Course Description

This course introduces you to the basics of Power Electronics including switches, Inverters, DC/DC converters and all that supported by LTSpice. We cover here how to calculate the power dissipation and thermal stresses for different groups of waveforms on switches by hand and using LTspice. That includes sizing the heat sink and enabling you to decide whether active cooling is required. We introduce you to Silicon, Silicon Carbide and Gallium Nitrate switches and the main differences to enable you to choose the best for an application. You will be able to analyse the DC/DC Converters: Buck, Boost, Buck-Boost and inverters and understand how the current flows in a circuit and to derive the steady state relations between the input and the output.

LTSpice is used to validate the calculation and help to calculate a converter efficiency. We use LTSpice to design a closed-loop Buck converter. All that is supported by problem sets and labs. Problem sets are a group of problems that we supply for you to practice your understanding and we supply also the solutions. For the labs we introduce you to some tasks that will help you to conquer LTspice.

We are expecting you to engage totally with the course and give enough time to understand each part and practice the problem sets. I am confident that will be an excellent course for you to understand any more advanced topics in power electronics.

Don’t buy this course as it is free on YouTube . I feel scammed

By Bart Mellenbergh on 12/8/2025

I have an interest in electronics but no electronics education. The lucid explanation that Walid gives provides me with the necessary understanding not only how a certain circuit works but why it works, based on the operational characteristics of the constituent components, and why you might consider such a circuit and not others.

The simulator program is good. Your knowledge of electronics is also good. This course had a very high amount of math that sometimes took some time to absorb and understand.

By Sunney Kumar on 4/13/2025

This course covers from basic to little advance level. It is a good refresher for experience engineers and must watch for beginners. The LTSPICE tutorials in between are cherry on the top.

By Roberto Santiago on 12/14/2024

Your course expanded my knowledge. There were some aspects that I did not learn in college that I was able to learn and understand through your videos.

By Vincenzo Aprea on 5/14/2024

This is a great experience for me , very good teaching, the arguments are very complete for a basic knowledge of Power electronics and explained simply. I'm very satisfied.

Fantastic course! Walid explains inverters and converters with great depth. Using LTspice made grasping electronics concepts much simpler. Would strongly suggest folks to enrol in this course.

By Filip Garmaz on 9/23/2023

This course was very well done. The lessons were detailed and the concepts of power losses and how to calculate them were well explained. The only thing I didn't like about the lessons is that some lessons were too monotonous, theoretical and abstract (especially high-order math/calculus equations). I also really liked the tasks and problem sets after every few sections. The tasks were not too easy, but not too hard either, which made them challenging to solve. I like how those tasks can make participants actively think about power electronics problems and how to solve them. Overall, this course is worth taking, because even though it can sometimes be hard, it makes one really learn what to consider when designing circuits to avoid overheating components and wasting power.

A very informative course with relative Powerpoint Presentations. The tutorials in between are great as they help to implement the learned objectives in reality. The linking of course learning to the practical world is something I enjoyed the most. I deduct half a star because I believe the Lectures could have been made better and more professionally and audio quality could be improved too.

By Mark Gillis on 1/10/2023

I found this to be a great course with excellent content. The instructor provided very clear and to the point explanations and examples. I took off 1/2 star because I would have liked to see the content expanded (or an additional course provided ) to include the theory, principles and practical considerations behind the magnetics required for the converters, information regarding the control loops, converter stability, (e.g. loop differences between CCM and DCM modes), transient response topics, AC analysis and similar content for isolated converter topologies, e.g. forward, flyback, push-pull, etc.
