Yuav ua li cas tuaj yeem ua kom zoo dua lub zog hloov pauv kev ua tau zoo hloov pauv hluav taws xob?

1, kev sib tw ntawm lub zog hloov pauv tau zoo thiab lub luag haujlwm ntawm dodes
Hauv tshav pob hluav taws xob ntawm cov neeg siv khoom lag luam, hluav taws xob hloov siab hloov zuj zus ntawm kev ntsuas cov ntsuas tseem ceeb rau kev ntsuas ntaus ntawv. Nrog rau kev nce zuj zus ntawm cov khoom siv hluav taws xob, los ntawm smartphones rau kev tswj hwm kev ua si: me dua qhov loj me, thiab roj teeb ntev dua lub neej. Txawm li cas los xij, muaj ntau cov peev txheej hloov kho hluav taws xob hloov kho lub zog, ntawm cov yam ntxwv ntawm dodees muaj kev txiav txim siab txiav txim siab ntawm kev ua kom tag nrho.
Dailes tsuas yog ua rectification, freewheeling, thiab clamping lub zog nyob rau hauv lub fais fab hloov dua siab tshiab. Kev noj lub xov tooj smeebe raws li ib qho piv txwv, AC lub zog yuav tsum hloov dua siab tshiab rau 10% - 15% ntawm tag nrho cov hluav taws xob tau noj. Ib qho ntxiv, hauv DC-DC cov hloov dua siab tshiab, TRR) ntawm Diode tuaj yeem ua rau voltage spikes, ntxiv zuj zus poob.
2, txoj kab thev naus laus zis rau kev ua kom tau zoo kawg Diode efficiency
Hauv kev teb rau cov ntsiab lus mob saum toj no, engineers yog txhawb kev hloov zuj zus ntawm kev ua haujlwm siab los ntawm cov khoom txhim kho, kev txhim kho cov txheej txheem, thiab kev tsim qauv cathruit
Qis rau pem hauv ntej siab nco thev naus laus zis
SCHOTTKY DIBODE: Siv Hlau Semiconductor Sib cuag es tsis txhob siv cov kev sib tw PN kom txo qis vf rau 0.2-0.4V. Tom qab siv schottky diodes nyob rau hauv ib lub sij hawm them nyiaj ceev, Rectification poob tau raug txo los ntawm 60% thiab ua haujlwm nce ntxiv ntawm 82% rau 88%.
Rectifier Super Fectifier (SBR): sib txuas ntawm kev tsim txom Mos Technology nrog kev tswj hwm qis dua VF, cov xau dej qis (ir) yog muab piv rau kev kawm ib txwm muaj. Thaum 85 degree, lub to tam sim no ntawm sbr yog tsuas yog 1.7 μ μ A, thaum tib hom schottky nce 18 μ a.
Kev Nraj Rov Qab Rov Qab Los Tshuab
Fast rov qab ua hauj lwm Diode (FRD): los ntawm kev ua kom zoo doping thiab cov qauv tsim qauv, TRR yog luv rau hauv 30ns. Nyob rau hauv high - zaus hloov hluav taws xob (xws li lub zog hloov hluav taws xob), FD txo qis dua poob los ntawm 75%.
Silicon Carbide (Sic) Diodide (Sic) Diode: Siv Bandgap Triconductor ntau zaus, thiab rov qab them rov qab them (QRR) ze rau xoom. Kev ua tau zoo ntawm ib qho txheej txheem sic diode yog 3% siab dua li ntawm lub silicon-}}}}}}}}}}}}}}} Raws li cov zaus ntawm 400kHz.
Kev Tswj Cov Kev Tswj Hluav Taws Xob thiab Ntim Innove
Cua sov dissipation optimization: rau-220 ntim sib xyaw nrog tooj liab substrate txo cov thermal tiv thaiv los ntawm 40%. Thaum lub zog hluav taws xob module ntawm qee yam kev twv txiaj yog tag nrho cov kev sib tshuam nrog kub, ntsuas kub dauv los ntawm 125℃rau 85 degree, txhim kho kev ruaj khov.
Kev tsim qauv: ua ke rau cov kev lom zem thiab cov mosfets rau hauv lub zog hluav taws xob txo qis parasitic inducations los ntawm 50%, txo lub suab nrov, thiab muaj peev xwm nce ntxiv los ntawm 1.5%.
3, cov ntaub ntawv thov raug rau hauv Cov Khoom Siv Khoom Siv Hluav Taws Xob
Xov tooj Ntse Xov Xwm ceev thev naus laus zis
Cov ntaub ntawv: ib tug 65w Gallium Nitride Charger tau txais kev daws teeb meem ntawm SBR Diode thiab Gan transistor.
Cov nyhuv:
Kev ua tau zoo tau nce los ntawm 85% rau 92.5% hauv cov tshuaj silicon;
Qhov ntsuas kub nce ntxiv los ntawm 5℃thiab lub ntim shrinks los ntawm 30%;
Txhawb PD3.1 raws tu qauv, ua tiav 60% them rau hauv 15 feeb.
Laptop Power Adapter
Cov ntaub ntawv: Loj zaus DC - DC Converter siv SIC DIODES (kev ua haujlwm ntau 500khz).
Cov nyhuv:
Kev ua tau zoo txog 95%, uas yog 4% siab dua cov kev daws teeb meem ib txwm muaj;
Qhov loj ntawm cov sib nqus tivthaiv tau raug txo los ntawm 40%, thiab cov tuab ntawm cov adapter tau raug txo mus rau 12mm;
Qhov tsis muaj {{{0} Siv zog siv hluav taws xob tsawg dua 50mW, uas ua tau raws li lub hnub qub lub hnub qub txheem.
Game Console Fais Fab Zog
Cov ntaub ntawv: Ps5 hluav taws xob tau txais ntau -}}}}}}}}}}}}}}
Cov nyhuv:
CPU / GPU fais fab khoom siv tau zoo txog 94%;
Cov kev teb hloov pauv tau nce los ntawm peb zaug thiab txhawb nqa lub zog hluav taws xob hloov;
Qhov ntim tag nrho ntim tau txo los ntawm 25%.
