Yes Michael, Its Capacitive and Inductive Reactance.

I think also IMPEDANCE or the AC resistance that is produced at one frequency will vary with the amount of power running thru this coil? Am I right so far?

** No, The Power transfer Will Vary as the Frequency Changes.
Example: if the Inductive reactance was 100 ohms, As the Frequency Up, The Power Will Increase. And Visa Versa
The Higher the Frequency, Also the Smaller the transformer for a given power. This is Why a lot of switching supplys now operate at 100Khz to 1 Mhz.

Short on TIME TODAY And Tired. (Was Up at 4AM and only 3 hours sleep)

Quick Answers as BEST I CAN. Brain Not Awake Much.

#1 Where do I start on turns for primary or secondary.
** You Start by Knowing the Frequency and Power you want to Transfer.
** Than Determine an Inductive reactance that will allow that current to Flow at the Supply Voltage you have.
(NOTE Also: Since a PERFECT COIL Doesn't Exist, the Coil Has CAPACITANCE and Capacitive Reactance.)
** Basically Than Choose a Suitable Core and Wire Gauge and start on the Primary.
**** BUT HERE is Where the AL Value comes in. OR Trial and Error with an Inductance meter.
** There is Also the Type of Core to Decide. Torroid, E Core, Pot Core, and Many Other types. Some May Require Gapping, But Thats Another Subject.
THIS ALL GETS VERY COMPLICATED.

#2 How much resistance will the driver circuit take from my coils before burning up?
** Sorry Doesn't make sense.

#3 Because 3 frec's are being used all at one time, what would be a good core mix for such a broad range of operation.
** The Concern is More the Power. Typically a Fair-Rite Core, Material 77 Will Handle the Frequencys that Bob is using.
** Sorry CAN'T List All the manufacturers and there Equivalants. There are Hundreds of different Manufacturers.
** In My OPINION a Seperate transformer for EACH Frequency, Than Series the Outputs.

#4 Do design practices for driver circuits have a common value of resistance at the output stage and how could it's max SAFE value be determined??
** COMPLEX QUESTION, Depends on How you designed the Driver.
Most of whats on this Site is Just a MOSFET, acting as an "On/OFF Switch".
A SUITABLE FUSE will usually Protect it.

#5 Finally what kind of wire is best for these inductor/toroidal's or do many types of wire still work pretty good?
** For What your Doing Here, Just Ordinary Magnet Wire is fine.
(Enamel Transformer wire)

** THESE are Not Super High Frequencys, Nor are they Really Fast Rise Time Pulses.

Hope this Helps a Bit.......Gary

Chemelec, Great answers and you were right that one question didn't make much sense. I had just gotten up and wasn't percolating on all cylinders yet. No Mater.

Anyway I got my answer when you reminded me of the way MOSFET's work just being switches.

I wonder if Bob ever thought of your idea?

Thanks for the help

you arent gonna be able to take FULL advantage of this technology that way.

[kevinsatterfield]

thers so much information and so far Im the only one that i know of that sees the similarites in Bobs stuff and wat alot of the energy devises being studdied have in common.

That would be a conventional way of looking at things, just as combining frequencies into a common driver, This is fine for single/split phase operation, as in my older research. The limitations of that methodology caused me to rethink my approach. Single/split phase is like looking at this 2 dimensionally.

Try to picture this as an electromagnetic hologram, where the interference patterns between the 3 waveforms interact to fill in a more complex waveform pattern. Phase interactions within a single core are extremely important here, which is not going to happen with seperate frequencies in isolated cores.

The toroidal transformer is not just there to couple the power to the cell, it is an integral part of the overall power source.
