Taw qhia rau Cov Ntsiab Lus Tseem Ceeb ntawm Kev Hloov Hluav Taws Xob
Nrog rau kev txhim kho lub zog hluav taws xob 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 yog nce zuj zus, thiab cov khoom siv hluav taws xob tsis tuaj yeem sib cais los ntawm cov khoom siv hluav taws xob muaj zog. Xyoo 1980s, lub tshuab hluav taws xob hluav taws xob tau hloov pauv tag nrho, thiab nws yog thawj zaug ua kom tiav kev hloov hluav taws xob ntawm cov khoos phis tawj. Nyob rau xyoo 1990, kev hloov hluav taws xob hloov pauv tau nkag mus rau ntau yam khoom siv hluav taws xob thiab hluav taws xob, thiab kev hloov hluav taws xob tau siv dav hauv kev tswj cov keyboards, kev sib txuas lus, cov khoom siv hluav taws xob tshawb pom hluav taws xob thiab cov khoom siv hluav taws xob tswj hluav taws xob, uas txuas ntxiv kev txhim kho sai ntawm switching fais fab mov technology. Hloov fais fab mov yog ib hom khoom siv hluav taws xob uas siv cov cuab yeej hluav taws xob niaj hnub siv hluav taws xob los tswj lub sij hawm sib piv ntawm kev hloov transistor rau thiab tawm thiab tswj cov zis hluav taws xob ruaj khov. Kev hloov hluav taws xob feem ntau yog tsim los ntawm pulse width modulation (PWM) tswj IC thiab MOSFET. Piv nrog rau cov khoom siv hluav taws xob linear, cov nqi hloov hluav taws xob thiab cov khoom siv hluav taws xob linear ob qho tib si nce ntxiv nrog kev nce ntawm cov zis hluav taws xob, tab sis lawv cov kev loj hlob txawv. Tus nqi ntawm cov khoom siv hluav taws xob linear yog siab dua li ntawm kev hloov hluav taws xob ntawm ib qho chaw tso zis hluav taws xob, uas yog tus nqi inversion point. Nrog rau kev txhim kho thiab kev tsim kho tshiab ntawm lub zog hluav taws xob thev naus laus zis, kev hloov pauv hluav taws xob thev naus laus zis tau hloov kho tas li, thiab qhov kev hloov pauv ntawm tus nqi no tau nce mus rau qhov qis-tso tawm hluav taws xob kawg, uas muab qhov chaw dav dav rau kev hloov hluav taws xob. High-frequency switching fais fab mov yog nws txoj kev loj hlob. High-frequency switching fais fab mov ua rau nws me me, thiab ua rau nws nkag mus rau ib tug dav daim ntawv thov teb, tshwj xeeb tshaj yog nyob rau hauv high-tech teb, uas txhawb lub miniaturization thiab portability ntawm high-tech khoom. Tsis tas li ntawd, kev txhim kho thiab kev siv ntawm kev hloov hluav taws xob yog qhov tseem ceeb hauv kev txuag hluav taws xob, txuag cov peev txheej thiab kev tiv thaiv ib puag ncig.
Switching fais fab mov yog tswj lub switching tube kom qhib thiab tawm ntawm kev kub ceev los ntawm Circuit Court. Nws converts ncaj qha tam sim no mus rau high-frequency alternating tam sim no thiab muab nws mus rau lub transformer rau transformation, yog li tsim ib los yog ntau pab pawg ntawm voltages xav tau! Yog vim li cas rau kev hloov mus rau Huawei lub high-frequency alternating tam sim no yog qhov ua tau zoo ntawm high-frequency alternating tam sim no nyob rau hauv transformer transformation Circuit Court yog ntau dua 50 Hz, yog li ntawd lub switching transformer yuav ua tau me me thiab tsis kub heev thaum ua hauj lwm! Tus nqi qis heev. Yog tias koj tsis tig 50 Hz mus rau qhov siab zaus, qhov hloov hluav taws xob hloov pauv tsis muaj nuj nqis! ! Hloov transformer tsis yog mysterious. Nws yog ib qho yooj yim transformer! Qhov no yog switching zog mov. Hloov fais fab mov tuaj yeem faib ua ob hom: cais thiab tsis cais. Hom kev rho tawm yuav tsum muaj qhov hloov pauv hloov pauv, tab sis hom tsis cais tawm yuav tsis tas muaj nws.
Nyob rau tib lub zog, qhov siab dua qhov hloov zaus, qhov ntim me me ntawm qhov hloov pauv hloov pauv, tab sis qhov siab dua qhov yuav tsum tau ua rau lub raj hloov pauv; Qhov thib ob ntawm kev hloov pauv hloov pauv tuaj yeem muaj ntau yam windings lossis ib qho winding muaj ntau cov kais dej kom tau txais cov khoom tsim nyog; Feem ntau, qee qhov kev tiv thaiv hluav taws xob yuav tsum tau ntxiv, xws li tsis muaj kev thauj khoom thiab kev tiv thaiv luv luv, txwv tsis pub cov khoom siv hluav taws xob hloov pauv yuav raug hlawv.
