The course covers the main equipments used for controlled static conversion of electrical energy and their
most important applications. Of each power converter the operating characteristics and the design criteria are examined.

For the Electrical and Automation Engineering students the goals are:
Knowledge and ability to understand:
1) operation principle and electromagnetic behavior of the main power converters;
2) design criteria of the main power converters on the basis of the application.
- Ability to apply knowledge in order to define the operating conditions and the electrical parameters of the main power converters;
- Ability to apply knowledge in order to choose the power converters for the different applications on the basis of the electrical requirements.

For Energy Engineering students the goals are:
CA1: Ability of analysis and modeling of mechanical/electrical/propulsive components and systems: basic problems and models for industrial engineering, with special reference to mechanical and energy engineering.
CA8: Ability of analyzing plants, components and process technologies and methods of engineering and their economic implications
CC1: In-depth knowledge in the field of energy and electricity
CC9: Generation of cold, electrical systems and electrical machines.

Calculus. Geometry. Electrotechnics.

Lectures supported by projector, power converters modeling through PC use, personalized feedback and coaching to improve every aspect of the student's work.

A successful student should know, understand and evaluate the operation and the design criteria of the main
power electronic converters.

Intermediate tests just for students attending the course;
Oral exam based on theoretical questions oriented to assess:
- knowledge of the power converters operation and of their electromagnetic behavior;
- ability to apply knowledge in order to derive mathematical models and current and voltage waveforms of the power converters;
- ability to apply knowledge in order to define the operation characteristics and the electrical parameters of the power converters;
- ability to apply knowledge in order to choose the power converters topologies for the different applications on the basis of the electrical requirements.
