| Abstract |
This paper presents experiences and results from a
project task in power electronics for students at Chalmers
University of Technology, Göteborg, Sweden, based on a fly-
back test board. The board is used in the course Power Elec-
tronics 2. In the project task, the students design snubber
circuits, improve the control of the output voltage, improve
the gate drive of the main MOSFET transistor and study
the influence of stray inductance. The student project is di-
vided into smaller steps. The project goals are given but the
procedure of how to define and to obtain the results is not
specified. Instead the students have to make their own spec-
ification in order to reach the goals. "Tools" that are given
to the students are the hardware, measurement equipment,
an example of the circuit in the circuit simulation software
PSpice, and in addition lectures covering the items needed
in order to obtain the project goals. The project formula-
tion is build on the ideas from the CDIO-initiative, where
the students are encouraged to think in a complete process
structure.
The results found was a substantial engagement by the
students, with both positive and negative reactions from
the students. The negative reactions were mainly that the
project specification was too vague, i.e. when the students
encountered the (C=Conceive)-phase of the CDIO struc-
ture. |
