“Foster innovation of electrical energy conversion for sustainable transport”

The Power Technologies & Integration Competence Center aims to respond to the challenges of a switch to electric vehicles which, to be competitive with other energies (pneumatic, hydraulic, etc.), must find a way to increase the power density of electrical systems. Moreover, the whole set of technologies and design methods need to be revised to:

– increase the voltage to reduce the cable mass,

– use higher performance electronic components (wide gap components) to reduce losses,

– a better integration of the components and equipment in order to master mass constraints, electromagnetic compatibility (CEM), network quality, reliability, thermal control or costs.

 

The competence center concentrates on electromechanical conversion chains, electronic power converters and electric motors, developing technologies (power modules, filters, inductances, printed circuit board, drivers, thermals, materials, etc.) and the methodologies required to optimize them (MDO/MDA) on different criteria (mass, thermal control, CEM, etc.). This means helping increase the power density of electronic circuits of between 2 to over 10 kilowatts/kg and of electric machines of between five to over 15 kilowatts/kg. The competence center deals with voltages of less than a kilovolt for applications of a few hundred kilowatts (small carriers) to voltages of between 1 and 3 kilovolts for applications of over a million watts (propulsion, major carriers).

R&T Fields

The competence center produces demonstrators and prototypes of electric sub-systems in three power ranges:

  • A few hundred watts for more integrated supply systems
  • A few kilowatts to 50 kilowatts for non-propulsive applications
  • Over 100 kilowatts for propulsive applications

It masters all the parameters of the subjects of its studies to verify performance of the electrical systems depending on their application. Several actors worldwide work on the individual optimization of the components but the IRT Saint Exupéry, the company common to aircraft manufacturers, systems engineers, equipment manufacturers and technology producers, facilitates integration of the different constraints so that overall optimization can be achieved.

The competence center develops new technologies to produce demonstrators and validates performance of an unavailable technology on a controlled demonstrator. This is done through management of thermal factors, power modules, components of electronic power cores (drivers, filters, etc.) and electric machines. The additive manufacturing potential for electric engineering is also explored.
It is essential that the tools and methods are effectively controlled to provide support to industrialists in the preliminary phases of design or of the design phase itself. These are the underlying technological building blocks and electrical subsets, like the electromechanical chains that need to be more closely controlled and optimized across the board and not just locally as is the case today.
