Learning objectives

1. Knowledge and understanding

- The student will address the design problems in the field of power electronics, both from the point of view of semiconductor power devices and power systems. To this end also complements about driver circuits for power transistors and dimensioning of passive components will be provided.

- The student will also obtain knowledge in thermo-mechanical and electromagnetic compatibility aspects, which are of primary importance today.

2. Applying knowledge and understanding

- The student will obtain both hardware and software laboratory skills, engaging in the design of power converters for renewable sources.

3. Soft skill

- The student, through the teamwork, will acquire skill on critical discussion, cooperation aimed at project, and project planning


Skills in circuits for the static energy conversion.

Course unit content

- The first section of the course deals with the thermal aspects and reliability issues in power electronic devices and modules. This part is also preliminary for the laboratory activity, which will be introduced soon and will continue, in parallel with lectures, until the end of the course. This activity will focus on the electro-thermo-magnetic and/or thermo-mechanical simulation of power devices and circuits and on the design of conversion systems from renewable energy sources.

- In the second part the main active power electronic devices will be presented with physical and technological detail, and, subsequently, the driver and snubber circuits which are necessary for their use will be addressed.

- The following section is devoted to the selection and sizing of passive power components.

- The final section of the course presents the main design aspects of electromagnetic compatibility at the system level.

Teaching methods

- Lectures with projection of slides (PDF file provided to students in advance)

- CAD laboratory on:

1) Thermal and electromagnetic analysis of power devices and circuits

2) Design of power conversion systems from renewable energies
The activity in laboratory will include an introduction to the use of the software, guided by the teacher with the help of assistants, and a second part in which a project to carry out will be assignet to work groups of 2-3 students.

Assessment methods and criteria

There will be no tests during the course.
The examination will be composed by an oral session (personal), in which the student must demonstrate that he have understood and learned the content of the lectures given in the classroom, and a written (team) report on the laboratory activity.
The laboratory activity, after some introductory lessons, will consist in carrying out a project assigned to groups of 2-3 students.
The report on the laboratory activity can be delivered and discussed on a different date (after agreement with the teacher) from that of the oral examination.
The score of the oral examination and the score obtained by the report on the laboratory activity will contribute with the same weight to the formation of the final score.
