Description of the job

A CIFRE thesis offer 'Study of new power supply topologies (M/F)' has just been launched at Airbus Commercial Aircraft in Toulouse.

You will join a team in the 'Electronic Products' department specially dedicated to the design of critical electronic boards and equipment. In more detail, you will be responsible for preparing the future power supply functions for this equipment. This research concerns all Airbus aircraft programs.

The framework for this thesis will meet the following objectives:

·  The study and implementation of new semiconductor technologies;

·  The study and implementation of new topologies and control laws;

·  The contribution of these new features in the development of reusable functions.

In addition, the thesis will be carried out in close collaboration with the AMPERE laboratory of the CNRS and the University of Lyon. The doctoral student will share his time between these two entities.

This 3-year thesis will start in December 2018 (date subject to flexibility).

Tasks & accountabilities

The organization of this thesis work will be done as follows:
Task 1: State of the art and definition of the context
This task consists for the candidate to take charge of the subject. Attention will be focused on the following points:

·  The precise definition of the need

·  The evolution of technologies

·  Numerical control

Task 2: Choice of conversion topologies
This task is focused on the power part of the switch mode power supply. Based on the state of the art, it will be a question here of choosing the power component technologies best suited to the specifications.
This task will be carried out through electrical simulation studies to take into account the characteristics of the new components (high frequency operation). In addition to electrical simulations, it is possible that the candidate may have to deride topologies by using models.

Task 3: Definition of control laws
Once the topology has been defined, this task will focus on studying the various possible control laws for making the converter. This includes taking into account the rapid control of semiconductors, but also preparing the implementation of these control laws on a digital component (FPGA or processors or integrated circuit).

Task 4: Prototyping and Experiments
This task consists of defining and developing a prototype for real-world testing of the topology selected in Task 2 and the control laws defined in Task 3.

Task 5: Writing Study Reports
The task consists of writing a report on each of the tasks described and a final report covering the whole subject.

This job requires an awareness of any potential compliance risks and a commitment to act with integrity, as the foundation for the Company’s success, reputation and sustainable growth.
