Yuav ua li cas siv Schottky diodes los txhim kho lub zog hluav taws xob ntawm cov khoom sib txuas lus?

1. Txheej txheem cej luam ntawm Scottky Diodes
(1) cov qauv thiab cov ntsiab cai
Schottky diode yog ib tug kub cab kuj tsim raws cov hlau semiconductor hlws ris. Tsis zoo li dog dig diodes, nws siv ib txheej ntawm nyias hlau sib tsoo rau hauv n}} hom doped cov ntaub ntawv los tsim cov hlau sib tshuam (m {{2 s hlws). Thaum mus rau tom ntej kev tsis ncaj ncees, cov hlau sab ntawv lub anode thiab cov semiconductor sab dhau los ua cov Cathode. Thaum xa tawm tam sim no dhau mus, SCHOTTKY DIEST tsuas xav tau 0.3-0.4 volts pib ua, thaum zoo downs xav tau 0.6-0.7 volts. Qhov no tsawg qis rau pem hauv ntej voltage tee cov yam ntxwv txo lub zog hluav taws xob tsim los ntawm schottky diiodes thaum lub sij hawm conduction.
(2) cov yam ntxwv zoo
Schottky diodes muaj qhov nrawm nrawm nrawm nrawm nrawm nrawm nrawm, txawm tias tsawg li ob peb nanoseconds. Cov xeeb ceem no tshwj xeeb yog qhov tshwj xeeb tshaj yog nyob rau hauv high- zaus circuences, raws li nws tuaj yeem ua rau nce hloov kho kev ua haujlwm zoo. Ib qho ntxiv, thim rov qab ntau ntawm schottky diodes feem ntau tsis pub dhau 50v. Txawm hais tias nws yog qhov qis dua li qhov tseem ceeb doneses, nws tuaj yeem ua tau raws li qhov yuav tsum muaj nyob hauv cov khoom siv hluav taws xob tsawg. Lub caij no, nws qis dua voltage poob thiab cov yam ntxwv tsis tshua muaj suab, ua rau nws muaj feem xyuam nyob rau hauv cov khoom siv sib txuas lus.
2. Daim ntawv thov ntawm schottky diiodes nyob rau hauv kev sib txuas lus fais fab khoom fais fab mov
(1) Rectification thov
Ntawm lub hwj chim tawm tswv yim xaus ntawm cov cuab yeej sib txuas lus, nws yog feem ntau yuav tsum tau hloov dua lwm txoj kev tam sim no kom ncaj qha tam sim no. Schottky diodes yuav siv tau ua kom tawm i reatiodes. Siv xov tooj txawb Chargers ua ib qho piv txwv, Schottky diodes tuaj yeem txo lub zog hluav taws xob hauv rectifier circuits. Piv nrog tsoos PN Junction Diodes Dark, qis dua rau yav tom ntej Piv txwv li, hauv lub xov tooj txawb charger nrog 5v, siv cov kev ua kom muaj zog ntxiv rau cov kev xav tau ua rau lub zog cua txias thiab ua rau muaj kev ntseeg tau thiab kev pabcuam lub neej ntawm lub charger.
(2) Flow Flow Daim Ntawv Thov
Cov khoom siv inductive feem ntau nyob rau hauv lub zog fais fab ntawm cov khoom sib txuas lus. Thaum qhov tam sim no nyob rau hauv lub inductor dheev cuam tshuam, rov qab electromotive zog yuav tsim tawm, uas yuav ua rau lwm cov khoom siv hauv Circuit Court. Schottky diodes tuaj yeem siv ua freewheet diodes los muab txoj kev tso tawm rau tam sim no hauv inductors. Nyob rau hauv lub cev muaj zog drary, schottky diodes tuaj yeem muab cov kev pab cuam sai sai thaum lub sijhawm ncua kev siv nyiaj thiab kev txhim kho kev ntseeg tau. Piv txwv li, hauv lub kiv cua tsav tsheb hluav taws ntawm wireless kev sib txuas lus hauv hluav taws xob thaum lub sij hawm lub sijhawm ua haujlwm hauv lub cev.
