The main goal of Power Electronics is the correct management of the electric power through different electronic devices. The students have to be ready to cope with electronic issues that have been previously studied in common and specific industrial modules within this degree. Students are enforced to have attended all electronic related subjects, being this the main reason to be in the third year of the degree.

Power electronics is one of the most common fields that arise in the everyday life. It is necessary for most of the industrial production equipment feeding and control. It is used for human body implants feeding, energy management of satellites, electric car control, high-speed trains, energy conversion of renewable energy sources,  capacitors control, among others.

1. Description of the operation of power electronics elements employed in electrical power conversion.
2. Design and analysis of power electronic converters for their use in power electronic systems.
3. Demonstrate and analyze the importance of computer simulations in the design of power electronic circuits and analyze its actual limitations.
4. Build and test power electronic converters using laboratory measurement equipment, oscilloscopes, power analyzers, harmonic analyzers and the use of specific bibliography sources.

TEACHING METHODS

1. The lecturer will provide the student with the needed knowledge to assimilate the fundamental theoretical concepts in a natural manner.
2. Individual exercises to be developed will be proposed in each subject to the students to upload them once solved to eGela. This way, an active methodology will be applied which will help to deepen the knowledge of the subject.
3. All the theoretical concepts previously worked on lectures will be tested with simulations made in a software called PSIM in groups. Afterwards all the results report will be uploaded to eGela.
4. In order to acquire skills in the field, different converter set-ups will be developed collectively in the laboratory.
Afterwards the processed measurements and interpretations in a report format of practical works will be uploaded to eGela.
In case of new states of alarm that imply the change to the online teaching modality, Blackboard sessions will be used for lecture and problem classes. The practices will be carried out using simulation software PSIM.
In the event that sanitary conditions prevent the realization of a teaching activity and / or face-to-face evaluation, It will activate a non-face-to-face modality of which the students will be informed promptly.

TYPES OF TEACHING 

Legend: M: Lecture-based S: Seminar GL: Applied laboratory-based groups GO: Applied computer-based groups TA: Workshop TI: Industrial workshop GA: Applied classroom-based groups GCL: Applied clinical-based groups GCA: Applied fieldwork groups 

Evaluation methods:

• Continuous evaluation
• End-of-course evaluation

Evaluation tools and percentages of final mark

• Written test, open questions 60%
• Exercises, cases or problem sets 15%
• Individual assignments 15%
• Teamwork assignments (problem solving, Project design) 10%

ORDINARY EXAMINATION PERIOD: GUIDELINES AND OPTING OUT

The evaluation method for all students will be continuous evaluation, consisting of four items: 1) 60% of the mark associated with the written tests (controls and exam), 2) 15% of the mark associated with attendance and achievement active part of the labs. Attendance to laboratory practices in the schedule proposed by the School it is mandatory. 3) 15% deliverables / directed tasks (problems, jobs of greater complexity) that may include oral defense. The delivery of the works is obligatory on the dates indicated by the professor. 4) 10% Simulations with PSIM software for each of the subjects of the course. The delivery of simulation reports is mandatory in the dates indicated by the teacher.
Halfway of the semester a partial exam will take place, and a second one at the end of the semester. If the students pass any of them, it will not be compulsory for them to do this part in the final exam. The minimum mark to pass the partial exam is set in 5/10. It is mandatory to pass (obtain 50% of the points of each item) independently each of the four previous items to pass the course. If this condition is not met, the course will be failed (final grade = the lowest of the marks corresponding to the 4 items). When each one of them is passed individually, the final grade will be obtained from the average of the sum of the scores obtained in the four indicated items.

If the items of laboratory practices and / or deliverables of solved problems and / or simulation reports are passed the grade obtained in the same (s) will be kept until the extraordinary call.

 
The parts passed in the ordinary call will be saved for the extraordinary call except for the written partial exams that will not be saved (only in the current academic year). In case of NOT ATTENDING the laboratory practices and / or of NOT DELIVERING the proposed work in due time the subject will be FAILED regardless of the grade that the student can obtain in the written exam (final mark = the lowest of the marks corresponding to the 4 items). In the case of continuous assessment, if the weight of the test is greater than 40% of the grade for the subject, it will be enough with not appearing to the final test so that the final grade is not presented.

In the event that a student wishes to take the final assessment, they must present the lecturer, within the period of the first nine weeks of the semester, a signed printed writing indicating the intention to carry out this final exam. This final exam will evaluate all the competences and will consist of:
a) Final written test (70%).
b) Carrying out a laboratory practice in which the learning result of the subject will be evaluated related to the application of experimental techniques (15%).
c) Carrying out a simulation test with PSIM of any of the previously analyzed circuits (15%).

To renounce the call, it will be enough if the student does not assist to the final exam, stating in this case the qualification of it as Not Presented.
In the final test (exam) it is only allowed to use, in addition to writing tools, a scientific calculator. In case of on-line exams, all above mentioned is maintained. In the event that sanitary conditions prevent the realization of a teaching activity and / or face-to-face evaluation, it will activate a non-face-to-face modality and the students will be informed promptly.

EXTRAORDINARY EXAMINATION PERIOD: GUIDELINES AND OPTING OUT

The parts passed in the ordinary call will be saved for the extraordinary call except for the written partial exams that will not be saved (only in the current academic year). In the extraordinary call, the same criteria will be applied as in the final evaluation of the ordinary call. This final test will evaluate all the competences and will consist of:

a) Final written test (70%).

b) Carrying out a laboratory practice in which the learning result of the subject will be evaluated related to the application of experimental techniques (15%).

c) Carrying out a simulation test of any of the study circuits (15%).

To pass the subject, the minimum mark for the final written exam is 5 points.

It is mandatory to pass (obtaining 50% of the points of each item) independently each of the three aforementioned items to pass the course. If this condition is not met, the course will be failed (final grade = the lowest mark corresponding to the 3
items).
When each one of them is passed individually, the final grade will be obtained from the average of the sum of the scores obtained in the four indicated items.
To renounce the call, it will be enough if the student does not assist to the final exam, stating in this case the qualification of it as Not Presented.
In the final test (exam) it is only allowed to use, in addition to writing tools, a scientific calculator. In case of on-line exams, all above mentioned is maintained.
In the event that sanitary conditions prevent t e realization of a teaching activity and / or face-to-face evaluation, it will activate a non-face-to-face modality and the students will be informed promptly.
