Nyob rau hauv xyoo tas los no, kev loj hlob ntawm kev lag luam hluav taws xob tshiab xws li photovoltaic cia thiab hluav taws xob tsheb (EVs) tau ua rau muaj kev xav tau ntau ntxiv rau DC-Link capacitors. Hauv luv luv, DC-Link capacitors ua lub luag haujlwm tseem ceeb hauv Circuit Court. Lawv tuaj yeem nqus cov mem tes siab tam sim no ntawm lub tsheb npav kawg thiab ua kom lub tsheb npav tsis muaj zog, kom ntseeg tau tias IGBT thiab SiC MOSFET keyboards raug tiv thaiv los ntawm qhov tsis zoo ntawm cov mem tes tam sim no thiab cov hluav taws xob hloov pauv thaum lub sijhawm ua haujlwm.
Raws li lub tsheb npav voltage ntawm lub zog tshiab tsheb nce los ntawm 400V rau 800V, qhov kev thov rau zaj duab xis capacitors tau nce ntau. Raws li cov ntaub ntawv, lub peev xwm ntsia tau ntawm cov hluav taws xob tsav inverter raws li DC-Link nyias-zaj duab xis capacitors mus txog 5.1117 lab teev hauv 2022, suav txog 88.7% ntawm lub peev xwm ntawm kev tswj hluav taws xob. Cov tsav inverters ntawm ntau lub tuam txhab tswj hluav taws xob xws li Tesla thiab Nidec txhua tus siv DC-Link zaj duab xis capacitors, uas suav txog 82.9% ntawm lub peev xwm nruab thiab tau dhau los ua qhov kev xaiv tseem ceeb hauv kev lag luam hluav taws xob.
Cov ntaub ntawv tshawb fawb qhia tau hais tias nyob rau hauv silicon IGBT ib nrab-bridge inverters, cov tsoos electrolytic capacitors feem ntau yog siv nyob rau hauv DC txuas, tab sis voltage surges yuav tshwm sim vim ESR siab ntawm electrolytic capacitors. Piv nrog silicon-based IGBT cov kev daws teeb meem, SiC MOSFETs muaj qhov hloov pauv ntau dua, yog li qhov hluav taws xob surge amplitude hauv DC txuas ntawm ib nrab choj inverter yog siab dua, uas yuav ua rau cov cuab yeej ua haujlwm tsis zoo lossis txawm tias puas tsuaj, thiab cov zaus resonant ntawm electrolytic capacitors tsuas yog 4kHz txaus rau cov khoom siv tam sim no.
Yog li ntawd, nyob rau hauv DC daim ntawv thov xws li hluav taws xob tsav inverters thiab photovoltaic inverters nrog kev ntseeg siab dua,zaj duab xis capacitorsfeem ntau yog xaiv. Piv nrog txhuas electrolytic capacitors, lawv cov kev ua tau zoo yog qhov muaj zog dua, qis ESR, tsis muaj polarity, kev ua haujlwm ruaj khov, thiab lub neej ntev dua, yog li ua kom muaj zog ripple tsis kam thiab txhim khu kev qha system tsim.
Cov tshuab siv nyias zaj duab xis capacitors tuaj yeem ua kom zoo dua ntawm qhov siab zaus thiab qis qis ntawm SiC MOSFETs thiab txo qhov loj thiab qhov hnyav ntawm cov khoom siv passive. Wolfspeed kev tshawb fawb qhia tau hais tias ib tug 10kW silicon-raws li IGBT inverter yuav tsum tau 22 txhuas electrolytic capacitors, thaum ib tug 40kW SiC inverter tsuas yuav tsum tau 8 nyias-film capacitors, thiab PCB cheeb tsam kuj zoo heev txo.
Nyob rau hauv teb rau kev lag luam xav tau, YMIN Electronics launched lubMDP series ntawm zaj duab xis capacitors, uas siv cov thev naus laus zis siab thiab cov ntaub ntawv zoo los hloov mus rau SiC MOSFET thiab silicon-based IGBT. MDP series capacitors feature qis ESR, siab tiv taus hluav taws xob, tsis tshua muaj hluav taws xob tam sim no thiab kub kub stability.
Qhov zoo ntawm YMIN Electronics 'film capacitor khoom:
YMIN Electronics 'film capacitor tsim siv lub tswv yim qis ESR los txo qhov kev ntxhov siab thiab lub zog poob thaum hloov thiab txhim kho lub zog ua haujlwm. Nws muaj qhov ntsuas hluav taws xob siab, hloov mus rau qhov chaw muaj hluav taws xob siab, thiab ua kom lub cev muaj zog.
MDP series capacitors muaj peev xwm ntawm 1uF-500uF thiab qhov hluav taws xob ntau ntawm 500V txog 1500V. Lawv muaj qis dua tam sim no thiab siab dua kub stability. Los ntawm cov ntaub ntawv zoo thiab cov txheej txheem siab heev, cov qauv hluav taws xob muaj txiaj ntsig zoo yog tsim los ua kom muaj kev ruaj khov ntawm qhov kub thiab txias, ua kom ntev kev pab cuam lub neej, thiab muab kev txhawb nqa zoo rau lub zog hluav taws xob. Nyob rau tib lub sijhawm, lubMDP series capacitoryog compact loj, siab zog ceev, thiab siv cov txheej txheem nyias-zaj duab xis tsim los txhim kho kev sib koom ua ke thiab kev ua haujlwm zoo, txo qhov loj thiab qhov hnyav, thiab ua kom cov khoom txav tau yooj yim thiab yooj yim.
YMIN Electronics DC-Link zaj duab xis capacitor series muaj 30% kev txhim kho hauv dv / dt kam rau ua thiab 30% nce hauv kev pab cuam lub neej, uas txhim kho kev ntseeg siab ntawm SiC / IGBT circuits, coj tus nqi zoo dua, thiab daws qhov teeb meem ntawm tus nqi.
