Yuav ua li cas yog lub diode tawg?

1, Direct manifestation ntawm diode puas
Tom qab lub diode puas lawm, qhov tshwm sim ncaj qha tshaj plaws yog kev hloov pauv hauv nws cov kev ua haujlwm hluav taws xob, uas feem ntau ua rau cov xwm txheej hauv qab no:
Qhib Circuit Court txhaum: Thaum lub diode tawg lossis qhib sab hauv, nws yuav ua tsis tau hluav taws xob. Qhov no txhais tau hais tias nyob rau hauv Circuit Court, tam sim no uas yuav tsum tau dhau los ntawm lub diode yog thaiv, ua rau lub Circuit Court malfunction. Nyob rau hauv lub rectifier Circuit Court, yog lub rectifier diode qhib circuited, nws yuav tsis muaj peev xwm hloov AC zog rau DC fais fab, ua rau lub hwj chim mov tsis ua hauj lwm zoo.
Kev txhaum luv luv: Hauv qhov sib piv rau qhov qhib Circuit Court, thaum lub voj voog luv luv tshwm sim hauv lub diode, nws yuav poob nws qhov kev coj ua tsis ncaj thiab ua bidirectional. Qhov no tuaj yeem ua rau muaj qhov txawv txav ntawm qhov tam sim no, uas tuaj yeem hlawv tawm ib puag ncig cov khoom lossis cov rooj sib tham. Nyob rau hauv lub voltage regulator Circuit Court, yog hais tias lub voltage regulator diode yog luv luv Circuit Court, nws yuav tsis muaj peev xwm muab ib tug ruaj khov tso zis voltage, uas yuav ua rau puas rau lwm yam khoom nyob rau hauv lub Circuit Court.
Kev ua tau zoo degradation: Tom qab ua haujlwm ntev, diodes yuav maj mam degrade vim kev laus, thermal stress, thiab lwm yam. Qhov no yog manifested raws li ib tug nce nyob rau hauv lub conduction voltage thiab to tam sim no ntawm lub diode. Txawm hais tias cov kev hloov no yuav tsis zoo li qhov qhib lossis luv luv Circuit Court, lawv tseem tuaj yeem cuam tshuam rau kev ruaj ntseg thiab kev ua haujlwm ntawm Circuit Court.
2, Qhov cuam tshuam ntawm diode puas ntawm cov tshuab hluav taws xob
Tom qab lub diode puas lawm, nws tsis tsuas yog cuam tshuam rau nws tus kheej kev ua haujlwm, tab sis kuj tseem muaj kev cuam tshuam loj heev rau tag nrho cov tshuab hluav taws xob:
Circuit malfunction: Raws li tau hais dhau los, diodes feem ntau ua lub luag haujlwm tseem ceeb hauv circuits, xws li rectification, voltage regulation, amplification, etc. Thaum lub diode puas lawm, cov haujlwm no tsis tuaj yeem ua tiav, ua rau tag nrho cov Circuit Court tsis ua haujlwm zoo. Piv txwv li, nyob rau hauv lub hwj chim Circuit Court, yog hais tias lub rectifier diode puas, lub hwj chim mov yuav tsis muaj peev xwm tso zis ruaj khov DC zog, uas yuav cuam tshuam rau lub hwj chim mov ntawm tag nrho cov khoom.
Cov khoom puas tsuaj: Yog tias lub diode puas lawm thiab tsis kuaj pom thiab hloov raws sijhawm, nws yuav ua rau muaj kev ua haujlwm tsis zoo. Piv txwv li, ib qho kev ua txhaum luv luv yuav ua rau muaj qhov txawv txav ntawm qhov tam sim no thiab hlawv tawm lwm yam khoom ntawm lub rooj tsav xwm Circuit Court; Qhov qhib Circuit Court txhaum yuav ua rau muaj qhov txawv txav ntawm qhov hluav taws xob hauv Circuit Court, ua rau cov khoom txuas nrog nws puas. Cov kev cuam tshuam ntawm cov saw hlau no tuaj yeem ua rau muaj kev puas tsuaj rau tag nrho cov cuab yeej.
