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…

Design Challenge: Experimenting with Flyback Transformers Title: EMC-Optimized SMPS for PEMF Therapy device by Kamrul Hussain Blog: 0 - Introduction Date: 23 Jan 2024 Introduction: Sorry for my late start. I received the kit vary late due…

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 to use…

My five optional blogs are in and it’s time to cap it off with a (mandatory) final blog, adhering to my “one blog a day” cadence to ensure I can deliver in time. As this blog needs to be standalone, it will be a slightly abridged summary of the points…

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 circuits…

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, meaning…

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 transformers . This…

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 basic measurements of parameters…

Thanks to element14 and Bourns for selecting me as one of the challengers for the Experimenting with Flyback Transformers Design Challenge. Power conversion is a key part of modern electronics designs and almost every low-power, low-cost, energy-efficient…

Do you know the answer to this question about flyback transfomers? If you understood the question and answered (c), please read on. You are the talent I am looking for to participate in element14's Experimenting with Flyback Transformers program!…

Can you answer this question about flyback converters ? If you answered (b) and are interested in experimenting with flyback transformers, you might have what it takes to be part of element14's Experimenting with Flyback Transformers competition …
