Lub cev muaj zog tswj kev lag luam
4.1 Kev ruaj ntseg siab
Torque kev ruaj ntseg los ntawm: SBC + MCU saib xyuas kev lag luam, kev siv hluav taws xob ntsig txog kev ruaj ntseg, kev tsav tsheb muaj feem xyuam tsav, kev txhim kho ntawm IGBT kev txhaum, kev ywjpheej txoj kev kaw kev ruaj ntseg, resolver teeb liab kev ywj pheej ntawm ADC channel, high-quality two- channel high- voltage sampling Circuit Court, ntau qhov zoo Peb theem tam sim no muaj qhov sensor.
4.2, siab EMC ntsuam xyuas
Tam sim no tus thib ob tiam ntawm cov khoom yuav muaj peev xwm ua class3, class4, thiab tom qab EMC yuav ua class5, yuav tsum tau ntsuas los ua miniaturized thiab txo nqi. EMC tus cwj pwm ntxawg tshiab yog qhov chaw: nrog rau cov ntsiab lus zoo dua, cov nqi qis dua EMC ntaus nqi raws li cov qib siab EMC. Yog tias EMC tseev kom muaj hoob 5, qhov sib npaug ntawm qhov tsawg tshaj 5% thiab tus nqi tsawg tshaj 50RMB.
Kev tshawb nrhiav cov ntsiab lus muaj xws li: "Electronic control + motor" system EMC tov, cov cuab yeej cuab tam EMC cov kev tshawb nrhiav thiab kev daws, "Electronic control + motor" system EMC simulation platform.
4.3, siab siab
Qhov tseem ceeb rau cov neeg tsav tsheb, tam sim no qhov hluav taws xob feem ntau yog nyob ib ncig ntawm 300-400V, thiab muaj peev xwm tsim tawm mus rau qhov siab zog yav tom ntej. Super ceev them nyiaj thiab lub zog xav tau nce yog sab hauv kev tsav tsheb rau kev siab zog ntawm hluav taws xob tsheb. Yog hais tias qhov hluav taws xob uas tau them ntxiv ntawm 400V mus rau 800V, lub sij hawm them rov qab yuav luv zog los ntawm ib nrab. Daim ntawv no yuav tsum raug kho dua tshiab, cov tsheb fais fab yuav nrov nrov rau yav tom ntej, thiab qhov muaj zog siab yog ib txoj kev loj hlob. Raws li kev sib tham no, tus tsim cov inverters yuav tsiv tawm ntawm 650V IGBT tsim rau siab dua 750V thiab 1200V IGBT.
4.4, siab zog loj
Los ntawm cov seem ntawm lub ntim, qhov sib txawv ntawm cov khoom siv yooj yim-rau-siv rau cov square cib, ultra-nyias rho los, thiab thaum kawg liab qab DBC / nti cov ntawv tau hloov zuj zus. Lub ntim ntawm lub pob yuav tsum muaj me me nrog lub chaw sib koom ua ke. Nyob rau hauv 2018 los yog yav tom ntej, nws muaj peev xwm ncav cuag 1/10 ntawm qhov loj ntawm lub xyoo 2013.
Los ntawm cov nti dimension mus rau high efficiency thiab kev khiav hauj lwm qib siab kub, xws li E3 nti, kev sib txuas qhov kub thiab txias yog 150 ° C, lub EDT2 nti kev sib tov kub tau nce mus txog 175 ° C, SIC silicon carbide chip yuam kev tuaj yeem tshaj 175 ° C, yog tias E2 Lub hwj chim poob hwjchim yog 1, thiab tom kawg ob lub hwj huam poob ntawm 0.8 thiab 0.3 mus rau 0.5, feem. Kev siv SiC cov cuab yeej ua tau txo cov kev hloov pauv, ua kom zoo zog, txo cov sij hawm tuag, thiab ua kom muaj qhov tso zis. Los ntawm tag nrho kev saib xyuas ntawm lub roj teeb pob thiab xws li, tag nrho tus nqi txo 5%, thiab kev nce qib nce 10% ntawm qhov kev xav ntawm tag nrho cov tsheb. Tag nrho kev ua tau zoo tuaj yeem tsim kho tau los ntawm kev siv SiC.
Nrog txoj kev loj hlob ntawm cov khoom siv thiab kev tsim cov ntim cov tshuab, cov nqi twv yuav raug txo kom tsawg.
Nyob rau hauv cov nqe lus ntawm cov khoom qhov ntev, tus maub los rau supplying hippocampus yuav ncav 18kW / L, thiab lub hwj chim ceev ntawm lub thib ob lub tsheb nrog tus neeg tsav tsheb yuav tsum 26kW / L. Qhov tseeb tus neeg tsav tsheb lub tsheb yuav ua tau 35kW / L. Yav tom ntej, SiC cov ntaub ntawv yuav tsum ua kom ncav muaj zog ntawm 45 kW / L.
4.5, ntaus kev sib txuas thiab kev kho
Muaj kev nyab xeeb, muaj kev sib koom tes:
Muaj kev nyab xeeb, muaj ntau zaus:
Tsav rho tawm IC: kev ruaj ntseg, kev sib xyaws siab:
Cov qauv capacitors muaj tau customized, txawm integrating EMC rau cov qauv capacitors. Piv txwv li, tus maub los ntawm EMC Y capacitor, tus thawj tswj hwm, yuav muab tso rau yav tom ntej. Qhov no yog lub cev muaj zog lub cev, thiab lub neej yav tom ntej kuj tseem mus rau kev sib tos.
