Hi ZPE,

Thanks for the tips. I'm looking around to see what is available now. Would you happen to know of any good ICs out there that would work for the voltage range I need?

God Bless,

Jason,

You're not likely to find any OTS chips that will handle anything higher than 10V or so, but that's no problem. In fact the way it is done is to use an attenuator stage, similar to how regular voltmeters work.

Build your own attenuator network, and if you are not too concerned about high precision, using 5% resistors will do the job.

If you want to measure the collector coil's power output as you sweep through your frequencies etc., then I would suggest you connect the coil output to a fairly heavy load of known value and of pure resistance (i.e. non-inductive). This way the output voltage is not likely to be very high in amplitude, and no attenuators or high voltage measurement necessary. All that you need do now is measure the voltage across this known load with a good RMS-DC converter, and with the known load resistance, you can calculate output power on the fly.

Or were you wanting to do something else?

I've created a simple simulation of moving fields generated by a 2 phase system.

It's something basic which is happening in AC motors, linear accelerators, etc..

Notice in the animation the RED and BLUE waves are STATIONARY  (x-axis is distance),  and the GREEN wave which is the summation of the two waves is  MOVING !!!

Hope you enjoy this, it might help somebody.

EM, thanks for the animation.

I suppose the same could be done with 3 phases.

Sure, 3 phases would give you the same moving field if phased just right (120deg apart I believe)

But I won't bother with that simulationÃ, 

I hope you guys can appreciate the insight Nicola Tesla had more then 100 years ago when there were no computers like we have today.Ã, Ã,  He envisioned this all in his head !!!Ã,  Ã,  What a visionary !!Ã,  Ha HaÃ,  Ã, 


Now,Ã,  I believe people need to grasp such basic concepts in order to figure out the SM toroidal power unit (TPU).Ã,  He talks about rotation etc, so I wouldn't doubt that he uses a simular concept albeit the field directions can be different, the phenomena could be electric/or maybe just magnetic, etc..Ã,  Lots of variables to play with.
