Power Converter Cubicle (PCC)
Toshiba’s traction converters (“Power Converter Cubicles”, PCC) are specifically designed for installation on railway vehicles. To minimize interfaces, all essential functions are housed in the PCC, allowing the module to be easily removed from the vehicle for maintenance.

Features
Toshiba traction converters include:
- AC/DC converter (3-phase when feeding generators or as four-quadrant chopper)
- DC/AC inverter (traction motor supply)
- Auxiliary converter
- Battery charger
- External feed for charging a traction battery (400 V 3 ph)
- External feed for charging an on-board battery via battery charger (230 V)
- Interface to traction battery system in order to store energy of recuperation
- Internal or external cooling
