Masisitimu emagetsi emagetsi ari mumotokari yemagetsi (EV) ane ma capacitor akasiyana-siyana.
Kubva kuma capacitor eDC-link kusvika kuma safety capacitors nema snubber capacitors, zvikamu izvi zvine basa rakakosha mukudzikamisa nekuchengetedza magetsi kubva kuzvinhu zvakaita se voltage spikes uye electromagnetic interference (EMI).
Kune ma topology mana makuru ema traction inverters, ane musiyano zvichienderana nerudzi rwe switch, voltage uye levels. Kusarudza topology yakakodzera uye zvimwe zvinhu zvine chekuita nayo kwakakosha pakugadzira traction inverters dzinoenderana nekushanda zvakanaka kweapp yako uye zvinodiwa nemari.
Sezvambotaurwa, kune ma topologi mana anonyanya kushandiswa muma EV traction inverters, sezvakaratidzwa muMufananidzo 2.
-
Topology yeLevel ine switch ye650V IGBT
-
Topology yeLevel ine switch ye650V SiC MOSFET
-
Topology yeLevel ine switch ye1200V SiC MOSFET
-
Topology yeLevel ine 650V GaN Switch
Matopologi aya anowira muzvikamu zviviri: 400V Powertrains & 800V Powertrains. Pakati pezvikamu zviviri izvi, zvakajairika kushandisa matopologi e "2-level". Matopologi e "Multi-level" anoshandiswa mumasisitimu emagetsi akakwira akadai sezvitima zvemagetsi, matramway nezvikepe asi haanyanyi kufarirwa nekuda kwemutengo wakakwira uye kuomarara.

Zvishandiso zveSnubber- Kuderedza voltage kwakakosha kudzivirira macircuit kubva kuma voltage spikes makuru. Ma "snubber capacitors" anobatanidza kune "high-current switching node" kudzivirira magetsi kubva kuma voltage spikes.
-
DC-Link Capacitors- Mukushandiswa kwemagetsi, Macapacitor eDC-link anobatsira kuderedza mhedzisiro yeinductance muma inverters. Anoshandawo semafirita anodzivirira ma EV subsystems kubva ku voltage spikes, surges uye EMI.
Mabasa ese aya akakosha zvikuru pakuchengetedzeka uye kushanda kwema-traction inverters, asi dhizaini uye magadzirirwo ema-capacitor aya anochinja zvichienderana nekuti unosarudza rudzii rwe-traction inverter.
