ECE 5274 - Modeling and Control of Three-Phase PWM Converters
Power conversion principles for three-phase pulse-width modulation techniques, control and converters. Development of averaged models of three-phase rectifiers and inverters in stationary and rotating coordinates. Small-signal models in rotating coordinates and control design. Introduction of switching state vectors and different modulation schemes. Three-phase inverter and rectifier applications. Parallel and multi-level three-phase converters.
Why take this course?
Three-phase converters cover most medium and high power applications in the power electronics area. There has been no such course in this university; the course 5254, Power Converter Modeling and Control, covers only the material related to the dc-dc converters. However, over 30 graduate students are doing research in the area of three-phase power conversion.
Prerequisites: ECE 4224 or equivalent
This course requires 4224 as a prerequisite. 4224 covers the average and small-signal modeling of generic switching cells, and basic principles of closed-loop control design and PWM techniques for dc-dc converters.
Major Measurable Learning Objectives
Explain operation principles of three-phase PWM converters;
Use different modulation techniques to generate PWM for three-phase converters;
Design closed-loop control for three-phase PWM converters, and;
Select and design converters for medium and high power applications.
