Description

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 the design of a 10 kW voltage-source converter by 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, Maxwell, Q3D Extractor, Icepak, Mechanical, and DesignXplorer to design power electronics from component level – e.g. power module, heatsink and fuse– to system level – e.g. circuit parasitics. It is expected that some lectures to be given by ANSYS simulation experts. 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: Circuit level multiphysics simulation and design of power electronics
Day2: Component to System levels multiphysics simulation and design of power electronics
Day3: Hands-on exercises and discussion
