(Hybrid electric systems, Electric Actuators, Fuel cell systems)


Team leader

Daniel HISSEL

Context

Our SHARPAC team counts approximately fifty members—teachers and/or researchers, engineers and PhD students.
The team pursues and develops its research in the fields of electric vehicles and renewable energy. It is particularly involved in the CNRS research federation (FCLAB) devoted to hydrogen energy and fuel cell systems.

Goals and Research Areas

The SHARPAC team works in 6 different areas of scientific research:

› Static converters: The aim here is to develop “intelligent” static converters, essentially of the DC-DC type, for low-tension high-current applications, with augmented functionalities and for improved performances, static or dynamic;

› Fuel cell systems: investigations into design, increased durability, and optimization of integrations of fuel cell systems into transport or stationary applications;

› PHIL – power hardware in the loop: the team’s objective in this area is to propose a versatile platform to emulate electrochemical components: electrical energy storage elements, electric alternators and motors, a hydrogen vector allowing validation of close control laws, and algorithms for supervision of energy flows within such hybrid systems;

› Energy management control: this focus area includes both the close control of electric systems and the definition and evaluation of strategies for the supervision of (multiphysics) energy flows within electric hybrid systems;

› Electric actuators: research into modeling, optimization and design of linear/rotary polyphase electric actuators for high-speed applications with high torque density and a high ratio of torque. The targeted applications are transportation (automobile, aeronautical, rail), electrical energy storage (flywheels) or electrical energy production (wind power, cogeneration, turbocompressors for fuel cells).

Microgrids: these small-scale power systems include energy sources, storage and loads. Research focuses on the sizing and energy management of grid components, with a focus on renewable energy integration and hydrogen storage. Strategies consider not only technical criteria, but also economic, environmental and sociologic factors.
