Hi,
Merry Christmas!
Here is what I have tried, am I headed in the right direction?
I think the most important thing in this experiment, is set up like this, when I disconnect the Bucking Coil Diode, the light goes to about 1/10 brightness.
I just built this with stuff laying around.
Things to try next for improvement:
1) My signal generator won't put out a low duty cycle, so I just built one up real quick from a TL494, which seems to not be able to go to the lower frequencies. Right now the scope shots are at .2ms/div, About 1kHz. I would like to try lower frequencies.
2) Try different loads, maybe lamps in series to get the voltage up, with a higher resistance load.
3) Try Zener diodes, or Zener diode and MOSFET's on the bucking coil to get voltages up.
4) Maybe try smaller coils to learn more from.
