What is Experimenting with Flyback Transformers?
Flyback transformers are used in switched-mode power supplies, converters, inverters, and much more. They are a unique device, They function as an isolated inductor, storing energy in every cycle. (A…

I've been called weird a fair number of times for carrying a multimeter or screwdriver in my backpack to a social outing. I think that's just basic everyday stuff to carry around, but people just don't get it. Anyway! I decided that instead of trying...
In the previous blog I mentioned we were going to take a quick look at calculating common mode filters. Unfortunately, we're going to have to skip that bit for now as I was unable to get a complete understanding of how to design common mode filters, ...
This is the mandatory Final Results Blog for Experimenting with Flyback Transformers.
I cap up my participation in this design challenge playing with common mode chokes and AC-DC flybacks. I am not submit...

Previously, we learned how to take care of the high frequency ringing using a primary side RC snubber across our switch, but there was still a voltage spike that, while for the test circuit is fine, can really get to dangerous levels if we were ...

Introduction
Intentional instability. According to Wikipedia, this is a highly sought after feature in fighter aircraft design. I think, based on my experiments so far, I could say the same for flyback transformers!
As with many other flyback transf...
This blog 3 is related to my Self-Claimed Method, submitted to an International Scientific Community in Jan. 2022. Also, in this blog, I will explain design examples and basics, with how to select components and flyback transformer practic...
After my hubris in the last posting leaving me with egg on my face, I decided I would need to go back to basics. After all, the saying is that you need to learn to walk, before you can run (or fly), so it’s time I try the most basic of flyback ...
Previously we explored the very basics of getting a flyback converter up and running, but by the end of it, real world components showed us it wouldn't be so easy after all... But do not despair! Physics may have pulled a fast one on us, but we can u...
After some rather anti-climactic abuse and safety tests which put me at ease, I decided it was time to fly even before I could walk so to speak … in the name of flybacks. After all, I got a late start to this challenge and time is running out,...
Now that I’ve looked at the basics of flyback topology converters and performed some basic measurements, it’s time to start some experiments. But unlike most posts, somehow I woke up this morning and chose violence against flyback transfo...
In this Blog 2, I will describe the flyback smps technology. When I had applied for this design challenge, I didn't thought of writing any special blog for this, as all materials are available on net but the motivation of writing spec...
In the last blog, I mainly looked at the specifications and unboxing of the transformers included in this Experimenting With Design Challenge. In this section, I’ll be tackling questions about what a “Flyback” is and doing some basi...

This being my first blog, i'll begin with a short introduction:

Introduction
We all start with an idea and a plan. I started with an inkling of what flyback transformers were about, having seen common chokes being used for isolated signal coupling, and I had an itch I wanted to scratch.
I wanted to see if I could...
Hello Everyone
This is my 3rd design challenge with e14 (I had withdrawn from the Ist one but I have done new research on it, which can be found in my preprint research papers list and 2-3 more would be added).
Thanks for organizing&nb...
Some of you requested the optional power adapter in your application forms.
We have them now and will be shipping them to the participants that had requested them.

What Is so special about a flyback transformer?
The simple answer is how energy is stored in the gap of its core. Basically, it is a coupled inductor with a gapped core. During every cycle, the input voltage is applied to its primary winding. Energy...
