maybe the core material of the toroid cannot operate past a certain point because of the rise and fall time in between pulse is kinda like staying in a magnetised or saturated  state past  5khz   is it an iron core you might want to go to a laminated style

their is a good book called transformer and inductor design handbook  you can buy it of amazon. books for 50 bucks used

Hi all,

I am having trouble with the following part of the JN and Stan Meyer schematics,
The thing is how to pulse a transformer.
We all see the FET pulsing one of the 2 coils of the trafo.
What ever i try, the maximum frequency acceptable for the trafo is 5khz...
At that part , the signal is getting worse and worse.
I wanna go up to 300khz......
I have an oscillator that can reach this frequency
I have a FET that do the job.
BUT my toroid trafo is keeping me from getting there. I need HV at 300khz!
All  suggestions are appriciated!

In the drawing of the insulated tubes that hydrogenmask posted it shows a resistor to ground(or maybe the cathode tube).  The transformer secondary is going to need at a little current flow to have a pulsed output or else it will "saturate"(I think).  It may be the bifilar transformer is providing a capacitve load on the secondary of the step up transformer. 

You could start trying different values of resistors loading the secondary of the transformer(after the diode) and see what happens to the pulse shape of the output.  I would start with 100Kohm and see what happens. You could try a potentiometer, but I think it would probably arc at the potentials we want.

I have also examined the D14.pdf, Dave included pictures of the outer tubes and how they are wired. However, he was very careful not to show any pictures of the inner tubes.

I think the information we need to replicate Myers's cell is being withheld.

You most likely have too much inductance in the primary.  At 300khz the high inductance of your coil will not allow it to build up a field. Reduce the number of turns in the primary and you should be able to use a higher frequency.    At 300Khz,  my guess is that you will need only about 10 turns to get an inductance value of about  100uh.    Most SMPS's  that operate in that frequency range use inductance values from around 10uf to 100uf depending upon the duty cycle.

Document Type and Number:United States Patent 4613739
Inventors:Richards, Paul L. (St. Joseph Township, Berrien County, MI)
Abstract:A microwave oven control utilizing a microcomputer. The control permits changing or adding to previously inputted parameters without requiring the cancellation of the entire program and without affecting the progression of other cycles of the program. In the illustrated embodiment, the control provides for facilitated initial input and changing of parameters, such as time, temperature, power; and the like, relative to different commands or functions inputted by suitable touch pads provided in a control panel for actuation by the user.

Outlaw,
This is filed in the US Patent Office under that #
Do you know what country it's filed in?
