Yuav ua li cas ua raws kev tiv thaiv tam sim no rau dodes hauv cov khoom sib txuas lus?

1. Cov kev tsim txom ntawm kev thim rov qab rau cov khoom siv sib txuas lus
Rov qab tam sim no tuaj yeem ua rau muaj ntau yam phom sij rau cov khoom siv sib txuas lus. Nyob rau hauv lub zog hluav taws xob, rov qab tam sim no tej zaum yuav ua rau kev puas tsuaj rau lub zog module, cuam tshuam rau lub zog hluav taws xob ntawm cov khoom siv; Hauv kev sib kis tus mob sib kis, rov qab tam sim no tuaj yeem cuam tshuam nrog cov kev sib kis thiab txo kev sib txuas lus zoo; Hauv kev sib xyaw ua ke, rov qab rau cov transistors thiab lwm yam sab hauv lub nti, ua rau lub nti mus rau malfunction. Piv txwv li, hauv kev sib txuas lus yooj yim, yog tias lub zog hluav taws xob tau thim rov qab, thim rov qab tam sim no tuaj yeem hlawv cov hluav taws xob kev tswj hwm thiab cov khoom tseem ceeb, ua kom tag nrho cov module tsis tuaj yeem ua haujlwm zoo.
2. Lub hauv paus ntsiab lus ntawm Diode rov qab kev tiv thaiv tam sim no
(1) Unidirectional conduction cov yam ntxwv
Ib tug diode muaj unidirectional conduction, uas txhais tau tias thaum lub voltage rau ob qho kawg ntawm Diode, tus diode ua thiab tam sim no tuaj yeem dhau mus qeeb; Thaum rov qab voltage yog thov, Diode raug muab tua thiab qhov tam sim no yog yuav luag xoom. Los ntawm kev siv cov xeeb ceem no, diodes tuaj yeem txuas rau hauv cov kab hauv kab kev uas xav tau kev tiv thaiv. Thaum rov qab tam sim no tshwm sim, cov diode yuav tiv thaiv qhov tam sim no los ntawm kev hla dhau, yog kev tiv thaiv cov khoom sib txuas ntxiv hauv Circuit Course.
(2) rov qab ua txhaum cov yam ntxwv
Thaum rov qab voltage ntawm ib tug diode ncav cuag ib tus nqi, rov qab hloov tshwm sim. Txawm li cas los xij, cov kab mob rov qab tawg ntawm cov diises ntawm ntau hom thiab cov kev sib txawv. Qee qhov tshwj xeeb tshwj xeeb, xws li cov regage regulators, tuaj yeem tswj cov hluav taws xob ruaj khov thiab qhov ntau ntawm cov neeg rov qab los lawm, muab qee yam cuam tshuam. Txawm li cas los xij, nyob rau hauv rov qab kev tiv thaiv tam sim no, nws yog feem ntau yog ntshaw rau cov diode kom txiav ua ntej cov kev xa rov qab kom tsis txhob nkag mus rau lub xeev puas.
3. Kev siv txheej txheem ntawm Diode rov qab kev tiv thaiv tam sim no
(1) Xaiv
Xaiv cov diode uas tsim nyog yog tus yuam sij rau kev ua tiav kev tiv thaiv tam sim no. Nws yog ib qho tsim nyog los xav txog qhov tsis xws li lub rov qab tawg ua kom tawg, siab tshaj plaws, thiab tom ntej Voltage poob ntawm Diode. Lub Thawv rov qab tawg yuav tsum muaj ntau dua qhov kev thim rov qab ntau tshaj plaws uas tuaj yeem tshwm sim hauv Circuit Court; Qhov siab tshaj plaws rov qab tam sim no yuav tsum muaj peev xwm tiv taus qhov cuam tshuam ntawm kev rov qab tam sim no; Cov hluav taws xob rau pem hauv ntej yuav cuam tshuam rau kev ua tau zoo ntawm Circuit Court. Piv txwv li, hauv qis {{{{{{}}}} voltage sib txuas lus, schottky diodes nrog me rau pem hauv ntej voltage xa ​​tuaj yeem xaiv tau; Nyob rau hauv high - voltage voj voog, dailes nrog siab dua rov qab tawg voltage yuav tsum tau xaiv.
(2) Circuit Tsim Qauv
Hauv kev tsim Circuit Court, donges yuav tsum muaj kev txuas nrog rau hauv cov kab hauv Circuit Court uas xav tau kev tiv thaiv. Rau lub zog hluav taws xob kev ua haujlwm, diodes tuaj yeem txuas nyob rau hauv cov lus ntawm lub zog cov tswv yim los tiv thaiv rov qab los ntawm kev thim cov khoom sib txuas tam sim no; Rau cov paib kev sib kis, kev tiv thaiv Diode tuaj yeem ntxiv rau ntawm cov paib nkag thiab cov zis tsoos tsho. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau cov teeb meem kev sib txuas ntawm cov dide kom ntseeg tau tias nws txoj kev sib txuas rau pem hauv ntej zoo ib yam nrog cov kev taw qhia ib txwm muaj ntawm Circuit Court.
(3) Txhim kho thiab debugging
Thaum txhim kho diodes, nco ntsoov tias lawv tau sib txuas kom tsis txhob muaj kev sib tiv tauj. Thaum lub sij hawm debugging txheej txheem, kev tiv thaiv loj ntawm Diode tuaj yeem tshawb xyuas los ntawm kev sim ua kom rov qab tam sim no. Piv txwv li, siv cov khoom siv hluav taws xob hloov kho kom tau thim rov qab rau cov hluav taws xob, saib xyuas kom rov qab ua rau rov qab los ntawm kev hla dhau los thiab tiv thaiv Circuit Court tib yam.
4. Teeb meem thiab kev daws teeb meem hauv kev siv
(1) teeb meem: diode overheating
Thaum rov qab tam sim no yog loj, cov diode yuav raug puas vim yog cua sov. Txoj kev daws suav nrog kev xaiv Dailes nrog lub zog loj dua lossis ntxiv cov khoom siv kub disspipation xws li lub cua sov dissipation xws li lub cua sov dissipation xws li lub cua sov disset cuab yeej, kiv cua, thiab lwm yam.
(2) Qhov teeb meem: Takeage tam sim no ntawm Diode
Thaum ib qho Diode yog muab tua nyob rau hauv rov qab, yuav muaj ib qho to taub tam sim no. Yog hais tias lub towage tam sim no yog loj, nws yuav cuam tshuam rau txoj haujlwm ib txwm ntawm Circuit Court. Qhov cuam tshuam ntawm kev xau tam sim no tuaj yeem raug txo los ntawm kev xaiv zoo zoo diodes lossis txhim kho kev tsim hluav taws xob.
(3) teeb meem: diode teb kom ceev
Hauv qee qhov siab - Kev sib txuas lus ceev rau cov kev sib txuas lus, dodes yuav tsum muaj cov lus teb nrawm nrawm thiab muaj peev xwm tiv thaiv rov qab raws sijhawm. Koj tuaj yeem xaiv dodes nrog ceev hloov cov yam ntxwv, xws li kev rov qab nrawm dua.
