3. Lub tsheb hluav taws xob them nyiaj: Kev ua tau zoo ua ke ntawm cov thev naus laus zis thev naus laus zis
Lub tsheb hluav taws xob them cov chaw nres tsheb yuav tsum tau hloov dua lwm txoj kev tam sim no mus rau hauv qhov tam sim no. Kev ua piv txwv ntawm cov tsoos tso cai tso cai yog txog 85%, thaum synchronus rectification thev naus laus zis tuaj yeem txhim kho kev ua tau zoo rau 98% los ntawm kev hloov cov diodes nrog mosfets. Txawm li cas los xij, nyob rau hauv high- kev siv cov ntawv thov, {kawg- kawg tiv thaiv, tiv thaiv kom rov qab cov lus qhia tam sim no.

Cov ntaub ntawv: ib yam 800v high - voltage them pob platform adopts HfaTky Diode (8A / 600V, Trr {} ns ns ns}. Nyob rau hauv dc {- DC Buck Module, ua ke nrog synchronous rechnology, kev them nyiaj tau zoo los ntawm 92% rau 95%, thiab lub sijhawm them nyiaj yog luv los ntawm 10 feeb.

2, Circuit Tsim Qauv: Qhov txheej txheem qib kev txhim kho kom txo qis
1. Topology Innovation: Choj Rectification thiab Muag Hloov Tshuab
Kev ua haujlwm ntawm ib txwm muaj RECETICATION yog tsuas yog 45%, thaum ntawm qhov kev kho mob puv me yog nce rau 81%. Kev ntsuas ntshav ua tiav tau tag nrho yoj kev siv los ntawm plaub tus qauv raj, nrog kev ua tau zoo ntawm ntau dua 90%. Kev sib xyaw ua ke ntawm cov tshuab muag hloov (xws li xoom Voltage hloov Zvs) tuaj yeem tshem tawm diode rov qab poob rov qab.

Cov ntaub ntawv: Ib qho chaw hluav taws xob cia khoom siv cov muag hloov mus rau qhov chaw, sib xyaw nrog SIC SC SCHOTTKY DONDES. Ntawm qhov zaus ntawm 100kHz, lub rectification efficiency yog nce ntawm 92% rau 96%, thiab lub kaw lus ntim yog txo los ntawm 30%.

2. Cua sov dissipation tsim: thermal tiv thaiv tswj thiab ntim kev ua kom zoo
Thaum lub sijhawm ua haujlwm siab tam sim no, cov cua sov ntawm ddayes yog lub ntsiab ua rau muaj kev ua tau zoo. Tsawg thermal kuj ntim (xws li-247, dpak) ua ke nrog kua cua txias tuaj yeem tswj hwm qhov kub tshaj plaws hauv qab no 150 qib thiab txuas ntxiv lub neej ntaus ntawv.

Cov ntaub ntawv: Ib co photovoltaic inverter siv dhuav dhuav, ua hauj lwm nrog kua cua txias ntawm 40 degree, nrog ib lub neej muaj ntev tshaj li ib txwm muaj pa taws.

3. Emi supression: tsawg capacitance ntim thiab lim tshuab
Lub nrawm nrawm ntawm Schottky diodes yuav qhia siab siab {0} suab nrov, thiab EMI lub suab nrov, thiab EMI lub suab nrov, thiab EMI lub suab nrov yuav tsum tau dhau los ntawm QRR (rov qab them nyiaj rov qab) ntim thiab lc lim voj voog.

Cov ntaub ntawv: Ib lub tsheb hluav taws xob them tus nqi hloov kho Module kuj muaj peev xwm capacitance schottky diodes (CJ<50pF), combined with common mode inductors, to reduce conducted interference to below CISPR 25 standard, and has passed the vehicle regulatory level certification.
