Welcome to Multiphysics Simulation and Design of Power Electronics


Simulation of power electronic components and systems is key to achieve the Design for Reliability (DfR) approach. Besides, multi-domain, multi-physics and multi-objective optimization tools are required for future integrated power electronics. This industrial/PhD course will equip attendees with the theory, fundamentals and advanced multiphysics simulation and modeling techniques required to effectively design power electronics systems and components. When selecting a new power electronics component, the design engineer must consider thermal management, EMC/EMI, magnetics, mechanics and manufacturability. Although power electronics designers often concentrate on only one critical issue at a time, e.g. thermal management, in a DfR approach, the trend is to take into account multiphysics aspects.

The course targets applying the problem based-learning (PBL) teaching method and presents a step-by-step training on design development of power electronics converter and components using multiphysics tools including ANSYS Workbench, Simplorer, , Q3D Extractor, Icepak, and Mechanical to design power electronics from component level – e.g. power module, heatsink and fuse– to system level – e.g. circuit parasitics. The course contents are based on the latest research outcomes of the Center of Reliable Power Electronics (CORPE). Following the PBL model that focuses on learning by doing and reflection, the course activities will include group work, problem defining and solving applied to real-world case studies, practical exercises, and discussion sessions.

The course is organized in three consecutive days of full-time activities (08:30-16:30). Attendees armed with the knowledge gained from this course will be able to apply advanced simulation tools to streamline and shorten the design cycle, improve the reliability and deliver high quality products.

The course will cover the following lectures:

Day1: Electrical parasitics and electromagnetics multiphysics simulation and design of power electronics

Day2: Electro-thermal and thermo-mechanical multiphysics simulation and design of power electronics

Day3: Hands-on exercises and discussion

Important information concerning PhD courses We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
