Lub Circuit Court tshwj xeeb ntawm kev hloov hluav taws xob muaj xws li cov hauv qab no
(1) Buck Circuit Court - kauj ruam-down chopper, nws cov zis nruab nrab voltage Uo tsawg tshaj li qhov input voltage Ui, thiab polarity yog tib yam.
(2) Boost Circuit Court - boost chopper, nws cov zis nruab nrab voltage Uo yog ntau tshaj qhov input voltage Ui, thiab polarity yog tib yam.
(3) Buck-Boost Circuit Court - phaw los yog boost chopper, nws cov zis nruab nrab voltage Uo yog ntau dua los yog tsawg tshaj qhov input voltage Ui, polarity yog opposite, thiab inductance yog kis.
(4) Cuk Circuit Court - nplawm los yog boost chopper, nws cov zis nruab nrab voltage Uo yog ntau dua los yog tsawg tshaj qhov input voltage UI, lub polarity yog opposite, thiab lub capacitance kis tau tus mob. Niaj hnub no cov tshuab hloov pauv tau ua rau muaj txiaj ntsig zoo hauv DC / DC. Ntau yam ECI soft-switching DC / DC converters tsim thiab tsim los ntawm VICOR hauv Tebchaws Meskas muaj qhov tso zis ntau tshaj plaws ntawm 300W, 600W, 800W, thiab lwm yam, thiab cov khoom siv hluav taws xob sib xws yog (6, 2, 10, 17) W / cm3, qhov ua tau zoo yog (80-90) feem pua . Qhov tseeb high-frequency switching power module RM series siv cov cuab yeej siv hluav taws xob muag muag los ntawm Nyiv NemicLambda Tuam Txhab muaj qhov hloov pauv zaus ntawm (200 ~ 300) kHz thiab lub zog ceev ntawm 27 W / cm3. Nws siv lub synchronous rectifier (MOS-FET es tsis txhob Xiao Tetky diode), qhov ua tau zoo ntawm tag nrho cov Circuit Court yog nce mus rau 90 feem pua.
Kev hloov pauv AC / DC
AC / DC hloov dua siab tshiab yog hloov AC rau DC, thiab nws lub zog ntws tuaj yeem ua ob txoj kev. Lub hwj chim ntws los ntawm lub hwj chim qhov chaw mus rau lub load yog hu ua "rectification", thiab lub zog khiav ntawm lub load rov qab mus rau lub hwj chim qhov chaw yog hu ua "active inverter". Lub tswv yim ntawm AC / DC converter yog 50 / 60Hz alternating tam sim no. Vim hais tias nws yuav tsum tau kho thiab lim, ib qho loj lim capacitor yog qhov tseem ceeb. Nyob rau tib lub sijhawm, vim yog cov qauv kev nyab xeeb (xws li UL, CCEE, thiab lwm yam) thiab EMC cov lus qhia kev txwv (xws li IEC, FCC, CSA), AC input sab yuav tsum ntxiv EMC lim thiab siv cov khoom uas ua tau raws li cov qauv kev nyab xeeb, uas txwv qhov miniaturization ntawm AC / DC fais fab mov. Tsis tas li ntawd, vim muaj qhov siab zaus, qhov siab voltage, thiab tam sim no loj Qhov kev hloov pauv ua rau nws nyuaj dua los daws qhov teeb meem ntawm EMC electromagnetic compatibility, uas tseem tso siab rau cov kev xav tau siab rau kev tsim cov khoom siv hauv high-density installation circuits. Rau tib lub laj thawj, high-voltage thiab high-tam sim no keyboards nce lub zog noj thiab txwv AC / DC converter modularization txheej txheem, yog li nws yog ib qho tsim nyog yuav tsum tau txais kev siv hluav taws xob zoo tsim qauv tsim kom nws ua hauj lwm efficiency ncav cuag ib qho kev txaus siab.
Kev hloov pauv AC / DC tuaj yeem muab faib ua ib nrab-yoj Circuit Court thiab puv-yoj Circuit Court raws li txoj kev xaim ntawm lub voj voog. Raws li tus naj npawb ntawm cov theem fais fab, nws tuaj yeem muab faib ua ib theem, peb theem thiab ntau theem. Raws li kev ua haujlwm quadrant ntawm lub voj voog, nws tuaj yeem muab faib ua ib lub quadrant, ob lub quadrant, peb quadrant, thiab plaub quadrant.
