Cov tshuab hluav taws xob hauv lub tsheb fais fab (EV) muaj ntau yam capacitors.
Txij li cov DC-link capacitors mus rau cov capacitors kev nyab xeeb thiab snubber capacitors, cov khoom no ua lub luag haujlwm tseem ceeb hauv kev ruaj khov thiab kev tiv thaiv cov khoom siv hluav taws xob los ntawm cov yam xws li voltage spikes thiab electromagnetic interference (EMI).
Muaj plaub lub ntsiab lus tseem ceeb ntawm cov traction inverters, nrog rau qhov sib txawv raws li hom hloov, voltage thiab theem. Kev xaiv cov topology tsim nyog thiab cov khoom cuam tshuam yog qhov tseem ceeb hauv kev tsim cov traction inverters uas ua tau raws li koj daim ntawv thov qhov ua tau zoo thiab cov nqi xav tau.
Raws li tau hais lawm, muaj plaub lub topologies uas siv ntau tshaj plaws hauv EV traction inverters, raws li pom hauv Daim Duab 2.:
-
Qib Topology uas muaj qhov hloov IGBT 650V
-
Qib Topology uas muaj 650V SiC MOSFET hloov
-
Qib Topology uas muaj 1200V SiC MOSFET hloov
-
Qib Topology uas muaj 650V GaN Switch
Cov topologies no poob rau hauv ob pawg me me: 400V Powertrains & 800V Powertrains. Nruab nrab ntawm ob pawg me me, nws yog ib qho uas siv ntau dua "2-level" topologies. "Multi-level" topologies yog siv rau hauv cov kab ke hluav taws xob siab dua xws li tsheb ciav hlau hluav taws xob, tramways thiab nkoj tab sis lawv tsis tshua muaj neeg nyiam vim yog tus nqi siab dua thiab qhov nyuaj.

Cov Capacitors Snubber- Kev tswj hwm hluav taws xob yog qhov tseem ceeb los tiv thaiv cov circuits ntawm cov hluav taws xob loj heev. Cov capacitors Snubber txuas rau lub qhov hloov pauv siab kom tiv thaiv cov khoom siv hluav taws xob ntawm cov hluav taws xob loj heev.
-
Cov Capacitors DC-Link- Hauv cov ntawv thov EV, Cov capacitors DC-link pab txo cov teebmeem ntawm inductance hauv inverters. Lawv kuj ua haujlwm ua cov lim dej uas tiv thaiv EV subsystems ntawm voltage spikes, surges thiab EMI.
Tag nrho cov luag haujlwm no tseem ceeb heev rau kev nyab xeeb thiab kev ua haujlwm ntawm cov traction inverters, tab sis tus qauv tsim thiab cov lus qhia ntawm cov capacitors no hloov pauv raws li cov traction inverter topology uas koj xaiv.
