  • Introduction

    In the field of electrical energy conversion, static converters make it possible, through the use of semiconductor switches and their control, to manage energy exchanges between an electrical energy source (battery, alternator, etc.) and a receiver (organ consuming electrical energy to transform it (movement, light, etc.)). The energy efficiency of these devices is at the heart of the strategies for developing products and services for the energy transition deal. More precisely, in transport applications, the constraints induced lead the research activities carried out in power electronics. Thus, some research focuses on, the design of multilevel static converters, or the use of new materials and processes that make them more efficient or more effective. In the aeronautical field, the most striking constraint is known to be the ratio of the electrical energy converted to the volume and mass. This latter constraint tends towards the development of high- power devices in smaller volumes. The “Laboratoire Génie de Production”, and more particularly the e-ACE2 team, is interested in integration strategies allowing the miniaturization of conversion devices and in particular power modules.

    The proposed research work aims to design - from model to object - a highly integrated power module, inverter leg type, medium power and voltage, multilevel, based on new wide band gap technologies. The idea is that it can be itself an elementary brick of a multilevel conversion architecture.

    Scientific targets

    Show how a transverse approach makes it possible to create an integrated and modular power module, for a multilevel topology apply to aeronautical applications, while simultaneously and significantly improving:

    • Conversion efficiency (at the architecture level): Target 1;

    • Conversion efficiency (at module level): Target 2;

    • The reliability of the architecture (at the architecture level): Target 3;

    • Repairability (for module and architecture levels): Target 4

    • Operation in degraded mode (for module and architecture levels): Target 5.

    Scientific challenges

    The first scientific challenge concerns the development of a design method, associated with a performance evaluation method, which makes it possible to design a module that satisfies the five targets.

    The second scientific challenge is the development of a method for evaluating the reliability of a multilevel architecture.

    The first technological challenge consists in designing and manufacturing a multi-technology module, which can be an elementary brick of a multi-level topology. This design will be based on choices resulting from compromises between proven, innovative or disruptive assembly technologies, relative to the listed targets.

    The second technological challenge concerns the development of a test bench for characterizing the multi-level topology based on the integrated module, and the testing of an equivalent architecture made with component of the shell components.

    Benefits

    Net Salary (this will be confirmed) 1650€per month.

    Selection process

    First step, send a CV and a motivaiton letter. Then, in a second stpe, a face to face (using visio) meeting will be scheduled for some selected applicants between the 4/12 and the 16/12. Decision will be taken around the 20 of december 2022.
