   With:
   
   
   THIS MEASUREMENT WAS OVER THE CELL!
   
   - A pulse train about 20 pulses
   - @ aprox 62.4khz, 100us interval between pulse trains
   - 2 chokes (b+ 4H, b- 1.3H)
   - transformer made from TV flyback (pri=8T. (80uH, sec. 800mH aprox 700T.)
   - Vin 50V
   - Amps: 0.1
   
   Smallbtiny bubbles appearing.
   
   When we fall about 2KHZ waveform almost desapear, rising up the same behavior.
   
   Anyone saw this strange effect? Only can get it with transformer closing the circuit.
   
   This is the second time i saw this, but rarely i can replicate this strange effect.
   
   The waveform is sinusoiodal when we change the scope time to zoom in.
