ECE 5274 - Modeling and Control of Three-Phase PWM Converters (3C)

Course Description

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.

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.
