The course aims at providing to the students the basic concepts of the electrical energy conversion systems employed in transportation electrification, with a particular focus on hybrid and electrical vehicles. The systems under study will be the electrical drives for powertrains and the battery chargers. The electrical motors belong to the new generations of eMotors dedicated to electrical traction, such as induction motors, synchronous reluctance motors and internal permanent magnet motors. The course will provide also the basic concepts of vector control of traction drives, along with testing techniques to obtain efficiency maps and torque production maps.

The exam consists of a written test of 150 minutes, containing multiple choice questions (24 points) and three fast numerical computations (6 points). During the exam, the use of books, notes or equivalent materials is not allowed.
In addition, during the teaching students will be given a report to be elaborated at home, regarding the sizing of an electric drive and the design of the its torque control scheme. The report is rated up to 30 points. The final score is calculated as the weighted arithmetic mean between the written test (80%) and the score obtained for the report (20%).
The rules of examination are described and discussed during the introductory class.
