Gutembera mu buryo bwa tekiniki | Ni gute DC-Link Film Capacitors ishobora gukemura ibibazo by’ubwiyongere bw’amashanyarazi n’ubwirinzi mu miyoboro ya 800V Electric Drive?

Intangiriro

Uko urubuga rwa 800V rufite voltage nyinshi rugenda rukoreshwa mu modoka nshya zikoresha ingufu, inverters zikoresha amashanyarazi zirimo gushyira ingufu nyinshi ku miterere ya DC-Link capacitors zikoresha amashanyarazi. Capacitors zikoresha amashanyarazi za aluminiyumu zisanzwe, zigamirwa n’ubwiyongere bwa ESR n’umuvuduko wazo, zikunze kugira voltage nyinshi, bikagabanya imikorere myiza ya sisitemu kandi bikabangamira imikorere yuzuye y’ibikoresho bya SiC.

Ibisubizo bya YMIN Filimi Capacitor

- Isesengura rya Tekiniki rya Root Cause – Bitewe n'imiterere yabyo n'imiterere yabyo, capacitors za aluminium electrolytic ubusanzwe zifite ESR iri hejuru n'umuvuduko muto wo kwihuza (ubusanzwe hafi 4kHz gusa). Mu gihe cyo guhinduranya umuvuduko mwinshi, ubushobozi bwazo bwo kwinjiza umuvuduko mwinshi wo kwihuza ntabwo buhagije, bigatuma byoroshye guhinduranya umuvuduko wa bisi, ibyo bigatuma habaho imikorere myiza ya sisitemu n'ubuzima bw'ibikoresho by'amashanyarazi. – Ibisubizo bya YMIN n'Ibyiza by'Imikorere –Urukurikirane rwa MDP rwa YMINCapacitors za filime zikoresha ibikoresho bya filime ya polypropylene by'icyuma hamwe n'uburyo bushya bwo kuzigama kugira ngo zigere ku kunoza imikorere bikurikira: ESR igabanuka ikagera ku rwego rwa miliohm, bigabanya cyane igihombo cyo guhindura; frequency ya resonant yongerwa ikagera kuri mirongo ya kHz, ihuza neza n'ibisabwa na SiC / MOSFET mu gukoresha frequency nyinshi; kandi ibyiza byazo birimo voltage ikomeye, umuyoboro muto wo gusohoka, no kuramba igihe kirekire, bigatuma zikoreshwa neza cyane mu nyubako zikora volteji nyinshi kandi zikoresha frequency nyinshi.

Imiterere y'Ikoreshwa n'Ibyitegererezo Bisabwa -

Ikoreshwa Risanzwe: Platforme y'amashanyarazi ya 800V y'uruganda rukora imodoka ikoresha capacitors umunani za MDP-800V-15μF muri DC-Link circuit ya inverter y'imodoka nini, igasimbuza neza capacitors 22 za aluminiyumu 450V electrolytic za aluminium original. Ibi bigabanya ubuso bwa PCB ku kigero kirenga 50%, bigabanya uburebure bwa voltage ya bisi ku kigero cya 40%, kandi binongera imikorere myiza ya sisitemu ku kigero cya 1.5%. - Moderi zisabwa -

Umwanzuro
Uruhererekane rwa YMIN MDP si capacitor ifite imikorere myiza gusa, ahubwo ni n'igikoresho cy'ingenzi cyo kugenzura amashanyarazi muri sisitemu zifite amashanyarazi menshi kandi zifite frequency nyinshi. Rushobora gufasha injeniyeri gukemura ibibazo by'imiterere no kunoza imikorere n'uburyo sisitemu ikora neza.
