Lub hwj chim rectification tivthaiv ua lub luag haujlwm tseem ceeb hauv lub zog cia qhov chaw vuam tshuab los ntawm kev hloov pauv tam sim no (AC) lub zog los ntawm cov khoom siv loj rau hauv qhov tam sim no (DC) lub zog tsim nyog rau them lub zog cia. Tsab ntawv xov xwm no muab cov ntsiab lus ntawm kev ua haujlwm thiab qhov tseem ceeb ntawm ntu kev kho hluav taws xob hauv lub zog cia qhov chaw vuam tshuab, qhia txog nws lub luag haujlwm hauv kev ua kom muaj txiaj ntsig zoo thiab txhim khu kev qha.
- Lub Hwj Chim Hloov Pauv: Lub hwj chim rectification seem yog lub luag hauj lwm rau hloov AC zog rau DC fais fab. Nws siv rectifier circuits, xws li diodes los yog thyristors, los kho cov AC voltage waveform, uas ua rau lub pulsating DC waveform. Qhov kev hloov dua siab tshiab no yog qhov tseem ceeb vim tias lub zog khaws cia feem ntau xav tau DC lub zog rau kev them nqi thiab kev ua haujlwm tawm.
- Kev tswj hluav taws xob: Ntxiv nrog rau kev hloov AC rau DC lub zog, lub zog kho hluav taws xob kuj tseem ua raws li kev cai voltage. Nws ua kom ntseeg tau tias qhov hloov kho DC tso zis hluav taws xob tseem nyob hauv qhov xav tau kom ua tau raws li qhov xav tau ntawm lub zog cia. Kev tswj hluav taws xob tau ua tiav los ntawm kev tswj cov txheej txheem, xws li cov lus tawm tswv yim circuits thiab voltage regulators, uas saib xyuas thiab kho cov zis voltage raws li.
- Filtering thiab Smoothing: Lub rectified DC waveform uas tsim los ntawm lub hwj chim rectification seem muaj undesirable ripple los yog fluctuations. Txhawm rau tshem tawm cov kev hloov pauv no thiab tau txais cov txiaj ntsig zoo ntawm DC, cov khoom siv lim thiab smoothing yog ua haujlwm. Capacitors thiab inductors feem ntau yog siv los lim tawm cov khoom siv ntau zaus thiab txo qhov hluav taws xob ripples, ua rau muaj kev ruaj khov thiab txuas ntxiv DC fais fab mov.
- Power Factor Correction (PFC): Kev siv hluav taws xob zoo yog qhov tseem ceeb ntawm lub zog cia qhov chaw vuam tshuab. Lub zog rectification seem feem ntau suav nrog cov tswv yim kho lub zog los txhim kho kev siv hluav taws xob thiab txo kev siv hluav taws xob. PFC circuits nquag kho lub zog qhov tseem ceeb los ntawm kev kho cov tswv yim tam sim no waveform, aligning nws nrog voltage waveform, thiab txo reactive zog noj.
- Kev ntseeg siab thiab kev nyab xeeb: Cov khoom siv hluav taws xob kho hluav taws xob suav nrog cov yam ntxwv ntawm kev nyab xeeb thiab kev tiv thaiv cov txheej txheem kom ntseeg tau tias kev ua haujlwm ruaj khov thiab nyab xeeb ntawm lub tshuab vuam. Kev tiv thaiv overvoltage, kev tiv thaiv overcurrent, thiab kev tiv thaiv luv luv yog siv los tiv thaiv cov khoom kho kom zoo thiab tiv thaiv kev puas tsuaj rau lub cev. Cov kev ntsuas kev nyab xeeb no ua rau muaj kev cia siab tag nrho thiab lub neej ntev ntawm cov khoom siv.
Lub zog rectification seem ua lub luag haujlwm tseem ceeb hauv lub zog cia qhov chaw vuam tshuab los ntawm kev hloov AC lub zog rau hauv kev tswj hwm thiab lim DC lub zog rau kev them nyiaj rau lub zog cia. Los ntawm kev ua haujlwm hloov hluav taws xob, kev tswj hluav taws xob, kev lim dej, thiab kev ua kom zoo, nrog rau kev siv lub zog hloov kho thiab kev nyab xeeb nta, ntu no ua kom muaj txiaj ntsig thiab txhim khu kev lag luam ntawm lub tshuab vuam. Cov neeg tsim khoom txuas ntxiv txhim kho lub zog kho thev naus laus zis txhawm rau txhim kho lub zog ua haujlwm, txhim kho lub zog zoo, thiab tswj hwm qib siab tshaj plaws ntawm kev nyab xeeb hauv lub zog cia qhov chaw vuam daim ntawv thov.
