CE22: Understand the applications of power electronics.
CE24: Train to design analog, digital and power electronic systems.
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 ordinary final grade (QFO) of the subject is calculated as follows:
QFO = Ex1 0,35 + Ex2 0,35 + P 0,2 + T 0,1
Minimum grades:
Written tests (Ex1 and Ex2): 3,0
Practicals (P): 5,0
Work (T): 5,0
In the event that any of the grades for Ex1, Ex2, P or T activities is below the corresponding minimum mark, the ordinary final grade (QFO) of the subject will be limited to 5,0.
All activities are compulsory. In the event that any of the activities are not carried out, the ordinary final grade (QFO) of the subject will be NP.
In case of not passing the subject in the ordinary assessment, there will be an extraordinary recovery session for Ex1 and Ex2 activities, in the form of an examination (ExR) of all the contents of the subject. The grade of this recovery (ExR) will replace that of Ex1 and Ex2 activities within the subject assessment, as indicated in the formula below, provided it is higher. P and T activities are not recoverable.
The extraordinary final grade (QFE) of the subject is calculated as follows:
QFE = ExR 0,7 + P 0,2 + T 0,1
Minimum grades:
ExR: 3,0
P: 5,0
T: 5,0
In the event that any of the grades in the ExR, P or T activities is below the corresponding minimum mark, the extraordinary final grade (QFE) of the subject will be limited to 5,0.
