Syllabus Information

5.1. Methodological overview

The learning process designed for this subject is based on the following:

• The teaching process will involve three main levels: lectures, laboratory problems and, active student participation.
• In the lectures the theoretical basis of electronic power supplies will be exposed.
• In the classes of problems the students will develop worked-out examples
• The laboratory practices will be developed in small groups where students perform computer simulations and assembly of electronic power supplies.

5.2. Learning tasks

The program offered to the student aims to help him achieving the expected results and includes the following activities ...

CLASS WORK: 2.4 ECTS (60 hours)

1) Theoretical classes (30 hours).

Keynote sessions presentation of theoretical contents. The concepts and fundamentals of electronic power systems, illustrating them with examples will be presented. The student participation is demanded through questions

2) problem solving classes (15 hours).

Problems and cases involving students, coordinated at all times with the theoretical contents will be developed. Students are encouraged to work the problems previously.

3) Laboratory practicum (15 hours).

It will consist both assembly and computer simulation of electronic power supplies. The student will have a script for each practice.

TAKE-HOME WORK: 3.6 ECTS (90 hours)

4)  Student assignements (24 hours).

They are activities that the student will perform alone or in groups and that the teacher will propose throughout the teaching period. In order to assess the progressive acquisition of knowledge, they will be proposed resolution of a sheet of short questions. The developed work is associated with the laboratory practicum.

5) Study (62 hours).

The ongoing work of the student will be encouraged by the homogeneous distribution throughout the semester of the various learning activities.

6) Evaluation tests (4 hours).

In addition to the assessment function, it is also a learning tool with which the student checks the degree of understanding and assimilation reached.
