lol Im scared of belts and pulleys they have not done well for automotive alternator except to keep the engine business alive.

Hi,

Which interrupter? Could you clarify that idea? A picture or link will be nice to see it

Regards

hi...    hanon
more about   interrupter    google    "  ruhmkorff coil " . 

I have performed two changes:
First, I replace the 300T coil with an 800T. And,
Second (the most important) is the replacement of the 0.6 mm air gap spacers with 0.1 mm. The performance improved dramatically. I have the primary and secondary iron cores practically touching each other but there is not electrical continuity (isolated) for very small air gaps.
I am sure that there is a way of adjusting the reluctances of the air gaps. For example, the standard transformers have the 'E' and 'I' electrically isolated but the reluctance of the magnetic path is made very low by overlapping the 'E' and the 'I'. What I want to say is that the reluctance of the air gaps can be adjusted lower by partially overlapping the 'C' and the 'I' of the Figuera's devices. The electrical isolation should be maintained to get the required air gap reluctances. By doing the latter, it might be possible to use secondary coils with lower number of turns and high current output. I have this task as an item in my "to do" list.
I am still using the step driver, which is not good because it behaves as a current source instead of a voltage. I am in the process of replacing the driver for a more suitable power supply.

Look at the tables of the attached document showing the open and short tests results for the 400T and 600T primary taps.
The output power calculated above is based on a Thevenin circuit. The power output is the power absorbed by the internal resistance. As a conservative value, assume 30% error to account for measurement issues.

Do not feel disappointed if you do not see huge power gains (KW). This is a device with a technology that we have just started to experiment with. It will take some time to get the feeling for its design and extra its full potential.


According to the news, Mr. Figuera was able to make very powerful MEGs. And, I am confident that we will be able to replicate his apparatus.


Being an engineer and having more than 30 years of experience in the field, this moment is a turning point in my professional life. I would have never expected to see a device that can output more than what is being input. At least, that what is taught at all engineering schools.

Please, note how the results from tests #11 and #12 do not practically change. This is because of the step driver saturation. When using the 600T and 750T taps, the step driver cannot increase the voltage any further to maintain a current preset (Ipeak). The voltage limit for this step driver is 50 Volts.
