Tshiab zog tiam: txhim kho photovoltaic inverter efficiency
Hauv cov tshuab hluav taws xob photovoltaic, SiC diodes siv rau DC -AC inverters tuaj yeem txo qhov kev hloov pauv los ntawm 30% thiab txhim kho kev ua haujlwm ntawm 2-3 feem pua. Noj 100MW photovoltaic fais fab chaw nres tsheb ua piv txwv, lub zog txhua xyoo tuaj yeem nce 2 lab kWh thiab txo cov pa roj carbon dioxide emissions los ntawm 1600 tons.
Hluav taws xob tsheb: Shortening lub sij hawm them nqi thiab Extending Range
Nyob rau hauv 800V siab-voltage fast charging platform, SiC diodes thiab MOSFETs ua hauj lwm ua ke los ua kom lub zog ceev ntawm lub charging module mus rau 35kW / L, thiab kev them nqi nce mus txog 98%. Tom qab siv SiC cov khoom siv fais fab, Tesla Model 3 tau nce nws qhov ntau los ntawm 5% thiab txo lub sijhawm them los ntawm 20%.
Industrial motors: txo kev siv hluav taws xob thiab cov nqi tu
Cov tshuab hluav taws xob muaj peev xwm suav txog 45% ntawm kev siv hluav taws xob thoob ntiaj teb, thiab kev hloov pauv zaus siv SiC diodes tuaj yeem ua kom lub cev muaj zog ntawm 85% mus rau 95%. Piv txwv li, tom qab kev kho dua tshiab ntawm ib lub tuam txhab steel, kev txuag hluav taws xob txhua xyoo mus txog 120 lab kWh thiab carbon emissions raug txo los ntawm 96000 tons.
Data Center: Optimizing Power Management thiab Txias
Kev siv hluav taws xob ntawm cov chaw zov me nyuam suav txog 2% ntawm lub ntiaj teb tag nrho, thiab kev siv SiC diode fais fab modules tuaj yeem txo PUE (Power Usage Efficiency) tus nqi qis dua 1.1. Noj cov ntaub ntawv loj loj hauv cov chaw ua piv txwv, txhua xyoo kev txuag hluav taws xob ntau tshaj 50 lab kWh, uas yog sib npaug los txo qhov kev siv ntawm 40000 tons ntawm cov qauv thee.

Tawm tsam keeb kwm yav dhau los ntawm kev hloov kho thoob ntiaj teb cov saw hlau, Tuam Tshoj txoj kev lag luam diode tau txav los ntawm "ua raws li qhov sib txawv" mus rau "ua txoj hauv kev" los ntawm kev siv thev naus laus zis thiab kev sib koom ua ke ntawm ecological.

Cov khoom kawg: Kev nthuav dav ntawm SiC substrate muaj peev xwm ntau lawm
Cov chaw lag luam hauv tsev xws li Tianyue Advanced thiab Sanan Optoelectronics tau ua tiav cov khoom loj ntawm 6-nti SiC substrates, nrog lub ntiaj teb tsim muaj peev xwm ntawm 30% los ntawm 2025. Tus nqi substrate tau txo qis los ntawm 60% piv rau 2020, tsav tus nqi ntawm SiC diodes los ntawm $ 10 ib nti rau cov khoom siv hluav taws xob rau $ 2, ib qho khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
Manufacturing kawg: iterative ntim thiab kuaj tshuab
Cov tuam txhab lag luam hauv tsev siv cov khoom ntim khoom siv me me xws li DFN thiab SODFL kom txo cov kab mob parasitic inductance los ntawm 50% thiab hloov mus rau siab - ntom PCB layouts. Piv txwv li, Shilanwei's 1200V SiC diode tau ntim rau ntawm tooj liab substrate, uas txo qhov kub nce los ntawm 40℃piv rau cov khoom ib txwm siv thiab txhim kho kev ntseeg tau zoo.
Daim ntawv thov kawg: Sib sib zog nqus khi ntawm ecological saw
BYD, Huawei Digital Zog thiab lwm qhov chaw tsim khoom lag luam koom tes nrog cov tuam txhab diode los tsim cov khoom lag luam. Piv txwv li, Yangjie Technology tau koom tes nrog BYD los tsim tsheb qib SiC diodes, uas tau siv dav hauv Han EV qauv nrog ib lub tsheb tus nqi ntau dua 500 yuan, tsim lub kaw - voj ecosystem ntawm "cov ntaub ntawv chips systems".
