Quick info: pulse generated is almost not loaded down (no current draw), but a 450V resonant wave is generated from this pulse.
I have a toroid with 2x 150cm wire wound in bucking mode (counter wound so the magnetic field is opposite).
The IGBT puts 12Vdc on the coils, and switches this, at the resonant frequency of the second bifilar coil.
when the power is on the coils, the magnetic fields "cancel out" but, the energy is still there. I see it as if the ether is being compressed.
When the switch is opened the ether decompresses quickly. giving a bemf pulse.
That pulse is taken at the switched side from the bucking coil into the outside rim connection of a phi ratio hole speaker wire side by side Bifilar coil. the inside rim connection is left open
The bucking coils, give a inductance of 0,06mH that is very low... This is a perfect match for power transfer into a bifilar coil (low impedance).
The resonant coil is a similar coil, placed on top. the center is grounded, and the outside rim is probed, showing a 450V pp @ 499kHz.
It takes some power to let the field buck in the coils. But the pulse that comes out, almost isnt influenced by the bifilar coil. The 105V pulse drops to 95V when both coils are in position.
I wonder how many coils I could put into their resonant frequency, with that b'emf pulse from the bucking coils.
I have to test how much energy is needed to make that pulse. I guess its a bit more than I would like, because the coils are bucking. Its like putting two magnets that are rejecting each other, are pushing together (in the toroid).
also... I think the material of the toroid isn't optimized for this. I need to wind a better toroid core.
Using a 12V battery as power source for the igbt/bucking
and the rectified sine into a cap, via a small load (led light) back into the battery, would be... wonderful.
Even the left over Bemf pulse could be rectified, buffered in a (low esr) capacitor, and put back into the battery.
Sorry For The Long Story... I understand this will be much more interesting with a closed loop result (charging battery and bright LED). :yodel:
indeed, pictures will follow. my phone is charging, and I need a recharge too.
