The Industrial Electronics Curricular Unit aims to provide training to students with regard to the analysis of the main power semiconductor devices and the operation of basic topologies of power electronics converters. It is intended that at the end of the curricular unit the student will identify the topologies necessary for the DC/DC, DC/AC, AC/DC conversion as well as their correct sequencing in conversion steps. The student should be able to characterize the main signals using the calculation of average and rms values. Notions of non-linear load, harmonic content and impact on power factor will be introduced. It is also intended that the student will be able to relate converter topologies with industrial applications such as drives, integration of renewable energies, lighting, power supply of isolated loads, electric mobility, among others. The student must be able to use simulation tools to analyse the operation of the converters studied and carry out their simplified design, as well as being able to design the respective printed circuit boards with dedicated software tools. The student will be faced with the implementation of some topologies in a laboratory environment.

1. Power semiconductor devices: Diode, thyristor, MOSFET, IGBT; limits and characteristics.

2. Introduction to the concepts of DC/DC, DC/AC, AC/DC conversion in steady state.

3. Characterization of periodic signals in the context of power electronics and notions of non-linear load.

4. Basic conversion topologies and associated problems: AC/DC (single-phase and three-phase rectifiers), DC/DC (buck, boost, buck-boost); DC/AC (single-phase and three-phase inverters).

4. Simulation tools and converter design tools on PCB boards.

5. Power electronics converters in industrial applications.
