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
9:00am - 9:30am
Introduction to EMC standard evolution from Aeronautic and Automotive point of view
Vincent MELCHOR1, Frédéric LAFON2, Charles JULLIEN3
1SafranTech, France; 2VALEO, France; 3Safran Electrical & Power, France
The need to reduce greenhouse gas emissions in transportation is a crucial issue for the coming years. The contribution of electric propulsion to both the automotive and aeronautical sectors is undeniable, but it also creates challenges for EMC engineers. Standardizing these systems is essential to ensure user safety. Both fields are advancing in ways that are sometimes similar, sometimes different, and exchanges between the two must be strengthened to share best practices and resources.
9:30am - 10:00am
Main ongoing evolutions in EMC immunity automotive standardization and induced challenges
Rémy PERROT1, Frédéric LAFON2, Xavier BUNLON3
1UTAC, France; 2Valeo, France; 3AMPERE, France
ISO/TC22/SC32/WG2 is the standardization group which deals with EMC automotive immunity standards. Both vehicle and component tests are considered. During the last 3 years, experts of the group focused on updating ESD standards, immunity to onboard transmitters with new calibration method and reverberation chamber. This paper will show main evolutions and explain why they have been developed.
10:00am - 10:30am
Megatrends in Automotive and their impacts on future standardization
Frédéric LAFON1, Rémy PERROT2, Xavier BUNLON3
1Valeo, France; 2UTAC, France; 3AMPERE CARS, France
Electronic architectures and technologies are evolving rapidly in the automotive industry in order to support the transformation related to ADAS and to electrification in particular. The consequences on EMC are then important in terms of frequency band to cover, test methods and connection with other disciplines such as Safety. In this presentation we propose to review these megatrends and discuss how this directly affects the activity ongoing in the international EMC standardization committees (ISO / CISPR).
