Power Electronics aims at the processing of energy as opposed to the processing of information, which is the goal of conventional electronics. To achieve this objective, the following steps will be taken:

- Study the issues associated with the conversion and control of electrical energy.

- Present the specific methods used in the analysis and design of power converters.

- Analyze the switching characteristics of semiconductor devices with high energy levels.

- Analyze and design power converters.

- Show real applications where the techniques studied in the conversion of electrical energy are applied, with special attention to applications in renewable energy or electric mobility.

1.- Understand the issues that create the need to apply power electronics techniques.

2.- Examine the different applications of power electronics and the systems used in each application.

3.- Study the various types of converters used in power electronics.

4.- Understand and know how to apply the specific analysis techniques for each type of converter.

5.- Understand the control techniques for each function in this area and the methods applied, as well as the circuitry and available commercial ICs.

6.- Study the specific electronic components used in the control of electrical energy and their behavior in the context of power circuits.

7.- Learn to choose the most suitable solution among the various solutions provided by power electronics for the control of machines and electrical systems.

8.- Appreciate the importance of power electronics techniques in solving problems and advancing alternative energies.

The index to be followed to achieve the proposed objectives is:

Topic 6: Applications and Solutions in Alternative Energies

Lectures and laboratory sessions.

Lectures will provide the necessary knowledge for the proper development of the learning process. Active student participation in class will be encouraged with specific questions on the topic being discussed. The presentation of power electronics analysis tools will be carried out in parallel and transversally.

Laboratory practice classes will be conducted in small groups and will focus on implementing practices with power converters. The practical sessions will be coordinated with the delivery of theoretical concepts, allowing students to experience the knowledge acquired. In some practical sessions, students will be required to present a preliminary study of the practice.

If access to laboratories is not possible, the practical sessions will be conducted through simulations.

• Continuous Assessment System
• Final Assessment System
• Tools and qualification percentages:
  • Written test to be taken (%): 80
  • Realization of Practical Work (exercises, cases or problems) (%): 20

A written exam will be conducted during the exam period.

The final grade will consist of 80% from the written exam and 20% from the practical sessions.

To calculate the average, it is necessary to obtain more than 4.5 in the written exam and more than 5.0 in the practical sessions.

If a student scores more than five on the written exam but fails or has not completed the practical sessions, it will be possible to take a practical exam by arranging it with the professor.

Failure to attend the written exam will be evaluated as Not Presented, even if the practical sessions have been completed.

The extraordinary examination session will follow the same criteria as the regular session.

- Theory guides
- Practical work statements
- Practical guides

These materials will be available on the eGela page of the course.
