Yuav ua li cas kom ua tiav txoj haujlwm ntawm diodes hauv kev tiv thaiv kev tsis vam khom khoom ntawm cov khoom sib txuas lus?

1. Qhov tseem ceeb ntawm Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Sib Txuas Lus
(1) Ua kom muaj kev sib txuas lus txuas ntxiv
Lub luag haujlwm tseem ceeb ntawm cov khoom siv sib txuas lus yog kom ua tiav cov ntaub ntawv kis thiab sib pauv. Lub zog ua haujlwm tsis ua haujlwm yuav ua rau kev sib txuas lus sib cuam tshuam sib cuam tshuam, cuam tshuam rau kev sib txuas lus ntawm ib txwm. Piv txwv li, hauv kev sib txuas lus ntawm lub tsheb txawb no, lub zog hluav taws xob tuaj yeem tiv thaiv cov neeg siv hauv thaj chaw ntawm kev hu xov tooj, nkag mus rau hauv Is Taws Nem, thiab lwm yam. Siv zog siv zog {{3} Tsis muaj kev tiv thaiv kev tiv thaiv tuaj yeem tswj hwm cov khoom siv sib txuas lus thaum lub sijhawm sib txuas lus luv luv, kom sib txuas lus luv luv ntawm kev sib txuas lus.
(2) tiv thaiv cov ntaub ntawv poob
Cov cuab yeej sib txuas lus tsim thiab khaws cov ntaub ntawv ntau dua thaum lub sijhawm cov neeg siv khoom, kev teeb tsa kev ua haujlwm tsis zoo yuav ua rau cov neeg siv tsis tau, ua rau poob rau cov neeg siv thiab ua haujlwm. Kev tiv thaiv fais fab kev tiv thaiv muaj peev xwm ua tau tias cov ntaub ntawv tseem ceeb tau txais kev cawmdim rau tsis tau raws sijhawm thaum lub zog tsis ua haujlwm, zam kev poob cov ntaub ntawv poob.
(3) Tiv Thaiv Cov Khoom Siv Ntaus
Sudden hluav taws xob muaj peev xwm ua rau voltage thiab hloov chaw tam sim no, ua rau puas tsuaj rau cov khoom kho vajtse ntawm cov khoom siv sib txuas lus. Piv txwv li, nws yuav ua rau kev puas tsuaj tseem ceeb xws li cov hluav taws xob modules thiab chips, nce cov nqi kho cov nqi thiab downtime. Lub Hwj Chim Kev Tiv Thaiv tuaj yeem cuam tshuam cov khoom no thiab paub meej txog kev nyab xeeb ntawm cov khoom siv khoom siv.
2. Txoj haujlwm ua tiav ntawm Diode hauv Kev Tiv Thaiv Kev Tiv Thaiv Kev Sib Txuas Lus
(1) Lub zog khaws cia thiab muab kev pab
Nyob rau hauv lub hwj huam - tawm kev tiv thaiv Circuit Court ntawm cov khoom sib txuas lus, diodes feem ntau siv nyob rau hauv conjunction nrog capacitors. Peev muaj capacitors muaj tus yam ntxwv ntawm lub zog cia. Thaum lub zog hluav taws xob yog qhov qub, capacitors raug them los ntawm diodes khaws ib qho nqi ntawm lub zog. Thaum lub zog muab lub zog poob zog, tus mechanacitor pib tawm, muab kev txhawb nqa lub hwj huam luv rau kev sib txuas lus. Cov Diods ua lub luag haujlwm tsis haum lub luag haujlwm hauv cov khoom siv hluav taws xob, kom tsis txhob them rau cov khoom siv hluav taws xob tsuas yog, thiab ua kom muaj peev xwm them rau hauv lub capacitor, thiab ua kom muaj peev xwm them rau hauv lub capacitor, thiab ua kom muaj peev xwm them rau hauv lub capacitor, thiab ua kom muaj peev xwm them rau cov khoom siv fais fab tuag thaum muaj peev xwm muab lub zog siv rau lub cuab yeej.
Xaiv cov diode uas tsim nyog: txhawm rau ua tiav lub zog cia hluav taws xob zoo thiab tso tawm, nws yog qhov tsim nyog los xaiv cov diode uas tsim nyog. Schottky diodes tau qis nraim rau pem hauv ntej conduction thiab nrawm hloov nrawm, uas tuaj yeem txo cov zog ntawm lub zog ntawm capitalicy. Nyob rau tib lub sijhawm, nws cov cwj pwm ceev ceev tuaj yeem paub tseeb tias lub capacitor tau raug txiav txim sai, cia cov catacitor kom muab lub zog siv rau lub sijhawm.
(2) teeb liab tiv thaiv thiab rho tawm
Tiv thaiv kev cuam tshuam rau cov phiajcim: hauv cov khoom sib txuas lus, cov paib uas muaj teeb meem me me. Instantaneous fais fab tuag yuav tsim hluav taws xob kev cuam tshuam hluav taws xob, cuam tshuam qhov zoo ntawm lub teeb liab. Diodes tuaj yeem siv los tsim cov teeb meem kev tiv thaiv teeb liab kev tiv thaiv kab ncig, cais cov cim rhiab ntawm cov khoom siv cuam tshuam. Piv txwv li, los ntawm kev sib txuas cov diodes hauv cov kab mob kis, tiv thaiv kom tsis txhob muaj lub hwj chim tsis ua haujlwm, thiab ua kom muaj kev ncaj ncees ntawm lub teeb liab.
