Also valid for First cycle degree programme (L) in Electronics Engineering for Energy and Information (cod. 8767)
Learning outcomes
After completing this course, the student 1) recognises the electronic components and the main functional blocks of a power converter system for the energy conversion; 2) is able to properly analyse any electronic converters - rectifiers, linear regulators, amplifiers, inverters and switching regulators-; 3) knows the different design solutions for any kind of application -DC power supplies of different power, DC and AC electric motor driver circuits (mainly in industry), amplification of signals (primarily in ICT)-; 4) is able to design and to tune for several trade-offs most of the energy conversion circuits. This knowledge can be used for the design of power supplies, of energy management systems and of electronic drivers for power transducers in many industrial applications.
Course contents
Power electronic circuit principles of analysis (in the time domain and frequency domain). Definition of efficiency, power factor and distortion in amplifiers and electronic power converters.
Main power electronic devices and technologies.
Single and three phase rectifier circuits. Voltage regulators. Filters for distortion mitigation.
Power amplifiers: main classes of operation.
Issues on electric motor control.
Electronic switches (devices and technologies). Electronic power converters operating in switching mode. Switching networks. Switching laws (2 or 3 levels). Diodes, bipolar transistors power MOSFETs and IGBTs. PWM control issues. Two and four quadrants loads.
DC/DC converters (choppers): buck, boost, buck-boost, Cuk, Sepic and Luo converters. Isolated converters: forward, flyback, full-bridge. Equivalent model of low-frequency switching converters: control methods.
DC/AC (inverters): half bridge or full bridge; multilevel inverters; resonant inverters.
Thyristors: terms of use. AC/DC converters and AC/AC controlled converters.
Hints related to power dissipation and thermal limits in power electronic devices.

Teaching methods
Classroom lessons and exercises performed with chalk and blackboard, preferably without use of projected slides in order to stimulate the student involvement as much as possible.
Assessment methods
The final test is an oral examination consisting of one design exercise and some theoretical and conceptual questions, to play without the aid of nothing more than pen and paper.
The understanding and the mastery of the subjects is evaluated.
Teaching tools
Drafts delivered during the lectures.
Design exercises.
