Dual Resonant Solid State Tesla coils / Re: Is one of these good?
« on: June 23, 2019, 07:22:47 PM »
Yes I'm thinking that I will be supplying a full bridge with a maximum of 230Vac.

That's why I was wondering about adjusting the ODC to 300A.

I have not gone any further in design or construction due to forced trips away from home.

I'm almost there.

Just a few more questions....

1) mmc:
CDE 940C20P15K-F FILM 0.15UF 10% 2KVDC AXIAL
   2 parallel strings of 4 in series for 0.075 µF
                         - or -
   can  I get by with 2 in series for 0.075 µF

2) I would like to use ass many off the shelf products as possible:
  Current Transformers - Magnetics CST206-1A for 1:100
  Gate Drive Transformers - GT04-111-063-B P0584NL 

3) Gate Drive Resistors - 15 ohms

4) OCD:
  Is 300A too high or should it be set into the high 200s


Thanks again

Home for a day to run some numbers.

What do you all think about these numbers?
And is the system too much for my planned FGH60N60SMD full bridge system operated with 230Vac input?

THANKS...........
Great stuff which will get me off in the correct direction.

I've been called away from home for an emergency and will be away for a few weeks.


As soon as I return I'll start re calculating and be back with more questions.

I’ve calculated  and re calculated my system (keeping the fo around 225KHz) and cannot make a flat primary with more than 3 or 4 turns work with larger caps than my original 0.05 uF.

It seems to me that by going to a vertical primary I can make 0.15 uF work.

How does this look now?

Dual Resonant Solid State Tesla coils / Is one of these good?
« on: May 14, 2019, 04:21:07 PM »
OK so as I continue to think about my FGH60N60SMD full bridge system I'm thinking about these two coils.
One has a 1/8 inch tube primary and the other has a 1/4 inch tube primary.

Would either of these be a good choice for my DRSSTC system?

Comments please,

Dual Resonant Solid State Tesla coils / Just how large?
« on: May 13, 2019, 03:04:50 PM »
Hi all,

I'm in the planning stage of my first DRSSTC system.
I'm planning on starting with a bridge of 4 FGH60N60SMD -or- FGA60N65SMD components as I want to stay with the TO-247 size for my first system.

My original desire was to use a 3 1/2 inch secondary coil form with a 1/4 inch copper tubing primary (which could be used for larger systems) but I'm wondering if this might be too large for my planned bridge.

In browsing the web I've found lots and lots of 2 3/8" dia. secondaries based on my choice of components and now I'm wondering if the 2 3/8" dia secondary might be the optional size.

So my question is just how large of a system will a bridge of 4 FGH60N60SMD -or- FGA60N65SMD support.
