Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

On multiple discharge:
If you want to discharge the capacitor 3 times, you will have to be very quick to charge it up.
I don't think it is practical.
My proposal is to charge the 3 capacitors prior to reaching TDC and firing them at desired intervals.
This puts heavy demands on the circuit design.

Hi gmeast,

Thanks for your average current draw calculation. Since the way I understand your circuit, all power comes from the inverter, can you measure inverter current draw from the battery to compare it with the calculation? I am not sure if it will be pulsing or will be filtered by the inverter internal capacitors, etc.

Hi insane4evr,

I have taken the measurement with an analog amp meter and here are the results with final calcs in watts:

First the pulse power calcs again:
5,000 Rpm = 83.33cycle per sec.X 4-Cyl / 2(for 4-stroke engine) = 166.7 pulses per sec
&
12.5 ohm current limiter to Mosfet through 134V (charge) = 10.72 A
&
scope says 2.5 ms per pulse charge but it's a 'ramp up' = 1/2 = 1.25 ms per pulse (ave)
so ... duty cycle is 1.25 ms/pls X 166.7pls/sec. = .208 (this is now dimensionless factor)
therefore:
10.72 A X .208 = 2.234 A

looking at the capture from the scope (1st photo below) it resembles a sine wave somewhat, so we can use 0.707 X 134V in the average power calc:
.707 X 134V X 2.234A = 211.6 Watts.
Wp = 211.6 W

Now,

the alternator was putting out 13VDC
the analog amp meter (2nd & 3rd photo below) read 16 A
13V X 16A = 208 Watts
Wi = 208 W

and Wp agrees pretty good with Wi.  Compared 211.6 W to 208 W.

Peace,

Greg

@gmeast,

Thanks for doing the math...

So a smaller inverter wouldn't work ?...... the inverter has to be 400w or more ?

Thanks for your time..

Hi

I was also thinking something along that line, well I though using 3 set of CDIs might do it. Each capacitor is charged in turn such that the load on the inverter is spread throughout each revolution. Then the 3 capacitors are discharge sequentially within let say that 10 deg.

I dont know if its beneficial or not, I wont bother with it at the moment.

Man you really know your stuff. And a mathematician even.

Thank you very much.
