Offer Description
Work context
Presentation of the CNRS
The mission of the National Centre for Scientific Research (CNRS) is to leverage all fields of sciences to tackle current global challenges. (https://www.cnrs.fr/en/the-cnrs/missions )
The subject comes under section 8 of the CNRS: Micro- and nanotechnologies, micro- and nanosystems, photonics, electronics, electromagnetism, electrical energy.
Presentation of the laboratories
The work will be carried out for 24 months within the EE department of the Ampère Laboratory (UCBL/Ampère, Bat Omega, 43 Boulevard du 11 Novembre 1918, 69622 Villeurbanne) and the last 12 months at IREENA (37, boulevard de l'université CS 90406, 44612 Saint-Nazaire).
- Ampere Laboratory (UMR5005)
Internet address : http://www.ampere-lab.fr/
The AMPERE Laboratory focuses on the rational management and use of energy in systems while considering their environment. To that purpose, it develops disciplinary and trans-disciplinary activities through its three departments and six priorities. The departments are centred in the scientific disciplines, and are the backbone of the laboratory: automation for system engineering (AIS, or Automatique pour l'Ingénierie des Systèmes, in French), Bio-engineering (BIO) and Electrical Engineering (EE). The six priorities foster trans-disciplinary activities, and are redefined on a regular basis, to accommodate new topics or societal needs, which may arise. On 17/5/2021, it has 185 members, including 83 PhD students and 75 academics. AMPERE develops strong relationships with Supergrid Institute. AMPERE has extensive experience in the field of power electronics and health monitoring. It has many experiment platforms including an OPAL-RT Hardware-in-The-Loop platform and the Grid4Mobility bench enabling to prototype control algorithm for DC-DC converters on a possible mesh DC grid with PV module and electric vehicle charging.
- LabEcam
The laboratory is composed of 14 teacher-researchers (including 1 HDR), 4 engineers/technicians and a dozen doctoral or post-doctoral students. Its annual budget is of the order of one million euros. The lab field is declined according 4 main axes:
Theme 1: Thermal, efficiency and lubrication of mechanical transmission systems
Theme 2: Materials and processes of transmission parts
Theme 3: Durability of contact materials
Theme 4: Monitoring of electromechanical transmission chains
These research activities are very applied to the industrial field and are mainly based on the work of doctoral students with CIFRE status (SAFRAN Chair in partnership with LaMCoS, CIRTRANS consortium, TRANSMECA laboratory…)
In the transport sector, industrial challenges are today pushing our partners to consider more and more so-called “eDrive” systems including a “Transmission + Engine + Power electronics”. This approach will allow the laboratory to extend its “electrical” and its predictive maintenance skills in transmissions into the complete chain study.
- IREENA - UR 4642
The Institut de Recherche en Energie Electrique de Nantes Atlantique, based at the Saint-Nazaire site, has a staff of 65 people, including 24 teacher-researchers, 2 associate researchers, 1 emeritus professor, 6 post-doctoral students, 2 IATSS, 2 research engineers and 22 PhD students. The permanent staff are attached to Polytech Nantes, IUT Saint-Nazaire, IUT La Roche-sur-Yon, ICAM and ESEO Angers. IREENA conducts upstream research aimed at applications that can address societal challenges such as the safety and reliability of electrical components and systems, energy efficiency for sustainable development, renewable energies, particularly marine energies, and the industry of the future. The solutions proposed adopt a systems approach supported by original modelling approaches. The laboratory's main fields of application are transport (naval, aeronautical, automotive), sustainable energy management (offshore wind, tidal) and Smartgrids (housing, energy mix).
Presentation of the PHD school
The candidate will be enrolled in the EEA Doctoral School.
The EEA Doctoral School in Lyon is one of 17 thematic Doctoral Schools attached to the institutions that make up the University of Lyon. It brings together all the laboratories and researchers in the field of Electronics, Electrical Engineering, Automation and Signal Processing in the Lyon Saint Etienne area.
Planning and organisation of work
The different work package are:
First 2 year - Villeurbanne
• WP2.2.1 : State of art on the failure mechanisms of SiC modules (MOSFET ones or IGBT modules if avalilable for 1200V/150A ratings) and their TSEPs.
• WP2.2.2 : Determinaton of the appropriate Tsep via accelerating aging tests. One of the Locks is: Given the switching times, some parameters are no longer reasonably detectable (Miller plateau, etc.). These parameters will be determined using an ageing bench.
Third years – St Nazaire
• WP2.2.3 Monitoring the health of the converters via sensors and observers, to evaluate the temperature sensitive electrical parameters (TSEP) and trace them back to the junction temperature. One of the locks is to get back to the junction temperature from Tsep. One of the ideas would be to use an inverse model that should be identified and/or observed (extended observer). To do this, the geometry and thermal properties of the module must be considered and the model obtained must be validated by measurements, for example by optical fiber.
• WP2.2.4 The TSEPs must be extrapolated in order to predict the future state of the static component. This one depends on the mission profile. This step will be done offline according to historical data and current measures. Several techniques can be used: 1-step serial predictors (e.g. Kalman type), regressors (Gaussian Process regressor, ....) or extrapolators based on Artificial intelligence such as neural networks, LSTM, neuro-fuzzy, residual analysis ... One of the locks should be to manage sparse or missing data. Another one is to associate a degree of confidence or uncertainty with the outcome found
• WP2.2. 5 Writing the thesis
Deliverables
• Ageing Data for SiC modules accelerating ageing model design
• Regressor model for prognosis;
• Yearly reports;
• Final report in the form of a PhD manuscript.
