This course provides the basic knowledge on the static energy conversion for industrial and smart grids applications. Moreover, it aims to provide the knowledge necessary for the high efficiency power electronic converters design also taking into account the electromagnetic compatibility compliance.
With reference to the Dublin descriptors the learning objectives expected are as follows:
•Knowledge and understanding
Depth knowledge and understanding of the theoretical and applied aspects of static power converters and electromagnetic compatibility compatibility
•Applying knowledge and understanding
Ability to analyze and design different power converter circuits for industrial and smart grid applications by also taking into account the aspects of electromagnetic compatibility.
Ability to properly evaluate the performance of power electronic converters in function of the application, the used control technique and the electromagnetic constrains.
Ability to discuss with specialists interlocutors, both on issues related the device and the possible solutions to be undertaken.
Ability to continuous learning, through the correct interpretation of the data sheet provided by manufacturers and the technical bibliography.
For the successful achievement of objectives is required knowledge of Electrical Machines and Power Electronics.

The course is given in Italian
Verification of learning
The Assessment methods includes:
a) practical test with a final report on the laboratory activities.
b) An oral examination about all the topics covered during which we will evaluate all the specified learning objectives.
The pass both tests shall be sufficient. The final exam grade is determined as follows:
1) 20% from the evaluation of the practical test.
2) 80% from the evaluation of the oral test.
The rating is 18/30 granted when knowledge / skills of matter are at least elementary, the 30/30 rating with possible praise, because knowledge is excellent.
