The Bordline CC400 series by ABB is dedicated for trams, metros, streetcars, trolleys, and monorails. The products provide CANopen connectivity.
In many cities and agglomerations, tramways and light rail vehicles are very popular. The Bordline CC440 traction system provides solutions to power such public transportation systems. The company has sold already more than 1000 converters. The products are installed for example in metro train-sets by Stadler Pankow, several trams, light rail vehicles by Vossloh, and tram-trains by Stadler Valencia.
The traction converters are suitable for roof, under-floor, and machine room mounting (monorail). The modular platform concept allows providing the complete power electronics (traction and auxiliary power) in one box. The CANopen-connectable products are optimized regarding weight and low-noise emission, claims the supplier.
The product converts the 600-VDC or 750-VDC line-voltage into propulsion power, which controls and drives the traction motors, and auxiliary power to supply the onboard loads. It is complemented by a modular energy storage system, including batteries, cooling, and battery management system. The converters comprise main-switch, line-filter, braking chopper, DC/DC converter, auxiliary converter, and control module. They can be directly coupled via CANopen to an energy storage system (ESS), which contains traction battery, cooling system, and energy management controller. The propulsion converter controls two motors and the braking chopper. During braking operation the energy can be stored in the ESS, recuperated to the grid or dissipated in the braking resistor. The cooling system uses liquid coolant. The battery unit is based on lithium cells.
The traction converters are built on the AC 800PEC control platform. A wide range of other industrial applications uses this control platform. The software supports different control and communication functionality, in cycle times that extend from the sub-microsecond to the millisecond level. It is optimized for train commissioning.
