Introduction to the Specialization and the Course

Welcome to the Modeling and Control of Power Electronics Specialization. The Specialization consists of 5 courses:

1. Averaged-Switch Modeling and Simulation

2. Techniques of Design Oriented Analysis

3. Input Filter Design

4. Current-Mode Control

5. Single-Phase Rectifiers and Inverters

Averaged-Switch Modeling and Simulation, the first course of the Specialization, consists of three weeks of course materials. After completion of this course, you will be able to practice design of high-performance control loops around switched-mode power converters using design-oriented analytical and simulation techniques. The for-credit version of the course (ECAE 5705) includes a practice exam and a final exam in Week 4.

In Week 1 of Averaged-Switch Modeling and Simulation, we start with a review of materials covered in courses: Introduction to Power Electronics, Converter Circuits, and Converter Controls. Modeling and control techniques are briefly reviewed, including analyses of converter transfer functions, design of control loops and converter frequency responses using MATLAB, as well as performing design verification by Spice simulations of closed-loop regulated converters. Week 1 includes application examples and practice Quizzes, and concludes with a graded Quiz on Introduction to Modeling, Control and Simulations.

In Week 2 of Averaged-Switch Modeling and Simulation, a design-oriented analysis technique known as the Middlebrook's feedback theorem is introduced and applied to analysis and design of voltage regulators and feedback circuits commonly found in practical circuit implementation of control loops around switched-mode converters. Week 2 includes application examples and practice Quizzes, and concludes with a graded Quiz on the Feedback Theorem concepts and applications.

In Week 3 of Averaged-Switch Modeling and Simulation, it is shown how circuit averaging and averaged-switch modeling techniques lead to converter averaged models suitable for hand analysis, computer-aided analysis, and simulations of converter steady-state, transient and frequency responses. Week 3 includes application examples and practice Quizzes, as well as a graded Quiz on Averaged-Switch Modeling and Simulations.
