Perfect solutions for individual trains
Modular platform solutions
Individually configured Siemens traction converters are based on highly developed platform solutions, supplied as either phase modules or as a complete converter unit.
All major voltage systems, either DC 750 V, 1,500 V and 3,000 V or the AC applications will be covered by two level inverters, equipped with IGBT's which are qualified for the rough conditions in traction applications.
All kinds of cooling are supported, for example water, external air and natural cooling.
Comfort and economy
The advanced Sitrac traction control system ensures minimal noise and vibration, sensorless speed control, and regenerative braking down to standstill.
Highly reliable converters featuring state-of-the-art IGBTs also ensure low operating costs and high efficiency.
By using silicon carbide (SiC) power semiconductors, various optimizations can be achieved in the traction system.
Key advantages of SiC devices include:
- Significantly higher switching frequencies
- Faster switching performance
- Higher junction temperatures
For example, with an appropriately designed transformer, transformer losses can be significantly reduced.
For battery-powered traction systems, SiC technology can also help increase the vehicle’s operating range.
High-tech and advanced methods
Traction converters from Siemens Mobility always provide the highest possible benefit – they are fitted with the latest tools to give our customers the assurance that these products are perfectly suited for the task at hand. By using the latest semiconductors, we ensure that our customers’ traction converters are well able to deal with high volumes and mass, and are equipped to deal with future challenges.
SIBAS – the optimal control for all types of trains
Successful worldwide
Â
SIBAS 32C was introduced in 2010 and has been fitted to 5,000 trains all over the world. It is used for the vehicle control units (VCU), as well as traction control units (TCU), brakes control units (BCU) and auxiliary power supplies (APS).
Powerful microprocessors compute both high volume realtime calculations, as well as processing the entire data provided by all of the train’s functions, including the coordination of subsystems. The control units are responsible for providing open-loop and closed-loop control, protecting onboard traction equipment near the converters and performing control and information tasks on a higher level for the entire train. Our integrated basic systems for traction and control meet all our customers’ requirements for utmost reliability and lowest life cycle costs.
