tsis tshua muaj suab nrov, tiv thaiv - cuam tshuam, thiab modularization.
