Kapanadze Cousin - DALLY FREE ENERGY

[Grumage]

Nobody is making it commercially (I just drew it on a bus 15min ago) but the 2GHz multiplier ADL5391 is not very expensive. It can be had for £6, for example from here or even cheaper sources.
I think, it could change the face of this forum as people could have an accurate and instant confirmation whether their circuits are really OU. 
Also, it can be sold as a standard accessory for a multimeter.  It will show "negative power", too.

P.S.
This circuit could use an addition of overvoltage & overcurrent indicators as well as a multiple-range switch (for R1, R2, R3) ...or autoranging.

Dear Verpies.

That is what us older folk would know as a " Fag packet" schematic !!     I suppose I had better elaborate, Fag packet or cigarette packet !!   

The additional suggestions would also be of great help and maybe a current limit control to stop the FET's from smoking too !! 


Could I assume that you would have no objections to perusing this idea further ?

Cheers Grum.

Go ahead.
Before serious production, this circuit should be vetted by experienced conventional electronic engineers such as, but no limited to: TinselKoala, MileHigh, Poynt99, ION and Hoppy.

The issues that should be looked into are:
1) The influence of internal input impedances of the ADL5391 on the voltage dividers and rest of the circuit.
2) Common mode level (V_MID) of the differential inputs and V_MID overloading_.
3) Influence of the protective diodes D1-D4 on the rest of the circuit, even below their Zener voltages.
4) PCB layout and shielding.
5) Capacitor and resistor values (including values of R1 for various current ranges and values of R2,R3 for various voltage ranges).
6) Consider whether the junction of R1 & R2 (voltage sensing point) should not be on the other side of the Current Sensing Resistor (R1), so the power dissipation occurring in the R1 is not added to the total power measurement.

Further Ideas:
Addition of Voltage and Current Range switches (or autoranging).
Addition of voltage comparators and SR latches (or long monostables) for overcurrent and overvoltage indicators (maybe also driving a cutoff relay in case of an overload).
It is also possible to add a precision rectifier (based on an op-amp) to split the bipolar output signal into two unipolar signals named "Watts In" and "Watts Out", in case anybody ever needs to differentiate between the power drawn from the power supply and the power fed back into the power supply (e.g. Bedini fans). 

@ARMCORTEX
Digital sampling and long-term integration could count the total energy drawn or fed back from the supply.  At that point we might as well add our own digital display since we'd need to have a microcontroller already.

Nick,

You will note from Geo's post that he can match grid lumens with higher rail voltages of 24V and 36V. You should be able to achieve this with a well built Mazzilli and suitable transformer. However, bear in mind that by increasing rail voltage the power consumption will also increase to supply a higher wattage lamp load, so you will need batteries or power supply with sufficient capacity to run this increased load. If Geo can provide you with some device v grid lumen comparative photos and ideally lumen measurements taken using a 'light box', then you will be in a much better position to know if your setup is performing as well as his. As you wish to replicate Geo's RMG setup, he will also need to supply more details about the copper and iron wire used for his transformer and winding / core details. Are the 1.5, 2.5 and 4mm sq conductors actually single solid conductors? I ask this as I've not seen this type of wire sold today, so I'm thinking that he is using wire that was produced many years ago, which you may not be able to procure easily.

HI Hoppy!

Nice to see could be I can help you!

1.5, 2.5 and 4mm sq conductors are at least French very usual standards, for 1.5 and 2.5, for 4mm² no more usual, and can be solid or soft.

Cheers.

O I see now, it would be a good tool. But those projects are always more time consuming than meets the eye. PCB for hf is like voodoo magic sometimes, press power and pray.

Why a scope with carefully isolated probe cannot sense well enough I cannot understand the need ? Where is useability and worth of such circuit Verpies ?

each circuit has commercial value for consumers or  specific useful job to do.

  But, can a scope really tell what's going on with this type of energy? Non shocking, and one that can conduct on only one hair thin wire to a bulb, and the second wire connected from the bulb to a ground. This is not your everyday circuit, or electricity.
  One idea that comes to mind is to use a small battery, like the one the Geo used originally 12v, 1.3ah, and see how long it last while lighting the circuit. Or even two 9v batteries.
If you only get 5 minutes, that would be some kind of proof, but if it lasts 5 hours, or 5 days? What?
  Any way, the main thing is the loop, as Akula has shown.
Or not shown, as our house detective Hoppy would say.
