  • (01/12) Software requirements: a Spice simulator and MATLAB/Simulink. LTspice is the recommended free Spice simulator. Other Spice simulators are acceptable, but the instructor may not be able to provide any tool-specific support. MATLAB/Simulink are available to on-campus students in all computer labs, including the Power Lab and Circuits Lab computers. All students are entitled to purchase the student version which includes Control Toolbox and Simulink Control Design.
  • (01/04) The class starts Monday, January 14 in ECCS 1B12 (CAETE studio), 10-10:50am.
  • (01/04) A blog has been setup to encourage and enable both on-campus and off-campus students to post questions, comments, ideas, discussions or pointers to on-line resources related to course materials and homework assignments. Student registered for the course will receive an email invitation to join the blog.

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, and low-harmonic rectifiers.

Prerequisite: ECEN 5797. ECEN 5807 is offered in alternate springs, including Spring 2013. Instructor: Prof. Dragan Maksimovic. It is one of the three courses required for the Professional Certificate in Power Electronics.

The course is offered both to regular on-campus students and also to off-campus students via CAETE. Students registered through CAETE can receive lectures via videotape or DVD, web-based streaming video, or live TV. Further details of the course policies, including procedures for off-campus students, are listed on the Vitals page.
