posts from stocker_x1 on www.energeticforum.com and www.energy.team-talk.net

a little side note, he buy a few parts on ebay :)

Thank u very much!!!!!!!!!!!  :)

But maybe we should move this discussion to another thread, as this was meant for the 30W akula device i guess  ;)

Dear Black_Bird.

No load, just the output rectified and put back to the input. Please correct me if I am wrong, if I have read the circuit correctly the load is applied off the primary of the transformer. This leaves the secondary to help with recuperation ??

Cheers Grum.
Grum - What schematic are you working from?
Can you post a copy of it?

Dear All.

I will try to answer some questions.

Dear lost_bro.

Not quite with you on that one ?? The frequency of 4.91 KHz seems to be where the ring is best. I used the cursor to measure the start of the pulse and the start of the next one. As you can see the duty cycle is very small!! Please elaborate !!  :)

Cheers Grum.

Good day Grum:

OK please see attached pic:

The frequency of the ringing refers to the actual cycles (frequency) of the small component of the waveform which I have circled in RED.

When you ping a tuned circuit with just ONE pulse, ( single pulse generator for example) you will generate a response in time with the LC (LCR) constant of that circuit.

Long story short:  the ringing of the faster (smaller) waveform within the larger (slower) 4.91Khz wave, is closer to the actual Resonant frequency of that system.

Measure the frequency of the small (faster) waveform and use that faster (higher ) frequency to pulse the system.

Let me know if I need to explain more.

Thanks, peace

It is right, but the load will influence in the amount of current that is fed back by the secondary. My question was about the ringing. I suppose that the ringing will vanish or reduce a lot when the load is in place.

Dear lost_bro.

Fully understood and thanks for the interpretation.  :)  Please find attached scope shot at the ring frequency.

Dear Black_Bird.

Yes you are correct in your assumptions that a load does indeed affect the ringing !!

Cheers Grum.

Addendum.  Silly me !! Ch1 input signal to L1. Ch2 output signal from L2 on to input of FWBR.  :)

The real truth here is you disrespect professional standards , health and safety , respect for the global science community , and offer nothing in the research as there is nothing you can offer! It is well known in circles that are looking with total dread of your approach .

You are playing with a fire you refuse to respect and there for we will respond in legal terms to your government not you !

Well that is embarrassing, you missed point in this forum...
People who are experimenting here know things about high voltage/high frequency and all related stuff so your posts are just going to dustbin.
Please post YOUR experiments or do not post at all.

Thank you.

Periodically we are going to refresh the front page and the schematic we are working to duplicate, to keep the forum on the rails.
No need to worry

On my phone but just had to reply.. Everyone please ignore nanobot He is a troll or shill... Many people play with this technology and it is not effecting their health..  The other option is to move to OUR where there are better mods

Hello Grum:
Thanks for posting the o-scope shot:

OK, are you using a square wave to drive L1 on the scope shot?

What are you using to generate the driving signal for L1.

I will only comment that the driving signal *should* be as clean as possible......

I don't see the square wave there at all, maybe I'm not seeing this correctly.

Take care, peace
lost_bro

EDIT  , another queston, since you are driving an inductive load, are you using a Freewheeling diode across the inductor/MOSFET? 

If not, that by itself will inject *a lot* of noise into the driving signal and quite possible fry the MOSFET.

Dear All.

"It takes all sorts to make a world" something my dear Grandmother often said to me when I was young !!

I feel there is a wealth of experience here at OU.Com, keep it coming !!

Best wishes and good luck to all, Grum.

Dear lost_bro.

I am driving the transformer with an older type of RM Cybernetics PWM's  this unit has now been superseded by a much more robust design !! However the new design has a current limit device which seems to alter the effects I am seeing. As to the transistor I have no idea at this moment!!

My duty cycle is very low probably much less than 10% . I am just hitting it with little pulses "ah la" Tesla style !!

I have attached the pdf that was available when the PWM was in production. You may then be able to have a better idea of how I am driving the transformer.

Cheers Grum.

Hello Grum

Thanks for sending a copy of the PWM manual.
OK:

Driving Inductive Loads (Motors, Solenoids, Transformers, Relays, Coils, etc)
 
The PWM-OCB has only basic protection against high voltage transients from inductive loads.
When driving inductive loads you should take extra measures (detailed below) to protect the
OCB from high voltage transients. This unit is not suitable for use with ignition coils. You
should use the other more advanced models such as the OCBI, or OCXI for such loads.
 
Place a fast diode such as a schottky diode in parallel with the load input terminals as close to
it as possible. If you are using a switch to reverse the direction of a motor, the diode should
be placed just before the switch, between the switch and the OCB. See figure 3.


Yes, that is from page 5 and they are referring to a Freewheeling diode. 
 That diode will help keep from heating up and destroying your MOSFET in the PWM.   Otherwise know as an Inductive Kickback diode, it makes a path for the *back*EMF to bypass the current when the inductor is off, as the current lags in an inductor.

**EDIT, maybe it is this same lagging current from L1 that we want to channel somewhere else for this purpose?

Wow now I'm not real sure.....

My duty cycle is very low probably much less than 10% . I am just hitting it with little pulses "ah la" Tesla style !!

If you hit with 50% duty cycle, will the MOSFET heat up?

take care, peace

So the actual schematic still hasnt the ground connection on the other side of the voltagedivider and the LED? Seems strange to me. Anyone tested if its working this way? Cant imagine that unless pin 16 of TL494 is able to provide a ground somehow... Or am i totally wrong? Maybe one of  the pros here like verpies or TK can have a look at this and give a statement?
