ECE 43300 - Power Electronics

Lecture Hours: 3 Credits: 3

Counts as:
EE Elective

Normally Offered: Each Spring

Requisites:
ECE 20002 or ECE 25500

Requisites by Topic:
Undergraduate Electronics Course

Catalog Description:
Introduction to the fundamental operating principles of power conditioning circuits that are currently being used to effect power flow from ac to dc and vice versa. Emphasis is on the relationship between form and function of these circuits. Circuits discussed will include ac/dc line-cummutated converters, dc/dc converters, dc/variable frequency converters, resonant converters, and ac/ac converters. Computer simulations will be used as a part of the course work.

Course Objectives:
To introduce the fundamental principles of operation of power conditioning circuits, concentrating on the relationship between form and function.
