The students will be encouraged to attend the lectures in an attentive and pro-active and way, aiming to understand the topics while they are explained and eventually taking the opportunity to inquire the lecturer on the spot in case any aspect results not sufficiently clear.
A logical systematic approach and a positively critical attitude will be encouraged, as they represent fundamental characteristics for a good Engineer.

The Power Electronics module provides the basis for attending the further optional module "Laboratorio di Convertitori, Macchine e Azionamenti Elettrici" (~ Power Converters, Electric Machines and Drives Lab) when a power electronics or drives specialization will be chosen by the student.
It will also provide an optional additional background permitting to better understand the aspects related to power converters included among the topics addressed by the module "Meccatronica".

The main classification of power interface circuits is introduced, outlining the general features of power converters in contrast to dissipative amplifiers and highlighting the benefits of switching vs. linear operation. The implementation of switching cells is then addressed, providing a short overview of the main characteristics of available power semiconductor devices and discussing the potential and issues related to series and parallel connections.
The general structure of port-structured direct converters is then analyzed, highlighting the constraints in their operation introducing available and permitted states. The relationships between port quantities are then deduced introducing the switching functions.
The concept of modulation as spectral approximation is presented, highlighting the difference and potential benefits with respect to time-domain approximation. The classification of global, local and hybrid methods is then presented, envisioning the transition towards non-periodic control.
The effects of main structural properties are then analysed, highlighting the relationship with spectral properties and presenting the structural harmonic families elimination methods.
The classical harmonic elimination and constrained optimization methods are presented, discussing their characteristics.
The sufficient conditions for local spectral approximation are then deduced, highlighting the wide.
The classical PWM method is deduced and its spectral characteristics are presented. Alternative local methods based on different approaches are then presented, highlighting the differences in the spectral performances.
The approximation of sets of quantities is then discussed, introducing the concept of variables transformation.
The simplest and most significant topologies of power converters are then presented.

Any student interested in developing their M.Sc. thesis on topics related to power converters and their applications is encouraged to stay in contact with the lecturer and to eventually attend also the optional module "Laboratorio di Convertitori, Machcine e Azionamenti Elettrici".
Further topics related to electric machines and drives are also available as M.Sc. thesis projects.
Thesis projects may be developed both internally and in collaboration with external companies, institutions and universities, also eventually including some stay periods abroad, for example in the framework of the Erasmus+ program.
