Warren, powerfull. big battery is perfect.
A man on a video described how it makes the FETs blow because of weak drive.
I too have induction cooktop and the circuits are really ideal with little software control so just finfd out what the magnetic sensor does to prevent shut-down.No PLL used and the PF is 1 because no big DC filtering caps so output pulses follow line phase aptitude. only uses like 4 op amps and hard driving IGBT.It's a repeating one shot circuit actually.
Then determine the freq range that works then use caps or L adjustment to suit. I'v seen convincing video of OU on these IH cookers,Tesla pancake bifillar driving resistance load 1:3 gain in power.

Dave What do you mean by a "stiff" power supply?Would two golf cart 6 volt batteries, in series, be considered "stiff" if needed?
The whole point about using the device is to attempt to obtain more output than input, by means of Tesla pancake coils, if, in fact, it is possible.My experiment with driving the three hp DC treadmill motor much like a Dremel tool, at screaming high speed, using a pancake coil made from tiny speaker wire on a cheap Walmart induction stove, until the stove shut down, makes me optimistic about this route to over unity.The stove top is OK to generate the frequency, but the software of the stove shuts it off, because some detection circuit thinks you are not frying eggs in a cast iron pan, like you should be. You are misbehaving, so it shuts off to avoid a law suit.I had hoped the Chinese induction furnace driver was naked of baby safety software, and would explode, and burn, rather than shutting down.Obviously, I would not wish to uselessly destroy a piece of apparatus, but want to be free of quirky software issues.

I bought some Ebay Beofeng HTs before FCC screws with them. 5 and 8 watt , 2 and .7 meters bands with extra freq. beyond HAM.Only about 25 each. I always wanted a strong pair of walky talkys.I think there are easy to hack and use SDR tech
Check out RF circulators, used to stop back reflections.A 3 port device with a load on one port to arrest offending power.They are a trip to figure out but I think they could be usefull in our OU work.They use a 2 magnets with ferrite surrounding a triangle of copper with each point being one port.
