Professor, D.Sc. (Tech.) Juha Pyrhönen
Upon completion of the course the student will be able to: 1. understand the role of electrical drives, 2. understand different torque producing principles in different machines, 3. model and simulate a DC motor drive, 4. describe the principles of scalar, vector and direct torque control of rotating field machines, 5. define and understand the functioning of the most important power electronic converters, 6. discuss the principles of PWM in general, space vector modulation and DTC, 7. model the behaviour of permanent magnet synchronous machine by using vector equivalent circuits and vector diagrams, 8. understand synchronous machine control in details, 9. understand synchronous reluctance machine control in details, 10. understand the role of induction machine and its control in details, 11. know the switched reluctance machine control principles, 12. discuss the adverse effects of PWM systems on motor behaviour and the wave nature of the motor cable. Mastering the course material well gives the student comprehensive understanding of the basics of electrical drives and wide possibilities to work in the field. This is the course for drives professionals.
