Ob lub puck Circuit Court thiab boost Circuit Court yog ib qho tseem ceeb hauv Circuit Court tsim kho vajtse, tshwj xeeb tshaj yog rau cov ntseONUsthiab OLT cov khoom siv.VOICE ua haujlwm hauvONUtsim siv lub boost Circuit Court ncaj qha boost lub voltage thiab muab hwj chim rau sab nraud xov tooj.Txoj hauv kev zoo tshaj plaws kom nkag siab txog lub zog hluav taws xob yog kom nkag siab tag nrho cov voltage thiab tam sim no ntawm txhua qhov ntawm Circuit Court, ntsib qee qhov teeb meem tuaj yeem pom tseeb qhov teeb meem taw tes.Piv txwv li, yuav ua li cas thaum lub inductance nce?Yuav ua li cas thaum lub capacitance nce?Dab tsi yog qhov cuam tshuam ntawm kev ua haujlwm zaus?Tom ntej no, peb lub tuam txhab yuav piav qhia rau koj.
Ua ntej tshaj plaws, cia peb tham txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm BOOST Circuit Court: Hauv daim duab hauv qab no, MOS transistor yog qhov hloov.Ntev npaum li qhov ceev nrawm txaus (qhov hloov zaus yog siab txaus), lub sijhawm rau thiab tawm (lub sijhawm them thiab tawm) yog tswj tau zoo, thiab ua ke nrog cov zis lim capacitor, lub hauv paus ruaj khov Vo tuaj yeem tau txais (lub suab. voltage ntawm peb cov ntseONUyog feem ntau 48V), uas yog qhov tso zis voltage.
Thaum lub qhov hluav taws xob qhib, lub inductor L yog hauv av, lub diode raug txiav tawm, thiab Vi tsub lub inductor L. Qhov voltage ntawm ob kawg ntawm inductor yog Vi (feem ntau yog 12V rauONUfais fab mov).Thaum qhov hloov pauv tsis ua haujlwm, vim tias qhov inductor L twb tau them thiab muaj tam sim no ntws los ntawm nws, tam sim no ntawm ob qho kawg ntawm inductor tsis tuaj yeem hloov pauv tam sim ntawd.Yog li ntawd, ib tug voltage yuav induced los ua lub diode ntawm txoj cai coj.Cov zis voltage Vo yog tas li, thiab lub diode conduction voltage poob yog Vd, yog li qhov voltage ntawm sab xis kawg ntawm inductor yog Vo + Vd, thiab qhov voltage ntawm sab laug kawg ntawm inductor yog lub hwj chim input Vi.Qhov no yog lub zog hluav taws xob, yog li Vo + Vd> Vi, lub inductance raug tso tawm rau lub sijhawm no, muab lub zog rau lub nra, thiab them cov zis lim capacitor.

Cov zis voltage Vo yog tas li, thiab lub diode conduction voltage poob yog Vd, yog li qhov voltage ntawm sab xis kawg ntawm inductor yog Vo + Vd, thiab qhov voltage ntawm sab laug kawg ntawm inductor yog lub hwj chim input Vi.Qhov no yog lub zog hluav taws xob, yog li Vo + Vd> Vi, lub inductance raug tso tawm rau lub sijhawm no, muab lub zog rau lub nra, thiab them cov zis lim capacitor.
Cov saum toj no yog cov ntsiab lus luv luv ntawm BOOST Circuit Court, uas tuaj yeem ua tus siv rau txhua tus.Peb lub tuam txhab muaj ib pab neeg ua haujlwm muaj zog thiab tuaj yeem muab cov kev pabcuam tshaj lij rau cov neeg siv khoom.Tam sim no, peb lub tuam txhab muaj ntau yam khoom: ntseonu, kev sib txuas lus kho qhov muag module, optical fiber module, sfp optical module, olt khoom, Ethernet hloov thiab lwm yam khoom siv network.Yog tias koj xav tau, koj tuaj yeem nkag siab tob.
