Kev Tshawb Fawb Txog Kev Siv Tshuab | Cov Capacitors Zaj Duab Xis DC-Link Yuav Ua Li Cas Thiaj daws tau qhov teeb meem Voltage Surge thiab Kev Ntseeg Tau Hauv 800V Electric Drive Platforms?

Kev Taw Qhia

Thaum cov platforms hluav taws xob siab 800V tau dhau los ua lub hauv paus tseem ceeb hauv cov tsheb fais fab tshiab, cov inverters tsav hluav taws xob tau muab qhov kev thov siab dua rau cov yam ntxwv siab ntawm DC-Link capacitors. Cov capacitors hluav taws xob txhuas ib txwm muaj, txwv los ntawm lawv cov ESR siab thiab cov lus teb zaus, feem ntau yuav muaj hluav taws xob nce siab, txwv tsis pub lub kaw lus ua haujlwm zoo thiab cuam tshuam kev ua haujlwm tag nrho ntawm SiC cov khoom siv.

YMIN Cov Kev daws teeb meem Capacitor zaj duab xis

- Kev Tshawb Fawb Txog Kev Siv Tshuab Hauv Paus - Vim yog lawv cov khoom siv thiab cov yam ntxwv ntawm cov qauv, cov capacitors electrolytic aluminium feem ntau muaj ESR siab thiab qhov zaus qis qis (feem ntau tsuas yog nyob ib ncig ntawm 4kHz). Hauv qab kev ua haujlwm hloov pauv zaus siab, lawv lub peev xwm los nqus cov tam sim no zaus siab tsis txaus, yooj yim ua rau muaj kev hloov pauv voltage, uas cuam tshuam rau kev ruaj khov ntawm lub cev thiab lub neej ntawm lub zog. - YMIN Cov Kev daws teeb meem thiab Cov txiaj ntsig ntawm cov txheej txheem -YMIN cov koob MDPCov capacitors zaj duab xis siv cov khoom siv polypropylene metallized zaj duab xis thiab cov txheej txheem winding tshiab los ua tiav cov kev txhim kho kev ua tau zoo hauv qab no: ESR raug txo kom txog qib milliohm, txo qhov poob hloov pauv; qhov zaus resonant raug nce mus rau kaum tawm kHz, hloov kho tag nrho rau cov kev xav tau ntawm daim ntawv thov zaus siab ntawm SiC / MOSFETs; thiab lawv cov txiaj ntsig suav nrog qhov siab voltage, qis to tam sim no, thiab lub neej ntev, ua rau lawv tsim nyog rau qhov siab-voltage, siab-zaus ua haujlwm ib puag ncig.

Cov Xwm Txheej Thov thiab Cov Qauv Pom Zoo -

Cov Qauv Siv: Lub tuam txhab tsim tsheb loj lub platform tsav hluav taws xob 800V siv yim lub capacitors MDP-800V-15μF hauv DC-Link circuit ntawm lub inverter tsav tsheb loj, hloov pauv cov tshuaj qub 22 450V txhuas electrolytic capacitors. Qhov no txo ​​thaj chaw PCB ntau dua 50%, txo qhov siab tshaj plaws ntawm lub tsheb npav los ntawm 40%, thiab txhim kho qhov ua tau zoo ntawm lub system los ntawm kwv yees li 1.5%. - Cov Qauv Pom Zoo -

Xaus lus
Cov koob YMIN MDP tsis yog tsuas yog lub capacitor ua haujlwm siab xwb tab sis kuj yog lub zog tswj hluav taws xob tseem ceeb hauv cov kab ke high-voltage, high-frequency. Nws tuaj yeem pab cov engineers daws cov teeb meem tsim qauv thiab txhim kho kev ua haujlwm thiab kev ntseeg siab ntawm lub kaw lus.
