Selected papers - to be handed over in the class. 5. Evaluation Method. Assignments 3% Laboratory 10% Mid-Term Exam 35% Project 52% Total 100% 6. Each student will be assigned a project. Topics of projects will be discussed with each student around last week of June. Projects involve analysis, design and simulation or experimental verification of selected converter circuits. 7. Instructor: Dr. Ashoka K.S. Bhat, Room # EOW 413. e-mail: bhat@ece.uvic.ca Ph: 721-8682 Lectures: Section(s): A01 Days and Time: Monday 15:30 – 16:50 and Wednesday 17:30 – 18:50 (Room # ECS 130), 8. Contact (Office) Hours: Friday, 1:30-2:30 P.M.

Note: The time required for the experiments will be partially compensated by reducing the lecture time by about five hours. 9. Mid-Term Exam: June 26 (to be decided during the first week of lectures). 10. Learning Outcomes You will learn basic operation and characteristics of power devices (SCR, MOSFET and IGBT), and their use in power converters. You will also learn basic operating principles of ac-to-dc and dc-to-dc converters and dc-to-ac inverters, and how to analyze these converters.
