I. Kev qhia lus
Choj Rectifiers (Rever Rectifiers) yog ib qho kev ua haujlwm tseem ceeb ntawm lub zog hluav taws xob, nws lub luag haujlwm tseem ceeb yog hloov dua tshiab (AC) rau hauv qhov tam sim no (DC). Nrog nws cov txiaj ntsig ntawm kev ua haujlwm siab, kev ruaj khov thiab cov qauv yooj yim, lub teb chaws rectifier tau siv dav hauv hluav taws xob, kev tswj hwm thiab lwm thaj chaw. Hauv daim ntawv no, tus ua hauj lwm cov cai thiab cov qauv ntawm choj loj yuav tau qhia nyob rau hauv kev nthuav dav, txhawm rau muab cov nyeem nrog cov kev nkag siab tob.
Ii. Ua haujlwm ua haujlwm ntawm Rectifier Rectifier
Lub hauv paus ntsiab lus ua haujlwm ntawm cov Rectifier Rectifier yog nyob ntawm Unidirectional conductivity ntawm Diode. Nws siv plaub diodes (D1, D1, D1) los ua ib qho chaw sib txuas ua raws li kev sib txuas tshwj xeeb (choj txuas) kom paub txog cov rectification ntawm lwm yam tam sim no.
Tshwj xeeb, thaum qhov zoo ib nrab -}} Lub lim tiam AC yog thov rau pem teb rectifier, thaum D2 d4 d4 dodes yog thim rov qab. Nyob rau lub sijhawm no, D1 d3 d3 d3 d3 d3 d3 d3 Nyob rau tib lub sijhawm, D2 thiab D4 d4 dodes cutoff, tsis koom nrog hauv kev coj ua.
Thaum qhov tsis zoo ib nrab -} lub lim tiam ntawm AC fais fab tuag, thaum D1 d4 thiab D3 d3 d3 d4 d3 d3 d3 d3 d3 d3 d3 d3 d3 d3 d3 d3 d3 d3 d3 d3 Nyob rau lub sijhawm no, D4 d4 dodes coj ua, thiab cov nyiaj rov qab los ntawm qhov tsis zoo ntawm lub zog ntawm lub zog hluav taws xob, sib sau txoj kev thim rov qab. Nyob rau tib lub sijhawm, D1 thiab D3 d3 diodes txiav tawm thiab tsis koom nrog hauv kev coj ua.
Los ntawm cov txheej txheem saum toj no, tus choj Rectifier paub tag nrho -}} Cov rotification ntawm AC fais fab. Seb lub AC fais fab muaj nyob hauv qhov zoo ib nrab hlis lossis cov hluav taws xob hauv lub zog tuaj yeem ntws rov qab mus rau lub zog hluav taws xob tsis zoo, tsim cov DC qhov ruaj khov.
III. Lub ntsiab ntawm lub choj rectifiers
Choj rectifiers tuaj yeem muab faib ua ntau hom raws li cov qauv sib txawv, cov haujlwm thiab cov cai qhia txog kev ua haujlwm. Cov hauv qab no yog ob peb hom Reverifiers:
Ib Leeg -}} theem ntsuas rectifier
Qhov tib {-}} theem theem choj choj yog qhov tseem ceeb tshaj plaws ntawm cov choj rectifier thiab nws tsuas yog haum rau ib leeg {1} {theem ac fais fab khoom. Ib qho ib qho -}}}} theem choj choj When a single-phase AC power source is applied to the rectifier, the bridge rectifier is able to realize full-wave rectification of AC power and output stable DC power.
Peb {-} theem theem kuaj choj
Peb {-}} theem theem choj yog haum rau peb - {theem ac fais fab khoom. Piv nrog ib qho -}}}}}}}}}}}}}}} ectification efficiency thiab me dua qhov ntsuas qhov ua haujlwm me me. Ib peb {-}} theem qib choj Thaum peb {{-}}}}}}}}}}}}}}}} {parse ac fais fab.
Thyristor -} tswj lub choj rectifier
SCUR CHAVE RECTIFIER yog ib hom ntawm cov choj rectifier nrog cov kev ua haujlwm ntawm lub cev muaj nuj nqi. Nws siv cov tshuaj kho kom zoo li keeb kwm, thiab tswj cov ntaub ntawv ntsuas hluav taws xob thiab tam sim no los ntawm kev tswj lub conduction kaum sab xis ntawm cov scr. SCURCH RECTIFier muaj qhov zoo ntawm kev kho cov zis hluav taws xob hluav taws xob, nrawm nrawm, thiab lwm yam.
Hloov Hloov Choj Rectifier
Hloov lub choj Rectifier yog lub choj rectifier uas siv cov hlab (xws li Mosfet, igbt, thiab lwm yam) rau Rectification. Nws tau txais siab siab siab - zaus hloov tshuab kom paub cov rectification ntawm kev tswj hwm ntawm- tawm ntawm hloov hlab. Hloov chaw choj Rectifier muaj qhov zoo me me, lub teeb yuag, muaj txiaj ntsig zoo, thiab yog qhov tsim nyog rau cov ntawv teev xwm txheej txheem thiab tsim nyog rau kev ua haujlwm siab thiab muaj kev ntsuas siab.
IV. Cov txiaj ntsig zoo thiab qhov tsis zoo ntawm cov neeg soj ntsuam choj
Choj rectifier muaj cov txiaj ntsig zoo hauv qab no:
Cov Rectification Heltimiency:Cov cheeb tsam rectifier tuaj yeem paub tag nrho - Cov Recification} Wave Recification ntawm AC Fais Fab, nrog rau cov kev ua tau zoo.
Cov zis ua tau zoo Wurgorm:Choj rectifier tso zis DC Tam Sim No WaveForm yog ruaj khov, pulsation me me pulseation.
Cov qauv yooj yim:Choj rectifier qauv yog yooj yim, siv tau yooj yim, yooj yim rau kev tsim thiab tswj hwm.
Txawm li cas los xij, tus choj Rectifier tseem muaj qee qhov tsis zoo:
Coob tus ntawm diodes:Cov Rectifier yuav tsum tau plaub donodes, uas nce tus nqi thiab txij nkawm kev nyuaj.
Loj Loj:Vim tias qhov xav tau rau plaub donies thiab tus qauv circuit Court, qhov loj me ntawm tus choj rectifier yog tus loj.
Cov teeb meem kub dissipation:Cov Rectifier yuav ua rau muaj qee qhov ntau npaum li cas ntawm cov cua sov hauv cov txheej txheem ua haujlwm, thiab yuav tsum tau siv cov cua sov dissipation ntsuas kom ntseeg tau tias ib txwm ua haujlwm.
V. Xaus
Tus Rectifier yog ib qho kev ntsuas hluav taws xob tseem ceeb nrog qhov zoo ntawm kev ua haujlwm siab, kev ruaj khov thiab cov qauv yooj yim. Nws siv tau plaub diodes los ua ib ncig ntawm Circuit Court raws li kev sib txuas lus tshwj xeeb (choj txuas) kom paub txog cov rectification ntawm lwm qhov tam sim no. Raws li cov qauv sib txawv, cov haujlwm thiab cov ntawv teev npe ntawm choj tuaj yeem muab faib ua ntau yam, peb {}} pital bitoriers thiab hloov mus kuaj tus choj rectifiers. Hauv kev siv cov kev siv, nws yog ib qho tsim nyog los xaiv hom kev xav tau ntawm choj choj raws li cov kev xav tau thiab paub txog qhov kev ua tau zoo thiab tau txais txiaj ntsig zoo tshaj plaws thiab cov txiaj ntsig.
