Power converters
2. Power converters for electric vehicles
2.4. Design comparison of inverters for EV
Inverter for public transport vehicles
- IGBT technology
- Air-cooled inverter
- Bulky C filter on the DC side
- Bulky cooler
- The power of the inverter shown in the figure is approx. 10 - 20 kW
Three-phase inverter for electric vehicles supplied by trolley wire
Traction inverter for electric and hybrid cars
- SiC technology (however, IGBT or MOSFET is still the most widespread technology in electric cars)
- Liquid-cooled inverter
- Small C filter or none
- Small dimensions of the heatsink and the entire inverter (high power density)
- Power up to 200 kW
Three-phase inverter for traction battery powered vehicles
