ECEN 5807 Modeling and Control of Power Electornics Systems

Advanced modeling and control topics in power electronics, and power factor corrected supplies. Averaged switch modeling of converters, computer simulation, ac modeling of the discontinuous conduction mode, the current programmed mode, null double injection techniques in linear circuits, input filter design, harmonics in power systems, low-harmonic rectifiers, and introduction to digital control.

Prerequisite: ECEN 5797 Introduction to Power Electronics

Required Textbook: Erickson and Maksimovic, Fundamentals of Power Electronics, 2nd edition, Springer Science+Business (2000), ISBN 0-7923-7270-0. Can be ordered from the University of Colorado bookstore (same text as ECEN 5797).

Computer requirements: Access to web is required. A Spice simulator and MATLAB/Simulink are required. LTSpice and MATLAB/Simulink are available to on-campus students on Power Lab and Circuits Lab computers; contact the instructor if you need access to these labs. LTSpice can be downloaded by anybody for free using the link above. The student version of MATLAB/Simulink is sufficient; this can be purchased online or through the campus bookstore, if desired; if you are enrolled in this course then you are eligible to purchase student MATLAB. Use of a simple spreadsheet, such as Excel, may be helpful but is not required.
