Course objective:
To provide the basic theory for the dynamic analysis and control of AC drive systems employing power electronic converters and AC machines.

Course description:
Includes material on coupled circuit modeling of AC machines, power converters and converter modeling; simulation of drive systems; adjustable speed drive principles; torque control and field orientation; and small signal analysis of AC drives.

Prerequisite:
Basic course in electric machines (ECE 411), including in-depth treatment of steady state performance of induction and synchronous machines, or consent of instructor. Some knowledge of variable frequency operation is helpful.

Homework:
Problem assignments with answers for each course section (not handed in) plus 10 required problems to be graded.

Exams:
Two-hour cumulative final.

Laboratory:
None.

Computer software:
