Yuav ua li cas teeb tsa diodes nyob rau hauv cua zog cia Coupling Tshuab?

一, Diero hom xaiv: Txheeb xyuas raws li kev thov cov xwm txheej
Cov cua lub zog cia cov txheej txheem them rau ntau yam xws li cua ntau heev, thiab lub zog cia them thiab rho tawm. Muaj ntau qhov sib txawv hauv kev ua tau zoo ntawm diodes nyob rau hauv ntau hom kev coj txawv, thiab hom phiaj ntaus ntawv yuav tsum tau xaiv.

1. Rectification Txheej Txheem: Silicon Carbide Diodes txhim kho kev ua tau zoo hloov dua siab tshiab
Hauv AC / DC Rectifier Module ntawm Cua Turbines, Tsoos Kev tso cai- Cov pa rov qab los yog vim lawv cov ultra rov qab los them (TRR<10ns) and low forward voltage drop (Vf<0.3V). For example, Cree's GaN HEMT diode reduces reverse recovery loss by 90% compared to silicon-based devices at a switching frequency of 1MHz, resulting in rectifier module efficiency exceeding 98%. In the offshore wind power scenario, Siemens uses a diode flexible rectifier valve instead of a modular multi-level rectifier valve, and reduces the converter station's volume by 80%, weight by 65%, and transmission loss by 20% under the same transmission capacity through the bridge arm series integrated pulse control strategy.

2. Lub zog cia txuas: TVs Diode txhim kho kev tiv thaiv ntau
Hauv cov roj teeb lithium hluav taws xob cia cov tshuab, TVs diriodes clamp overvoltage mus rau ib qho chaw nyab xeeb nrog millisecond teb ceev ceev. Noj cov CT3.3 roj teeb module ntawm CATL ua piv txwv, thiab tau ntau tshaj 10 zaug lub sijhawm teb rau cov hluav taws tiv thaiv hluav taws. Rau roj cell zog cia cov tshuab, cataly combustioning sensors thiab tvs desard yuav tsum tau teeb tsa kom nrawm nrawm rau ntawm cov kab mob hydrogen nrawm. Qhib kev tawg ntawm cov khoom tawg ntawm cov khoom siv nyem yuav tsum tau tswj tsis pub dhau 0.01 MPa.

3. Photovoltaic uxiliary txuas: bypass diode optimized kev ua siab ntev
Hauv cov cua hnub ci zog cia cov nyiaj coupling, photovoltaic feem ntau muaj kev tso tawm sai sai ntawm cov zis ua rau lub zog. Los ntawm kev sib txuas ib qho bypass diode nyob rau hauv series nrog txhua txhua 18 -20 cov cheebtsam, cov tiv thaiv cov thaiv npog tau yooj yim tuaj yeem hloov pauv, txo lub zog. Piv txwv li, thaum ib lub xovtooj ntawm ib qho txuas, cov zis hluav taws xob ntawm kev teeb tsa ntawm kev hla dhau ntawm 75%, lub zog poob tuaj yeem tswj tsis pub dhau 10%. Tsis tas li ntawd, infrared kuaj xyuas cov tshuab yuav tsum tau siv los ntsuas cov khoom siv thiab kom sai chaw kub teeb meem thaum qhov sib txawv kub tshaj 10 degree.

2, topology optimization: Lub tsev muaj txiaj ntsig zoo thiab ntseeg tau lub zog hluav taws xob hauv hluav taws xob
Txoj kev txuas sab topology tody ncaj qha cuam tshuam lub zog hluav taws xob ntawm cov kab ke, thiab kev sib txig hloov txoj kev hloov pauv ntawm txoj kev sib txuas.

1. Anti Rov Qab Them Circuit Circuit Courcuit: Tsim kev tsim cov thaiv diode thiab mosfet
Cov tsoos P - Cov txheej txheem anti rov qab muaj teeb meem xws li siab ntawm kev tiv thaiv rov qab. Ti's LM74700 {5 5}} Q1 qib siab Diode Controllment tiav 0.01 ω ntawm qib rov qab los ntawm kev sib xyaw ua ke los ntawm kev sib xyaw ua ke thiab tswj Circuit Court. Hauv 48v tsawg-voltage system ntawm lub tsheb zoo tshaj plaws ntawm 15 Degree, thiab kev daws teeb meem tag nrho ntawm kev pheej hmoo ntawm kev ua haujlwm txias thaum pib txias.

