Yuav ua li cas ua desies ua teeb liab taw qhia kev tswj hwm hauv lub hwj chim sib koom?

, Lub cev ntawm lub cev ntawm unidirectional conductivity ntawm dodes
Cov qauv tseem ceeb ntawm Diode yog ib thaj chaw ua si, uas ua rau cov kev sib tshuam ntawm lub qhov (nplua nuj} hom semiconductor (nplua nuj nyob rau hauv cov tshuab hluav taws xob (nplua nuj nyob rau hauv cov tshuab hluav taws xob (nplua nuj nyob rau hauv cov tshuab hluav taws xob (nplua nuj nyob rau hauv cov tshuab hluav taws xob (nplua nuj nyob rau hauv cov tshuab hluav taws xob (nplua nuj nyob rau hauv cov tshuab hluav taws xob (nplua nuj nyob rau hauv cov tshuab hluav taws xob (nplua nuj nyob rau hauv electrons). Thaum lub diode biased (nrog P Teginal txuas nrog rau lub chaw zoo electrode thiab cov neeg nqa khoom txaus ywj siab, kev ua kom muaj kev tawm tsam dawb; Thaum thim rov qab, cov chaw tsis tau txais cov dav dav dav, tso cai tsuas yog qhov tam sim no kom dhau los ntawm, nthuav qhia lub xeev siab tiv taus. Cov xeeb ceem no ua rau diodes lub ntuj "Electronic valve" uas tuaj yeem tswj hwm cov kev taw qhia tam sim no.

Cov tsis tseem ceeb:

Forwar rau pem hauv ntej Voltage poob (VF): Hais txog 0.6-0.7v rau Silicon diodes thiab qis li 0.15-0.4V rau schottky diodes.
Rov qab lub sijhawm rov qab (TRR): dog dig
Hloov qab tawg voltage (VRRM): nws txiav txim siab qhov kev thim rov qab ntau tshaj plaws uas tus diode tuaj yeem tiv thaiv tau thiab yog qhov ntsuas tau pov thawj rau kev xaiv cov ntawv thov hluav taws xob.
2, Raug Daim Ntawv Teev Npe Ntawm Lub Hwj Chim Daim Phiaj Xwm Txheej Txheem Kev Tswj Xyuas
1. Rectification thiab DC Fais Fab System
Nyob rau hauv ncaj qha tam sim no kis tau qhov txuas ntawm lub hwj huam txuas ntawm daim phiaj hluav taws xob (xws li peb {{}}} voltage ncaj qha tam sim no kis tau tus (HVDC). Piv txwv li, nyob rau hauv ± 800kv ultra-}}} Cov Khoom Noj Ntawm Cov Khoom Kub Tam Sim No

Txhim Kho Rau Lub Tswv Yim:

Siv cov nrawm dua diodes (FRD) lossis silicon carbide (sic) diodes kom txo rov qab poob rov qab los.
Los ntawm kev siv cov kev sib txuas ua ke tam sim no sib faib thev naus laus zis los rhuav cov cuab yeej tam sim no thiab txhim kho cov cuab yeej kev ntseeg tau.
2. Kev ntsuas kev cais tawm hauv kev sib xyaw ua ke ntawm lub zog tshiab rau hauv kab sib chaws
Hauv photovoltaic inverters thiab cua fais fab hloov dua siab tshiab, diodes tau siv los tiv thaiv lub zog hluav taws xob rov qab rau daim phiaj. Piv txwv li, photovoltaic arrays tau txuas nrog inverters los ntawm dodes. Thaum lub zog sib zog tsis ua haujlwm lossis cov inverter kaw cia, txoj kev ua kom rov qab los thaiv qhov kev thim rov qab, tiv thaiv cov khoom siv los ntawm kev puas tsuaj.

Ntaub Ntawv Tshawb Xyuas:
Qhov chaw nres tsheb 10mw photoovoltaic lub zog uas yog ib hom kev sib txuas ua ke, nrog txhua tus photovoltaic kuj txuas nrog cov koob nrog dodes. Cov ntaub ntawv ntsuas tiag tiag qhia tau tias thaum cov Grid Voltage poob mus rau 30%, cov diode muaj peev xwm thaiv tam sim no, kom nrawm nrawm nrawm nrawm nrawm.

