Kapanadze Cousin - DALLY FREE ENERGY

[magpwr]

hi everyone,

The last couple of days was merely  circuit testing and testing as shown in my youtube video.

Come this weekend i shall carry actual testing with the kapanadze coil base on 2x L/C resonance at low voltage around 24volts then to mains dc voltage 250VDC.

Using only the 3 turns to kapandze coil.For my case the 250VDC is easily stepped down via 10kv diode which lower voltage by around 50volts to around 200volts(across another 20uf 400volts Russian PIO capacitor) for the Transponder circuit.
In one go i have solved my hv supply headache.

It seem less complicated playing with high voltage and reducing the duty cycle.

I have attached to show the waveform at both the 1.2kv SIC Mosfet gates before and after powering on the 12-220volts inverter which provide the 250VDC
You can see there is hardly any interference from the toroid.

No loseless clamp circuit needed since 1.2kv mosfet gate capacitance is mere 950pf is hard driven via 2.2Ohms 2watt resistor with SS36 or suitable SK diode in parallel direct from UC3825N PWM I/C.

For high voltage supply-

I am using what seems to be world smallest China made 150watt 12volts to 220volts inverter purchased from ebay.The circuit runs at 73khz 40% duty to give 250VDC  after internal full-bridge rectification.The 50hz modified sine-wave is produce at it's internal full-bridge mosfet output.

------------------------------------------------------------------------------

Lastly before soldering both SIC Mosfet onto breadboard i have forgotten to put 1 tiny bead for one of the Mosfet Gate.

Observe carefully only one mosfet produce the spike across gate.That is the mosfet which i have forgotten to install 1 ferrite bead.

The ferrite bead is the suppressor for high frequency spike.But this bead cannot be used in tesla coil transistor or nanosecond generator mosfet gate at all.It's meant for low frequency PWM.

Please ignore amplitude for Mosfet gate because i am using 2 different 600volts probes.


-------------------------------
After this final tip i shall not discuss about any basic PWM circuit problems.


--------------------------------------
Lastly the black object which i previously thought was a capacitor to Earth for Vasmus device was just a micro switch or push to off switch.

This is seen clearly  in Vasmus 2 video at 3:09 .

I must point out, that the lossless clamp circuit is active in the drain circuit ...not in the gate circuit.

  Has it been proven that the loss-less clamp is a waist of time and effort???
  Why not continue with what has been shown to work, instead of second guessing the outcome of this unproven clamping system with the Akula/Ruslan devices?  Seams like a long derailment of the Ruslan type of replication.
   
   Several of you guys are still using the smaller yokes, instead of the 3 inch one. The small diameter yokes (2 1/2 inch) were not working for Akula on his first tests, and he went for the 3 inch ones instead. Remember?
   
   There are even bigger Tv yokes, like the 4 inch yokes, on the older 34 inch CRT Tv.  More room for the clamp windings, if still interested in going that route.  But, using thinner wire, such as the audio stereo cable, may lead to less amps at the output.

No. Just the opposite.

  Really?  And where is the proof of that, in relation to the current tests?
