That's a nice design and a step in the right direction.
Pls write some more info about the DC-DC connection transformers,  e.g. what is the capacitance between their primary and secondary windings?  Are they regulated?  Power, switching frequency, etc...

I am afraid you design will be lost on most people here, because it looks complex and expensive ...despite that it solves most FET driving problems and even saves money on burned up FETs in the long run and allows to do fast (μs) bidirectional solid state relays ...and the general versatility of the thing!
If it had drain overcurrent protection included, then only drain overvoltage and dv/dt could kill the FETs.


P.S.
Were you ever tempted to do gate charge recovery or HV gate pulse preemphasis?

Good day Verpies

About the Isolated dc-dc SMPS....  I designed the PCB to use the standard footprint ( for the Iso-SMPSs) to accommodate any brand of Iso-SMPS which incorporates the SIP style layout.

I chose (for economic reasons) the ND brand (Chinese made) Iso-dc-dc SMPS.  For the pcb in the photo, which will switch an Infineon FF150R12KS4_B2 IGBT 'Brick' which is a Short Tail, High speed -bridge configuration- IGBT module, I opted for an adjustable voltage range of +15,-5; Using only a -5volt (instead of the standard -8 or -10volt) reduces the overall power dissipation of the AVAGO opto.  (right now it is engineered to the limit of the AVAGO opto).

So, this pcb uses two pieces *12V to dual output 9V isolation 6kv - G1209S-2W unregulated SMPS*. and
two pieces  *6KV dc-dc unregulated single output 5v to 5v 2w SMPS*. One pair for each of the two AVAGO optos.

The dual 9volt output unregulated supplies allowed me to configure the design so the +9 & -9volt on the output are cumulative and float above Ve; Ve=0volt; which gives me a maximum of 18-20 volts above the Ve.  Since the Iso dc-dc supplies are non-regulated, I only have to adjust the Vcc, (input voltage to pcb) within a range of 10.8-13.2 volts to get a variable 14-20volt output @ the Iso dc-dc SMPS for the positive fraction of the Gate drive voltage.

The pcb also has on-board a small adjustable Buck Converter which is used to step down the Vcc (which is variable as stated above) to an adjustable range of 4-7volts.  This is fed into the input of the two pieces  *6KV dc-dc unregulated single output 5v to 5v 2w SMPS*.  Since they are likewise un-regulated, the output is between 4. and 7.volts, but these are connected below Ve accordingly to float the negative voltage (Vee) in relation to Ve.  So the negative voltage is adjustable from -4 to -7 volts.

The switching speed of the ND- iso dc-dc smps is between 70-100Khz depending on the model chosen.
The isolation capacitance is also model dependant, but for the dual output design the spec sheet says:
Isolation Capacitance Input-output, 100KHz/0.1V -- 5 -- pF...............

Unfortunately, the AVAGO  ACPL-K33T-060E do NOT integrate Desaturation protection nor drain overcurrent protection functionality, only UVLO, which is better than nothing.  I opted for the AVAGO  ACPL-K33T-060E optos at the time, because they were one of the first dedicated optos (15-30 volts range) made for use with SiC mosfets, and I originally intended to use SiC Fets with two of these pcbs (parametric resonance, ie; switching capacitances via microcontroller algorithm & zero voltage-crossing detector).  I would now look seriously at the Si. Labs line of RF iso-drivers.......

This Iso-pcb driver board can be used with any type of Clamping protections,  regenerative or dissipative.
This only depends on how you want to configure any additional reset windings, etc. in your XFRMR, paired inductors and so on.

The nice part is that your small signal logic is *isolated* and protected and your FETs should be a little more immune to the R.F. (guess that last part really depends on proper bridge (mosfet) layout on the power side).


"P.S.
Were you ever tempted to do gate charge recovery or HV gate pulse preemphasis? "

Considering that this pcb is just about 1/2 size of a pack of cigarettes, It might be hard to fit more functionality on board. At any frequency the pcb is capable of, dc to +1Mhz, the traces are of sufficiently short length that all transmission lines (traces) would be considered 'short transmission lines' or much less than 1/4 wavelength long of the operating freq.  So the effect on the propagation time delay would not be significant on these relatively slow signals.
I haven't seen much distortion in the signal, but than again I do not have a running kapanadze device to test it completely yet.

I would be interested in your idea of HV gate pulse preemphasis, it you have any literature you can recommend.

Actually after thinking about it for a while now, I am tempted to use a DRSSTC direct-feedback controller and a H-bridge via GDTs to drive the *yoke* primary windings in this device. Damn things are bullet proof and I know from experience that they can deal with the High level of RF. without distorting the waveform. 

take care, peace

  A win?  No, just an inverter, not self running.
  Until he can disconnect the battery and it continues running, there's nothing unconventional or special there.

Greatings to everbody
Hi Nick ,  hope everthing is nice with you .

