Alan
Seems you have done a lot of work here
And sharing openly!!


Will be sure to pass along to the open source community/builders !


With gratitude

I have to admit the Reddit host is annoying ( can’t read on phone unless I sign up for app ( pc is ok), however
Your contribution is intriguing!

Alan,

As is pointed out in the article accompanying the simulation, with a K factor or coupling of 1,  there is no separation of the the L1 and L2 windings.  Therefore there is zero buck inductance and the coils for all practical purposes are one.  If the coils occupy the same space at the same time, the energies shown in the sim perfectly cancel with no remaining source to draw extra energy from. 

As we know, a perfect coupling or K factor of 1 is impossible to achieve in the practical word apart from a simulation.  A tightly wound bifilar coil would typically have a K factor of .94-.96.

Regards,
Pm

Here's an old POC(will update with better schematic,  my L3 connection is backwards in drawing) I made and came back to after getting a better understanding of circuits, impedance,  and the reaction of my coils, etc... still have a ways to go. But this setup is very simple, if anyone can give me a better way of checking my results(proper measurements etc.) or if I got it wrong,  point me in the right direction. I've learned alot following Chris's work, and direct hints(tho most are looking for him to make it work for them or explicit explanations of what to do in each case. Tho he's already gave them). There is still ALOT I haven't looked at that could possibly improve results(check L1 for resonance, changing loads, etc...) Any tips appreciated, will update with coil specs soon.

Updated pic, L3 still backwards, but pic of core above is correct. I was shooting for the 3.5watts the bulb is rated for, and used Don Smith's formula (cps=Volt amps * C)-think that's right- to get frequency needed. Tho, may not be applicable but actual frequency is about equal to: sqrt(((3.5watt/400pF)/20))) = 20.916khz. Random typing in calc. I'm sure my measurements are off, but it's a good start. Last pic is with probes behind diodes to see waveforms.

Other interesting waveforms, showing 180° phase shifts along with sawtooth output.

AU,

Could you please resize your attachments to fit the typical screen size.  Usually 800 pixels in width does just fine.

It is extremely difficult to follow along!

Same setup using half bridge tho, you see the current rise in 10% and work done the other 90.

You need to take the duty cycle and means into account when  calculating average power, peak powers don't compare.

Duty cycle is about 8%, mean voltage = 60v, mean current = 36mA for last pic, duty is 10% and mean values shown on scope.  Unless im missing something?

15v x 0.06a = 0.9w only for continuous DC. At Tdc = 10%, 10% of the period is 0.9w, 90% is 0w, 100% period is 0.09w average (Ppeak x Tdc/Tperiod), because you want to know power over continuous time, not per period or peak.
