Hi all,
As someone who has been researching OU systems for a few years, I have relatively recently started work on HHO systems and have built a variety of test cells and circuits, including a PLL auto-tuning system which Dave Lawton originally designed.
I'm now at the stage of examining the optimum HV signal at the electrodes. To that end, I reckon it makes sense to consider what waveform is best to see at the electrode end of the chain and then work backwards to what kit and circuitry is required to deliver it.
In the attached image I have assembled five suggestions for waveforms based on the work of others.
Option 1 is based around the Bob Boyce approach with a ‘resonant’ selection of frequencies superimposed on a full-wave rectified waveform of peak 155V.
Options 2 is the Ed Mitchell approach to Meyer’s system. However, using full ac means that the electrodes are changing polarity with each half cycle so I’m wondering if that is an efficient use of energy. Also, the usual inclusion of a ‘blocking diode’ will surely block the negative half of the cycle anyway.
Options 3 and 4 are non-gated and gated versions of a 50Hz half-wave rectified and stepped up voltage waveforms.
Option 5 is a typical output from feeding a square wave into a transformer, and which only responds well to the rising and falling edges of the input, resulting in more of a spike than mirroring the square waveform. Again this can be stepped up in voltage to a higher level.
There will be of course other waveforms that members believe are ideal to deliver optimum HHO, watergas etc, and depending on whether one is using more conventional electrolysis or the ‘capacitive discharge’ type with distilled water, where the dielectric breaks down, requiring much higher voltages than the conventional type.
So to summarise my question, what do members think is the optimum waveform to exceed Faradaic limits?
Thanks
Jules
