Bypassing the input transformer and hooking the DC power supply bridge rectifier directly to the mains. Through a line filter of course. The ammeter inline with the DC power indicates the current draw by the MOSFET x-bridge, most of which is going on into the resonator primary. The DC voltage is 171 V no-load; and with full corona it drops to about 150 V, if my meters are accurate. I have more confidence in the amperage reading, especially when the staccato mode is off.
So DC input for the power arc is about 165 v and 3 to 4 amps; the full steady corona sucks up 140 V and 7 or 8 amps.

  • Today I finally got a replacement set of IRFP252 mosfets installed; I remembered that I have these baby moon hubcaps left over from VDG work, so I ditched the toroid and the "capacity pot" as Rosemary called it, and fitted the hubcaps as the topload.

    By theory, two things should happen: 1) resonant freq goes down; and 2) more voltage should build in the disruptive discharge mode, so longer sparks.

    And so it does. It's beautiful and scary.

    I pushed 1.5 kW today; the electrodes melt instantly.

  • jesus ufo chocolate  cake.

  • overunity strawberry cream pie

    You just had to be there.

  • BTW, Great channel.

    Thx TK.

  • thanks, I hope you enjoy some of my other videos. Many are rather pedantic; you can safely skip many of the Ainslie (electric OU) and Mylow madness. My personal favorites are the alt.snakeoil reports.

  • Thanks! There are certainly many that make longer HV sparks, but this one seems to have the best power transfer capability that I have seen in a small tabletop unit.

    It's running at 820 kHz give or take, depending on the toroid and the breakout lead and the ground terminal lengths.

    I think when it makes full steady corona there's probably a lot of power radiated in RF. This week I plan to take it to the lab and check its radiated power, if I can dig out the right instruments from the mess.

  • 300w flame, wow, a mighty flame for 300w.couldnt do that with a normal electri heater. thanks for showing

  • That's probably the best built SSTC I have ever seen! Great work.

    What frequency?

    1KW draw in corona (OU?)?
