Packaging & Multiphysics

Packaging and Multiphysics focuses on the increasing integration of PE modules and systems, high fidelity characterization and modelling of power electronic components as well as on optimized and very compact integrated power converter systems with integrated enhanced functionalities (e.g., prognosis, diagnosis, advanced measurements, parameter estimation and gate driving, and state-of-health monitoring). Integration of enhanced functionalities and "intelligence", empowered by machine learning approaches, is a new development direction towards the digitalization of PE systems.

Research Foci

  • High-fidelity multi-physics component modeling through experimental characterization and measurements allows the optimization of the system towards high-power density and integration of enhanced functionalities.
  • Accurate multi-physics modelling of components and subsystems which are not available from manufacturers and are normally not completely considered in the design of PE systems, e.g., related to high-frequency model and parasitics, packaging details, thermal behavior, material properties, etc..
  • A more accurate design and simulation of PE components and systems allows optimization of the functional, mechanical and thermal performance of the power converter towards 3D integration and high-power density.
  • Dependable Power Electronics: The inclusion of above mentioned detailed component models through “intelligence” and enhanced functionalities aims at more dependable PE systems.

Research competencies

  • Design and optimization of system-level integrated power electronics, modules and systems with enhanced functionalities going beyond state-of-the-art by e.g., multi-domain design and multi-physics simulations, 3D system integration, advanced cooling solutions, active and passive component embedding, advanced gate driving and diagnostic functions.

Applications

  • Tiny Power Box 1 & 2: In the “Tiny Power Box” projects, the focus is on optimizing the power density of built-in chargers in electric cars, so-called onboard chargers. The aim is to reduce weight, save components and space while at the same time increase power density, achieve highest efficiency for charging and the vehicle-to-grid case, as well as increase environmental compatibility.
