Understanding JL Naudin's WFC Replication
« on: April 07, 2011, 19:51:03 pm »
After a bit of study of JL Naudin's circuit, it seems quite easy to replicate the WFC on a small scale using a very simple circuit. This post is to help everyone better understand JL Naudin's replication, and to understand what type of circuit he used.

JL Naudin’s Water Fuel Cell replication is shown and explained on his website at:
http://jnaudin.free.fr/wfc/index.htm

First, we see the video on his page showing the cell producing hydrogen-oxygen gas, and just above the video he states the following:

“Below, the video of the experimental WFC v1.0 working in resonance mode with distilled water. A high flow of gases is produced at the WFC v1.0 resonance frequency. You may notice that, in this case, the size of the bubbles produced are very tiny compared to a common electrolysis process.”
Note the video is version 1.0, which is using DISTILLED WATER.

He later insulated the capacitor, calling it version 1.1. However, he never stated that version 1.1 produced any gas. He does go on to show how this capacitor charges and discharges on the oscilloscope. He also shows the step charging of the version 1.1 capacitor.

On the website Naudin gives some information about the circuit which can be used to determine what kind of circuit it actually is.

“The T1 transformer is a common 220v/12v 60VA transformer used in reverse mode. The use of a toroïdal transformer with a ferrite core will be better to minimize the HF losses in the core. The T2 transformer uses a bifilar coils as described below”

Note that the transformer used is a 220/12V transformer used in reverse. Thus the transformer has a step up turns ratio of 1:18.3. (12/220=18.3) On the first diagram (attached below) you can see the 30V power supply (circled in red). 30V applied to the primary coil would give us 550V at the secondary (30V X 18.3 = 550V).

On the second diagram (attached below) you can see the waveform peaks at 488V, not quite 550 due to losses.

On the third diagram (attached below) you can see the voltage peaks at 1,008V, nearly double the supply voltage of 550V.

So, in the circuit we have a water capacitor which charges to 2X the supply voltage. There is only 1 kind of series resonant circuit which charges a capacitor to 2X supply. The circuit used in Naudin's replication is a DC resonant charging circuit.
In the DC resonant charging circuit the capacitor is charged to 2X supply because of the inductive collapse. The supply first charges the capacitor to the supply voltage, once this occurs the current stops flowing through the circuit (because the cap is charged) and inductive collapse forces more current to the capacitor which charges it to 2X the supply voltage. It takes many cycles for the cap to be charged to 2X supply, but once it reaches that point the voltage will not get any higher.

Although Naudin used a DC resonant charging circuit to replicate Meyer, the circuit Meyer used operated in a slightly different way. Naudin's replication has shown that a DC resonant charging circuit can be used to replicate Meyer on a small scale.
