ECE 534 Power Electronics
3 Credit Hours
DC and AC analysis of isolated and non-isolated switch mode power supply. Basic converter topologies covered include: buck, boost and buck/boost and their transformer-coupled derivatives. Design of close loop of these DC/DC converters. Power devices and their applications in DC/DC converters. Inductor and transformer design. Fundamentals of dc-ac inverters, ac-dc rectifiers and direct ac-ac converters and their applications.
Prerequisite
Undergraduate course in microelectronics and power electronics.
Course Objectives
This graduate level course is intended to develop an understanding of Power Electronics and switching mode power converters for various AC and DC applications. This course is intended to teach the fundamentals of power conversion and will cover the design, analysis, modeling and control of all types of power converters – such as, dc-dc converters, dc-ac inverters, ac-dc rectifiers / converters and also introduce the concepts of direct ac-ac converters.
The students will develop skills in complete design of these power converters through a project – especially focused on design of dc-dc converters.
This will be an important course for understanding of renewable energy interface to the grid, power converters for ac- and dc motor drives and power electronics devices and their controls. Aspects of magnetism basics, its application in design and understanding of working on magnetic elements such as inductor, transformer, etc. will be discussed in detail. Design oriented analysis will be applied towards control strategy and compensation design techniques.
