EP: Power Electronics

General introduction and research projects


Power electronics has become the central interface for the control and conditioning of electrical energy at all power levels. Highlighted by the requirements of compactness of portable systems, this discipline is also strongly influenced by the context of energy savings, sustainable and green electronics. The introduction of non-conventional energy sources and storage, the need for ever-increasing electric mobility, combined with the flexibility and efficiency provided by static power converters have led to a proliferation of applications in industrial fields and consumer.

In this demanding environment where the desired performance are related to energy efficiency, electromagnetic standards and miniaturization, the Power Electronics team focused for the last ten years on upstream research activities. Among others, this research includes the technological and conceptual aspects, to propose new concepts and tools for future conversion systems. Thus, a major effort was made on the power integration, especially the monolithic and hybrid integrations to offer required breakthroughs in our field. This effort continued into the joint / coupled design approach of power semiconductor devices and their environment, breakthroughs in packaging, integrated or optimal cooling systems for power devices, and in the design of generic blocks and towards wide band gap devices. In conjunction with this guidance, the team is actively pursuing the development of modeling tools, while collaborating with the MAGE team in the view to better meeting the changing needs of design. This is of particular interest, especially since packaging and EMC / EMI are challenged by increased switching speeds and physical proximity of the new components.

Along with these upstream activities, the team wants to remain close to applications whose needs are driving innovation. The actions in this direction (CIFRE PhD funding and agreements, collaborative projects) focused on power conversion with a high added value such as uninterruptible power supplies, transportation and contactless energy transfer.

To achieve these objectives, the research is organized around three complementary areas:
 
  • Power semiconductor devices and integration: integrated functions, drivers, packaging and thermal management.
  • Design of power converters and their valorization: Embedded systems in transportation, Uninterruptible Power Supplies...
  • Electromagnetic modeling and design tools for passive components, systems and EMC.

The organization of these areas is to ensure the proficiency of various aspects of a static power converter, from the component to its integration within the thermal and electromagnetic environment. The global system level constraints and control is being conducted in collaboration with the SYREL team at G2Elab. This desire to "coupled design" is more essential than ever introduced by the strong constraints facing our discipline but also by the advent of the wide band gap devices affecting all three research activities. From this perspective then, the team is particularly well positioned in terms of modeling tools (InCa, Flux, Cades, GOT) and technological means (CIME-Nanotech, CEA-LETI).
