Session Abstract
This workshop introduce the issues at the level of standards and norms introduced by new technologies within Aeronautical and Automotive transport, in particular with the introduction of electric and hybrid propulsion systems. Indeed, standards must be able to ensure the safety of users by proposing EMC tests that allow the use of future transport in the best possible conditions. For example, with the arrival of the electrification of propulsion in aeronautics and the generalization of power chains, new challenges appear on the control of crosstalk, conducted emissions generated by increasingly high switching frequencies or radiated fields with regard to exposure to waves of the human body. However, on this last subject, the automotive sector has long worked on a normative framework to ensure the safety of people when using electric or hybrid cars. Another example is the arrival of autonomous cars that no longer require human intervention for driving. The automotive regulatory framework will also have to take into account more stringent constraints to ensure passenger safety during journeys, potentially leading it towards constraints close to the aeronautical field. Through these two examples, we can easily understand that the two fields can evolve together and in a coordinated manner to benefit from the work of each. At the end of this workshop, a slot will be dedicated to an exchange on the subject with the audience.
The workshop is divided into topics as: Standard, Nom, EMI, Susceptibility, Emissivity, Crosstalk, Human exposure, Shielding Effectiveness Measurands.
The workshop will help the audience to properly test and design systems and their equipment for product EMC.
Targeted Audience:
• Primary: EMC test engineers in electric and electronic product industries
• Secondary: Power Electronics designers, Systems designers, Harness designers; EMC researchers.
Presentations
11:00am - 11:30am
Challenges of designing HIRF & LIE robust equipment within the new mobility context
Thomas EUDES, Frédéric LAGO, Stéphane BLANC
Safran Electronics & Defense, France
An overview of the problematic management of Lightening and HIRF for equipment will be provided, incorporating a projection that considers the new constraints related to the energy efficiency of new mobility solutions. Additionally, a focus on the methods & standards for measuring the EM shielding effectiveness of materials will be discussed.
11:30am - 12:00pm
Challenges in the qualification of HV aeronautical systems
Charles JULLIEN1, Jérôme GENOULAZ1, Coralie CHATARD1, Vincent MELCHOR2
1Safran Electrical & Power, France; 2SafranTech, France
The electrification of propulsion in aeronautics presents new challenges in terms of standardization and certification. Indeed, with the increase in on-board power due to the increase in voltage and frequency spectra that are increasingly rich in harmonics, EMC and these protections must meet these new constraints, and standardized tests must also adapt to them.
12:00pm - 12:30pm
Round table on the topic with the audience
Charles JULLIEN1, Vincent MELCHOR2, Frédéric LAFON3, Thomas EUDES4, Rémy PERROT5, Xavier BUNLON6
The objective of this roundtable is to build on the presentations made before opening the debate with the audience on the major themes that will emerge. The presenters will be able to support and expand on their ideas, while the audience will in turn be able to react and together provide answers to the questions raised.
