I've made a video showing the working experiment producing 950Vdc:https://youtu.be/KbtK9jrk_JI
Very impressive, thanks for the vid.The caps load in about 1 sec, that's about 1.6uF * 900sqr /2...about 64 millijoule/s.Anyway, it would be easier if you used a certain load, such as a 100 Ohm resistor, then you measure amps * volts = watts, and compare it with input watts. It is however an unusual way to step a voltage up. A standing wave does that. From my POV the art of profession would be an automatic frequency adjuster that compensates for the output that usually kills the resonance.Anyway, interesting stuff.
I'm not sure I understand Evo ,your pulsing the middle coil, and the two outside coils are putting out 900 volts?
I find this very intriguing ,if I could raise my voltage to those levels, I would think a self runner is inevitable.
Speculation from here on: The ratio between voltage in and out is around 77
evostars, you need to get the loading time into the calculation. Your caps cannot deliver 900vdc constantly. This only how high the voltage goes at max. It's the noload voltage.Again, 900*900=81'000*1.6uF=~128milli *0.5=64 millijoule. How do you get 1.8 Joule?Anyway, by adding a load such as a 100 ohm resistor, you can calculate the amps based on voltage. If the voltage were 200vdc at the load, then it were 200 vdc / 100 ohm= 2 ampere. And hat would be 200 vdc * 2 amps = 400 Watt.Then again, your yellow multimeter looks like it has amp section.Well, it may be relatively easy to autoadjust the frequency to resonance, the sam way tv and radio did it to follow a drifting station. I think it was termed AFC? Raher simple circuit.
Quite interesting considering the turns ratio is one to one. At first glance with two coils, one would think 24 volts is about all you would get out of there. A rather novel form of boost converter you have assembled there Evo. I'll bet getting that 180 degree phase relationship was tricky to do. Does it move around when the storage capacitors are charging?So these coils produce a nice sine wave even though you are injecting a short duration pulse? What's the approximate duty cycle?
Dear evostars.You could get one of these for your input measurements.http://www.ebay.co.uk/itm/Digital-LCD-60V-100A-Balance-Voltage-RC-Battery-Power-Analyzer-DC-Watt-Meter-CI-/272291431181?hash=item3f65d5830dI recently bought one but have not used it in any practical way yet.Measuring the output will be a whole different " ball game " though.Cheers Graham.
