Yuav ua li cas ua kom cov haujlwm ruaj khov ntawm cov khoom siv hluav taws xob nrog dodes?

1, cov ntsiab cai yooj yim thiab cov yam ntxwv ntawm dodes
Ib qho Diode, tseem hu ua tus semiconductor diode, yog lub cuab yeej semiconduct nrog ob electrodes (anode thiab cathode). Nws cov yam ntxwv uas tsis paub tseeb yog unidirectional conduction, uas tso cai rau tam sim no kom dhau tsuas yog hauv ib qho kev taw qhia. Cov yam ntxwv no ua rau kev ua haujlwm zoo rau kev ua haujlwm hauv cov khoom siv hluav taws xob, xws li siv cov khoom siv hluav taws xob, ntsuas hluav taws xob, hloov chaw, thiab kev tiv thaiv.
2, Daim ntawv thov ntawm dodes hauv rectification
Rectification yog cov txheej txheem ntawm kev hloov pauv hloov tam sim no mus rau hauv qhov tam sim no. Hauv cov khoom siv hluav taws xob, AC fais fab feem ntau yuav tsum hloov dua siab tshiab rau DC lub zog rau kev siv Circuit Court. Diode Rectifier yog qhov tseem ceeb rau ua tiav qhov kev hloov dua siab tshiab no. Piv txwv li, hauv tus choj ntsuas hluav taws xob, plaub dodes tsim tus qauv choj, uas tuaj yeem hloov kho ib nrab ntawm DC lub zog, ntsig txog, yog li tau txais cov pulsating DC lub zog. Los ntawm kev lim dej txuas ntxiv, lub DC lub zog tuaj yeem ua tau zoo ntxiv kom tau txais DC tso zis ruaj khov. Tus txheej txheem no ua kom ntseeg tau tias cov khoom siv hluav taws xob no tuaj yeem tau txais DC lub zog loj thiab ua haujlwm ruaj khov.
3, Daim ntawv thov ntawm diodes nyob rau hauv voltage kev cai
Voltage tshem tawm yog hais txog kev hloov pauv ntawm cov lus qhia voltage hloov mus rau qhov ruaj khov voltage. Lub zog ruaj khov hluav taws xob voltage yog qhov tseem ceeb rau kev ua haujlwm ib txwm muaj ntawm cov khoom siv hluav taws xob. Tus Diode Regulator tuaj yeem muab cov kev siv hluav taws xob ruaj khov los ntawm kev siv cov yam ntxwv ua los yog zener ua rau muaj kev cuam tshuam ntawm dodes. Thaum cov tswv yim voltage nce, cov voltage regulator Diode kev nqus ntau dhau tam sim no los tswj hwm qhov ruaj khov ntawm cov zis hluav taws xob. Tus txheej txheem no ua kom ntseeg tau tias khoom siv hluav taws xob tseem muaj zog txawm tias thaum lub zog hluav taws xob hloov pauv.
4, daim ntawv thov ntawm diodes nyob rau hauv kev tiv thaiv
Cov khoom siv hluav taws xob yuav pom ntau yam kev txawv txav hauv ntau lub sijhawm ua haujlwm, dhau los yog qhov txawv txav, thiab lwm yam yuav ua rau cov khoom siv hluav taws xob. Diodes ua si ib lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev voj voog. Piv txwv li, rov qab ntsuas cov kev ntsuas (xws li cov khoom siv hluav taws xob rov qab) tuaj yeem nqus cov kab hluav taws xob thiab tiv thaiv cov khoom siv hauv kev puas tsuaj vim yog overvoltage. Ib qho ntxiv, thaum cov tam sim no dhau lawm, cov kev txwv tam sim no yuav txwv qhov ntau ntawm qhov tam sim no, yog li tiv thaiv kev puas tsuaj rau hauv lub voj voog tshwm sim los ntawm ntau tam sim no. Cov txheej txheem kev tiv thaiv ua kom ntseeg tau tias cov khoom siv hluav taws xob tseem tuaj yeem ua haujlwm muaj kev nyab xeeb hauv kev txawv txav.
5, Daim ntawv thov ntawm diodes hauv kev ua teeb liab
Ntxiv rau kev rectification, voltage kev tswj hwm, thiab kev tiv thaiv, diodes tseem ua lub luag haujlwm tseem ceeb hauv kev teeb liab. Piv txwv li, nyob rau hauv kev kuaj lub vojrees, diodes tuaj yeem ntes qis qis- zaus cov cim ntawm high- zaus teeb liab demaldulation. Hauv kev hloov pauv hloov pauv, diodes tuaj yeem siv los ua siab- ceev hloov cov ntsiab lus los tswj cov ntsiab lus ntawm / tawm ntawm Circuit Court. Tsis tas li ntawd, diodes tseem tuaj yeem siv los ua cov voj voog ua ntau, thiab cov khoom siv lim dej ua kom tau raws li cov khoom siv hluav taws xob.
6, xaiv thiab ntseeg tau ntawm dodes
Kev xaiv ntawm dodes yog qhov tseem ceeb rau kev ua haujlwm ruaj khov ntawm cov khoom siv hluav taws xob. Thaum xaiv, yam xws li cov kev ua tau zoo, ntim tsim, kev ua haujlwm thermal, thiab kev ntseeg tau ntawm cov diode yuav tsum tau txiav txim siab. Kev ua tau cov khoom tsis muaj xws li tom ntej Voltage tso, thim rov qab voltage, rov qab los ncaj qha rau kev ua haujlwm ntawm dodees hauv kev ncig. Daim ntawv ntim ntim yuav tsum tsim nyog rau kev teeb tsa thiab cua sov dissipation yuav tsum muaj ntawm cov Circuit Court Board. Lub thermal kev ua tau zoo yuav tsum xyuas kom meej tias daim diode tsis muaj overheat thaum ntev- kev ua haujlwm. Kev ntseeg tau muaj feem cuam tshuam nrog lub neej thiab kev ruaj khov ntawm tag nrho cov khoom siv hluav taws xob.
Tsis tas li ntawd, kev ntseeg tau ntawm diodees tseem yog qhov tseem ceeb hauv kev ua haujlwm ruaj khov ntawm cov khoom siv hluav taws xob. Kev kuaj mob kev ntseeg tau yooj yim, ntsuas kub, kom ntseeg tau tias qhov kev ntsuas kub, kom paub tseeb tias yuav ua haujlwm tsis tu ncua nyob hauv thaj chaw hnyav. Nyob rau tib lub sijhawm, qhov zoo ntawm cov ntaub ntawv raw thiab cov txheej txheem ntau lawm yuav tsum tau nruj me ntsis tswj tau thaum lub sijhawm muaj kev cia siab thiab kev ruaj khov ntawm dodes.
