   Design and development of a 1MVA Medium Voltage IGCT-based converter set-up

Abstract: This paper presents the design and development of a 1MVA medium voltage IGCT-based converter set-up. The set up is rated at 2.5kV and a maximum output current of 1kA. The paper describes the most relevant aspects in the design process, such as the clamp design, layout definition, cooling system, etc, and presents its use for the study of a particular converter topology: a single phase H Bridge. Power losses and thermal behavior have been first studied in Matlab-Simulink and then validated by experimental results.

   Combined Optimisation of Thermal Behaviour and Electrical Parasitics in Power Semiconductor Components
By Stefan FÃ–RSTER, Andreas LINDEMANN [View]
[Download]

Abstract: Capacitive and inductive parasitics that exist in every electrically conducting structure are inseparably associated with the geometry. Especially in power electronic systems the geometry also is defined through thermal aspects. Investigation of the correlation between thermal optimisation of the electrically conduction structure and the influence of this reshape process on the formation of capacitive and inductive parasitics is the main task. The work aims on a combined optimisation process. Therefor PEEC (partial element equivalent circuit) method is employed to extract parasitics as lumped parameters for an adequately subdivided current path under view. Approaches for methodical application in design processes are studied.

   Selecting an optimum number of system phases for an integrated, fault tolerant permanent magnet machine and drive
By Johan WOLMARANS, Henk POLINDER, Bram FERREIRA, Dave CLARENBACH [View]

Abstract: Aerospace systems require high power density as well as high availability. An integrated permanent magnet machine and drive has been considered. System integration aids achieving high power density in aerospace applications whereas fault tolerance increases availability, mostly by increasing system phase count. This increase in the number of system phases has certain, differing effects on various elements of the design. To facilitate fault tolerance, unity inductance is required, which is also taken into account in the analysis. Key system losses are considered. By analyzing these key system design elements in the electrical machine and drive, an optimal phase count can be derived.
