All,

Sorry about the oversize picture, forgot about downsizing on my MAC.

You can still edit your post. In the upper right corner (of that post) click modify and uncheck the first picture and upload the re-sized one and click save.
It will help all who come to read this page.


Thanks for your help

Hi Luc,
Fixed that huge picture.  Should make everyone's life easier.
I eventually will make that driver using a "H" bridge. Or as I like to
simplify things, do it another way.   

Everything circuit wise in the Gunderson device suggest that it was simply designed to
vary a magnetic field back and forth in a ferromagnetic magnetically biased core and in magnets with
a transformer and at a certain point in time, at a particular point in the varying field,
you hammer that field with a very high voltage relative high speed pulse. From the time you pulse it, till the start
of the next repeating cycle, power occurs and is extracted from this core/field, etc. 

That Gunderson chose to use a H bridge and a complex rectification system, etc. would appear
to be just one way of doing it.  The REAL question is......What are the characteristics of the power output pulse?
Everything else is just circuitry to get the core/field to release this energy with the least amount of work to do it.
Circuitry is circuitry, When you Google "H Bridge drivers in Tesla Coils" you get hundreds of variations on a theme.
We are running around in circles trying to figure out exactly how his circuits work, but we need to more know
how is the power generated by his waveforms. Look at the wave, not the boat!

Respectfully,
Ben K4ZEP

I've been going over some pix I've received of the breadboard circuit. I have been able to positively identify all the chips except for the TO-220 devices at top right (one heatsinked, one bare) which are presumed to be voltage regulators, perhaps LM7805 or similar.

The DIP packages are typical CMOS chips that should be readily available from the usual suppliers.

TS556   Dual Timer
74HC123AN  Dual monostable multivibrator
74AC74P  Dual D-type Flip-Flop
74AC14PC   Hex Schmitt Trigger Inverter
TS372   Dual Comparator

I'm reposting Gotoluc's scopeshot along with the Gunderson scopeshot. As you can see Luc's shot is virtually identical to the "input" traces on Gunderson's shot.

And he achieved it with a much simpler circuit (but using a FG for the clock instead of making an oscillator out of logic chips.)

Now, I'd like to see what Luc can get for an output!

Thats why I was so impressed with Luc's waveform as soon as he showed it!!!
I agree!  Luc needs to rectify that output during the resting period.  It does appear
that GG's short pulse enhances the output period.
