DC to DC Demystified - Blog 5 - Application description and part selection

Anthocyanina — Wed, 24 Jan 2024 21:47:43 GMT

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...(read more)

DC to DC Demystified - Blog 4 - Of common mode chokes and other transformers

Anthocyanina — Wed, 24 Jan 2024 21:46:44 GMT

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, ...(read more)

DC to DC Demystified - Blog 3 - Zener clamps and moving forward

Anthocyanina — Mon, 22 Jan 2024 02:56:26 GMT

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 ...(read more)

Flybacks from the Ground Up – Part 6 (Final): “… Landing is Mandatory”

Gough Lui — Sun, 21 Jan 2024 09:02:25 GMT

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 su...(read more)

Blog 2: Switching MOSFET's at +100kHz frequencies in high voltage environments - it's a precursor to getting Flyback Transformers to work properly.

BigG — Sat, 20 Jan 2024 22:44:21 GMT

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...(read more)

Flybacks from the Ground Up - Part 5: Going Back to Basics & Getting More Than I Bargained For

Gough Lui — Sat, 20 Jan 2024 12:31:08 GMT

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 ...(read more)

DC to DC Demystified - Blog 2 - Ring ring!? not today!

Anthocyanina — Fri, 19 Jan 2024 12:32:14 GMT

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...(read more)

Flybacks from the Ground Up - Part 4: Trying to Fly(back) & PLC Bode Plots

Gough Lui — Fri, 19 Jan 2024 10:42:46 GMT

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,...(read more)
