There are multiple things I did forget to add. Read description for more. Timestamps and subtitles included. Thanks a lot for watching! I hope you were able to achieve your dreams of owning a powerful IGBT driver to be able to do anything you want! Use them as a "VFD" for AC motors etc especially! AC is AC. Now, have fun with them! Technically, it took me TWO YEARS to finally make this video. (But actually a month and a half to make this video, it's mostly the voice overs that I had to do.)
This video was put together really well, I was able to pick up some idea of how these work. Been very lazy to figure these out on my own, this makes it understandable. I bet it took ages to edit, but this was good enough to keep me to the end!
@VariacManiac you'll need a gdt, sstc are a couple hundred kHz or less depending on how big. If it's a small sstc you'll need smaller igbts for much higher frequencu
That is awesome, I'm inspired to continue with the hobby, i was not touching it for more than a year now. I want to build some big ass HF arc generator. Thanks a lot. You are a rock star!
Thank you! That is so cool, and if you see this comment I wanted to ask you something. So I am the crazy MOT kid who didn’t know how to wire a MOT and thought you could see “HHO” and started fights in your discord. Since then I have apologized to all the people in your discord. They have taught me the basis of basics of electronics, and I have built Tesla coils and made my own flyback transformer. I was wondering if I could get back in your discord?
Looks like you rectified the AC to DC using diodes and huge capacitors, I would imagine your neighbors' AC waveforms, All flattened near the peaks, due to your capacitors only drawing (astonishingly high) current near the AC peaks. Great time to learn about Active Power Factor correction.
Ehh. I use a variac to control voltage, so not really. It still draws quite a bit of current, I can feel/hear my smaller variac whining as I increase the voltage a little quicker. It stops when I stop.
That was awesome, I see a lot of work went it to making it definitely thumbs up 👍👍👍👍👍 A few years ago I built a SLR full bridge converter with TO-247 IGBTs, works to this day! One day I want to build a bigger driver!!!!!
Have you tried one of SG3525 driver boards with an op-amp and optocoupler feedback loop for your full bridge? There are many versions of them on aliexpress, they are cheap, mostly similiar circuits, and allows to use frequencies from tens to hundreads of khz. I am wondering how to use one of them in HV PSU to get a stabilized, regulated output with constant voltage/ constant current option, for x-ray experiments.
Thanks ❤ very rare video! Opto doesn't need regulated voltage from linear voltage regulator? Don't need negative gate voltage to turn off igbt? Please repost schematic i haven't telegram
Why do you seem to like series resonant half bridges? With parallel resonant half bridges with DC blocking capacitors the IGBTs don’t need to handle the entire resonant current.
@@trenthighvoltage I will watch your video 50 times and not be the gangsta you are with high voltage. It took you years to get this good. Keep up the excellent work! Bummer, I can't buy something close to your fantastic circuit.
@@trenthighvoltage hfvttc bro🙏🙏🙏🙏 at least explain how that works. Pleasee. Especially about the resonator, how the flame appears and how it oscillates(i dont get how a grid cap discharges)
The SG3525 oscillator has a rating range of 100hz to 400kHz. It could do as low as a few Hz, and as high as 550+ kHz as far as I can remember. You need IGBT bricks or smaller packages that can switch at that high frequency.
@AZhang728 why wouldn't you want to use a full bridge rectifier? Get full wave and more pure dc? Do whatever you want, I don't see why you.would want to use a single diode or something
Pls make sure you ARE using a genuine 3525A or better still a 3525B...& not just 3525.... The " B" version is the upgrade of the "A"..whilst the original was just 3525..... Check all 3 datasheets to compare differences....You may want to look up the ML4818 controller... This has dead time built into 4 dedicated outputs and is current mode controlled , unlike the3525 voltage mode chip.. The 4818 is ideal for resonant topology.
i dont dislike the video or anything, i thinks its good and talks about whats going on, i just think that you may need to invest the time into a script. i feel like you realised a bunch of mistakes while cutting, and decided to fix it in post, it feels like there too many jumpcuts
My only real question...why do you need this 😂 just like watching plasma ? Or are you going to build something of your own desgine that requires this or just more tesla coil stuff thats all over the net, maybe long range radio or something ? Dont get me wrong, im an engineering student so i understand the importance of lessons in this. Im just asking whats your personal goals with this project 😂 This type of shit is a 1 way ticket to jesus 😂
