YouTube playlists and lecture series on using the simulator

I reorganized my YouTube channel into playlists:

So now there is a playlist for every topic rather than just a collection of videos. I am trying to break the videos up into pieces as it is easier to record them and also upload them on YouTube. A playlist ensures everything is in order inside a topic.

Recording videos has been a learning experience. I am gradually getting the hang of using recording and editing software. I use Kazam in Linux to record the screen while programming or going through slides. I use Kdenlive to edit the videos. Initially the videos needed only a clipping of the last extra seconds. Now I need to boost up the volume as I find the volume is quite low. Also as simulations will get longer, it will be needed to pause the video often and that means cut out parts that are just pauses.

The first major lecture series is one on how to use the circuit simulator web app version. How to install the circuit simulator is a separate playlist:

This playlist contains videos on how to install Python Power Electronics in Windows and Linux.

The lecture series on how to use the simulator should be watched after you have installed a version of the circuit simulator on your system.

The circuit chosen is a single-phase diode bridge rectifier with a dc capacitor at the output. The load consists of a constant resistor load and a switched resistor load. The first part of the lecture series describes the simulator without using any control functions. The latter part of the simulator describes how to write control functions. The main emphasis here is on the special variables that can be defined with control functions and how they are to be used.

As time goes on more detailed simulation results will be described in the videos. For now the above tutorial is to get you started with Python Power Electronics so that you can use it for your own projects. The video lecture references two short papers that are available on my website:

And of course for details on the simulator and how control functions are processed or the user interface is handled, check out my book:

The book contains entire chapters on user interface, control functions and an entire example on how to simulate a reactive power compensator for a three-phase distribution system.

Making videos is fun and I will continue making them. I feel that videos engage people much more than documents or even slide shows. Stay tuned for more videos on the YouTube channel:
