Yuav ua li cas tiv thaiv rov qab tam sim no los ntawm diodees hauv kev sib txuas lus modules?

1, lub hauv paus ntsiab lus ntawm diode los tiv thaiv rov qab tam sim no
Tus Diode yog tsim los ntawm kev sib txuas nrog P - hom semiconductor thiab n}} tiction, uas muaj unidirectional conduction. Thaum twg rau pem hauv ntej voltage yog thov rau Diode, lub PN Junction santre, cov tshuab hluav taws xob mus rau ntawm lub P cheeb tsam, kev sib tw ua txoj hauv kev tam sim no thiab cov Diode ua; Thaum rov qab voltage yog thov, cov pn kev sib tw thiab cov ntaub ntawv muaj lub siab tseem pheej hmoo, nrog yuav luag tsis muaj qhov tam sim no dhau mus thiab cov diode muab tua. Los ntawm kev siv cov xeeb ceem no, ib tug Diode tau txuas nrog hauv lub zog cov tswv yim davhlau ya nyob twg los yog qhov tseem ceeb ntsuas kev xa tawm ntawm kev sib txuas lus module. Thaum lub zog polarity yog qhov tseeb, tus diode ua thiab tam sim no ntws ib txwm; Thaum cov neeg polarity ntawm lub zog fais fab tau thim rov qab, tiv thaiv kev txiav tawm, tiv thaiv kev rov qab los ntawm kev nkag mus rau hauv kev sib txuas lus module, yog li muab kev tiv thaiv.
2, daim ntawv thov ntawm sib txawv ntawm diodes hauv Anti Tiav Txuas
(1) Rectifier Attender Diode
Rectifier decondifier diodes yog qhov feem ntau siv hom kev tiv thaiv rov qab diodes. Nws tau qis tom ntej voltage poob thiab siab rov qab voltage, uas tuaj yeem ua tau raws li cov kev txuas rov qab los tiv thaiv kev sib txuas lus. Piv txwv li, 1N4007 yog ib qho Revice Rectifier Diode nrog kev thim rov qab ntau ntawm 1A, haum rau qee qhov qis} Fais Fab Sib Txuas Lus. Txawm li cas los xij, lub sijhawm rov qab rov qab los ntawm kev siv hluav taws xob rov qab zoo nkauj donges
(2) Scottky Diode
Schottky diodes paub txog lawv cov qis tshaj tawm cov hluav taws xob poob thiab hloov nrawm dua. Piv nrog rau kev siv hluav taws xob dones, schottky diodes muaj qis dua voltage tso, feem ntau ntawm 0.3V thiab 0.5v, uas yuav pab txo hwj chim zog. Nyob rau tib lub sijhawm, nws lub sijhawm rov qab luv luv, nyob rau theem ntawm Nanosecond theem, ua rau nws haum rau anti rov qab txuas cov ntawv thov hauv high- zaus sib txuas lus modules. Piv txwv li, 1N5819 yog ib feem ntau siv Scottky Diode tam sim no ntawm 1a thiab lub ncov roj ntxiv hluav taws xob ntawm 40V, siv nyob rau hauv ntau cov khoom sib txuas lus panable.
(3) Kev rov qab nrawm Diode
Lub vas nthiv rov qab ua ke ib qho zoo ua ke qee qhov zoo ntawm kev ntsuas hluav taws xob zoo tib yam diodes thiab schottky diodes. Nws muaj tsawg dua voltage thim thiab lub sijhawm rov qab rov qab los ntawm kaum ntawm nanoseconds mus rau ntau pua nanoseconds. Qhov rov qab tawg voltage ntawm kev rov qab nrawm dua diodes yog qhov tseem ceeb thiab tuaj yeem tiv taus loj rov qab voltage surges. Hauv qee qhov kev sib txuas lus sib txuas lus uas xav tau kev ua haujlwm siab, xws li kev sib txuas lus kev lag luam, thiab lwm yam, kev hloov pauv ceev dodes yog qhov kev xaiv zoo tshaj plaws.
3, Lub Circuit Court tsim ntaub ntawv
(1) Cov hwj huam yooj yim anti rov qab Circuit Court
Ntawm lub hwj chim tawm tswv yim xaus ntawm kev sib txuas lus module, ib qho diode tuaj yeem txuas nrog hauv cov koob kom ua tiav kev tiv thaiv kev tiv thaiv rov qab los. Piv txwv li, txuas lub davhlau ya nyob twg ntawm 1N4007 Diode mus rau qhov zoo ntawm lub zog hluav taws xob thiab lub davhlau ya nyob twg rau lub zog ntawm kev sib txuas lus hauv kev sib txuas lus ntawm kev sib txuas lus. Thaum lub zog polarity yog qhov tseeb, tus diode ua thiab cov khoom siv tam sim no muaj zog rau kev sib txuas lus module; Thaum lub zog polarity tau thim rov qab, cov diode txiav tawm, tiv thaiv kev rov qab tam sim no los ntawm kev nkag mus rau hauv kev sib txuas lus module. Qhov Circuit Court muaj cov qauv yooj yim thiab tus nqi qis, tab sis nws yuav ua rau muaj qee yam hluav taws xob nce, ua rau muaj kev txo me me.
