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
