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.

LABORATORY SESSIONS

1st Practical: Basic analysis of the parameters of the three waveforms in power electronics using different types of loads.

2nd Practical: Single-phase bridge-connected rectifier with LC filter. PF power factor and THD parameters analysis.

3rd Practical: Analysis of voltage, current and power waveform parameters with PSIM simulator in the time world and in the frequency world.

4th Practical: Test with three-phase rectifier connected in bridge and totally controlled, simulating at the same time the same converter with the PSIM simulator.

5th Practical: Test with isolated and non-isolated DC/DC converters, simulating at the same time the same converters with the PSIM simulator.

6th Practical: Single-phase and three-phase inverter with square modulation and PWM DC/AC modulation, simultaneous simulation of the same converter with the PSIM simulator.

7th Practical: Torque and speed control in induction motors using ABB or Danfoss industrial frequency controllers.

This subject is based on the planning of the students' face-to-face and non-face-to-face work.



A methodology based on face-to-face activities will be used:



1. Theory classes: in the Master classes the professor will present the basic theoretical concepts.



2. Exercise classes: The teacher will solve the exercises related to the theory and, in turn, other exercises will be proposed to the students.



3. Laboratory practice: In each subject, converter circuits related to the theory and the exercises will be assembled in the laboratory. In each practical session there will be a small test to evaluate the concepts worked. The attendance to practical sessions will be compulsory.



4. The converters studied in theory will be worked in practice sessions with the PSIM software or at home.



5. In the non face-to-face activities the students carry out individual and group work, but always without teachers, e.g. PSIM simulations and various systematized works and studies.



If the classes cannot be conducted face-to-face, they will be carried out using virtual tools.

• Final Assessment System
• Tools and qualification percentages:
  • Written test to be taken (%): 75
  • Realization of Practical Work (exercises, cases or problems) (%): 25

FINAL EVALUATION SYSTEM



INSTRUMENTS AND GRADING PERCENTAGES



The evaluation method will be the final evaluation. In order to analyze if the students have reached the competences, the following tests will be developed:



- Written test of the subjects taught both in the lectures and in the class exercises, with a final grade of 75%.



- Those who have taken and passed the Laboratory Practices and the PSIM Simulations do not have to take the Practical Exam. The rest must pass a Practical Assembly and Simulation Exam with the PSIM simulator in which the knowledge on the applications of the experimental techniques of the subject will be assessed, with a final grade of 25%.



These two tests must be passed in order to pass the whole course. Consequently, it is necessary to obtain at least the following results simultaneously:



- 50% of the score assigned to the final written test.



- 50% of the score assigned to the practical test.



If any of the parts is not passed, the maximum grade obtained will be 4 and, therefore, it will not be possible to pass the course under these conditions.



If any part is passed in the ordinary exam, the grade for that part will be maintained until the extraordinary exam.



In case of taking the written test, the subject call will be used up.



In order to waive the subject call, in any call, it will be enough not to take the final written test, and the grade will be that of “not presented”.



In the final exam (written exam), in addition to the writing instruments, a scientific calculator can be used.



In the case of online exams, all of the above will be maintained.



In the event that health condition prevents face-to-face teaching and/or evaluation, the online activity will be used and the students will be informed of this modification.

FINAL EVALUATION SYSTEM



INSTRUMENTS AND GRADING PERCENTAGES



The parts passed in the ordinary exam will be reserved for the extraordinary exam.



In this extraordinary final evaluation test all the knowledge and competences corresponding to the subject will be evaluated and it will be divided into two sections:



- Written test of the subjects taught both in the master classes and in the class exercises, with a final grade of 75%.



- Those who have taken and passed the Laboratory Practices and the PSIM Simulations do not have to take the Practical Exam. The rest must pass a Practical Assembly and Simulation Exam with the PSIM simulator in which the knowledge on the applications of the experimental techniques of the subject will be assessed, with a final grade of 25%.



These two tests must be passed in order to pass the whole course. Consequently, it is necessary to obtain at least the following results simultaneously:



- 50% of the score assigned to the final written test.



- 50% of the score assigned to the practical test.



If any of the parts is not passed, the maximum grade obtained will be 4 and, therefore, it will not be possible to pass the course under these conditions.
