Sisitemu z'amashanyarazi zikoresha amashanyarazi (EV) zifite ubwoko bwinshi bwa capacitors.
Kuva kuri capacitors za DC-link kugeza kuri capacitors z’umutekano na capacitors zidafite ubushobozi bwo gupima, ibi bice bigira uruhare runini mu gutuza no kurinda ibikoresho by’ikoranabuhanga nk’ingufu z’amashanyarazi n’ihungabana ry’amashanyarazi (EMI).
Hari imiterere ine y'ingenzi ya inverters zikoresha imbaraga, zitandukanye bitewe n'ubwoko bwa switch, voltage n'urwego. Guhitamo topology ikwiye n'ibice bifitanye isano ni ingenzi mu gushushanya inverters zikoresha imbaraga zijyanye n'ubushobozi n'igiciro bya porogaramu yawe.
Nkuko byavuzwe, hari topolojia enye zikoreshwa cyane muri inverters za EV traction, nk'uko bigaragara ku Ishusho ya 2.
-
Topology yo mu rwego ifite switch ya 650V IGBT
-
Topology yo mu rwego ifite switch ya 650V SiC MOSFET
-
Topology yo mu rwego ifite switch ya 1200V SiC MOSFET
-
Topology yo mu rwego ifite 650V GaN Switch
Izi topolojia zigabanyijemo ibice bibiri: Powertrains za 400V na Powertrains za 800V. Hagati y’ibi bice bibiri, ni ibisanzwe gukoresha topolojia "z’urwego rwa 2". ...

Ibikoresho byo gukata ibintu bito– Kugabanya ingufu z'amashanyarazi ni ingenzi mu kurinda imiyoboro minini y'amashanyarazi. Capacitors zihuza n'agace gakoresha ingufu z'amashanyarazi menshi kugira ngo zirinde ingufu z'amashanyarazi.

Ibikoresho bya DC-Link Capacitors– Mu bikorwa bya EV, Capacitors za DC-link zifasha mu kugabanya ingaruka zo guhindagurika kw'amashanyarazi mu byuma bihindura amashanyarazi. Zikora kandi nk'ibiyungurura bikingira sisitemu nto za EV ku kwiyongera kwa voltage, surges na EMI.
Izi nshingano zose ni ingenzi cyane ku mutekano n'imikorere ya inverters zikoresha imbaraga, ariko imiterere n'ibipimo by'izi capacitors birahinduka bitewe n'imiterere ya inverters zikoresha imbaraga uhisemo.
