Developments

The L2EP laboratory has developed a number of tools that are part of its scientific patrimony and relies on experimental means developed by its teams.

code_Carmel

code_Carmel is a 3D finite element code for studying low frequency electromagnetism problems. This code is now developed with Edf R & D since 2008 as part of a joint laboratory, LAMEL (Numerical Tools and Methods team).

Sophemis

The Sophemis platform is a supervisor of optimization of electrical machines in their environment. It offers many multi-objective, multi-physical and multi-granular methodologies (Numerical Tools and Methods team).

REM and FVG

The Macroscopic Energy Representation (EMR) is a formalism of graphical representation of non-elementary energy systems, based on the principle of interaction, for a systematic deduction of their Control structure (Control team)

The Generalized Vector (GVF) is an extension of the « space vector » approach to n-dimension systems, typically machines and converter systems with more than two independent currents. It allow to decouple the studied system into independent subsystems.

Storage Characterization

The storage characterization bench is used to test and characterize storage components such as supercapacitors and electrochemical cells under real-world constraints (cycling). (ELECTORNIC POWER Team)

EMC technical platform-fast components

Technical platform for the characterisation of magnetic materials

L2EP has a technical platform for characterising the magnetic materials used in manufacturing electric machinery. Its goal is to develop reliable and precise models. There are standard systems (Epstein, Single Sheet Tester, etc.) for the rapid characterisation of magnetic steels. Using equipment developed according to bespoke specifications for non-standard cases, the magnetothermal properties can be characterised and the ageing of the magnetic properties of steels with a low silicon content can be analysed. Moreover, experiments using the magneto-optic Kerr effect have been developed. (Numerical Tools and Methods team)

Technical platform for the study of piezoelectric systems

The laboratory designs and verifies piezoelectric vibrating systems. It achieves this using real-time control and acquisition equipment, a laser vibrometer, linear power supplies and a tribometer to analyse the friction of piezoelectric plates with tactile feedback (Control team).
