Hloov fais fab mov module qhia hloov fais fab mov module DC Chopper
Cov lus qhia luv luv
Hloov cov khoom siv hluav taws xob tuaj yeem muab faib ua ob pawg: AC / DC thiab DC / DC. DC / DC conterters tau tam sim no tau modularized, thiab tsim kev siv tshuab thiab cov txheej txheem ntau lawm thiab qauv sib txawv, thiab tau raug lees paub los ntawm cov neeg siv. Txawm li cas los xij, qhov teeb meem ntawm AC / DC, vim nws tus kheej cov yam ntxwv, ntsib cov teeb meem nyuaj thiab cov txheej txheem kev tsim qauv hauv cov txheej txheem ntawm kev teeb meem.
dc ntov
DC / DC hloov dua siab tshiab yog cov txheej txheem ntawm kev hloov cov dc voltage rau hauv kev sib txawv dc voltage, tseem hu ua dc chopping. Muaj ob hom kev ua haujlwm ntawm tus pas dej dav dav: ib qho yog qhov tsis hloov pauv hloov thiab TUJ yog qhov tsis hloov pauv thiab TS tau hloov pauv (nquag cuam tshuam (nquag siv kev cuam tshuam). Lub voj voog tshwj xeeb tau muab faib ua cov hauv qab no:
(1) buck lub voj voog - ib kauj ruam-nqes chopper uas cov khoom siv nruab nrab hluav taws xob oo yog qis dua cov tswv yim voltage UI thiab muaj tib lub polarity.
(2) Boose Circuit Court - kev txhawb nqa Chopper uas cov zis nruab nrab voltage o yog ntau dua cov lus qhia voltage UI thiab muaj tib lub polarity.
(3) Buck Boost Circuit Court - ib kauj ruam-down los yog cov khoom siv roj hluav taws xob theem siab yog ntau dua lossis tsawg dua li cov lus qhia hluav taws xob UI, nrog kev sib txuas lus polarity thiab sab nrauv.
(4) CUK Circuit Court - Kauj Ruam lossis Ceg Chopper, uas tsim cov lus qhia nruab nrab ntawm cov lus tshaj plaws lossis tsawg dua li cov lus qhia voltage thiab muaj peev xwm sib kis.
AC / DC
AC / DC hloov dua siab tshiab yog cov txheej txheem ntawm kev hloov pauv hloov tam sim no rau hauv qhov tam sim no ncaj qha, thiab lub zog khiav tuaj yeem yog BIDRIRECTIONAL. Lub hwj chim ntws los ntawm lub zog hluav taws xob rau lub nra yog hu ua "Rectification", thiab lub zog ntws los ntawm lub thauj mus los mus rau lub hauv paus yog hu ua "inverter". Cov tswv yim ntawm AC / DC hloov dua yog 50 / 60Hz AC lub zog, uas yuav tsum tau ua rectified thiab lim. Yog li ntawd, ib qho hluav taws xob loj loj capacitor yog qhov tseem ceeb. Nyob rau tib lub sijhawm, vim yog cov qauv kev nyab xeeb (xws li ul, CCE, thiab lwm yam) thiab tsim kho cov miniaturization ntawm AC / DC cov khoom siv fais fab. Ib qho ntxiv, vim muaj cov siab tshaj plaws, kev siv siab ntau, thiab cov teeb meem nyuaj rau kev daws teeb meem hauv, Rau tib lub laj thawj, cov kev ntsuas siab thiab cov qauv tsim kho kom zoo ntxiv kom ua tiav cov qauv siv hluav taws xob ua kom tiav rau kev ua haujlwm zoo rau kev ua haujlwm zoo.
AC / DC hloov dua siab tuaj yeem muab faib ua ib nrab yoj Circuit Court thiab Wave Wave Circuit Court raws li txoj kev hlau ntawm Circuit Court. Raws li tus naj npawb ntawm cov theem fais fab, nws tuaj yeem faib ua ib theem, peb-theem, thiab ntau theem. Raws li cov haujlwm ua haujlwm ntawm Circuit Court, nws tuaj yeem muab faib ua plaub,