To you seems nothing just a inverter what Ígor show , but you should think without " amplification "  in circuit how would possible feedback some part of "excess" power to feedback the main circuit ?
Without that aspect is Impossible reach to a feedback circuit.
Other aspect is the eficiencie of output . Most of outputs on this circuit i  see in forum , show a low eficiencie in output rounding 60% of total main input power source ... That seems something important to give some atention  first, until start think in running the system on own feedback.
Só clearly the subject that Ígor show is important and should be considered even knowing that is hard make precise  measures even with right measurement tools .

Hope a nice weekend to everbody

Electrical system efficiencies are measured in terms of energy in joules, not power in watts.

Jewels, oh what a treasure! where did you dig that up from ?
And you still haven't figured out where the energy is coming from, Have you ?

Have you ever played with a spark gap ? what's so special with it ?
What about girls in your family did they play with skipping ropes ? now whats so special about them ?

Your free lunch could be round the corner, or not as the case might be.
Never mind have fun resighting your man made laws. Ever thought you have been lied to all your life about everything ?

Electrical system efficiencies are measured in terms of energy in joules (watts x seconds), not straight I/O power ratios in watts. The time element is important.

Thanks by your observation , and that is true if we want to go deeple , but watts sure is enougth to ilustrate how could be the rácio of input vs output , do you agree ?
I think what i try explain is clear to most understand no need to complicate.
Im judge just in power of input  power module and the output provided in output in bulbs just that.
In a power source like most people  use should be possible teoricaly extract about t 360w (24v X15A) on the output if the conversion is near unity , and is not what happens . Is not logical that output Stay close  near unity 1 to achive the best eficiencie , when people are search by a "free energy" systems ? This what i mean .


Thanks

Yes Nelson nice to see you here again Nelson, If anyone here decided to do some homework there is plenty of documents telling you the theory on how the device works and many others, Only look.

Hi AG,
For sure you have right about that ,is only read  because information are available , but aplly that information  most of time is other story , because even small details make huge diference . So just read it will not enougth for sure to understand how to apply in practice need to sometimes have some luck and persistent .

Have a nice day

    Nelson:
   The reason that I said that it's only an inverter, is because once he feeds back some of the output back to the input, and shows it possibly self running, and hopefully not just on a tiny bulb like he is using, there can be possible meter measurement errors.
   His input source is a 12v, 7ah battery. His output is only lighting a small bulb. There is plenty of room for error.
   
   I have never seen neither Akula, Ruslan, nor anyone else showing "more out than in", ever.  Is that really a prerequisite for self running? I don't know, but I'm trying to look for a cause and effect to these devices. And after my over 3000 posts on this subject I'm still looking into it.
   NAR and NMR may also be a possible cause for the same or similar "amplification effect" from these devices, or maybe not, but, it's also on my plate to analyze if possible at this time.  It may involve the same effect, but, not due to nuclear decay of the fuel materials source, but to something else instead, such as Earth's magnetic resonant effects, as the gain medium.
 
   I've also been trying to raise my output voltage, as most of us are only showing a very low efficiency inverter, which is not leading to self running. So, I'm now converting the outputs to DC, which may be a step in the right direction. Or maybe not. However, I am working on finishing up another new full bridge rectifier, that will go on the output side to the bulbs. As that is what it may take to raise the voltage at the output, (possibly at the expense of the existing amperage). So, that I can see if that helps, or not.

   There seems to be many different ways to obtain a self running device, many different schematics to study, also. It can all get very confusing. 
   My system is built somewhat like what Igor is showing, using a similar ZVS magnetic circuit, and a simple Kacher for Hv circuit.
But, I'm using a Tv yoke instead of the flyback core for the magnetic circuit transformer. I had previously also used the flyback core, on Geo's type of MRG tests, which was also based on the ZVS circuit like Igor is now showing.
   Igor has not shown a self running device to date, nor have I. Hopefully that will change in the near future.

   If there is anything new and exciting from your experiments on these self running systems, we would love to hear about it...
You can also PM me if you prefer.

Hi Nick ,
Yes ! Is that my point ! Until know the system that people are working at present moment is even close a full effiencie inverter like you told . Way should not be a requesite show more out than in ? Is not what everbody search ? To me seems logical .
Some months ago i refer a lot o times that effects that are showed by ruslan and akula could be reproduced in other ways . That is way most of anounced "free energy" devices most of time have some simillarity between them.
All the roads goes to Rome . And several ways could be used to achive the goal . If you think well every that devices have something in common in their work operation  is not curious ? I know that you and lot of people already think in that .

A self runner device is not a free energy device , but a more convenient way to convert and produce currents in a self sustaining oscillation circuit where the output is capable to produce more work (W) and provide the enought power to sustaining the circuit until "main power input" is depeleted or interrupted.
And in a system like that  you could find at first eye that have several Stages in that system  not only one circuit.
So is important study many diferent aspects of all Stages envolved.
Igor show important aspects but must be understood  only that , and should not be desconsidered because in my opinion is important and easy to understand what he try show.

About news nothing new only some small improvements and some changes in hv stage ; im learn everday how to improve many aspects of system like you and other guys . I retain one important thing  :  we should have more precaution with what we dont see then what we see and think is aparently more dangerous .
Take care .


Hope see progress updates very soon  by everbody envolved

Cheers
