Nidaamyada korontada ku shaqeeya ee ku jira gawaarida korontada (EV) waxay leeyihiin noocyo kala duwan oo capacitors ah.
Laga soo bilaabo capacitors DC-link ilaa capacitors badbaadada iyo snubber capacitors, qaybahani waxay door muhiim ah ka ciyaaraan xasilinta iyo ilaalinta elektiroonigga arrimo ay ka mid yihiin korontada iyo faragelinta elektromagnetic (EMI).
Waxaa jira afar nooc oo topologies ah oo rogrogisyada jiidista ah, oo leh kala duwanaansho ku salaysan nooca beddelka, tamarta iyo heerarka.Doorashada topology-ga ku habboon iyo qaybaha la xidhiidha ayaa muhiim u ah samaynta rogo-rogayaasha oo buuxiya hufnaanta codsigaaga iyo shuruudaha kharashka.
Sida la sheegay, waxaa jira afar topologies aadka loo isticmaalo ee EV traction inverters, sida ku cad sawirka 2.:
-
Heerka Topology ee muujinaya 650V IGBT beddelka
-
Heerka Topology ee muujinaya 650V SiC MOSFET beddelka
-
Heerka Topology ee muujinaya 1200V SiC MOSFET
-
Heerka Topology ee muujinaya 650V GaN Switch
Topologiyadani waxay u kala baxaan laba qaybood: 400V Powertrains & 800V Powertrains.Inta u dhaxaysa labada qaybood, waxa aad u badan in la isticmaalo topologies "2-level".Topologies "heer badan" waxaa loo isticmaalaa hababka korantada sare sida tareenada korontada, taraamka iyo maraakiibta laakiin aad u caan ah sababtoo ah qiimaha sarreeya iyo kakanaanta.
-
Capacitors Snubber- Xakamaynta korantada ayaa muhiim ah si looga ilaaliyo wareegyada korontada waaweyn.Xirmooyinka Snubber waxay ku xidhmaan noodhka beddelka ee hadda-sare si ay uga ilaaliyaan korontadu korontadu.
-
DC-Link Capacitors- Codsiyada EV, Xidhiidhiyayaasha DC-ku waxay gacan ka geystaan dib u dhigista saamaynta inductance ee rogoyaasha.Waxay sidoo kale u adeegaan sida filtarrada ka ilaaliya nidaamka-hoosaadka EV ee kor u kaca korantada, kor u kaca iyo EMI.
Dhammaan doorarkan ayaa aad muhiim ugu ah badbaadada iyo shaqeynta rogoyaasha rogaha, laakiin naqshadeynta iyo qeexitaannada capacitors-ka ayaa isbeddelaya iyadoo lagu salaynayo topology-ga rogaha jiidista ee aad doorato.
