Curso 1 de 6 en SpecializationPower Electronics

This course introduces the basic concepts of switched-mode converter circuits for controlling and converting electrical power with high efficiency. Principles of converter circuit analysis are introduced, and are developed for finding the steady state voltages, current, and efficiency of power converters. Assignments include simulation of a dc-dc converter, analysis of an inverting dc-dc converter, and modeling and efficiency analysis of an electric vehicle system and of a USB power regulator. After completing this course, you will: ● Understand what a switched-mode converter is and its basic operating principles ● Be able to solve for the steady-state voltages and currents of step-down, step-up, inverting, and other power converters ● Know how to derive an averaged equivalent circuit model and solve for the converter efficiency A basic understanding of electrical circuit analysis is an assumed prerequisite for this course.

Dr. Robert Erickson
Professor
Electrical, Computer, and Energy Engineering

Welcome to course one, Introduction to Power Electronics.

I'm Professor Bob Erickson.

I am in the Department of Electrical, Computer and

Energy Engineering at the University of Colorado at Boulder and

I co-direct the Colorado Power Electronics Center.

I want to briefly discuss just a few of the practical

aspects regarding this course.

So first of all, we have an optional textbook that is written by me and one

of my colleagues teaching this course, called Fundamentals of Power Electronics.

It's listed here.

You don't have to buy any textbook to take this course.

And we will post slides and have videos for all of the material in the course.

The course will closely follow some of the chapters of this textbook.

The assumed prerequisite knowledge for this course is that you've taken

a sequence of circuits and electronics courses, such as that,

that an undergraduate electrical engineering major would take.

Of course, you don't have to take any courses in order to sign up

through Coursera.

However, when we teach this material on campus, we find that those students

who don't have this prerequisite knowledge do have difficulty in the course,

and especially starting in the second week.

Just for reference, here is the curriculum in power electronics that we teach at

the University of Colorado.

We have a professional certificate in power electronics that consists of

three semester-long courses in this area.

So this certificate, we'll cover at a fairly fast pace the first

semester-long course called Introduction to Power Electronics.

And the certificate also has some material out of this second course on Modelling and

Control of Power Electronics.

For reference, we also teach a sequence of four courses that leads to a professional

certificate in electric drivetrain technology for electric vehicles.

Including some basic power electronics for electric vehicles,

an AC motor drive course, and some battery management courses.

And then finally we also teach a laboratory course, in which students build

a standalone solar power system, including the power electronics.

This course will have one homework assignment per week.

And to pass the homework assignment,

you have to get at least 70% of the questions correct.

We do allow unlimited attempts.

And I think trying homework again is one the real

ways that you learn in the course.

So you may attempt the homework, get questions wrong,

you'll get instantly graded with machine grading.

And you can see where you went wrong and try again.

We have not watered down the course, this is full strength.

And the homework assignments are of a fairly high and challenging level.

So these are real assignments such as ones that we would give to our on campus core

students in a graded course.

There are also in-video quizzes that are very short questions.

These are not graded, you don't have to do them to get credit for the course.

But they do reinforce specific points that are related to the lecture and

I think they are useful.

So, what's on the Coursera website?

We have the recorded lectures.

These lectures are arranged in one week modules.

So there are three modules for this first Introduction to Power Electronics course.

Also linked are the slides used in each lecture.

There are the homework assignments, one per module.

We have some solved sample problems that can help in understanding the homework,

and there are simulation files on the website as well.

So for the first week of class, your assignment is to view the lectures for

Module 1.

And then do the Module 1 homework assignment which is on simulation of

a boost converter, using LTspice.
