   High efficiency High Reliability Inverter for Aeronautical Applications
By VIEILLARD SÃ©bastien [View]
[Download]

Abstract: In aerospace electrical systems, the design trade off is made by the optimization between 5 main constraints : efficiency, EMI, environment, integration level and reliability. In this paper is presented a power inverter solution that enables a high level of integration and a high level of efficiency. The integration of the power inverter is made in one single module that comprises 3 phase legs and one temperature measurement. This type of assembly enables to reduce the inverter volume by suppressing the use of discrete power components. The temperature cycling made revealed that this packaging assembly can withstand severe aeronautical environment. In the same time, the use of IGBT dies combined to SiC Schottky Diodes allows a 45 \% reduction on switching losses. The paper will present some tables that summarize the efficiency characterization done on the power module. Finally, this type of module will enable an easiest integration of the inverter in a complete controller environment with an improved reliability. Moreover this is done in a smaller whole volume due to the heat sink shrinking thanks to the improved efficiency.

Abstract: The paper investigates integrated series active filters to satisfy aircraft power quality benchmarks and underlying design compromises. Advantages include reduced component count and retrofitting capability. Further insights into the merits of the proposed solution are included, along with representative results from a prototype system.

   Research and test platform for hybrid electric vehicle with the super capacitor based energy storage
By CHENG Yonghua; LATAIRE Philippe; VAN MIERLO Joeri [View]
[Download]

Abstract: In this paper, the research and test platform for hybrid electric vehicle has been presented, which comprises power supply system, super capacitor based energy storage, traction system and the simulated load of vehicle. The strategies of energy sources control and management have been tested and verified in the standard speed cycle. The results show that the current of the power supply system (e.g. fuel cell) can be directly or indirectly controlled to be continuously changing. This feature can ensure good operating condition of power supply system. The test platform presented in this paper can be used for the further system test and optimization.
