... , you have something novel and should patent it quickly.

I was going to add one might also just publish the work as widespread as possible but didn't want to get too wordy. The main thrust of the reply was technical not political. I just meant that it would be truly novel to get DC out of a transformer without post rectification (also without asymmetrical saturation effects of course).

Yes patenting is a bad idea, it was said in jest.

Always looking for better yields.
Once an idea is put in the public domain it's no longer patentable.
Of course the output is 12v AC. Rectified it gives 12v DC. The ignition coils are supplied with 12v DC, interrupted by the uC in turns. The output is fed directly into the MOT high voltage coil. After thinking and putting the transformer together, I decided not to use the 110 side as a primary cuz 35kv won't drop to 12v with only 120/3 turns. So it's even easier to build using the MOT as is. It will output around 300v AC, so I can plug a heater in it directly.

Turns out ignition coils can be fed 50v to 70v and normally output 30/40kv. So my numbers are off. Turns out also that the ignition coils output back EMF to the spark plugs, so the diodes should be reversed. Right now I'm experimenting without diodes. Resonance should be a factor in choosing the frequency. With three coils which one should I resonate? Me thinks the high voltage on the MOT.

It's probably a good idea to push the ignition coil as hard as it will take it. The higher the voltage the better the yield.
