   A new Family of Modular IGBT Converters for Traction Applications
By NAGEL Andreas; BAKRAN Mark; ECKEL Han; KRAFFT Eberhard [View]
[Download]

Abstract: Electrical locomotives and trains are nowadays driven by asynchronous motors, which are fed by voltage source inverters. The IGBT two level inverter allows a standardization of the topology and the control strategy over the whole power and voltage range. However, different application conditions (cooling, dc-link voltage, power range) lead to different converters. To allow a flexible converter design with proven components, a family of power electronic building blocks was developed, which uses 3.3kV and 6.5kV IGBT and achieves an output power of up to 3MW.

   New Generation of Compact Low Voltage IGBT Converter for Traction Applications
By KNAPP Gerold; NOLD Armando; DAEHLER Peter [View]
[Download]

Abstract: This paper deals with innovative compact converters for use in local transit vehicles. Utilising the latest generation of low voltage IGBT modules [1], a compact and low cost design of the entire converter system is achieved. Due to the high switching frequency of IGBTs a simple PWM modulation strategy can be applied with no need of complex transitions between different modulation strategies. The control system is set up with a new in-house platform (OPCoDe platform) using FPGA technology at a high speed level (< 25 ms) and a slower MATLAB®/Simulink® based programming environment at lower speed levels (50 ms range and slower). Thanks to these advanced tools, high-quality software can be provided and modifications can be easily carried out, even during operation.

   Parameter Estimation for Traction Drive-Trains
By FLEISCHER Michael [View]
[Download]

Abstract: The traction drive-train of rail vehicles consists of a flexiblemulti-inertia system subject to rubber aging and wheel wear. Forsystem monitoring purposes, those two effects are decoupledenabling precise estimation of the variable mechanical parameters,namely the rubber joint stiffness and the wheel disc radius, onthe basis of an identified modal three-inertia model.
