Ph.D course in Electromagnetic design (7.5 ECTS) spring 2012
Goal: To theoretically using “simple formulas” design a magnetic component as well as to implement
the model in Maxwell/Simplorer or Comsol Multiphysics. Moreover, to compare the results obtained
and discuss differences. Implement a converter in Simplorer and couple it to the Maxwell FEM model
and compare the difference between an ideal voltage/current supply with a non ideal voltage supply.
Examination: A project report comprising at least: Presentation of the designed object, theoretical
analysis using simple formulas determining the main quantities such as losses and flux levels, etc, the
same quantities obtained using Maxwell/Simplorer. The object to be investigated can be an inductor,
a transformer, an electric machine or some other type of Electromagnetic/Electro-Thermal object.
The final model should also include a circuit model in Simplorer, coupled with Maxwell. Finally a
presentation at a closing seminar is a part of the examination.
