Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

The Temary consists of two parts:

Part I: Power Electronics (Topics 1 to 5)

Part II: Electric Drives (Items 6 to 14)

Part I, is 33% of the Final Note of the subject

Part II, supposes 67% of the Final Note of the subject.

Both parts contain:

Performing Theoretical-Practical Exam, written, which represents 70% of the final grade.
Assistance and completion of laboratory-simulation practices, which represent 15% of the final grade.
Realization / exhibition of works, directed academic activities, that suppose 15% of the final qualification.
In the Examination Test with theoretical contents and problems, the CEL1, CT2 and CT4 competences and the learning outcomes 6 and 7 are evaluated.

The CEL1, CT2 and CT4 competences and the learning outcomes 6 and 7 are evaluated in the class assignments and delivery of internship reports.

In the attendance to practical classes, in person or virtual, the competences CEL1, CT2 and CT4 and learning outcomes 6 and 7 are evaluated.

(*) The Centre may establish a different percentage of attendance depending on the number of students and the capacity of the classroom/laboratory in accordance with health measures.

(**) The Centre may establish rotating attendance depending on the number of

students and classroom/laboratory capacity according to health measures (class in the timetable and classroom/laboratory assigned to a part of the group and retransmission by videoconference to the rest, with periodic rotation of students, as determined by the Center

EVALUATION SYSTEM:

It will be similar to the evaluation system for a classroom scenario, indicated in the teacher's guide. If required, and the scenario is mixed, the evaluation will be done by multimodal and mixed means with the indicated resources.

Theoretical-practical examination, written, which represents 70% of the final qualification.
