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'm 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.

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 our professional certificate in power electronics that

consists of three semester-long courses in this area.

So, this certificate will 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 the second course on Modeling and Control of Power Electronics.

For reference, we also teach a sequence of

four courses that leads to a professional certificate in

Electric Drive Train Technology for

electric vehicles including Basic Power Electronics for electric vehicles,

an AC Motor Drive course,

and some Battery Management courses.

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 percent of the questions correct.

We do allow unlimited attempts and I think trying

the homework again is one of the real ways that you learn in the course.

So, you may attempt the homework, get questions wrong,

you get instantly graded,

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 students integrated 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 one and then do

the module one homework assignment which is on

simulation of a boost converter using LTSpice.
