The major focus of this course is on design oriented analysis of topologies and control methods for various power electronic converters used for dc-dc, dc-ac and ac-dc power conversions in important and current applications, and power systems harmonics. This course is intended as a second course in power electronics. However, several lectures are devoted initially to the fundamentals of switch-mode power conversion such that students can follow the course easily. PSpice based simulations are used extensively to reinforce the basic concepts, and as a design tool as well. Power semiconductor devices such as MOSFETs and IGBTs are also discussed briefly.
