Akula0083 30 Watt Self Running Generator.

I think shield plate is used as in other DC-DC converters to eliminate EMI. Maybe by using not closed one it acts also differently who knows ? I bet you heard about radio waves collector with antenna germanium diodes and capacitors ?

I guess the short answer is related to the actual problem>    If it is related to saturation of the core, it is directly related to the core permeability, core size and winding ratios .....  and the core permeablility can be changed by changing the core material.

All the ETD cores that I have here now are PC40 TDK material.
I do not know what Grumage used for the core material, I would have to pull out the charts to see how that all works out...

take care, peace

Dear lost_bro.

I did post the core material I was using on page one. Here is the link to that post.      http://www.overunity.com/14378/akula0083-30-watt-self-running-generator/msg391374/#msg391374

Wow, page 12 already !! I hope it doesn't turn into another Kapanadze thread !!

I would like to ask politely that the members of this forum who are not seriously interested in pursuing this Akula device to refrain from posting their concerns about the validity or viability of this device.
Let those of us Don Quixote's who wish to chase windmills, get on with the task !! You can say, I told you so !! When the time comes !! 

Back to business.

Could one of the more experienced electronics guys explain, in "Layman's" terms, what Avalanche mode means ?? I myself have only a basic knowledge of electronics, this would help me and I am sure a few others as well !!

Cheers Grum.

I agree that fully avalanche rated mosfet is the key. I don't completly understood this avalanche mode but I feel it may be explained as a breakdown of p-n junction like that occuring in diodes when overvoltage happen. In most cases it causes damage to diode but certain classes are immune to it (zener diodes) . Avalanche mosfets IMHO may be classified as mosfets with zener diode behaviour.
Just my opinion. The main factor is the real avalanche operation is differrently maintained by different mosfet producers , as afar as I know the best would be fully avalanche rated mosfet.

Dave , I read your post. Really inspiring but people like Zilano and kdkinin etc just vanish from public forums once they have a working device. Humans never share their secrets because of greed and ego. Many examples galore. People join forums, learn, make and vanish, they never share their success. Others turn to fakery to gain importance. Human logic is stupid. Even dogs are better.

Best,

Zilano NEVER had a working device.  She just copy & paste information.
She NEVER showed a pic or video or measurements.

Dear All.

I have some good news to report!! 

Using the T-1000 winding configuration posted here.   http://www.overunity.com/14378/akula0083-30-watt-self-running-generator/msg391561/#msg391561

I have been able to create parallel ringing between pulses. Using between 5 and 10% duty on my PWM, frequency set at 5 KHz and very careful gap adjustment you can alter the pulse from a total ringdown to a linear ring!!

What is even better, no transistor warming!!  More tests to follow !!

Cheers Grum.
