Subject fundamentals
The subject is offered as a free-choice module. The subject aims at providing the basic concepts relating to the electronic power converters for feeding electrical motors. Moreover, the subject studies the electric drives with DC motors and AC ones, with particular attention to the new generation of electrical machines, as the reluctance synchronous motors and internal permanent magnet motors. They are presented motor control strategies the design of the control loops of an electric drive (current, speed and position).
Expected learning outcomes
Applicability and performance evaluation of electric drives. Ability to understand the typical problems of the use of electronic power converters in electric drives. Ability to compare different solutions of electric drives based on different types of motors. Capacity to design or to tune the control loops of an electric drive.
Prerequisites / Assumed knowledge
Fundamentals in electrical circuits, electrical machines, automatic control or the basic concepts in systems theory.
Contents
? Introduction: general description of an electric drive
? Power electronic devices used in power electronic converters
? Elementary DC / DC converters: principle of operation of a switch-mode converter
? DC / DC converters for electric drives
? DC / AC (inverter) for electric drives
? Front-end AC / DC converters and their influence on the mains power
? Modelling of mechanical systems
? Control of electric drives: design of the control loops of a drive with cascaded current, speed and position control loops
? Brushless DC motor drives
? Induction motor drives with scalar control
? Fundamentals of vector control of AC motors
? Vector control of sinusoidal brushless motor drives
? Vector control of motor drives with reluctance synchronous motors with permanent magnets and interior permanent magnets
? Vector control of induction motor drives
Delivery modes
In addition to classroom lectures, laboratory activities are planned. The laboratory exercises concern the analysis of the operation of an electric drive with DC motor and a drive with permanent magnet motor.
Texts, readings, handouts and other learning resources
Texts required or recommended: readings, lecture notes, other teaching materials.
Suggested books:
(1) N.Mohan, T. Undeland, T. Robbins "Elettronica di potenza : convertitori e applicazioni", Hoepli Milano, 2005 (italian)
(2) M. H. Rashid, , 'Elettronica di Potenza', Prentice Hall, 2008 (italian).
The same books are also available in English.
Assessment and grading criteria
The rules of examination are described and discussed during the introductory class. The exam consists of a written test of 150 minutes, containing multiple choice questions (24 points) and a question with open answer (6 points).
In addition, during the teaching students will be given a report to be elaborated at home, regarding the sizing of an electric drive. 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%).
