Iinkqubo ze-elektroniki zamandla kwisithuthi sombane (EV) zibandakanya iindidi ezininzi ze-capacitors.
Ukusuka kwii-DC-link capacitors ukuya kwii-capacitors zokhuseleko kunye nee-snubber capacitors, la macandelo adlala indima ebalulekileyo ekuzinziseni nasekukhuseleni izinto zombane kwizinto ezifana ne-voltage spikes kunye nokuphazamiseka kwe-electromagnetic interference (EMI).
Kukho ii-topology ezine eziphambili ze-inverters ze-traction, kunye nokwahlukana ngokusekelwe kuhlobo lokutshintsha, i-voltage kunye namanqanaba.Ukukhetha i-topology efanelekileyo kunye namacandelo anxulumeneyo kubalulekile ekuyileni ii-inverters ze-traction ezihlangabezana nokusebenza kakuhle kwesicelo sakho kunye neemfuno zeendleko.
Njengoko kukhankanyiwe, kukho iitopology ezine ezisetyenziswa kakhulu kwi-EV traction inverters, njengoko kubonisiwe kuMfanekiso 2.

I-Level Topology ene-650V IGBT switch
-
I-Level Topology ene-650V SiC MOSFET iswitshi
-
I-Level Topology ene-1200V SiC MOSFET iswitshi
-
I-Level Topology ene-650V GaN Switch
Ezi topology ziwela kwiiseti ezimbini: 400V Powertrains & 800V Powertrains.Phakathi kweeseti ezimbini ezisezantsi, kuxhaphake kakhulu ukusebenzisa i-"2-level" topology.I-"Multi-level" i-topology isetyenziswa kwiinkqubo zamandla ombane aphezulu ezifana noololiwe bombane, iitramways kunye neenqanawa kodwa azithandwa kangako ngenxa yeendleko eziphezulu kunye nobunzima.

Snubber Capacitors-Uxinzelelo lwe-voltage lubalulekile ukukhusela iisekethe kwi-spikes enkulu yombane.I-Snubber capacitors idibanisa kwi-node ephezulu yokutshintsha ukukhusela i-electronics kwi-voltage spikes.

I-DC-Link Capacitors-Kwizicelo ze-EV, I-DC-link capacitors inceda ukucima imiphumo ye-inductance kwi-inverters.Zikwasebenza njengezihluzi ezikhusela ii-subsystems ze-EV kwi-voltage spikes, i-surges kunye ne-EMI.
Zonke ezi nxaxheba zibaluleke kakhulu kukhuseleko kunye nokusebenza kwee-inverters ze-traction, kodwa ukuyila kunye neenkcukacha zala ma-capacitors atshintsha ngokusekelwe kwi-inverter topology ye-traction oyikhethayo.
