Electric Power Systems module: Students will gain knowledge of the structure of electrical power systems, as well as the ability to recognize their main components, i.e., lines, transformers, and protection devices. Additionally, they will learn how to evaluate the performance of the last-mile electrical chain, comprising the transformer, the line, and the load, without and with power factor correctors or distributed energy sources. Power electronic converters module: Students will learn the basics of power conversion and the main topologies for this purpose. They will work out basic equations and practice with converter design from specs. This module will conclude with an introduction to modern power electronic devices. Converters for green sources of energy module: Students will learn which topologies are used for energy conversion from green energy sources, especially photovoltaic plants and wind farms. They will familiarize themselves with key concepts such as maximum power tracking, reactive energy control, and grid-connected converters, including related issues.

Math engineering, including but not limited to differentiation, integration, complex numbers, phasors, and frequency-domain analysis. Fundamentals of circuit theory, including magnetic circuits.

Lecture slides;

Exam: Optional oral exam; Computer-based written test in class using POLITO platform;

Exam: Written text and optional oral exam; The written test is a quiz including multiple-choice questions and numerical exercises. The written test lasts 1.5 hours. Grading and oral examination • The written test's grade range is from 1/30 to 30/30. • A minimum of 18/30 is necessary to pass the exam. • If passed, students may integrate the written test with an oral examination. • To pursue a with honors grade ("con lode"), students must undergo an oral examination. Oral examination typically comprises 1-2 questions on failed answers to the written test, if applicable, and an interdisciplinary question if a grade with honors is likely. Once the oral exam starts, the written exam grade will be withdrawn right away. Examiners have no obligation to take the written exam grade into account when grading the oral exam. Grades for the oral examinations range from 1/30 to 30/30, with honors.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
