Insulated Gate Bipolar Transistors (IGBTs) are today's state-of-the-art power electronics for the traction system of electric (and diesel-electric) rail vehicles. They replace the previous inverter generation represented by GTO (gate turn-off thyristors).

Vehicle - fix costs: low |
|
|
|
|
|
IGBT drive technology is a mature technology in rail vehicles. It does not substantially increase the vehicle price compared GTO or other technology. |

Scale effects: low |
|
|
|
|
|
Scale effects within railways have already been exploited. Scale effects from mass markets are unlikely since the specifications (e.g. blocking voltage) for railway IGBTs require dedicated development and production. |
