• Capability to understand the structure of a traction electrical drive consisting of battery, power electronic converters and electrical machines. • Ability to compare different electric drive solutions based on different motor technologies. • Ability to provide the right specifications for the components of an electrical powertrain, according to the vehicle specifications. • Capacity to develop or use proper simulation models for the simulation of power converters and eMotors that must be embedded in larger vehicle models. • Capacity to calibrate the vector control for an AC motor taking into account the motor flux maps and the sampling/switching frequency • Capacity to design the control of power converters for traction applications.

Fundamentals in electrical circuits, electrical machines, automatic control or the basic concepts in systems theory.

• Introduction: general description of an electric drive • Power electronic devices used in power electronic converters • Basic operation principles of a switch-mode power electronic converter. Canonical commutation cell. • DC/DC converters for eMobility. • DC / AC converters (inverters) for eMobility. • Electrical motor solutions for eMobility: induction motor, synchronous reluctance motor, internal permanent magnet motor • Fundamental concepts of vector control for AC motors fed by inverters • Vector control of eDrives: design of the drive control loops (current, speed and position). • Implementation issues of high performance vector control of eMotors: Maximum Torque per Ampere (MTPA), Maximum Torque per Volt (MTPV), torque estimation, computation of maximum torque according to the voltage and current limits • Traction battery: technologies, rated parameters, charging modes. • Battery chargers: on-board and off-board solutions.

In addition to classroom lectures, laboratory activities are planned. The laboratory exercises concern the analysis of a three-phase inverter and the operation of an electric drive with internal permanent magnet/synchronous reluctance motor.

Exam: Written test;

The exam consists of a written test of 150 minutes, containing multiple choice questions (24 points) and a question with open answer (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.

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.
