Knowledge on Physics, Electrical Engineering and Electrical Systems
Learning outcomes
Knowledge of:
- Basic issues related to static conversion of electrical energy for the most common types of converters taking into account non-ideality of the components and systems / networks to which conversion systems are connected;
- Impact of the converters on the power grid;
- Switching techniques more widespread and corresponding privileges, limitations and contraindications;
- The kinds of resonant converters with specific reference to the stresses on the components;
- Configurations of switching power supplies;
- Apparatus for converting static electricity and its applications in the civil, industrial and power grids with reference to issues related to the various types of disorder;
- Applications for the exploitation of renewable energy sources and distributed generation.

Methods and Criteria for Learning Assessment
The student must demonstrate knowledge of the circuit configurations of the main power electronics conversion systems and must know how to perform the sizing in all of its components in order to have certain output performance.
During the course the student, individually or in a team, must develop under the supervision of the teacher a project of sizing and realization in the laboratory of a type converter.

The final exam tends to evaluate:
a) knowledge and understanding of all course topics;
b) the ability to communicate, in a clear and concise manner, the work done and the results obtained, with rigor and ownership of language;
c) competence in the critical analysis of design choices and results in general.

The assessment is based on a written test with which the student must demonstrate to know how to size a static conversion system of power electronics based on specific performance requirements.
The oral exam, usually lasting one hour, consists in illustrating the project and laboratory activities carried out more in answering some theoretical questions that concern all the topics of the course.

The requirement expressed in point a) is a necessary condition for passing the test.
Candidates will be awarded in the range of excellence (27-30) to those who showed brilliance in all three aspects of quality and, above all, denotes readiness also in identifying approaches to problems similar to those already dealt with.
On the other hand, students who are less effective compared to points b) and c) will be classified in an intermediate band (18-26).
