Hello friends.

I just put this thing together, and wonder if anyone has comments.

RobertD · « **Reply #1 on:** November 19, 2017, 10:21:01 PM »

What you see is four (or twelve parallel) auto ignition coils. A spark plug, going into a high voltage primary through a diode, stepped back down to 12v, I would guess with a lot more amps than needed to drive this circuit, how much I can't tell you, but I think a lot. An arduino type of uC triggers the coils one after another, the more the better. The frequency is regulated by a microprocessor that can optimize for resonance. More coils allows higher frequency and more power.

I put #5 to show that more coils can be added.
Tesla said more power comes with high voltage and high frequency.
I think this can work. I have everything I need to build one with one coil.

I think this can drive a forklift motor.

A large step down transformer is needed so not quench any of the available power.
I'll make my own step down transformer to have an idea of what I need.
I'll use a MOT for trial. The 110 side because of the bigger wire, and use maybe 3-4 turns 3gauge wire for the output.

It will have to be rectified of course. And go through a golf cart driver circuit.
The stepped down voltage used is what you need for
the particular application, some forklift motors run on 36v.

Would need a separate coil for 12v.

My set up would be for the driver circuit to produce what is needed for constant speed driving, and to have a
supercap or battery bank for peak usage like acceleration or climbing. The circuit will charge the backup power during
low demand time, like city stop and go.

Hey guys, what's taking so long?
I posted it on Twitter already .
And other places.

Thanks guys. Looking forward to see what comes of this.

Building the prototype, a couple of things I have to change. The MOT high voltage winding has to be the high voltage since the 110 side won't have enough reduction. And I'll try without the diodes first.

Its all about power in and power out and watts is the best way do get that
electrically. Many great ideas fail this test. ie Milkovic and his hand powered
easy pushed but not measured pendulum fails that test.

As far as what Tesla said and Don Smith says that too but
remember short pulses are also short time and watts has a time factor too.

So 1 watt for a tenth of a second is 1/10 of a watt.

1 watt for a second is 1 watt.

Most people would try to get backemf from AC but you have DC and can't get that.

That's not the way to do it you need 2 spark gaps per HV supply one to limit the EHT voltage and another to collect the ionized partials going to your collector coil E V Grey tube.

I would reply, but then it would not be RobertDepelteau circuit then

It should not matter AC or DC. If you power an inductor and then cut the power there will be a back EMF. Or just pulse a primary with DC and get AC to the secondary if I'm wrong on the first one

Dear RD

You have your 14kV to 12v transformer labelled +/- on the output.

As you probably already know, the time averaged output of a transformer can never have a DC component, it's time averaged sum must always equal zero. (as Norman commented earlier)

If you indeed have a DC component on the output, you have something novel and should patent it quickly.

You can easily test for a DC component with an R-C filter on the output, e.g. an AC capacitor of 1uF in series with a I megohm resistor will give you a time constant of 1 second which should average out the noise of the spark gaps. Read the voltage across the capacitor on the DC scale of your meter.

I suspect with the applied filter you will see no net DC component.

Careful shielding will be required as most meters are strongly affected by intense local EMI, which will certainly be present in the vicinity of your spark gaps.

By the way do you have a hypothesis of what the circuit is supposed to do and if it produces excess power? There are easy ways to test for this if that is the claim, and I can help you with the testing.. If not, then it is just an energy wasteful invertor circuit.

Good luck and happy experimenting

Regards

I was going to add one might also just publish the work as widespread as possible but didn't want to get too wordy. The main thrust of the reply was technical not political. I just meant that it would be truly novel to get DC out of a transformer without post rectification (also without asymmetrical saturation effects of course).

Yes patenting is a bad idea, it was said in jest.

RobertD · « **Reply #12 on:** January 26, 2018, 04:17:03 AM »

Always looking for better yields.
Once an idea is put in the public domain it's no longer patentable.
Of course the output is 12v AC. Rectified it gives 12v DC. The ignition coils are supplied with 12v DC, interrupted by the uC in turns. The output is fed directly into the MOT high voltage coil. After thinking and putting the transformer together, I decided not to use the 110 side as a primary cuz 35kv won't drop to 12v with only 120/3 turns. So it's even easier to build using the MOT as is. It will output around 300v AC, so I can plug a heater in it directly.

RobertD · « **Reply #13 on:** January 26, 2018, 04:23:20 AM »

Turns out ignition coils can be fed 50v to 70v and normally output 30/40kv. So my numbers are off. Turns out also that the ignition coils output back EMF to the spark plugs, so the diodes should be reversed. Right now I'm experimenting without diodes. Resonance should be a factor in choosing the frequency. With three coils which one should I resonate? Me thinks the high voltage on the MOT.

RobertD · « **Reply #14 on:** January 26, 2018, 04:27:49 AM »

It's probably a good idea to push the ignition coil as hard as it will take it. The higher the voltage the better the yield.
