Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

We already know that varying the freq. of the loop with delays varies the current draw.    Why not purposely set alternating groups of delays to simulate variation of current!!  Does this make sense?

A simple test: Set the Arduino to 50Hz and via a cap modulate the pot-input from a  signal-generator (sinus, square? etc.) with a lower freq.

Yes, I believe this has to be synced to a harmonic of the FULLWAVE of the code.  I may be wrong on this. 


Also, along your thoughts, the original code had a ADC value mapped to the delay value.  So yes, a sine, square..etc.. to the ADC is a possibility.   If you look at this approach,  Pierre could have used a SQUARE wave to alternate the delay values.  I see alternation of two sets on his scope shot!

A very interesting video Luc.
Am glad the Propeller has sorted things, perhaps also because your friend nearby can actually look at any problems to fix them and likely could do so far quicker than shooting videos etc for help here.
If it works it works

So...you pull coil 30 and things improve. Do you think that there is a secondly function of the microcontroller code ?
To create an imbalance and, for want of better words, the natural entropy is what manifests as an OU situation for those split microseconds of every time it changes ? That section would tie into the PWM thoughts and apologies to all if i'm slow on that one !
Or, perhaps, remove 30, 24, 18, 12, 6 and see what happens.

For comparison

Actually your waveform is not too bad Gotoluc!

Added the adjacent poles.
