Deathla Coil v1 (DRSSTC)

Project Specs:

  • Months of work: Oct-Nov 2010
  • Approximate Build Time: 2 Months
  • Max Voltage: 0.5MV
  • Max Stored Energy: A few hundred joules
I got to MIT, and didn’t have any high voltage! Must fix this problem! This was my first project at MITERS.
I still can’t really believe this thing worked as well as it did, and that it never burned out. I don’t have a schematic handy, maybe I’ll make one someday. It’s just a current sensor shunted rail-to-rail, fed into a flip-flop, driving two UCC37322/1 chips, which drive gate drive transformers that directly drive the gates of a CM200TU-12F 3-phase IGBT brick. Basically the simplest DRSSTC that one can make.
Also had an arduino based interrupter that was able to play crude pre-programmed songs.
I also had to make a secondary, which I continued to use through DRSSTC v4. This entailed 20 hours of manual winding since I was too lazy to make a winding jig. A good activity for when I spent lots of time chilling at MacGregor (wtf, why do I live at MacGregor?)

The driver, bridge, and logic supply

All put together in a computer case

Don’t stop winding!

I’m done winding!

Yay, it works!

Can’t find a video of it, I’ll post it if I ever come across it.

  1. Just me again. I found your blog through a post
    This post, the Tesla coil must get your neighbors upset
    if the primary is at resonance the RFI will be way up there.

  2. There is some serious room for improvement in all your wiring. All wiring the supplies energy to the bridge and the primary circuit should be as low inductance as possible.

    • Yes, as you might guess by looking at the thing, this build was quick and fun rather than detailed and perfect.

      • I would like to use a few of your pictures in my DRSSTC design guide, not to point fingers, but to show some fall pits in low inductance design and dc bus filtering. I will credit you with name and link back for the pictures if you want that.

  3. I genuinely enjoy reading through on this internet site , it has great blog posts. “Do what you fear, and the death of fear is certain.” by Anthony Robbins.
