Good day MagPwr.

I will give you credit on the observation regarding the Chinese D.S. replication by 'Salty Citrus';  ie; the 3825 IC chip being used  to generate a nano-pulse by using sub-prime voltage levels @ Vcc.  Good observation :D

So........ have attached a diagram of the Akula double TL-494 circuit (Miller clamped).  This was NOT the circuit that we experimented with.  We experimented with the Single TL-494 30watt circuit (see attached) that used an EE-ETD49 core, not the Flyback core you speak of.  The Flyback core was used in the double TL-494 circuit.

Being that I have not experimented with the circuit you are speaking of, I will comment from observation of the attached schematic:  I see that the bottom MOSFET has an *Active Miller Clamp* in the form of a PNP transistor. This type of application of a PNP transistor allows for a faster discharging of the MOSFET gate-source internal capacitance at turn-off (Signal low).  It is kind of odd that only ONE of the TWO MOSFETs have this clamp addition... Unless it is for a reason ;)

Why is that?  Along the lines of your suggestion that one of the two Mosfets be switched ON/OFF very abruptly in order to generate a super short switching time (interrupter), It makes sense that the lower MOSFET is the FET that is *fast Switched* and that PNP clamping transistor supports a much faster *turn-off* speed than the upper MOSFET without the clamp. So you could be on the right track. Does this second fast switched TL-494 also use a marginal VCC to instigate the fast switching?

I would like to find the possible mechanism(interrupter) for the attached single TL-494 30watt AKULA schematic. We spent much time on that circuit to no avail.
Guess we could of used your help with that one MagPwr.

take care, peace

EDIT: sorry to going OFF thread.........

hi lost_bro,

It seems i have never looked into that circuit before.
I think there is a video for this device and i have never saved that link before.

It would be nice if you can pass me the old video link somewhere from youtube for me to look into.

I leave it to you if you want to private message me or post it in the other Akula device topic created previously.
This is one of the I/C which was spotted on Akula device.

Take note of timezone over here is about 12hr ahead of USA.

Since you do not have working device that test is inconclusive.

Your device is clearly sensitive to magnetic fields.  The question is why?  Is it a simple permeability modulation of the Yoke's core or something else?  The former will manifest as the classical BH curve distortion.

If you can make the tuning suboptimal without the magnet and optimal with the magnet, then it is just a matter of shifting the optimal point as there are internal magnetic fields to account for, besides the field of the PM.

The first question is what is the magnet influencing? I assume the answer is: "the Yoke's core"
The second question is how is it influencing it?  How sensitive is the frequency to the? magnet's orientation and proximity?

Note how sensitive the water magnetometer is to external magnetic fields.

  Verpies:  Ok, thanks for your reply.
  Are you saying that to study the affects of NAR or NMR the devices has to be self running, or what exactly? As my system is running, but not self running, as I haven't even tried to do that yet.
  First question:  The magnet is affecting the magnetic domains of the yoke core, and that is also affecting whole system, not just the yoke, as are the HV/HF interactions.
  Second question: The frequency response to the magnet is very sensitive.  The frequency can be altered, and the output voltage and wave forms as well. Even placing the magnet a couple of inches away from the yoke. Magnet orientation is also affecting the wave forms, and it's somewhat tricky finding the best location and orientation of the magnet, or magnets. Adding more magnetite magnets also can produce an even higher output, than just using a single magnet.
  I can't get the same output without the use of the magnet on the yoke core, as I can with it. No matter what I do to tune the device. However, sometimes neither the magnet nor adding ferrite into the grenade former tube will produce a better output.
So, it seams to matter how the system set up, and where its normal running frequencies are at, if these things will add to the output, or not.  In my case they do help, but that may not be the case with other devices.

Hoppy, its funny how we talk about yoke fet interrupted over a year ago and then someone says no one notices.
Finally confirmed on the bench that a 50/50 drive on the yoke is far less efficient than about 43% duty cycle drive making sure to give a few microseconds of pause between each push and pull.  Its a dramatic increase and is the same effect that i have seen from the tesla nano second pulse, that does the interrupting the yoke fet in mid drive. As you back away from a 50 50 drive the output increases while input decreases. Just simply giving time for the magnetic field to begin to collapse on its own rather than drive it immediately nothing special. Arduino micro controller can indeed do the drive signals if you use the direct port control of the outputs and use its internal timer to maintain exact frequency and timing. I am using Yoke drive only and seeing a dramatic effect of increased output while at the same time less input.  Arduino can be cheap programmable signal generator for $5.00. I am setting up 3rd output to drive tesla nano second driver later on after this is fully explored. Also plan to experiment with one shorter signal than the other. for example short push and long pull. Probably will find nothing but easy to do. Also noticed a large magnet 4x6x1 ferrite about 2 inches away from the yoke increases output slightly any closer and it decreases output.
Program:
  Timer1.initialize(108);                        //  preseting freqency at startup repeats every 108 microseconds
  Timer1.attachInterrupt(yokedrive);   // yokedrive sequence
// This interrupt will turn on and off FET yoke drive. A driver ic located in front of each fet to sharpen the signals.

void yokedrive(void)
{
PORTD |= 1<<5;      // sets output bit 2 high DRIVE FET (push) on
delayMicroseconds (35);
PORTD &= ~(1<<5);   // sets output bit 2 low OFF
delayMicroseconds (18);
PORTB |= 1<<2;      // sets output bit 2 high DRIVE FET (pull) off
delayMicroseconds (35);
PORTB &= ~(1<<2);   // sets output bit 2 low OFF
  }                 //this is natural pause here of about 18 microseconds until next yoke drive sequence.

How this active miller clamp can be extended for two fets connected together to make bi-directional switch, which can work also wit AC signal ? I see the important to clamp signal immediately and in both directions, but the DC SSR's are slow.

Good day Bat1Robin2

Nice, Interrupt Service Routine with direct PORT manipulation, much faster response than coding via the  Arduino GUI.

Please keep us updated as to your progress......  I have had problems before with  RF interference when driving logic is from a Micro controller source.   Good shielding techniques, ie; Arduino inside a Grounded Aluminum enclosure & all signal wires bundled/twisted and as short as possible seems to do the trick.
Try a ferrite bead on the Positive of the bundled pair feedback wires, close the the microcontroller board.

thanks for sharing.
take care, peace
