Akula0083 30 Watt Self Running Generator.

[Grumage]

Dear Grum,

The frequency limits for the RT and CT components in the schematic (1K+10K potentiometer and 3.3nF cap) are 363KHz ( Pot at 0 ohms) and 33.06KHz ( pot at 10K). Using this information, and the table I just posted, I would say that the transformer core (with the gap) has an AL less than 400. As the dimension of the gap will influence the final AL of the core, you can always adjust the gap to fine tune particular core you have.

Cheers,

Dear Black_Bird.

Many thanks for that info. The cores I have obtained have an AL Value = 4100. I hope they are not too large ??

Cheers Grum.

In this 100 year old patent Benitez uses an electrostatic generator to energize one plate of a HV capacitor.
He then alternately pumps the ground via a Tesla controller/interrupter switch to energize the other plate of the capacitor.
He intercepts the ground surge with a 1:1 trafo.
He then diodes the output back into the input.
The device is self running.
We can do all this electronically.
It took me 2 weeks to understand the patent.
The patent was granted.
Those with working Tesla coils, Slayers, Karchers, etc should think of their devices as electrostatic generators
and modify their circuits accordingly.

I just made a simple HV electrostatic generator by using 3 basic parts.

1. 12 V 7Ah Accumulator.
2.  A cheap 18 Watt CFL inverter circuit that lights a CFL with a 12 V DC input.
3. A flyback trafo. Wired the inverter output to flyback input.

The HV and ground output wires light the CFLs wirelessly and generates some wonderful blue sparks streamers. The spark gap max is 1 cm.

I guess the output is above 10kv.


A.king21 can you suggest a simple circuit to replicate Benitez patent with this device.

Many thanks ahead of time.

Best,

Good Day All:
Just wanted to say thanks for starting this post:
I have been following the work of AKULA since last year:

OK, just my two cents worth:

Hi Grum,

With AL=4100, and no gap, primary inductance will be around 920uH. At 33KHz, minimum frequency of TL494 in this circuit, the maximum current during conduction will be around 177 mA, which is low to get the desired 30W output. when you introduce the gap, AL will reduce and consequently the value of primary inductance will also reduce. You will need some experimenting with the gap value to get the desired output current.

Cheers,
