Traction inverters for Siemens
- Client Siemens
- Location France
- Status In Progress
Modern traction inverters for Siemens vehicles Siemens’ new generation of lightrail vehicles is being introduced around the world. First locations that will see these fully automated vehicles in operation in 2020 are the city of Rennes and Bangkok airport.
Traction inverters are one of the core systems on board a train. Siemens want to have a technically strong and reliable partner to provide modern power electronic equipment. A partner willing and able to develop quality systems, willing to customise and able to competitively produce large and small series. The high safety demands for this crucial system further narrowed the choices for Siemens.
The 750Vdc input voltage is converted to 2x3 phase AC voltage to drive two Permanent Magnet (PM) motors. For this, 4 Power Modules (type 2N17-250) generate 8 phases. 6 legs for driving, 2 legs for dissipating brake energy if needed.
• Cost-efficient solution even for relatively small series projects
• A system developed with dual-sourcing strategy for key components (like IGBTs)
• Further deepening of the relationship between Siemens and Strukton
• Strukton again shows their ability to provide traction systems for refurbishment and in this case new trains
