Mphamvu zamagetsi zamagetsi mugalimoto yamagetsi (EV) zimakhala ndi ma capacitor osiyanasiyana.
Kuchokera ku ma DC-link capacitor kupita ku ma capacitor otetezeka ndi ma snubber capacitor, zigawozi zimagwira ntchito yofunika kwambiri pakukhazikika ndi kuteteza zamagetsi kuzinthu monga ma spikes amagetsi ndi kusokoneza kwa electromagnetic (EMI).
Pali ma topology anayi akuluakulu a ma traction inverters, omwe amasiyana malinga ndi mtundu wa switch, voltage ndi milingo.Kusankha topology yoyenera ndi zida zofananira ndizofunikira pakupanga ma traction inverters omwe amakwaniritsa magwiridwe antchito anu komanso mtengo wake.
Monga tafotokozera, pali ma topology anayi omwe amagwiritsidwa ntchito kwambiri mu ma EV traction inverters, monga akuwonetsera Chithunzi 2.

Level Topology yokhala ndi 650V IGBT switch
-
Level Topology yokhala ndi 650V SiC MOSFET switch
-
Level Topology yokhala ndi 1200V SiC MOSFET switch
-
Level Topology yokhala ndi 650V GaN switch
Ma topology awa amagwera m'magulu awiri: 400V Powertrains & 800V Powertrains.Pakati pa magawo awiriwa, ndizofala kugwiritsa ntchito mitu ya "2-level"."Multi-level" topologies amagwiritsidwa ntchito m'makina okwera magetsi monga masitima apamtunda amagetsi, ma tramways ndi zombo koma sadziwika chifukwa cha kukwera mtengo komanso zovuta.

Snubber Capacitors- Kuchepetsa mphamvu yamagetsi ndikofunikira kuti muteteze mabwalo ku ma spikes akulu akulu.Ma snubber capacitor amalumikizana ndi njira yosinthira yanthawi yayitali kuti ateteze zamagetsi ku ma spikes amagetsi.
-
DC-Link Capacitors- M'mapulogalamu a EV, DC-link capacitors amathandizira kuthetsa zotsatira za inductance mu inverters.Amagwiranso ntchito ngati zosefera zomwe zimateteza ma EV subsystems ku ma spikes amagetsi, ma surges ndi EMI.
Maudindo onsewa ndi ofunikira kwambiri pachitetezo ndi magwiridwe antchito a traction inverters, koma mapangidwe ndi mafotokozedwe a ma capacitor awa amasintha kutengera zomwe mumasankha traction inverter topology.
