Siv dodes kom txo qis kev cuam tshuam lub suab nrov hauv TV lub zog hluav taws xob

1, lub suab nrov sib cuam tshuam cov peev txheej hauv TV Lub Hwj Chim
Kev cuam tshuam lub suab nrov hauv TV Fais Fab Pawg Feem ntau yog los ntawm cov hauv qab no:
Muab cov khoom siv hluav taws xob ntau
Rov qab suab nrov ntawm Rectifier Diode: thaum lub sijhawm hloov dua siab tshiab los hloov pauv, Rectifier Diode lub suab rov qab rov qab vim yog them nyiaj rau kev them nyiaj. Hom suab nrov no tseem tuaj yeem nthuav tawm los ntawm kev ncig thiab ua rau cuam tshuam kev cuam tshuam rau TV.
Electromagnetic cuam tshuam (EMI): Kev hloov siab kub zaus tam sim no thiab kev hloov pauv hauv TV lub rooj tsav xwm, uas nyob rau hauv lem tuaj yeem ua rau hluav taws xob cuam tshuam. Qhov kev cuam tshuam zoo li cas tsis cuam tshuam rau kev ua haujlwm ntawm lub this vis nws tus kheej, tab sis kuj tseem yuav ua rau cuam tshuam nrog cov khoom siv hluav taws xob.
2, lub luag haujlwm ntawm diodes hauv kev txo cov suab nrov kev cuam tshuam
Ua Semiconductor ntaus ntawv nrog Unidirectional conduction, diermes ua lub luag haujlwm tseem ceeb hauv kev txo cov suab hluav taws xob hauv TV. Tshwj xeeb, cov diodes feem ntau tsuas yog txo cov suab hluav taws xob tsis muaj suab nrov los ntawm cov hauv qab no:
Rectification muaj nuj nqi: Hauv cov hluav taws xob voj voog, dodes ua raws li kho cov ntsiab lus kom hloov pauv hloov tshiab tam sim no. Los ntawm kev tsim cov Rectifier Circuit Court Tsim Nyog, Qhov cuam tshuam ntawm AC Cheebtsam ntawm DC cov khoom tuaj yeem raug txo qis, yog li txo lub suab kev cuam tshuam nrog.
Lim ua haujlwm: Tom qab cov ntaub ntawv hluav taws xob, kev lim dej hauv Circuit Court yog feem ntau ntxiv kom du cov zis DC. Diode tuaj yeem ua ke nrog capacitors, inductors, thiab lwm yam los ua cov suab nrov thiab lim dej zoo, thiab txhim kho qhov ruaj ntseg, thiab kev txhim kho qhov ruaj ntseg, thiab kev txhim kho qhov ruaj ntseg, thiab kev txhim kho qhov ruaj ntseg, thiab kev txhim kho qhov ruaj ntseg, thiab kev txhim kho qhov ruaj ntseg, thiab kho kom ruaj khov ntawm lub zog.
Yam nyhuv limkow: Qee qhov xwm txheej, diodes tseem tuaj yeem ua cov khoom txwv kom txwv lub teeb liab ntawm qee yam. Qhov no pab tiv thaiv kom tsis txhob muaj teeb meem ntau dhau los ntawm kev puas tsuaj rau Circuit Court, thaum txo lub suab hluav taws xob cuam tshuam.
Suppressing lub suab rov qab rov qab: rau rectifier diodes, rov qab nrov dua lub suab nrov yog qhov tseem ceeb ntawm suab nrov. Los ntawm kev xaiv diodes nrog luv rov qab lub sijhawm rov qab los yog siv lwm cov kev siv tshuab, cov neeg hloov mus rov qab los tau zoo.
Electromagnetic tiv thaiv kev tiv thaiv thiab hauv Circuit Court tsim, tsim nyog siv hluav taws xob kev tiv thaiv thiab kev siv hluav taws xob tseem ceeb yog tias txo hluav taws xob hauv hluav taws xob. Kev ntim khoom thiab txheej txheem ntawm cov khoom xws li diodes yuav tsum txiav txim siab siv hluav taws xob compressomagnetic (EMC) yuav tsum txo cov kev tawm tsam ntawm hluav taws xob hluav taws xob.
3, Daim ntawv thov tshwj xeeb ntawm diodes hauv kev txo cov suab nrov kev cuam tshuam
Cov ntawv thov tshwj xeeb ntawm dodes nyob rau hauv kev txo cov suab nrov cuam tshuam hauv TV lub zog hluav taws xob suav nrog tab sis tsis txwv rau cov hauv qab no:
Rectifier Choj choj Circuit Court: Lub Rectifier Choj Circuit Court muaj plaub dodes thiab yog siv los hloov AC zog rau DC lub zog. Los ntawm kev tsim cov kev ntsuas thiab cov txheej txheem ntawm Rectifier Choj Tsim Nyog, qhov cuam tshuam ntawm AC ntawm DC cov khoom tuaj yeem raug txo kom, yog li txo lub suab kev cuam tshuam nrog.
Lim Circuit Circuit: Tom qab Rectifier Choj Circuit Court, lub lim Circuit Court yog feem ntau ntxiv rau du cov zis DC. Dailes tuaj yeem ua ke nrog capacitors, inductors, thiab lwm yam los tsim lub zog lim dej, thiab lwm yam suab nrov thiab ripple, txhim kho qhov ruaj ntseg, txhim kho qhov ruaj ntseg ntawm lub zog.
Cov Regulator Regulator Circuit Court: Hauv TV Fais Fab Lub Rooj Tsav Tsheb, Cov Regulage Regulator Circuit Court yog siv los tswj qhov ruaj khov ntawm cov zis hluav taws xob. Ib tug diode tuaj yeem yog ib qho tseem ceeb ntawm cov kev tswj hluav taws xob hauv lub ntsuas hluav taws xob, xws li Zener Diode. Los ntawm kev tsim qauv ntawm cov tsis muaj zog thiab cov txheej txheem ntawm cov hluav taws xob hluav taws xob tsim nyog tsim nyog, kev cuam tshuam kev cuam tshuam hluav taws xob tuaj yeem txo qis dua.
Kev tiv thaiv Circuit: Hauv TV Fais Fab, kev tiv thaiv kev tiv thaiv yog siv los tiv thaiv kev txawv txav xws li overcurrent thiab overvoltes los ntawm kev puas tsuaj rau Circuit Court. Diodes tuaj yeem siv tau ua ib qho tseem ceeb hauv kev tiv thaiv kev ua haujlwm, thiab lwm yam. Cov kev tiv thaiv kev nyab xeeb
Mos hloov cov thev naus laus zis: muag hloov kev siv thev naus laus zis yog cov txheej txheem uas txo lub suab nrov los ntawm kev tswj hwm tus txheej txheem hloov ntawm hloov. Hauv TV lub nkoj hluav taws xob, kev siv cov tshuab muag hloov pauv tuaj yeem ua rau muaj lub suab rov qab rov qab thiab hluav taws xob ntsuas hluav taws xob.
