METHODOLOGY IN A CLASSROOM SETTING:

Theoretical presentations will be made in the classes and problems related to the topics presented will be solved.
Simulation/lab practices of electric drives and power electronics will be carried out.
Technical visits to industrial facilities will be carried out
Work will be carried out in groups of students and will be presented in class.

In all the activities and methodology indicated, the competences will be taken into account:

CB2R That students know how to apply their knowledge to their work or vocation in a professional manner and possess the competencies that are usually demonstrated through the elaboration and defense of arguments and problem solving within their area of study.

CB3R That students have the ability to gather and interpret relevant data (usually within their area of study) to make judgments that include reflection on relevant social, scientific or ethical issues.

CB4R Students are able to convey information, ideas, problems and solutions to both specialized and non-specialized audiences.

CB5R That students have developed those learning skills necessary to undertake further studies with a high degree of autonomy.

CEL1 Knowledge of machine control and electric drives and their applications. Applied knowledge of power electronics.

CT2 Ability to manage information, handling and application of technical specifications and legislation necessary for engineering practice.

CT4 Ability to apply new technologies including information and communication technologies.

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
