Sistemụ eletrọniki ike dị n'ụgbọala eletrik (EV) nwere ọtụtụ capacitors dị iche iche.
Site na DC-link capacitors ruo na nchekwa capacitors na snubber capacitors, ihe ndị a na-arụ ọrụ dị oke mkpa n'ịkwụsi ike na ichekwa eletrọniki site na ihe dịka voltaji spikes na electromagnetic nnyonye anya (EMI).
E nwere isi ihe anọ dị mkpa nke inverters traction, nke nwere ọdịiche dabere na ụdị switch, voltaji na ọkwa. Ịhọrọ topology kwesịrị ekwesị na ihe ndị metụtara ya dị oke mkpa n'ịmepụta inverters traction nke na-emezu arụmọrụ na ihe achọrọ maka ngwa gị.
Dịka ekwuru, enwere topologies anọ a na-ejikarị eme ihe na inverters traction EV, dịka egosiri na Foto 2.:

Ọkwa Topology nke nwere mgba ọkụ IGBT 650V
-
Ọkwa Topology nke nwere mgba ọkụ 650V SiC MOSFET
-
Ọkwa Topology nke nwere mgba ọkụ 1200V SiC MOSFET

Ọkwa Topology nke nwere 650V GaN Switch
Usoro ndị a dabara n'ime usoro abụọ: Usoro ndị nwere ike ịgafe 400V na usoro ndị nwere ike ịgafe 800V. N'etiti usoro abụọ a, ọ na-abụkarị iji usoro ndị nwere ike ịgafe 2. A na-eji usoro ndị nwere ike ịgafe 2000 "ọtụtụ ọkwa" eme ihe na sistemụ voltaji dị elu dịka ụgbọ okporo ígwè eletrik, ụzọ ụgbọ okporo ígwè na ụgbọ mmiri mana ha anaghị ewu ewu nke ukwuu n'ihi ọnụ ahịa na mgbagwoju anya dị elu.

Ndị na-enye ikike Snubber– Mbelata voltaji dị mkpa iji chebe sekit site na nnukwu oghere voltaji. Ndị na-eme ka capacitors na-ejikọ na ebe mgbanwe ọkụ eletrik dị elu iji chebe eletrọniki site na oghere voltaji.

Ndị na-enye DC-Link Capacitors– Na ngwa EV, Ike njikọ DC na-enyere aka belata mmetụta nke inductance na inverters. Ha na-ejekwa ozi dị ka nzacha nke na-echebe sistemụ EV site na mmụba voltaji, mmụba na EMI.
Ọrụ ndị a niile dị oke mkpa maka nchekwa na ọrụ nke inverters traction, mana nhazi na nkọwapụta nke capacitors ndị a na-agbanwe dabere na ụdị traction inverter topology ị họọrọ.
