Aims 

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 the most important power electronic converters, 6. discuss the principles of PWM, space vector modulation and DTC. 7. model the behaviour of permanent magnet synchronous machine by using vector equivalent circuits and vector diagrams.

 
Contents 

Theory of electric motor drives, operation and vector equivalent circuits. Torque production in different machines. Power electronic converters suitable for motor and generator drives. Scalar control, vector control, direct flux linkage control and direct torque control (DTC). Permanent magnet synchronous machine drives.
