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
