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.
