Tank Circuit Experiments with opposing coils

i spent a lot of time reading through the information on this website and decided to do this opposing-coil-thing on my tank circuits.

first i want to show you the circuit that i am working on.

i made a drawing that you can see what is going on there..

the first apparatus looks like this..

it works brillant and i can get a lot of these LED's working with less input from DC source.

then i found this forum and i am still trying to understand deeper what you have on the table. so i tried a new coil based on the information i understand.

this is how the coil looks like...

i made the L1 on the outside and L2/L3 are on the inside.

the circuit that i build is this one..

the results are good - i will get professional measurement equipment in a few weeks to get an idea on how much energy i can get out of this thing.

at the moment i have 1,2kV on L1 at resonance condition.

thank you for your hard work!


some more pictures..

Hey Baerndorfer, Excelent work, and good documentation. Thanks for sharing.It looks similar to a Don Smith's design. Vidura.

Hello Baerndorfer,

Thanks for all the great detail. I did have a question regarding your setup. The device you call the H-bridge has only 1 out - but I would have expected an H bridge to have 2 outs. Can you elaborate a little bit more on your H-bridge circuitry?

this is the h-bridge circuit that i use at the moment..

Hey Baerndorfer, The schematic show's a half bridge configuration, that is why only one output is there, the H bridge or full bridge consists of four Switches. It seems you are a skilled builder, your setup looking professional. Thanks, Vidura.

Awesome, thanks. I use mosfet drivers that have the same configuration (half bridge) in a similar manner. It is a very interesting line of research. Thank you for sharing it in such great detail.

i like to post some drawings here that help me in better understanding this magnetic thing..

just finished a new switching device. hope that the cable ties can handle higher temperatures...

This time i use an IRS2304 gate driver IC. Frequency and Duty Cycle is adjustable with the 4 buttons. All relevant info is on the OLED.

still many things to do..

The great Nikola Tesla:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago go by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
