1. Tshooj lus
Nrog rau kev siv hluav taws xob thoob plaws ntawm cov khoom siv hluav taws xob xws li hloov cov khoom siv hluav taws xob xws li, hauv tsev thiab kev lag luam, tus tsis muaj zog hauv lub zog tau nce ntxiv. Thaum lub sijhawm ua haujlwm ntawm cov khoom siv hluav taws xob muaj zog, muaj teeb meem ntau ntawm cov khoom siv hluav taws xob, ua rau muaj teeb meem kev tiv thaiv hluav taws xob uas muaj kev phom sij ntawm kev nyab xeeb ntawm kev ua haujlwm fais fab ntawm lub zog kev nyab xeeb. Hauv kev pom cov teeb meem saum toj no, daim ntawv no sib xyaw ua ke ntawm kev sib raug zoo ntawm DC, thiab lub peev xwm kev sib raug zoo thiab cov peev txheej sib npaug, thiab tom qab ntawd tau txais cov nqi hluav taws xob ntau. Qhov tseeb ntawm kev xam cov txheej txheem tau txheeb xyuas los ntawm kev sim.
2. Cov qauv tseem ceeb ntawm Circuit Court thiab cov cai them nyiaj
Lub kaw lus tau txais ib peb {{-} theem plaub - xaim hluav taws xob qauv. DC sab midpoint tsis txuas nrog lub inductor. AC ib sab txuas nrog peb {{4 4}}}} theem fais fab mov los ntawm ib qho interface inductor. DC sab txuas nrog tus txhawb nqa capacitor kom tsis muaj kev phom sij thiab siv hluav taws xob txhawb nqa hluav taws xob.
3. Lub Tsheb Npav Hluav Taws Xob Tsim
3.1 Tsom xam cov tsheb npav hluav taws xob voltage muaj nqis
Txhawm rau ua tiav cov kev siv hluav taws xob tiav, lub zog siv hluav taws xob nquag yuav tsum ua kom cov zis hluav taws xob ntawm cov nqi hauv theem siab tshaj ntawm theem voltage ntawm ib sab. Thaum nruab nrab ntawm lub capacitor yog luv- cirtited rau sab hauv qhov chaw nyob hauv DC sab tuaj yeem tau los ntawm kev siv cov kab lus KVL hauv lub voj:
Cov theem voltage ntawm cov pej xeem faib network yog 220 v. Xav tias cov khoom siv hloov hluav taws xob thiab tsis quav ntsej txog kev sib raug zoo, cov theem hluav taws xob ncov siab yog:
Ex=110% * 220 * 2=342.
3.2 Kev tsom xam ntawm capacitory riplle tam sim no thiab capacitor poob
Lub zog pauv nruab nrab ntawm cov phiaj xwm thiab lub nra tsuas yog ua tiav los ntawm Busbar capac cap capactsance. Yog tias tus nqi capacitance kuj yog me me, lub voltage stabilization tsis tuaj yeem ua tiav, thiab cov voltage pulsation ntawm DC sab yog loj; Yog tias tus nqi muaj peev xwm loj dhau lawm, txawm hais tias nws muaj txiaj ntsig zoo ntxiv, uas ua rau muaj cua sov ntxiv, cuam tshuam rau lub neej ua haujlwm ntawm lub capacitor.
4. Kev sim ua tau zoo thiab tshuaj ntsuam xyuas
Tus qauv tau tsim hauv matlab / simulink simulation software, thiab cov simulation tsis tau teev raws li hauv qab no: Peb {}}}}}}}}}}}}}}}}}} €} hz; Peb {-}}}}}}}} mh, c {} mf; Lub taub lim inductance lf=2.5 mh ntawm APF thiab daim phiaj, DC sab voltage u dc capaccharitance 2 mf.
5.Cov
Daim ntawv no qhia txog cov txheej txheem tsim qauv ntawm DC sab capacitor tus nqi, thiab cov zis hluav taws xob muaj txiaj ntsig zoo dua thiab cov txiaj ntsig DC ntau dua thiab tus nqi yog qhov tsim nyog dua. Nws tseem tuaj yeem tsim qauv DC sab capacitor nyob rau hauv lub zog them rau lub zog sib txawv, tso cai ripple lossis DC sab teeb tsa tus nqi. Qhov kev sim tshawb pom qhov tseeb thiab ua tau zoo ntawm tus qauv tsim. Txoj kev tsim qauv tsim qauv thiab kev tsim kev lag luam engineering muaj qee qhov siv tseem ceeb rau kev tshawb fawb thiab kev siv cov chaw tsheb npav.
