The objective of this post-doctorate is to study and quantify the impact of a power converter on the design and sizing of an electric traction machine.
- Use of software tools internal to the PSA Group and / or the laboratory.
-Study, modeling and characterization on a bench of an PSA electric traction machine. The aim is to compare the simulations to experimental results. The machine will be at first powered by a conventional power converter and control laws. Works on this part have already been carried out and will serve as a starting point.
- Characterization by simulation and experimentation of the Ibis unit coupled with the machine previously tested.
-Redesign of the PSA machine according to the specifications imposed by Ibis. In this part, the aim will be to improve the efficiency and important features of the machine (noise, winding, etc.)
The candidate must have solid knowledge in modeling and design of electrical machines as well as in electrical power conversion structures. Experimentation skills will be welcome. The candidate will be integrated into the IBIS project team which brings together French strategic industrialists linked to the development of electromobility (PSA Group, SAFT-TOTAL, E2CAD and Sherpa Engineering). The candidate will therefore have very good teamwork skills.
Global warming, with its environmental consequences, pollution in cities and the foreseeable exhaustion of fossil liquid fuels are among the major concerns of our modern societies. The challenge for the automotive industry is therefore to develop innovative and economical technologies to offer vehicles that emit little or no polluting gases on the market.
It is within this framework that the IBIS project (Intelligent Battery Integrated System ) was initiated. Supported by ADEME and coordinated by the PSA Group, the IBIS project aims to develop an innovative inverter-charger-battery unit, marking a major break compared to conventional electrical energy conversion chains. It should make it possible to reduce the manufacturing cost of the vehicle, to optimize the volume of the power converter and of the whole traction chain and also to offer additional degrees of freedom for the design and optimization of electric traction machines.
Constraints and risks
Experimental tests will be carried out on an 60 kW electrical machine with associated battery and converter.
