ECE 792E Syllabus

This course will focus on modeling, operation and control of power electronics converter systems. It will discuss state-of-the-art power converters and their applications in motor drives and utility grid interconnection.

Course Outline:

1. Introduction

  • Power Electronic Converters and their applications for grid connection
  • Three-phase converter circuits, modeling and control

2. Switching function theory of power converters

  • Mathematical representation of switching functions
  • Application of switching functions to dc-dc converters, and 1-phase and 3phase ac-dc, dc-ac and ac-ac converters

3. Three-phase modeling of converters

  • Synchronous Reference Frame (SRF) or D-Q modeling of converters
  • Vector / phasor representation of converter input and output variables

4. AC-DC converters: Rectifiers

  • Line commutated rectifiers – operation modes, modeling, harmonics
  • PWM rectifiers- operation, modeling, control, harmonics

5. DC-AC converters: Inverters

  • Three-phase D-Q modeling and analysis – inverter vector representation
  • Pulse-Width Modulation (PWM) techniques – quantitative treatment of PWM
  • PWM control of Voltage-Source Converter (VSC)
  • Inverter current control concept; Types of Current Regulators

6. Matrix (AC-AC) converters

  • Three-phase D-Q modeling, analysis, and duty cycle control

7. Resonant converters and Multi-level converters

  • Resonant DC Link converters and Resonant AC Link converters
  • Multi-level converter topologies : Neutral-Point Clamped (NPC) 3-level converter, Cascaded multi-level converter, multi-level converter cell concept

8. Converter application to drives

  • Vector control concept, and vector controlled VSC based induction motor drive – example of converter D-Q modeling and PWM current control

9. Utility interconnection applications of converters

  • Active harmonic filters – control, system application, issues
  • Instantaneous Reactive Power (IRP) theory and Synchronous Reference Frame (SRF) control for reactive power and harmonic compensation
