EDUCATION

Modeling & Control Design of DC/DC Converters

Instructors: Fred C. Lee and Qiang Li
Dates: July 28th - August 1st
Lectures: The Inn at Virginia Tech, Room: (TBD)
Lab: Whittemore Hall, Room 253

Course Description

This course includes DC/DC converter analysis, modeling, simulation, control design and frequency domain measurement techniques. Participants will receive hands-on guidance in the lab to solve design challenges using control methods for Buck and Boost converters, including peak current-mode and voltage-mode control. They will explore the impact of loop-gain design on performance metrics and gain a solid understanding of power converter control through dc and ac characteristic analysis through the following topics:

  • DC and steady-state analysis of PWM converters - forward and flyback converters, DC characteristics, PWM controller operation
  • Modeling and analysis of PWM converters - average modeling of PWM converters, small-signal modeling of PWM converters, open-loop small-signal and transient characteristics
  • Single-loop control for PWM converters - loop-gain, phase and gain margins, design of single-loop compensators, closed-loop, small signal and transient characteristics
  • Advanced current-mode control - peak current-mode control using standardized control modules (SCM), average current-mode control, charge control, constant on-time V2 control
