Huge SCR

Wow. If this thing works, I may have got a pretty smokin' deal on a fatty SCR from the local electronics surplus shop: Apache Reclamation.

I found the datasheet online after a little bit of searching and found out it has these stats:

• 3000V Reverse voltage
• 2050A Avg. onstate current
• 19kA repetitive peak current
• 29kA surge current

WOW! This is THE SCR for some sort of heavy duty project (TMS machine, coin shrinker, can crusher, disc launcher, rail gun... etc!)

I'm guessing the broken lead is for the trigger ground or something? They don't have any physical diagrams on the datasheet.

Now I just need to find some low ESR capacitors and I'll have the biggest components of a really solid TMS machine.

All the parts are coming together...

4ga lead wire, SCR, 3 main capacitors (there are probably going to be 5 of those guys on the final machine), the Cockcroft-Walten voltage multiplier, the wooden main coil frame.

Walter-Cronkite voltage multiplier

Put this together today:




Charged some of the 'lytics that'll be used in the TMS machine.......

Catch 'em all

This is a pretty good diagram of what to do to in order to balance all your treatments.

Homebrew TMS Coil

used the thickest flat magnet wire from ElectroMechanicsOnline.
It's difficult to get a nice round coil because the wire is so hard to form, I used a wooden dowel with a hole drilled in the middle to create a form to wind a flat coil.

SCRs for the TMS machine

Received these C398 SCRs in the mail today. This TMS machine might actually come together :D

Simulated my TMS design!

After many hours of work last night/today, I've finally successfully simulated a monophasic TMS design in LTSpice.
Just need to get the capacitors and diodes for the voltage multiplier circuit and some heavy wire for the TMS coil and we can begin experimentation soon enough!

TMS to open up ambidexarity!
