Sistemụ eletriki eletrik dị na ụgbọ ala eletrik (EV) na-egosipụta ọtụtụ capacitors dị iche iche.
Site na DC-njikọ capacitors na nchekwa capacitors na snubber capacitors, ihe ndị a na-arụ ọrụ dị oke mkpa n'ịkwụsi ike na ichekwa ngwa eletrọnịkị site na ihe ndị dị ka spikes voltaji na nnyonye anya electromagnetic (EMI).
Enwere isi topologies anọ nke traction inverters, nwere ọdịiche dabere na ụdị mgba ọkụ, voltaji na ọkwa.Ịhọrọ topology kwesịrị ekwesị na ihe ndị yiri ya dị oke mkpa n'ịmepụta traction inverters na-emezu ngwa ngwa gị nke ọma yana ihe achọrọ.
Dịka ekwuru, enwere topologies anọ a na-ejikarị na EV traction inverters, dị ka egosiri na foto 2.:
-
Ọkwa Topology na-egosipụta mgba ọkụ 650V IGBT
-
Ọkwa Topology na-egosipụta mgba ọkụ 650V SiC MOSFET
-
Ọkwa Topology na-egosipụta mgba ọkụ 1200V SiC MOSFET
-
Ọkwa Topology na-egosipụta 650V GaN Switch
Topologies ndị a dabara na mpaghara abụọ: 400V Powertrains & 800V Powertrains.N'etiti nkeji abụọ a, ọ na-adịkarịkarị iji topologies "2-level".A na-eji topologies “Multi-level” na sistemụ voltaji dị elu dị ka ụgbọ oloko eletrik, tram na ụgbọ mmiri mana ha amachaghị ewu ewu n'ihi ọnụ ahịa dị elu na mgbagwoju anya.

Snubber Capacitors- Mbelata voltaji dị mkpa iji chebe sekit site na nnukwu voltaji spikes.Snubber capacitors jikọọ na ọnụ mgbanwe mgbanwe dị ugbu a iji kpuchido eletrọnịkị site na spikes voltaji.
-
DC-Link Capacitors- N'ime ngwa EV, DC-njikọ capacitors na-enyere aka ịkwụsị mmetụta nke inductance na inverters.Ha na-ejekwa ozi dị ka nzacha na-echebe EV subsystems si voltaji spikes, surges na EMI.
Ọrụ ndị a niile dị ezigbo mkpa maka nchekwa na arụmọrụ nke traction inverters, mana nhazi na nkọwapụta nke capacitors ndị a na-agbanwe dabere na traction inverter topology ị họọrọ.
