ECE 4224 Power Electronics | ECE | Virginia Tech

Undergraduate PROGRAMS

Course Information


Power devices and switching power converters including rectifiers and inverters; design of electronic power processing circuits and their control as applied to computer, telecommunication, transportation, and industrial systems. A C- or better is required in all prerequisite courses.

Why take this course?

This is the only undergraduate power electronics course except for the accompanying Power Electronics Lab 4284, which students may take concurrently with this course. This course serves to introduce power electronics to the undergraduate students as well as to supplement the background of graduate students who will use the concepts from this course during their graduate studies. Power electronics as the enabling technology for most of the electrical and electronics industry is a rapidly growing field within electrical engineering. It is also a prominent strengh of the ECE Department at Virginia Tech.

Learning Objectives

  • 1. Analyze basic operation of switching power converters.
  • 2. Simulate detailed, average, and small-signal operation of power converters.
  • 3. Use steady-state, average, and small-signal models of PWM switch in power converter analysis and design.
  • 4. Design power state of dc-dc converters for dynamic specifications.
  • 5. Design feedback controller of dc-dc converters for dynamic specifications.
  • 6. Design inductors and transformers for high-frequency power converters.
  • 7. Select a dc-dc converter topology suitble for a given application, design the complete converter, select all components, and verify the design through computer simulations.
  • 8. Organize and write technical reports.
  • 9. Organize and make technical presentations.
