POWER4AIR

Solutions for improved electronic power conversion in aeronautics 

The european research project POWER4AIR is developing innovative technologies for a safe, efficient and reliable power supply in the aviation sector. The aim is to enable the next generation of power electronics for aviation, in particular through advanced HVDC (high-voltage direct current) power distribution. The focus is on developing robust reliability models for modern wide-bandgap power semiconductors (SiC, GaN), the early detection of arcing and partial discharges, and compact, active filter solutions to reduce electromagnetic interference (EMI). The solutions developed are being prototyped in a 250 kW power inverter and tested under realistic conditions.

The project is helping to drive forward the electrification of aviation, reduce weight and maintenance requirements, and enhance the safety of future aircraft platforms. 

POWER4AIR is supported by a strong consortium of leading research institutions, universities and industry partners. The project partners include Skylife Engineering (Spain, coordinator), IRT Saint Exupéry (France), Fraunhofer IISB and IMWS (Germany), SINTEF Energi (Norway), Universidad Carlos III de Madrid, Universidad de Sevilla and CEIT (all in Spain), as well as the associated partners ATR (France) and STMicroelectronics (France).

Fraunhofer IISB contributes to the project including:

Work Package 1: Power Electronics Reliability

  • Development and validation of reliability models, as well as service life tests for SiC power modules
  • Support with failure analysis and modelling for digital twins and health monitoring
  • Our partner institute Fraunhofer IMWS provides support by contributing its technological expertise in the field of materials testing

Work Package 3: High Density Filtering

  • Development of a hybrid CM EMI filter for aerospace applications to effectively reduce interference with offering a weight advantage over conventional passive solutions
  • Validation of the filter performance under operating and environmental conditions; integration of the developed hybrid EMI filter into a 250 kW motor control unit in accordance with aerospace EMC standards (DO-160)

Within the POWER4AIR project, Fraunhofer IISB plays a central role in the development of reliable, long-lasting power modules, as well as in the development and testing of highly compact, active/hybrid CM EMI filter solutions. In doing so, IISB is making a vital contribution to the safe, efficient and sustainable electrification of aviation.