(3) Anti Cov Ntaub Ntawv Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv
Lub zog sib txuas lus ntawm cov khoom sib txuas lus yuav raug thim rov qab vim yog kev ua tsis ncaj ncees, uas tuaj yeem ua rau kev puas tsuaj loj rau sab hauv cov khoom siv. Schottky diodes yuav siv tau rau hauv kev tiv thaiv kev tiv thaiv los ntawm kev ntws mus rau hauv lub ntaus ntawv thaum lub zog hluav taws xob tau thim rov qab. Thaum lub zog hluav taws xob yog txuas nrog ib feem ntau, cov qauv Dirode ua thiab qhov tam sim no ntws ib txwm; Thaum lub zog hluav taws xob tau thim rov qab, SCHottky diode txiav tawm, tiv thaiv tam sim no los ntawm ntws mus rau hauv lub ntaus ntawv thiab tiv thaiv nws qhov kev nyab xeeb. Piv txwv li, hauv qee cov khoom siv sib txuas lus, Schottky diodes siv rau kev tiv thaiv kev puas tsuaj, uas tuaj yeem txhim kho cov cuab yeej kev ntseeg tau thiab cov neeg siv kev paub.
3. Cov Ntaub Ntawv Kev Ntsuam Xyuas Cov Ntaub Ntawv
(1) rooj plaub 1: Cov ntawv thov hauv xov tooj txawb chargers
Lub xov tooj lub xov tooj ntawm lub xov tooj txawb xov tooj tau hloov pauv kev sib tw nrog schottky diiodes nyob rau hauv thiaj li yuav txhim kho them nyiaj ua haujlwm. Tom qab kev sim ua tiag tiag, hloov pauv kev ua yeeb yam ntawm cov charger nce ntawm 80% mus rau 85% los ntawm kev siv schottky diodes. Ntawm kev tso zis lub zog ntawm 10W, cov cua sov tsim los ntawm cov hluav taws xob tau txo qis, txo lub nra rau lub zog thiab kev pabcuam lub neej ntawm lub charger. Nyob rau tib lub sijhawm, vim muaj kev txhim kho lub sijhawm ua haujlwm, lub sijhawm them nyiaj ntawm cov xov tooj ntawm tes tau kuj tau ua kom luv, coj cov neeg siv khoom zoo dua.
(2) rooj plaub 2: Kev thov cov khoom siv fais fab hauv cov chaw sib txuas lus wireless hauv paus
Qhov ruaj khov thiab ua haujlwm ntawm lub zog hluav taws xob tseem ceeb heev hauv kev sib txuas lus wireless wireless. Qee tus neeg teb xov tooj kev sib txuas lus tau tshaj tawm SCottky diodes rau kev ua kom zoo rau hauv lub zog ntawm cov chaw nres tsheb. Kev ua tau zoo ntawm lub hauv paus nres tsheb nres tsheb fais fab tau txhim kho los ntawm kev siv Schottky doundification, freethovery tiv thaiv ntawm lub zog Circuit Court. Hauv kev ua haujlwm tiag tiag, hluav taws xob siv ntawm cov chaw nres tsheb hluav taws xob hluav taws xob tau raug txo los ntawm lub zog hauv qab ntawm lub zog tsis ua haujlwm thiab txhim kho kev ntseeg tau ntawm cov kev sib txuas lus network.
4. Cov kev sib tw thiab cov kev daws teeb meem ntsib los ntawm cov ntawv thov
(1) sib tw
Txawm hais tias schottky diodes muaj ntau yam zoo, lawv kuj ntsib qee cov kev sib tw hauv cov ntawv thov fais fab rau cov khoom siv sib txuas lus. Firstly waster withstand voltage ntawm schottky diodes Thib ob, cov xau tam sim no ntawm schottky diodes yog tus muaj kev kub siab, qhov twg tuaj yeem nce ntxiv, uas yuav ua rau thermal khiav tawm thiab puas rau lub cuab yeej. Ib qho ntxiv, hluav taws xob ruaj khov thiab ntev - sij hawm reliatlility ntawm schottky diodes yog tsawg, xav tau kev ntsuas nruj thiab saib xyuas nruj thaum siv.
(2) daws
Txhawm rau hais qhov teeb meem ntawm cov thim rov qab witiorage, schottky diodes siv hluav taws xob tsim nyog thiab kev ua kom zoo, zam lawv siv hauv hluav taws xob ntau. Rau qhov teeb meem ntawm kev xau dej siab tam sim no, cua sov dissipation ntsuas tuaj yeem coj los txo qhov kev ua haujlwm kub ntawm lub cuab yeej, yog li txo lub to fration tam sim no. Lub caij no, thaum xaiv SCottky diodes, muaj feem thib ua ntej yuav muab rau cov kabmob qis tam sim no, thiab kev soj ntsuam nruj me nyuam. Txhawm rau kom txhim kho hluav taws xob ruaj khov thiab ntev- kev ntseeg tau, kev saib xyuas tsis tu ncua, thiab kev saib xyuas tsis tu ncua thiab daws cov teeb meem muaj peev xwm daws teeb meem.
