Iwo emagetsi masisitimu emagetsi mumotokari yemagetsi (EV) anoratidza akasiyana siyana ma capacitor.
Kubva kuDC-link capacitors kuenda kune yekuchengetedza capacitors uye snubber capacitors, zvikamu izvi zvinotora basa rakakosha mukudzikamisa nekuchengetedza magetsi kubva kuzvinhu zvakaita sevoltage spikes uye electromagnetic interference (EMI).
Kune mana makuru matopology e traction inverters, ane misiyano yakavakirwa pamhando yekuchinja, voltage uye mazinga.Kusarudza iyo yakakodzera topology uye zvinhu zvine hukama kwakakosha mukugadzira traction inverters inosangana nekushanda kwechishandiso chako uye mutengo zvinodiwa.
Sezvakataurwa, kune mana anonyanya kushandiswa topology muEV traction inverters, sezvinoratidzwa mumufananidzo 2.:
-
Level Topology ine 650V IGBT switch
-
Level Topology ine 650V SiC MOSFET switch
-
Level Topology ine 1200V SiC MOSFET switch
-
Level Topology ine 650V GaN Switch
Aya matopology anowira muzvikamu zviviri: 400V Powertrains & 800V Powertrains.Pakati pezvikamu zviviri, zvakajairika kushandisa "2-level" topology."Multi-level" topology anoshandiswa mumagetsi emagetsi epamusoro sezvitima zvemagetsi, tramways uye ngarava asi haanyanyozivikanwa nekuda kwekudhura uye kuoma.
-
Snubber Capacitors-Kudzivirirwa kwemagetsi kwakakosha kuchengetedza masekete kubva kune mahombe voltage spikes.Snubber capacitors inobatana kune yakakwirira-ikozvino switching node kuchengetedza zvemagetsi kubva kune voltage spikes.
-
DC-Link Capacitors- Mune EV zvikumbiro, DC-link capacitors inobatsira kugadzirisa mhedzisiro ye inductance mune inverters.Ivo zvakare vanoshanda semafirita anodzivirira EV subsystems kubva kune voltage spikes, surges uye EMI.
Ese aya mabasa akakosha kwazvo kuchengetedzeka uye kushanda kwe traction inverters, asi dhizaini uye zvirevo zveaya capacitors zvinoshanduka zvichibva pane iyo traction inverter topology yaunosarudza.
