hi NickZ,

The suspicion on high current draw which doesn't allow the meter to reveal the current spikes can be quelled easily by using a large capacitor around 1000uf...4700uf at the circuit input.
I have previously created a youtube "HV to current convertor 2.0" where current draw do not surge upon shorting 5 turns windings.There isn't any increase in current drawn via 1000uf capacitor at input.


The above experiment for this topic is valid.Quite similar concept to the "E-stress" device.

This is a good link with all the related replication videos-(The last video is always the best one capacitor in series with bulb)

Hi!

you wrote:

In fact i have such a big CAP (1000uF) between the circuit and the supply which is just not been shown in the drawings and
video to not complicate this thing.

The cap is connected to the power supply via two diodes (now feedback possible) and a 50 watt Shunt of 0.1 Ohm for measuring the current via scope.
On the scope one could see just very little ripple (< 100mV) on DC voltage / current over shunt.

I do HF measurement since 20 years now and do not cheat myself....

Anyway - thanks to point this out - even I may overlook something someday  ;)

BTW: Yesterday i tried to use a cap on the output L1 and L2 to get DC from the "standing wave" mentioned - that thought was way to short - no DC as expected.
Afterwards obvious..... ::)

BUT: When connecting a CAP (10uF) on the OUTPUT L1, the INPUT drops from  500mA to 1mA !!!! Efficiency increased from 80% to 99% !!! Circuit runs on 1000uF CAP alone for several seconds !!
There is no feedback path to the CAP yet (remember i am using a diode in front of FET)- do not know how power is feed back?

Interesting! I have to take a closer look on this - just had a crude quick and dirty test yesterday and ran out of time - weekend can come....

Hi NoDrawBack,

Please tell where exactly did you connect the 10uF cap?  Stefan shows a schematic on Page 1, first post of this thread, where the bifilar L1 is shown: with wire ends labeled as I and C and J and B
It is possible that the addition of the 10uF increases the AC impedance of the L1 by tuning it towards a parallel resonance, question is whether the brightness of the light bulb (indicated in the schematic as 220V/10W) changes by the 10uF addition or not?

Regarding the observation of member magpwr on the "masking" effect of using a large puffer capacitor:  it is okay that the sudden high current loads are taken from the puffer cap but once we take out charge from the puffer, the supply voltage feeding the cap should start to charge up the cap again, this would mean an increased current draw between the supply output and the cap for during the time the charge is restored in the cap, obviously this supply current would be much less than the sudden high current value. This could be seen across a (second) series current sense resistor placed between the output of the supply and the puffer cap. 
(This process would be analog to a flywheel when you take out mechanical energy from it suddenly and for a short time: the flywheel continues to spin but with a reduced speed, unless you supply the energy to the wheel to increase its rpm to the original one.)

Thanks for the great job you have been doing.

The reason the output goes to zero when DC is applied to L3:

Applying DC from a low impedance source such as a battery or well regulated power supply is effectively the same as shorting L3 as far as high frequencies are concerned. A suitable isolating (blocking) RF choke (inductor) must be added between the source of current and the L3 winding to prevent the effective short circuit.

The effective shorted L3 soaks all the power from the primary coil and dissipates it as heat.

   It would still be a good to idea to test this circuit using a battery, first without the ferrite/copper rod inserted, and also, with the copper rod inside the air core. And do run time tests this way. Also to show a similar bulb running on the grid source, placed next to the test device.
  We really need to determine if the extra bulb brightness is also causing a higher draw, or not. Using higher wattage bulbs, like a 100 watt bulb would also help to displace further doubts.  Big claims need big proof. (1mA ???)

