D60193 - CIRCUITS AND ELECTRONIC SYSTEMS FOR STATIC ELECTRICAL ENERGY CONVERSION

The exam consists of a written test and an oral test. The latter can be accessed even in the case of failure of the written test, both to ascertain the reasons for failure and to verify whether the student is in any case in a position to pass the overall exam.

The written exam will focus on three topics, chosen at random and personalized for each student, among the following:

1. Applications of power electronics, definitions, meaning and calculation of the most used performance parameters for the characterization of the performances of power electronic circuits (10 pt);

2. Power diodes and diode circuits (from the half-wave rectifier to the six-phase rectifier) ​​(10 pt);

3. The thyristor and thyristor circuits (from the semi-controlled single-phase rectifier to the three-phase dual-converter) (10 pt);

4. Fully controllable electronic devices (GT0, BJT and MOSFET) and related circuits (from single-phase rectifiers to single-phase and three-phase inverters with impressed voltage controlled by PWM technique) (10 pt);

5. Operating principle, constitution and sizing of direct-to-direct converters (the buck converter, the boost converter and the buck-boost converter) (10 pt).

The written test consists of open questions; the critical skills achieved by the student in framing the topics covered in the course and the methodological rigor of the solutions proposed in response to the questions formulated are assessed. This test has a maximum duration of two hours and the student cannot use books or manuals. The oral test consists of a discussion of the written test and an interview on the topics of the course program; it assesses the student's ability to communicate the acquired notions through an adequate scientific language, as well as the ability to expose the theoretical contents that are the basis of the various types of exercises present in the written test.

The final grade will be awarded according to the following evaluation criteria:

30 - 30 cum laude: complete, in-depth and critical knowledge of the topics, excellent command of language, complete and original interpretative ability, full ability to independently apply knowledge to solve the proposed problems;

26 - 29: complete and in-depth knowledge of the topics, full command of language, complete and effective interpretative ability, able to independently apply knowledge to solve the proposed problems;

24 - 25: knowledge of the topics with a good level of learning, good command of language, correct and confident interpretative ability, ability to correctly apply most of the knowledge to solve the proposed problems;

21 - 23: adequate knowledge of the topics, but lack of mastery of the same, satisfactory command of language, correct interpretative ability, limited ability to independently apply knowledge to solve the proposed problems;

18 - 20: basic knowledge of the main topics, basic knowledge of technical language, sufficient interpretative ability, ability to apply the basic knowledge acquired;

Insufficient: does not possess an acceptable knowledge of the topics covered during the course.
