Hello gentleman. I am new here, and need help from you guys to make this little device work. I would only ask that builders with working devices respond (just as I would like to go to a barber that is not bald or take financial advice from someone that is not broke). Jokes aside, you can see my setup at the picture. I have several straightforward questions so please- concise answers only, no philosophy, visionary speeches and the rest.
1) The question mark on the picture. I don't have scope so I don't know weather my signal generator is outputting both positive and negative when I put it to rectangle wave form- this is why I put a diode at the output, to only get the positive "impulses". My question is weather the input should be only positive (swing the magnetic field in only one direction in the core) or both positive and negative (like a pure sine wave or any other wave form).
2) My partnered output coils are wound one clockwise, the other counter clockwise. My question is: what is the resulting inductance when in correct configuration (bucking mode) - smaller or larger inductance (first or the second picture)?
You can see that I use a small instrument to see the power draw by the amplifier - not the most precise way to measure input power, but good enough I guess. The load is a halogen 10 W (12 V) light bulb.
I can get the bulb to bright full power no problem, but it is a usual transformer effect. I have tried many combinations of flipping the coils, reversing the diodes, many different frequencies, duty cycles, and wave forms, and I have not seen a single anomaly, let alone over unity.
Please guide me in the right direction. The primary coil is 100 turns, and the secondary 300.
Also, I am honored to be here.