Sorry guys, was an accident. During the 1mA draw test i accidently changed the
DC offset of the function generator which caused the MOSFET not being switched - sorry for the hype....
(as mentioned it was just a crude test)

Anyway - i just made another test using a 220V, 75 Watt light bulb
I am able to get half the brightness, letz assume 30 Watts output.
The input is then 30V@3A equals approx. 90 Watt  whis represents power supply maximum.
(cannot rise voltage  due to MOSFET maximum, must increase duty to inrease power)

Connecting/Disconnecting the bulb does not influence the 3A input current
(used digital-meter, analog-meter and shunt+scope - all the same result - no change on input current/voltage)

The efficiency DOES drop with PWM duty  - that was known already - the lower, the better, but at least 5us for this coil!

sorry, have to cut here now - private issues - more at the weekend

  Ok then, 90 watts input, and 30 watts approximate brightness from the 75 watt bulb.
This I can believe... if I understand it correctly. If not, please correct me.

To clarify: During this 1mA test the light bulb was not connected to the curcuit. I just replaced the bulb by the 10uF cap - so i had no visual observation, just saw the 1mA on the input and then measured the input cap voltage when diconnecting the power supply. The voltage dropped slowly over a few seconds - of course due to no load.
(Accidently activated DC Offset at MOSFET Gate caused the MOSFET not to switch)

Back to topic:
Noone is claiming OU on this device/topic!
This thread should just and only concentrate on the fact that the INPUT does now drop, when a load is attached.
I still do not know/could not imagine how this is possible, how the (electro-)magnetic field here works and what exactly it does?

This device will newer become OU in this constellation, but we need to understand what is going on to built another device
which is able to gain from this effect in a different combination/layout/order/ratio.

We need a device which operates as some kind of regular transformer and uses this additional third NoDrawBack coil from it´s own "waste" somehow.
Remember: All KAPA´s have at least three coils....

  So, does the input drop, now, or not?

  Possibly, the third coil can be connected back to the input, using a rectifier/capacitor, to see if it effects the 3 amp input draw. Otherwise the circuit is just an inverter.
  None of the Kapagen devices are self runners, but they can output several times the input source value.  That in itself is a good starting point.

   Below is a picture of what I'm working on now. Input source is an old 12v, 4aH battery. Output is partially lighting 500 to 700 watts worth of incandescent bulbs, drawing something like 35 to 48 watts.  I have also connected a feed back loop, from the smaller yoke back to the input side. The circuit is not self running, as is, yet.

hi Nickz,

Please do take note full bridge rectifier are not designed for high frequency.Although it seems like a easy way.At high frequency these rectifiers won't able to provide the similar current handling capability due to recovery delay in ns or us in it's diodes.If you take a look at the datasheet near to the bottom of the pdf.There is something like frequency to current handling curve.

Do try assembling a full bridge rectifier which is able to support higher frequency using 200 or 400volts ultra fast diodes.

  I asked Igor what diodes he uses on his home made full wave bridge rectifier. He mentioned any higher voltage ones, but was not specific about it. He uses the diodes that look just like mosfets. When drawing 2kw loads his diodes get hot, also.
  My Mazilli/yoke circuit is not really dealing with HV, I try to keep the volts around 120 to 160v, or so. Higher amps, yes, but it's non shocking current as well, and not the regular hot electricity or normal household wattage. 
  I probably have all the components to make a heftier bridge rectifier set up, and will do so, sometime soon.

The suggestion to use fast diodes for your FWBR is good advice. The ones that look like mosfets are in a TO220 package. A rating around 20A rating should be fine. Make sure you put then on a heat-sink and insulate if necessary.

Hi NickZ,

I collected some ultra fast diode types at Digikey so that you could see the part numbers for them from 600V to 1200V breakdown voltages and from 8A to 15A forward current ratings.  (I do not mean to buy from Digikey of course.)  Here is the link:

http://tinyurl.com/fastdiodes

Perhaps you have a chance to find any of those types (or similar) near to your location.  MUR860G or MUR880EG are mainly used in switchmode power supplies and should be available at several places.  (There is the MURF860G type too which has a full plastic case insulation on its back and the through-hole, so no need for additional insulation when mounting on a heat sink.)
