Thanks for the comment. The secondary has a resonant frequency of about 250khz (calculated) with a 3x12" toroid topload, without i wouldnt have a clue...probably about 300 to 350khz. The primary consists of 4 turns of cat-5 network cable around a cardboard tube, the pairs of cable are connected parallel to give 16 turns tapable at 16,12,8, and 4 turns, in this vid it is tapped at turn 8. I am feeding fullwave recified 240v mains to the bridge, so 340v peak.
Pretty damn good. What's the primary, and what are you feeding the h-bridge? What's the ring frequency of the secondary?