Kev Nyab Xeeb Kev Nyab Xeeb: Qee zaum, kev puas tsuaj ntawm diode kuj tseem tuaj yeem ua rau muaj kev phom sij. Piv txwv li, nyob rau hauv high-voltage circuits, yog hais tias ib tug diode puas thiab ua rau ib tug txawv txav nyob rau hauv voltage nyob rau hauv lub Circuit Court, nws yuav ua rau muaj xwm txheej txaus ntshai xws li hluav taws xob poob siab thiab hluav taws. Yog li ntawd, kev saib xyuas tshwj xeeb yuav tsum tau them rau kev nyab xeeb thiab kev ntseeg siab ntawm diodes hauv high-voltage circuits.
Kev ua tau zoo degradation: Txawm hais tias qhov kev puas tsuaj ntawm diode tsis ncaj qha ua rau tsis ua haujlwm lossis cov khoom siv puas tsuaj, nws tseem tuaj yeem ua rau poob qis hauv kev ua haujlwm tag nrho. Piv txwv li, nyob rau hauv ib tug amplification Circuit Court, yog hais tias qhov kev ua tau zoo ntawm amplification diode deteriorates, nws yuav ua rau muaj teeb meem xws li txo amplification factor thiab muaj zog distortion. Txawm hais tias cov teeb meem no tsis tuaj yeem ua rau lub cuab yeej ua haujlwm tsis zoo tam sim ntawd, lawv tuaj yeem cuam tshuam rau kev ua haujlwm thiab cov neeg siv kev paub ntawm lub cuab yeej.
3, Kev tiv thaiv thiab kev tiv thaiv kev ntsuas
Txhawm rau zam qhov tshwm sim tsis zoo ntawm diode kev puas tsuaj, peb tuaj yeem siv cov kev tiv thaiv thiab teb cov lus teb hauv qab no:
Kev xaiv tsim nyog: Thaum xaiv diodes, kev xaiv tsim nyog yuav tsum tau ua raws li cov kev cai tshwj xeeb ntawm lub voj voog, xws li kev khiav hauj lwm voltage, tam sim no, zaus, thiab lwm yam. Xyuas kom meej tias cov diode xaiv tau raws li qhov yuav tsum tau ua ntawm Circuit Court thiab muaj qee qhov npoo.
Thaum tshav kub kub dissipation tsim: Lub diode generates ib tug npaum li cas ntawm tshav kub thaum ua hauj lwm. Yog tias cov cua sov dissipation tsis zoo, nws yuav ua rau nws cov txheej txheem kev laus. Yog li ntawd, thaum tsim cov circuits, cov teeb meem kub dissipation yuav tsum tau txiav txim siab tag nrho thiab cov kev ntsuas kub dissipation zoo (xws li cov dab dej kub, kiv cua, thiab lwm yam) yuav tsum tau ua.
Kev kuaj thiab kev saib xyuas tsis tu ncua: Rau cov khoom siv hluav taws xob uas ua haujlwm tau ntev, yuav tsum tau ua raws li kev sim thiab kev saib xyuas. Los ntawm kev kuaj xyuas cov hluav taws xob ua haujlwm ntawm diodes (xws li conduction voltage, to tam sim no, thiab lwm yam), cov khoom puas tuaj yeem kuaj pom thiab hloov tam sim ntawd.
Kev tiv thaiv kev ntsuas: Txhim kho overcurrent, overvoltage thiab lwm yam kev tiv thaiv hluav taws xob hauv Circuit Court kom tiv thaiv diode puas vim overload, overvoltage thiab lwm yam laj thawj. Cov kev tiv thaiv no tuaj yeem txhim kho kev ntseeg tau thiab kev nyab xeeb ntawm lub voj voog.
