Knorr-Bremse Powertech converters are part of the four multi-voltage testing units, providing AC and DC supply voltages for external power supply to many different types of train. The required voltage and frequency are set for testing trains in either 3-phase or 1-phase operation. The test bench can thus be used to carry out tests and maintenance work on the trains with the components installed. Removal of the components for testing is not necessary. Also, depending on the vehicle type, each rail can be supplied differently.
The specialized power converters used on this application are part of the “Industry and Energy” power converter product line from Knorr-Bremse Powertech. The converter series’ flexible design enables deployment in a variety of applications: from energy-efficient automation and drive solutions, to solutions for the varying forms of power generation and high dynamic special applications. The converters consist of mains and drive converters in the power range of 50 kVA to 6000 kVA and up to 12 mW in parallel. These frequency converters thereby facilitate the complete simulation of technological processes in test bench applications. This helps to lower development costs substantially and dramatically speeds up development cycle time.
The first of four systems has completed commissioning with all voltage classes successfully implemented and numerous trains and train types tested. The final inspection on all four systems is planned for early 2016.