Kev siv cov paib ntsuas: Hauv kev sib txuas lus powered los ntawm ntau qhov sib txawv ntawm lub zog sib txawv, uas yuav muaj kev cuam tshuam zoo rau lub teeb liab thaum lub zog nruab nrab. Los ntawm kev siv diodes rau cov teeb liab kev sib cais, cov khoom siv hluav taws xob sib txawv tuaj yeem raug cais los tiv thaiv cov cim kev cuam tshuam ntawm kev cuam tshuam ntawm kev cuam tshuam rau cov teeb meem. Piv txwv li, siv cov diode caiv lwm qhov nruab nrab ntawm cov hluav taws xob hluav taws xob thiab cov hluav taws xob hluav taws xob tuaj yeem tiv thaiv cov suab nrov ntawm cov suab nrov ntawm cov khoom sib cuam tshuam nrog kev ua haujlwm ib txwm ntawm analog circuits.
(3) voltage clamp thiab ruaj khov
Liming Overvoltage: Kev Tsim Kho Yuav tshwm sim thaum lub zog hluav taws xob, ua rau muaj kev puas tsuaj rau cov khoom siv sib txuas lus. Zener desies yuav siv tau rau voltage clamping. Thaum lub voltage ntau dua lawv qhov kev sib cav sib ceg, lub zenering Diode ua, clamping qhov kev sib tsoo ntawm lub zog hluav taws xob thiab tiv thaiv cov hluav taws xob tom qab los ntawm kev puas tsuaj los ntawm kev siv hluav taws xob. Piv txwv li, siv cov hluav taws xob hluav taws xob Diode ntawm lub zog hluav taws xob tuaj yeem tiv thaiv kev puas tsuaj rau sab hauv module thiab nti ntawm lub cuab yeej thaum lub zog tsis ua haujlwm.
Lub zog hluav taws xob: thaum lub zog hluav taws xob: thaum lub zog - tawm cov txheej txheem tiv thaiv, Capactrorchret-paug yuav ua rau cov hluav taws xob maj mam poob. Txhawm rau ua tus voltage tso rau smoother, ntau yam diodes thiab de resistors yuav siv tau los ua tus qauv hluav taws xob. Los ntawm xaiv cov lus ntawm diodes thiab resistors ceev ceev ntawm cov khoom siv voltage rau ib lub sijhawm ntawm lub sijhawm, muab kev txhawb nqa hluav taws xob ib ntus, muab cov khoom siv hluav taws xob ruaj khov rau lub sijhawm sib txuas lus.
(4) Tiv thaiv kom rov qab cov ntws rov qab
Tiv thaiv cov pob hluav taws xob hluav taws xob: hauv cov khoom sib txuas lus, cov fais fab modules feem ntau yuav tsum tau muab lub zog rau ntau lub zog. Thaum lub nra ua tsis zoo los yog poob hwj chim, rov qab tam sim no yuav tsim tawm, ua rau muaj kev puas tsuaj rau lub zog hluav taws xob. Cov DIode tuaj yeem txuas rau hauv cov kev sib txuas ntawm cov zis kawg ntawm lub zog hluav taws xob kom tiv thaiv rov qab los ntawm kev ntws mus rau hauv lub zog module thiab tiv thaiv nws txoj kev nyab xeeb.
Nco ntsoov ntaus ntawv tsim nyog: hauv kev sib txuas lus sib txuas lus ntawm ntau cov khoom siv, tej zaum yuav muaj hluav taws xob sib txuas ntawm cov khoom sib txawv. Thaum lub cuab yeej poob hwj chim, nws tuaj yeem tsim rov qab qhov tam sim no uas cuam tshuam txog kev ua haujlwm ib txwm ntawm lwm cov khoom siv. Los ntawm kev siv diodes ntawm cov kab kev sib txuas ntawm cov khoom siv, kev tawm ntawm cov kev thim rov qab tam sim no tuaj yeem tiv thaiv, kom muaj kev nyab xeeb ntawm tag nrho cov kev sib txuas lus.
3. Kev thov cov yam ntxwv ntawm ntau hom kev donges nyob rau hauv kev tiv thaiv kev tsis vam
(1) schottky diode
Schottky diodes muaj qhov zoo ntawm cov hluav taws xob voltage qis, nrawm hloov nrawm, thiab siab} cov yam ntxwv. Hauv kev tiv thaiv kev tiv thaiv tsis ua haujlwm, nws yog qhov haum rau cov xwm txheej uas yuav tsum tau teb nrawm thiab poob qis, xws li kev koom tes nrog kev ua tiav lub zog cia khoom thiab tso tawm. Nws txoj kev hloov nrawm nrawm tuaj yeem txo lub zog ntawm lub cev hluav taws xob thiab txhim kho cov txiaj ntsig ntawm kev tiv thaiv fais fab kev tiv thaiv.
(2) zener diode
Zener desies yog tsuas yog siv rau voltage clamping thiab stirilization. Nws tau mob siab yuam kev voltage thiab zoo qhov kub ruaj khov, uas tuaj yeem txwv qhov hluav taws xob tsis pub dhau lub zog tsis ua haujlwm thiab tiv thaiv kab ke tom ntej. Thaum xaiv lub chaw ntsuas hluav taws xob Diode, nws yog qhov tsim nyog los xaiv qhov kev tsim nyog tsim hluav taws xob thiab lub zog muaj zog raws li cov kev xav tau ntawm Circuit Court.
(3) Rectifier Attendier Diode
Rectifier decondifier diodes muaj siab rov qab voltage thiab muaj peev xwm nqa tau loj tam sim no. Hauv kev tiv thaiv kev tsis ua hauj lwm tsis muaj kev tiv thaiv, nws tuaj yeem siv los tiv thaiv kev rov qab ntws tam sim no thiab tiv thaiv cov hwj huam loj. Txawm hais tias nws hloov ceev nrawm yog qeeb, nws tseem tuaj yeem ua lub luag haujlwm tseem ceeb hauv qee qhov xwm txheej uas tsis xav tau.
