ECE 4224 Power Electronics (3C)
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.
What is the reason for 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.
Capstone Technical Elective for EE; Technical Elective for CPE. Typically offered: Fall. Program Area: Electronics.
Prerequisites: C- or better in 3204 and senior standing.
Why are these prerequisites or corequisites required?
Due to the multidisciplinary nature of the subject, this course requires senior standing and background in the solid state device characteristics and electronic circuit design techniques, which are taught in 3204, Analog Electronics.
