Tsarin wutar lantarki a cikin abin hawan lantarki (EV) yana da nau'ikan capacitors iri-iri.
Daga DC-link capacitors zuwa aminci capacitors da snubber capacitors, waɗannan abubuwa suna taka muhimmiyar rawa wajen daidaitawa da kiyaye kayan lantarki daga abubuwa kamar ƙarfin lantarki da tsangwama na lantarki (EMI).
Akwai manyan topologies guda huɗu na masu juyawa, tare da bambance-bambance dangane da nau'in canji, ƙarfin lantarki da matakan.Zaɓin abubuwan da suka dace da topology da abubuwan da ke da alaƙa yana da mahimmanci a ƙirƙira inverter na jujjuyawa waɗanda suka dace da ingancin aikace-aikacenku da buƙatun farashi.
Kamar yadda aka bayyana, akwai topologies guda huɗu da aka fi amfani da su a cikin EV traction inverters, kamar yadda aka nuna a hoto 2.:
-
Matsayin Topology wanda ke nuna 650V IGBT sauyawa
-
Matsayin Topology wanda ke nuna 650V SiC MOSFET sauyawa
-
Matsayin Topology wanda ke nuna canjin 1200V SiC MOSFET
-
Matsayin Topology wanda ke nuna 650V GaN Switch
Wadannan topologies sun fada cikin rukunoni biyu: 400V Powertrains & 800V Powertrains.Tsakanin ɓangarori biyu, ya fi zama gama gari don amfani da topologies “mataki biyu”.Ana amfani da topologies na “Multi-Level” a cikin mafi girman tsarin wutar lantarki kamar jiragen kasa na lantarki, titin jirgin ƙasa da jiragen ruwa amma ba su da farin jini saboda tsada da rikitarwa.

Snubber Capacitors- Damuwar wutar lantarki yana da mahimmanci don kare da'irori daga manyan fitattun wutar lantarki.Snubber capacitors suna haɗi zuwa babban kullin sauyawa na yanzu don kare na'urorin lantarki daga magudanar wutar lantarki.

DC-Link Capacitors- A cikin aikace-aikacen EV, DC-link capacitors suna taimakawa wajen daidaita tasirin inductance a cikin inverters.Hakanan suna aiki azaman masu tacewa waɗanda ke kare tsarin tsarin EV daga ƙawancen wutar lantarki, hawan jini da EMI.
Duk waɗannan ayyuka suna da mahimmanci sosai ga aminci da aiki na masu inverter, amma ƙira da ƙayyadaddun waɗannan capacitors suna canzawa dangane da wane nau'in inverter topology kuka zaɓa.
