Academic management

Electronics is present in a multitude of industrial applications: control and monitoring of processes, communications, energy conversions, lighting, home automation, medicine, etc. That is why it is necessary for any graduate in Industrial Technologies to have solid knowledge in Digital Electronics and Power Electronics.

This subject is part of the group of subjects Electricity, Electronics and Automation of the Specific Technology module, and is taken in the 4th year of the Industrial Technology Degree during the first semester.

The main objective of the subject is for the student to acquire the competences that are set out in Section 3 of this teaching guide. This subject aims to provide the student with specialized training in the field of Digital and Power Electronics so that they can join any field of work within Industrial Engineering with an electronic profile.

On the other hand, the achievement of these skills and knowledge is necessary for the execution of Bachelor's Theses in the field of Electronics, and for a possible incorporation into any of the Master's degrees taught by the University of Oviedo in which electronics is part of the technological content.

Previous knowledge in mathematics, programming, electrical circuits, analog electronics and basic digital electronics is recommended.

Students are highly discouraged to take this subject without previously having passed the subjects "Electrical Technology" and "Electronic Technology" of the degree curriculum.

Unit 2: Power Electronics, applications

This block provides an overview of the utility of power electronics and describes the applications that incorporate power electronic systems. The different blocks of an electronic converter (control, isolation, power circuit) as well as the most common semiconductors are presented. The magnitudes of interest in power circuits are described and the analysis methodology in a power stage is presented with special emphasis on circuit simulation tools due to the exceptional help they provide to the design.
     - Introduction to Power Electronics
     - Power topologies for energy conversion: AC / DC
     - Power topologies for energy conversion: DC / DC
     - Power topologies for energy conversion: DC / AC
     - Power topologies for energy conversion: AC / AC

Laboratory Sessions

P1- Simulation of a controlled rectifier with LTspice
P2- Simulation and experimental test of a boost converter
P3- Simulation and experimental test of an inverter
P4- Introduction to MPLAB and PROTEUS software
P5 - Generation of visual effects with LEDs connected to a microcontroller port
P6 - On the use of a A/D converter
P7 - Speed control of a DC motor with PWM

The estimated duration of each laboratory session is 2h.

The student's face-to-face work is organized into the following categories:

Lectures. Classes where the conceptual aspects of the subject are exposed. The problem of the analysis and design of electronic systems is presented, as well as the process to be followed, considerations to take into account and design guidelines.

Classroom Practice. Procedures and techniques to solve practical problems are explained, as well as the use of tools and equipment available to carry out an electronic design.

Laboratory Sessions. Students will make use of the design software and hardware tools and the laboratory equipment necessary for the implementation, development and experimental application of theoretical concepts. Hands-on learning resources are available in the lab. Lab sessions begin with a description of the task to carry out, which is previously provided through the Virtual Campus so that, when entering the lab, the students do already know what they need to use (documentation, equipment, components, etc.), what previous concepts they must handle and what they are expected to do during the session.

Group Tutorials. The teacher will convene the group to share and monitor the work that has been proposed in the laboratory practices. It is about opening a debate in which each student presents their ideas and the alternatives that they consider as possible solutions. It is intended to develop a critical spirit and detect advantages and disadvantages before making a decision.

Evaluation Sessions. In addition to theoretical exams, students will be required to submit reports and documentation corresponding to the tasks assigned and they will have to answer the questions they might be asked in this regard.

The number of hours required or estimated per topic is established below:

In the JANUARY ORDINARY CALL, the subject will be evaluated based on the following criteria, with the weight indicated below:

Theoretical / practical exam (80%). Written exercise in which students will be asked to answer questions and practical exercises about the different concepts and techniques learned throughout the course.
A midterm exam will be held which, if passed with a grade equal to or greater than 5, will be released from the corresponding final exam of the ordinary call in January. In this case, the mark of the midterm exam will average with the mark obtained in the final exam for the second part of the course.
In the event that the midterm exam is not passed, the student will have to take the final exam entirely.
In any of the cases, a minimum of 5 points out of 10 in the total final mark of the theoretical / practical exam is required to pass the subject.

Exercises and reports (15%). The goal is to measure the degree of knowledge achieved in specific aspects, mainly practical, developed during the current course (not in previous courses). The main tool will be the evaluation of specific objectives associated to the different lab sessions carried out throughout the course. The evaluation will be made on an individual basis. Attending all laboratory sessions is mandatory.

Active participation (5%). The degree of participation of the student in the lectures and in the classroom and laboratory practices will be measured. The completion and presentation of additional work in classroom practices will also be taken into account.

In the EXTRAORDINARY CALLS, the evaluation criteria for each activity will be the same.
There will be a single theoretical / practical exam, in which it will be necessary to obtain a minimum of 5 out of 10 in order to be weighted with the rest of the assessable elements of the subject. A grade lower than 5 in the theoretical / practical exam will result in failing the subject; in that case, the grade obtained will be the minimum between 4 and the value obtained in the weighted qualification of the 3 assessable elements mentioned above.
The mark corresponding to the other two evaluation elements ("Exercises and reports" and "Active participation") will be that obtained throughout the teaching period of the subject and in the current academic year (never in previous courses).

DIFFERENTIATED ASSESSMENT. Once the EPIG Teaching Committee admits Differentiated Assessment for a student, the evaluation activities for that student are as follows:
     - Written theoretical-practical exam (80%)
     - Laboratory exam (20%)

Exceptionally, if the sanitary conditions require so, non-presential evaluation methods may be included. In that case, students will be informed of the changes made.
