Humidity in Traction Converters
In this report we will present a model to calculate the humidity inside railway traction converter cabinets based on the external conditions. With this the humidity related lifetime of IGBT modules can be calculated. The humidity model takes several physical effects into account like humidity absorption in plastic materials, adsorption on walls, condensation and absorption in wicking materials. We will show the correlation of the calculations with experiments.
New Traction Converter with Low Inductive High-Voltage Half Bridge IGBT Module
Traction systems for Rolling Stock are well suited for an overall system optimization. The innovation objectives are high reliability and availability as well as high energy efficiency, weight reduction and overall cost optimization including operational and maintenance costs. Today?s semiconductor and packaging innovation accompanied with a converter innovation promise significant traction system improvements. The following report will focus on the innovation of the Siemens traction converter platform SIBAC implementing design solutions, which meet recent traction system requirements. The converter platform is based on innovative semiconductors in a new half bridge package. All in all these converter and system innovations promote the attractiveness of public transport.
Nanocrystalline Cores for Common Mode Current Suppression in Electrical Ship Propulsion System - a Case Study
We introduce an electric ship propulsion system which appeared to be not conformal with EMC requirements for ships after installation. After analysis of electrical, mechanical and dimensional requirements and conditions, we developed oval shaped nanocrystalline cores for common mode suppression, being consistent with mechanical and thermal requirements in this special environment. The article presents the requirements, design of cores, and results in terms of common mode currents.
Discrete 1200V SiC MOSFETs - SMD Package Benefits and Impacts of Multiple Device and Circuit Parameters Mismatch in High Power Parallel Applications
The full benefits of SiC technology can be fully realized only when the device structure, package and application circuit parameters are all optimized.Several parameters impact the static, thermal and switching characteristics. This work focuses on the switching benefits of the new 1200V SiC MOSFETs,impact of several device parameters mismatch under parallel operation at high temperature,impact of gate driver and layout variations, prevention of parasitic (or shoot though) turn-on in bridge applications.
High-Dynamic High-Power E-Motor Emulator for Power Electronic Testing
Inverter testing has become a very important and complex issue during inverter developments. Especially automotive inverters offer multiple functions, high reliability, fault tolerance and must ensure a high level of functional safety. Conventional test methods such as motor test beds or active / passive RL-loads are not suitable to verify inverter functionalities in a sufficient manner. This paper presents a high-dynamic and powerful inverter testing technology: the E-Motor Emulator – testing power electronics without an e-machine.

Diagnostic Technique for Traction Motor Insulation Condition Monitoring by Transient Signal Assessment
Nominated for the Best Paper Award
Today's motor insulation in railway traction applications are operating very close to borderline of safe operation. The paper proposes an Online Insulation Monitoring Approach that is able to detect
incipient insulation defects - before breakdown by evaluation of the motor current. The paper presents experimental results of a 1.4 MW ASM traction motor for railway applications and investigations on accelerated aging applied on stator slot test fixtures with form-wound coils.
