### ECE 5254 Power Converter Modeling and Control (3C)

Nonlinear modeling of power conversion circuit using discrete and average techniques analysis and design of voltage mode and current mode control; parallel module operation and system interactions; distributed power systems; time domain simulation and frequency domain measurement techniques.

What is the reason for this course?

The growing energy shortage and continued environmental concerns related to energy genration and usage have stimulated the development and utilization of clean electric power in countless new areas now predominantly served by other forms of energy. Efficiency in the manipulation and control of electric power has gained increasing priority as the rising cost of power forces the abandonment of techniuqes which are short term cheap but long term wasteful. The course builds upon the introduction to power electronic circuits, taught in ECE 4224. It provides a comprehensive overview of recent developments in power converter modeling and control, concentrating on techniques that utilize pulse width modulation techniques.

Typically offered: Fall. Program Area: Electronics.

Prerequisites: 4224.

Why are these prerequisites or corequisites required?

Understanding of basic power switching circuit techniques, as covered in 4224, is required before beginning the study of a more advanced power converter and control techniques.
