Lub tshuab hluav taws xob hluav taws xob hauv lub tsheb hluav taws xob (EV) muaj ntau yam khoom siv hluav taws xob.
Los ntawm DC-link capacitors mus rau kev nyab xeeb capacitors thiab snubber capacitors, cov khoom no ua lub luag haujlwm tseem ceeb hauv kev ruaj khov thiab tiv thaiv cov khoom siv hluav taws xob los ntawm cov yam ntxwv xws li hluav taws xob hluav taws xob thiab hluav taws xob cuam tshuam (EMI).
Muaj plaub lub ntsiab lus tseem ceeb ntawm traction inverters, nrog qhov sib txawv raws li hom kev hloov, voltage thiab qib.Xaiv qhov tsim nyog topology thiab cov khoom muaj feem cuam tshuam yog qhov tseem ceeb hauv kev tsim traction inverters uas ua tau raws li koj daim ntawv thov kev ua tau zoo thiab cov nqi xav tau.
Raws li tau hais, muaj plaub feem ntau siv topologies hauv EV traction inverters, raws li qhia hauv daim duab 2.:
-
Theem Topology featuring 650V IGBT hloov
-
Theem Topology featuring 650V SiC MOSFET hloov
-
Qib Topology featuring 1200V SiC MOSFET hloov
-
Theem Topology featuring 650V GaN Hloov
Cov topologies no poob rau hauv ob lub subsets: 400V Powertrains & 800V Powertrains.Nyob nruab nrab ntawm ob lub subsets, nws muaj ntau dua los siv "2-theem" topologies."Multi-level" topologies yog siv hauv cov tshuab hluav taws xob siab dua xws li tsheb ciav hlau hluav taws xob, tramways thiab nkoj tab sis lawv tsis tshua nyiam vim yog tus nqi siab dua thiab nyuaj.
-
Snubber Capacitor- Kev tiv thaiv hluav taws xob yog qhov tseem ceeb los tiv thaiv circuits los ntawm cov hluav taws xob loj.Snubber capacitors txuas mus rau high-tam sim no switching node los tiv thaiv electronics los ntawm voltage spikes.
-
DC-Txuas Capacitor- Hauv kev siv EV, DC-link capacitors pab cuam tshuam qhov cuam tshuam ntawm inductance hauv inverters.Lawv kuj ua cov lim dej uas tiv thaiv EV subsystems los ntawm qhov hluav taws xob nce siab, nce siab thiab EMI.
Tag nrho cov luag haujlwm no tseem ceeb heev rau kev nyab xeeb thiab kev ua haujlwm ntawm traction inverters, tab sis cov qauv tsim thiab cov kev qhia tshwj xeeb ntawm cov capacitors hloov pauv raws li qhov twg traction inverter topology koj xaiv.