3. Kev tiv thaiv kev tiv thaiv thiab kev sib cais
Nyob rau hauv cov khoom siv hluav taws xob relay tiv thaiv ntawm lub hwj chim sib xyaw, diodes ua ke nrog cov khoom siv uas zoo li cov thyristors thiab i -- tawm ntawm kev txhaum qe. Piv txwv li, DC cov laj kab hluav taws xob siv cov backing blocking cov yam ntxwv ntawm diodes los cais lub ceg txhaum nyob rau hauv qhov kev txhaum, tiv thaiv kev kis ntawm qhov txhaum.

Technologity Tog:
Lub DC Circuit Court breaker raws li Sifet Hybrid tuaj yeem txiav tawm ntau txhiab tus neeg tsis txaus siab ntau tshaj 10 zaug sai dua li kev sib txuas ua ke sib txuas.

4. Cov teeb meem kev sib txuas lus thiab kev sib txuas lus
Nyob rau hauv Fais Fab LINE cov cab kuj kev sib txuas lus (plc), dodes tau siv rau teeb liab kev hloov kho thiab demodulation. Piv txwv li, los ntawm kev siv DIode pom kev mus rau extract siab {1} {} Lub sij hawm kis tau cov ntaub ntawv fais fab tuaj yeem ua tiav.

Daim Ntawv Thov Piv Txwv:
Hauv kev tsim kho ntawm lub xeev daim phiaj "Ubiquitous zog Internet ntawm tej yam", PLC ua tiav cov ntaub ntawv faib tawm ntawm 10Mblet faib cov kab nrog tsawg dua 10 ^ -6.

3, Cov hom phiaj kev sib tw thiab kev ua kom ua tau zoo nyob rau hauv daim ntawv thov fais fab
1. Kev ntseeg tau teeb meem hauv siab - voltage thiab siab tratararios
Nyob rau hauv Ultra - huab voltage loj yuav tsum tau tiv thaiv ntau txhiab thiab lawv cov yam ntxwv rov qab los ntawm voltage, ua rau cov khoom siv hluav taws xob, ua rau ntaus ntawv tsis ua haujlwm.

Kev daws:

Cov Ntaus Ntaus Xaiv: Sic Diodes tau nyiam raws li lawv muaj 90% tus nqi luv luv rov qab lub sijhawm thiab kev txo qis hauv kev ua kom tiav rau silicon diodes.
Kev tsim kev nqus cov qauv: parallel rc tsis sib txuas yog txuas rau ntawm ob xaus ntawm diode voltage voltage spikes. Piv txwv li, nyob rau hauv ± 1100KV DC Project tau raug txo los ntawm 2.1 npaug ntawm tus nqi ntsuas rau 1.3 zaug los ntawm kev ua kom zoo RC tsis sib xws.
2. Electromagnetic cuam tshuam (EMI) Kev Txom Nyem
Lub siab - zaus aycillation getated thaum lub sij hawm rov qab rov qab los yog emi thiab cuam tshuam nrog hluav taws xob sib txuas lus sib txuas lus.

Kev ntsuas dav:

Teeb tsa optimization: luv luv qhov ntev ntawm diode ua thiab txo qis kev tsis sib xws.
Lim Tsim: Ntxiv hom kev inductance thiab y capital accters rau cov zis davhlau ya nyob twg ntawm cov diode to suppress high {{0} suab nrov. Kev soj ntsuam tiag tiag qhia tau hais tias qhov opi radiation kev sib zog yog txo los ntawm 15DB.
3. Qhov ntsuas kub thiab lub neej lifaban
Cov khoom siv ua haujlwm ntawm cov khoom siv fais fab hluav taws xob yog cov nyom, thiab qhov kub siab yuav ua rau muaj kev kub ntxhov thiab kub thiab txias thiab kev laus ntawm cov txheej txheem.

Kev Txheej Txheem Qhia:

Thermal tsim: Siv lub dab dej sov thiab kua txias tshuab los tswj qhov kub npau taws hauv qab no 150 qib.
Kev twv ua neej lub neej: raws li txoj kev sib tshuam kub thiab cov qauv kev ntxhov siab tam sim no, tsim kom muaj Diode lub neej ua ntej kev twv ua ntej cov kev ua ntej muaj kev tiv thaiv kev tiv thaiv.
