Description

The purpose of the Power Electronics subject is to train students so that they are able to understand, interpret and perform calculations in the most basic Power Electronics circuits, in their four conversions (CC/CC, CA/ CC, CC/CA, CA/CA), in addition to distinguishing between the different electronic devices within this discipline. Only the permanent regime will be considered, the transitory regime will not be the subject of study. The most common applications will also be presented.

The classroom (physical or virtual) is a safe space, free of sexist, racist, homophobic, transphobic and discriminatory attitudes, either towards students or towards teachers. We trust that together we can create a safe space where we can make mistakes and learn without having to suffer prejudice from others.

Evaluation system

The final grade (QF) of the subject is calculated as follows:

QF = EX 0,7 + P 0,2 + T 0,1

where EX=0,5 Ex1+0,5 Ex2

Ex1 and Ex2: exams

Q: internships

T: work

Minimum grades:

EX: 3,0

P: 4,0

T: 3,0

The grade of the EX activity must be equal to or higher than 3,0 to be able to average with the other assessment activities. If this minimum score is not achieved, the subject will be suspended.

In case the grade of activity P is lower than the corresponding minimum mark, P = 0.

If the grade for activity T is lower than the corresponding minimum grade, T = 0.

If the subject is not passed in the ordinary assessment, there will be an extraordinary recovery session for activities Ex1 and Ex2. The grade of this recovery will replace that of Ex1 and Ex2 activities within the evaluation of the subject. P and T activities are not recoverable.
