With the Buck converter it works without one too. But the flash cap increases the discharge energy and makes the feedback a little smoother. It is basically a leftover from the early stage of the board.
The board is powered by a DPM8605. So 60v@5A is the maximum. The board itself is designed to take much more than that. 100v @ 10A should be no problem with good mosfet cooling. (constant current, not just peak) But I never tested it. At higher frequencies it will start to suffer from parasitics and the duty cycle gets off. But 0-70khz is acceptable stable. With correct settings it produces microscopic sparks that are barely visible. Did one test with 200khz and it did produce very smooth sparks but don't know what the real output frequency would be if monitored by a scope. A normal multimeter starts loosing track of the frequency at around 70khz. I personally don't use frequencies above 20-30khz.
I spend a huge amount of money to get this thing running and would like to get some of it back before the files are released. Hope you can understand. But at the end the gerber files will be shared too.

Photo flash capacitor this is simple and a great idea !

Hi would you please share the spec of the board in terms of input and output voltage and amperage and pulse frequency

@G-EDM Thank you very much my friend, and impatiently waiting for updates 🙏
How does one have fun? Where can I get a board?
At the moment the PCB gerber files are not public. They will be at some point. But you can contact me at goblin-dev@proton.me for more details. ;)
They gonna spam u
Not a single spam mail yet. :D I'm a nobody.@@KEKELI.D
Is there a schematic for the circuit sir?

Hello, I'm interested in circuits for wire cut EDM. Do you sell them? and request a contact channel
Currently there is no sale. But there will be soon.
