L2EP

What L2EP does

L2EP (Laboratoire d'Electrotechnique et d'Electronique de Puissance de Lille) is a publicly funded French university research laboratory founded in 1989 and affiliated with Université de Lille, headquartered at the Cité Scientifique campus in Villeneuve-d'Ascq. The lab operates across four engineering schools (Université de Lille, Centrale Lille, Junia/HEI, and Arts et Métiers) and is structured into four research teams covering Control (Commande), Power Electronics (Electronique de Puissance), Numerical Tools and Methods (OMN), and Power Systems (Réseaux). It does not produce commercial products; its output consists of fundamental and applied research, PhD and Master's training, and technology transfer through CIFRE industrial PhD contracts and collaborative projects with companies such as Safran and Jeumont Electric.

Its technical scope spans electrical machines, power converters, HVDC networks, smart grids, wide bandgap (SiC/GaN) semiconductors, digital twins of electrical networks, non-destructive testing of electrical machines, and advanced numerical methods for electromagnetic problems (including Cauer Ladder Network reduced-order modeling and parametric model order reduction). Notable research infrastructure includes SAW sensors for multiphysics characterization of ferromagnetic sheets, grid-forming control algorithms for converters, and modular multilevel DC-DC converter architectures for HVDC grids. The lab also houses a sub-structure called LAMEL (Laboratoire Ampère Méthodes et Equations), which celebrated its 20th anniversary in 2026.

Financially, L2EP operates as a non-commercial public research unit. Its activities are funded through the French Ministry of Higher Education, French National Research Agency (ANR) grants, European research programs, CIFRE industrial PhD contracts, and institutional support from its partner schools. Knowledge dissemination occurs through academic publications, conference participation (IEEE PowerTech, Soft Magnetic Materials, Eurohaptics), doctoral seminars, and technology transfer to industrial partners. The lab reported 61 employees and has been continuously active through 2025–2026, with multiple internal and visiting seminars, ongoing thesis defenses, and a recurring awards record (IEEE PES France 2025, IEEE PowerTech 2025 Best Paper, SMM 2025 Best Poster, JCGE 2024 Grand Prix, Eurohaptics 2026 Best Demo, Safran Prix Jeune Chercheur, Galileo Ferraris Contest 3rd prize).
