| Abstract |
The new generation of the high-voltage insulated gate bipolar transistors (HVIGBT) with high current carrying capabilities makes feasible high power applications with an improved performance and higher reliability for power conversion. For the power supply of the variable-frequency railway network rotating system tie frequency converters with the rated power range of 20 up to 50 MW are used. A rotating system tie frequency converter consists of a slip ring induction machine, which has to be rated only for the slip power (less than 5 % of the rated transfer power) on the rotor side. The new proposed concept of a rotating system tie frequency converter with the rated power of 25 MW, in general to be found in power delivering for the German, Swiss and Austrian railway organisation, has an Active Front End (AFE) converter with HVIGBT as a voltage source DC-link converter. Power circuit, power transfer under steady-state and transient conditions and the running up procedure are described. |