(2) Choj Anti Rov Qab Circuit Court
Rau kev sib txuas lus modules uas xav tau Bidirectional fais fab mov lossis yog insensitive rau lub hwj chim polarity, tus choj Anti rov qab Circuit Court tuaj yeem siv tau. Lub Choj los tiv thaiv Circuit muaj plaub dodes, uas ua kom paub tseeb tias qhov kev hla kev tam sim no los ntawm kev sib txuas lus hauv kev sib txuas lus tsis hais txog kev sib txuas lus ntawm lub zog. Piv txwv li, ntawm lub hwj chim tswv yim ntawm lub wireless kev sib txuas lus module, uas muaj hwj chim sib txuas lus thaum lub zog txuas rau hauv kev sib txuas lus lossis thim rov qab. Qhov kom zoo dua ntawm Choj Anti rov qab yog tias nws tuaj yeem hloov kho cov qauv sib txawv, tab sis cov qauv Circuit Court yog qhov tseem ceeb thiab tus nqi siab.
(3) Kev thim rov qab Circuit Court nrog kev tiv thaiv kev tiv thaiv
Txhawm rau txhawm rau txhim kho kev ruaj ntseg ntawm kev sib txuas lus module, lwm cov khoom tiv thaiv tuaj yeem muab ntxiv rau cov kev thim rov qab Circuit Court. Piv txwv li, lub fuse yog txuas txuas rau hauv qab ntawm Diode. Thaum lub sij hawm luv luv los yog overcurrent tshwm sim, cov fuse melts, txiav tawm lub zog hluav taws xob thiab tiv thaiv kev sib txuas lus los ntawm kev puas tsuaj los ntawm kev puas tsuaj. Voltaint trolression Diode (TVs) nyob rau ntawm lub hwj chim hloov pauv ntawm cov kab hluav taws xob siab thiab ua rau nws tsis cuam tshuam nrog kev sib txuas lus module.
4, Kev ceev faj hauv daim ntawv thov
(1) Xaiv ntawm Diode tsis
Thaum xaiv Anti Rov Qab Diodes, nws yog qhov tsim nyog los xaiv cov tsis tsim nyog raws li qhov xav tau tiag tiag ntawm kev sib txuas lus module. Xav txog cov tsis muaj xws li qhov siab tshaj plaws tam sim no, rov qab tawg voltage, tom ntej Voltage poob, thiab rov qab lub sijhawm rov qab los ntawm Diode. Yog tias qhov nyiaj siab kawg yog qhov tseem ceeb tshaj plaws yog qhov me me, nws yuav ua rau diode overheating thiab puas; Qhov rov qab tawg qhov hluav taws xob hluav taws xob tsawg dhau rau nrog cov hluav taws xob rov qab nce ntawm lub zog hluav taws xob; Ntau dhau voltage poob peev tuaj yeem txo cov khoom siv fais fab hluav taws xob thiab cuam tshuam txog kev ua haujlwm ntawm kev sib txuas lus; Lub sijhawm rov qab los rov qab yuav ua rau muaj kev hloov pauv tseem ceeb hauv qhov siab - cov ntawv thov.
(2) Cov qauv cua sov dissipation
Thaum lub sijhawm ua haujlwm, diodes tsim ib qho nyiaj ntawm cov cua sov. Yog tias cov cua sov dissipation yog cov neeg pluag, nws tuaj yeem ua rau kub ntawm tus diode kom sawv, cuam tshuam nws txoj kev ua tau zoo thiab kav lub neej. Thaum tsim qauv kev sib txuas lus, nws yog qhov tsim nyog los xav txog cov cua sov dissipation ntawm dodes. Cov nyhuv cua sov dissipation ntawm dailes tuaj yeem txhim kho los ntawm kev ntxiv cov cua sov ntxiv, txhim kho qhov cua txias, thiab lwm txoj kev.
(3) Circuit Coutout
Kev nthuav dav Circuit Court puag kuj tseem muaj kev cuam tshuam tseem ceeb ntawm kev ua haujlwm ntawm Anti rov qab Circuit Court. Sim ua kom luv luv cov kab txuas ntawm Diode thiab kev sib txuas lus module kom ntau li ntau tau, txo qis ntawm txoj kab, thiab kev cuam tshuam ntawm cov cim kev cuam tshuam thiab hluav taws xob poob qis. Lub caij no, nws yog ib qho tseem ceeb kom tsis txhob muaj hluav taws xob cuam tshuam ntawm diodes thiab lwm yam.
(4) Kuaj thiab Siv Tau
Tom qab ua tiav cov Anti rov qab Circulul tsim, nruj kev xeem thiab kev txheeb xyuas cov ntawv pov thawj. Txhawm rau sim xws li muaj lub zog polarity registal xwm txheej, kuaj seb puas muaj peev xwm ua haujlwm tau zoo thiab seb puas muaj peev xwm tiv thaiv rov qab tam sim no. Nyob rau tib lub sijhawm, nws yog qhov tsim nyog los kuaj qhov kev ua tau zoo ntawm lub voj voog ruaj khov nyob rau hauv cov kev mob ib puag ncig ntau xws li huab cua sov thiab av noo.
