Iinkqubo ze-elektroniki zamandla kwisithuthi sombane (i-EV) zineentlobo ngeentlobo zee-capacitors.
Ukususela kwii-capacitors ze-DC-link ukuya kwii-capacitors zokhuseleko kunye nee-capacitors ezingenanto, ezi nxalenye zidlala indima ebalulekileyo ekuzinziseni nasekukhuseleni izixhobo ze-elektroniki kwizinto ezifana nokuqhekeka kwe-voltage kunye nokuphazamiseka kwe-electromagnetic (EMI).
Kukho iitopoloji ezine eziphambili zee-traction inverters, ezahlukeneyo ngokusekelwe kuhlobo lweswitshi, i-voltage kunye namanqanaba. Ukukhetha i-topology efanelekileyo kunye nezinto ezinxulumene nayo kubalulekile ekuyileni ii-traction inverters ezihlangabezana nokusebenza kakuhle kwesicelo sakho kunye neemfuno zeendleko.
Njengoko bekutshiwo, kukho iitopoloji ezine ezisetyenziswa kakhulu kwii-inverters ze-EV traction, njengoko kubonisiwe kuMfanekiso 2.

I-Level Topology ene-650V GaN Switch
Ezi topoloji zahlulwe zibe zii-subset ezimbini: ii-Powertrains ezingama-400V kunye nee-Powertrains ezingama-800V. Phakathi kwezi subset zimbini, kuqheleke kakhulu ukusebenzisa ii-topology “zezinga eli-2”. Ii-topology “zezinga eli-Multi” zisetyenziswa kwiinkqubo ze-voltage eziphezulu ezifana noololiwe bombane, iitram kunye neenqanawa kodwa azithandwa kangako ngenxa yeendleko eziphezulu kunye nobunzima.

Ii-Capacitors ze-Snubber– Ukunciphisa i-voltage kubalulekile ukukhusela iisekethe kwii-spikes ezinkulu ze-voltage. Ii-snubber capacitors ziqhagamshela kwi-node yokutshintsha yamandla aphezulu ukukhusela ii-elektroniki kwii-spikes ze-voltage.

Ii-DC-Link Capacitors- Kwizicelo ze-EV, Ii-capacitors ze-DC-link zinceda ekunciphiseni imiphumo ye-inductance kwii-inverters. Zikwasebenza njengezihluzi ezikhusela ii-subsystems ze-EV kwi-voltage spikes, surges kunye ne-EMI.
Zonke ezi ndima zibaluleke kakhulu kukhuseleko kunye nokusebenza kwee-traction inverters, kodwa uyilo kunye neenkcukacha zezi capacitors ziyatshintsha ngokusekelwe kwi-topology ye-traction inverter oyikhethayo.
