wow nice! no counter emf!  keep up the good work tinman!

Tinman,

Sorry to hear you have the flu.

From your scope shots, it is obvious the inner secondary presents way less energy content at 100Khz than the outer secondary, which appears to be peaking around 100KHz.

To further understand why the inner appears so heavily damped under those operating conditions, consider the following:

What do the secondary waveforms look like unloaded (individually and simultaneously)? 

What does your primary drive waveform look like?

A sine sweep from 10KHz to 400KHz, with and without the 100R load, will let you see response peaks and roll-offs and possibly identify the SRF's of the two secondaries as well.

On another note, when you say that you are driving with your SG, what exactly does that mean?  Would not using your really cool FG (buffered if necessary), with complete control of the drive waveform's frequency content (i.e., period, duty cycle, and rise/fall times) be more revealing and useful to you?

Only spent 30 minutes in the workshop today,as the flu is kicking my ass ATM.

Take a break for a bit Brad.  You have posted plenty of information for others to step up to the plate and confirm your findings.

Anyway,i carried out the following test today...

Whats your thought's on this?.

Looks to me like a simple push-pull oscillator is plenty capable of driving this device.  Verpies posted a circuit on another thread that will properly handle the kickback on the primary.  Seems to me this would be a great starting point for higher power experimentation.

Have only recently looked at this thread.  It is clear from Brad's measurements that the flux through the inner secondary is about twice that through the outer secondary.  To see how this could come about you need to analyse the thing in the magnetic domain.  In this domain flux Phi acts like current, mmf U acts like voltage and reluctance acts like resistance.  Coils connected to loads act like magnetic inductances obeying U =-L*dPhi/dt.  Here is the magnetic domain circuit.  For inner Phi to be twice the total Phi it is clear that the outer Phi actually flows the other way, and has a value about half the inner Phi.  How can you get flux flowing the wrong way?  Well it must come from the load current creating the mmf that is across the inner magnetic inductor and that drives flux around the closed magnetic path that is inner in parallel with outer.  That in itself is something of a relevation and is hitherto an unknown effect.  But Brad's measurments seem to imply that very thing.

@Smudge

When you say:

For inner Phi to be twice the total Phi it is clear that the outer Phi actually flows the other way, and has a value about half the inner Phi.

Essentially all you are saying is that the Outer Core is the Exciter for the Inner Secondary, when carrying Current which then in turn creates its own Magnetic Field which in turn has an Isolated Magnetic Path from that of the Primary Magnetic Field...

One could say this has essentially circumvented Lenz's Law, but to be correct it has only isolated Lenz's Law from the Primary Magnetic Field as we need Lenz's Law, the (-) sign in the Equation for Induction: emf = -N dPhi/dt, for this to work, and thus as a result the Electric Field Intensity is now twice that of what would be conventionally seen!

Well, it seems to me that Free Energy Gain is Ensuing!

Good Work Tinman! Hope the Flu passes quick Mate!
