Cov ntsiab lus tseem ceeb ntawm Hloov Cov Khoom Siv Hluav Taws Xob
Nrog rau kev tsim hluav taws xob hluav taws xob thev naus laus zis, cov khoom siv hluav taws xob hluav taws xob hluav taws xob thiab cov neeg ua haujlwm, lub neej tau nce zuj zus, thiab cov khoom siv hluav taws xob tsis sib cais los ntawm cov khoom siv hluav taws xob txhim khu kev qha, mus rau hauv 80 lub computer fais fab mov kom ua tiav tag nrho cov kev paub ntawm kev hloov hluav taws xob, thawj. kom ua tiav lub khoos phis tawj lub zog hloov pauv, mus rau hauv 90's switching fais fab mov tau nkag mus rau ntau yam khoom siv hluav taws xob thiab hluav taws xob hauv thaj chaw ntawm kev sib pauv tswj kev sib txuas lus, kev sib txuas lus, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv tswj, thiab lwm yam. fais fab mov, ntau dua los txhawb txoj kev loj hlob sai ntawm kev hloov hluav taws xob siv tshuab. Nyob rau xyoo 1990, kev hloov hluav taws xob hloov pauv tau nkag mus rau hauv ntau yam khoom siv hluav taws xob thiab hluav taws xob, xws li kev tswj cov khoom siv hluav taws xob, kev sib txuas lus, cov khoom siv hluav taws xob ntsuas hluav taws xob, cov khoom siv hluav taws xob tswj hluav taws xob, thiab lwm yam. Cov khoom siv hluav taws xob hloov hluav taws xob tau siv dav, uas tau txhawb nqa. txoj kev loj hlob sai ntawm switching fais fab mov technology. Kev hloov pauv hluav taws xob yog siv cov cuab yeej hluav taws xob niaj hnub siv hluav taws xob, tswj kev hloov pauv hloov pauv hloov pauv ntawm lub sijhawm thiab lub sijhawm tawm, kom tswj tau qhov tso tawm hluav taws xob ruaj khov ntawm lub zog hluav taws xob, hloov hluav taws xob feem ntau yog los ntawm pulse width modulation (PWM) tswj IC thiab MOSFET muaj pes tsawg leeg. Hloov fais fab mov thiab linear fais fab mov piv rau tus nqi ntawm ob qho tib si nrog kev nce hauv cov zis hluav taws xob thiab kev loj hlob, tab sis tus nqi ntawm kev loj hlob ntawm ob qhov sib txawv. Linear fais fab mov nqi ntawm ib qho chaw tso zis hluav taws xob, tab sis siab tshaj qhov hloov hluav taws xob, qhov no tus nqi thim rov qab. Nrog rau txoj kev loj hlob ntawm lub hwj chim electronics technology thiab innovation, thiaj li hais tias lub switching fais fab mov technology nyob rau hauv tas li ntawd innovation, qhov no tus nqi reversal taw tes nce mus rau lub qis tso zis hwj chim kawg ntawm kev txav, uas muab ib tug ntau yam ntawm switching fais fab mov kev loj hlob qhov chaw. Switching fais fab mov high-frequency yog cov kev taw qhia ntawm nws txoj kev loj hlob, high-frequency switching fais fab mov miniaturisation, thiab hloov fais fab mov mus rau ib tug ntau yam ntawm kev siv, tshwj xeeb tshaj yog nyob rau hauv lub tshav pob ntawm high-tech thiab tshiab technology, txhawb lub miniaturization ntawm high-tech khoom. , lub teeb. Tsis tas li ntawd, kev txhim kho thiab kev siv ntawm kev hloov hluav taws xob hauv kev txuag hluav taws xob, kev txuag nyiaj thiab kev tiv thaiv ib puag ncig yog qhov tseem ceeb heev.
Switching fais fab mov yog tswj lub switching tube los ntawm Circuit Court mus nqa tawm high-ceev txoj kev pass thiab txiav-tawm. Qhov ncaj qha tam sim no rau hauv high-frequency alternating tam sim no muab rau lub transformer rau transformer, yog li tsim ib tug yuav tsum tau ib los yog ntau pab pawg ntawm voltage! Huawei high-frequency alternating tam sim no yog vim li cas high-frequency alternating tam sim no nyob rau hauv lub transformer transformer Circuit Court yog ntau dua li qhov efficiency ntawm 50HZ. Yog li qhov hloov pauv hloov pauv tuaj yeem ua rau me me, thiab kev ua haujlwm tsis kub heev! Tus nqi qis heev. Yog hais tias tsis yog 50HZ rau hauv siab zaus uas hloov fais fab mov tsis muaj nuj nqis! Hloov transformer tsis yog mysterious. Yog ib qho yooj yim transformer! Qhov no yog switching power supply. Hloov cov khoom siv hluav taws xob tuaj yeem muab faib ua qhov sib cais thiab tsis sib cais ob hom kev sib cais yuav tsum muaj qhov hloov pauv hloov pauv, thiab tsis cais tawm yuav tsis tas yuav muaj.
Nyob rau tib lub zog, qhov siab dua qhov hloov zaus, qhov me me ntawm qhov hloov pauv hloov pauv, tab sis qhov siab dua qhov yuav tsum tau ua ntawm lub raj hloov pauv; switching transformer muaj peev xwm muaj ntau tshaj ib tug thib ob winding los yog ib tug winding nrog ntau tshaj ib tug kais, thiaj li yuav tau txais qhov xav tau tso zis; feem ntau kuj yuav tsum tau ntxiv qee qhov kev tiv thaiv circuitry, xws li tsis muaj-load, luv-circuit thiab lwm yam kev tiv thaiv, txwv tsis pub nws yuav raug hlawv switching fais fab mov.
