Power Electronics

AD and DC circuits analysis

Basic electronics

Basic knowledge on control systems

The teaching methodology consists of:
Classroom lectures with projection of slides about the covered topics;
Laboratory classes, with illustrative exercises, simulation studies and experimental observation.

The intended learning outcome of this curricular unit is to endow the students with technical knowledge on
energy conversion through power converters, including the understanding of main conversion topologies,
their applications as well as design and control techniques.

Power electronics deals with the process of converting and controlling electrical power.
The syllabus reflects the learning objectives of the unit This knowledge, together with those acquired in
other courses (e.g., electrical machines, control of electromechanical systems and microcontrollers) form
the basis for more advanced topics of the following semesters.
This curricular unit will start by remembering the basics of power semiconductor devices followed by the
rectifier. The discussion of line-current harmonic distortion and input power factor in nonlinear
loads will be an important topic for the students curriculum. Then dc-dc converters and inverters (dc-ac
converters) will be introduced. The importance of inverter operation and its use in micro generation
renewable energy systems will be described. Harmonic control will also be a relevant issue. Students will be able to
have an integrated view of power conversion, particularly from the electronic control point of view.