2. Kev ntsuas ntau qib: Diode clamp Topology
Rau siab - voltage ncaj qha tam sim no kis tau los ntawm kev sib txuas multiVitors (NPIs nyob rau hauv series, txo tus voltage resultse yuav tsum tau hloov cov khoom siv. Nyob rau hauv lub ± 800kv ultra {}}} huab voltage ncaj qha rau cov neeg sib txawv ntawm tus kheej (th voltology txo qhov kev sib tw

3.
Nyob rau hauv lub hybrid lub zog cia cov txheej txheem muaj cov roj teeb lithium thiab cov neeg tsav tsheb loj, hluav taws xob muab tau los ua tiav los ntawm dodes. Lithium roj teeb them rau ntev-}} Power-}}}}} lub zog heads. Piv txwv li, hauv cov hluav taws xob cua fais sib txuas tswj lub tswv yim ntau dua li 5%, cov supercapacitor sai sai thiab tawm ntawm dody tus nqi rau hauv 2%; Thiab cov roj teeb lithium yog maj mam tswj hwm ntawm tus nqi ntawm 0.1C kom ntseeg tau tias SO (lub xeev them) yog tswj hwm nyob hauv thaj tsam muaj 20% -80%.

3, Kev tswj hwm cua sov tswj hwm: Tswj kub los ntawm cov qib sib tshooj rau qib theem
Lub thermal tsis ua hauj lwm yog ib qho tseem ceeb ua rau muaj zog cia lub zog, thiab kev ua kom zoo dua qub, thiab kev txhim kho qib thermal tsim.

1. Khoom siv hloov kho: dav bandgap semiconductor txo qhov kub
Sic diodes yuav tiv taus kub txog 600 degree, uas yog peb zaug siab dua silicon -} raws li cov khoom siv; Gan diodes tuaj yeem ua haujlwm stables ntawm 200℃thiab muab thermal redundancy rau 800V siab {{voltage platforms. Plaub tiam Sic los ntawm ROHM tau txais kauj ruam ob npaug, txo cov thermal tsis kam los ntawm 10k / w thiab ua kom muaj zog ntom nti ntawm ntau dua 100kw / l. Nyob rau hauv byd lub voos xwmfab hluavtsi cia cua txias cov khoom siv kub ua rau kub hauv qab no 45 degree, piv rau cov pa- txias tov.

2. Cov Txheej Txheem Kev Txhim Kho: 3D ntim thiab kos duab ua cua sov
Los ntawm stacking chips thiab kos duab cua sov dissipation qauv, lub thermal ua haujlwm ntawm dodes yuav raug txo qis. Piv txwv li, Infineon lub Smart Diode series sensors hauv lub nti kom ua tiav tiag {1} Kev saib xyuas VF tj nkhaus. Thaum qhov ntsuas kub nce mus txog qhov pib, ceeb toom yog muab 10 feeb ua ntej pib kev cuam tshuam rau kev tswj hwm kev tswj hwm.

3. Cov Txheej Txheem Qib Thermal Kev Coupling: Cua Sergret Cia Cov Syergy
Hauv cov cua lub hnub ci zog cia cov txheej txheem txiav, ib txoj kev sib koom ua ke thermal kev tswj hwm platform yuav tsum tau tsim. Piv txwv li, lub zog sib koom rau cov chaw nres tsheb fais, uas siv cov roj teeb hluav taws xob ntau yam los ua kom sov roj teeb los ntawm 30% mus rau 5% raws li cov mob hauv lub caij ntuj no. Nyob rau tib lub sijhawm, cov kua dej txias txias ntawm lub photovoltaic module Shares cua txias nrog cov roj hluav taws xob iav, ua tiav hluav taws xob Cascade.
