Electrical Energy Conversion
– project course
The course offers project topics with strong industrial relevance that can include
electrical machines power electronics and control of power conversion systems.
No place limitations
Juliette Soulard, course examiner
Course objectives
Aim: design of an electrical energy conversion application from any given set
of specifications.
After the course, the student should be able to :
* explain all the tasks in a design procedure of a system for electrical
energy conversion
* apply parts of the procedure to design a system for a specific application
* describe the concepts of different modelling tools and apply adequate tools
to predict performance of the designed system
* analyze obtained results using knowledge about the various
approximations the simulation models are based on
* report and present orally the results of the project
* do a critical evaluation of the documentation produced by other students
*project management goals
