Modeling & Control Design of DC/DC Converter

Lectures: Cascades Conference Room, The Inn at Virginia Tech (IVT) and Skelton Conference Center
Lab: 253 Whittemore Hall (within walking distance to IVT)
Instructors: Fred C. Lee, Qiang Li

Course Description

The course will engage engineers in a combined lecture/laboratory instructional format, providing hands-on experience in the DC/DC converter analysis, modeling, simulation, control design and frequency domain measurement techniques.
