Greater energy coming out then going in.

Can you loop ?

sorry no cigar.
To be honest i cannot be bothered to even begin to tell you where you are fooling yourself. I am sure others will oblige.
However put it into a closed loop system with no batteries involved, then i might be impressed.
here are a few hints on what you did wrong.
1. volts do not equal power
2. you did not take into account the power being fed to the transistor
You really need to lift your game.

Are you an idiot, or what, Volts and amps = power= watts
Anything else?
Don't be an ass!

well I encourage you to contiue, it people like you that help make discoveries. All I ask is you seek some advice on testing procedures before jumping to any conclusions. Like I said close loop it and then you might have me convinced.

Not so fast, c1xc2/c1+c2 is two caps in series
If you have charged a cap at 12v and 32000uf
You have (.5 x .032 x (12^2) = 2.304 joules
If you have to cap at 6v with 32000uf then in Series you will have 12v but less charge:
32000uf x 32000uf
------------------------- = 16000uf
32000uf + 32000uf
(.5 x (c1c2/c1+c2) x ((6v+6v)^2)=1.152 joules
Parallel is 1/c1+c2 or:
.5 x (.032000uf+.032000uf) x (6v^2)= 1.152
But the total was starting cap was:
.5 x .032 x (12^2) =2.304 joules from the start.
50% lost of energy going to second cap.

Mark,
You're right about the pwm not being powered by the cap.
The voltage drops from the main cap, this cause the pwm not to work after 9v.
That is why I used a battery to power the pwm only.

thanks Tom,
by the way I do like your videos and your experiments. Thats why I encourage you. You solar inverter is a great solution and would save a lot of people money who cannot afford expensive solid state devices.
Like I said I encourage you very much...however just think through your testing procedures sometimes.
I am sure many others enjoy your posts as well and your video's
The reason I am a hard arse skeptic sometimes I have seen mistakes made by people all over the world when it came to testing their own devices. I have seen electrical engineers make mistakes as well. Please do not take offence.

Now if my calculation are right, then using a pre-charge cap to charge the second one has a lost of 50%.
c1xc2/c1+c2 is two caps in series
If you have charged a cap at 12v and 32000uf
You have (.5 x .032 x (12^2) = 2.304 joules
If you have to cap at 6v with 32000uf then in Series you will have 12v but less charge:
32000uf x 32000uf
------------------------- = 16000uf
32000uf + 32000uf
(.5 x (c1c2/c1+c2) x ((6v+6v)^2)=1.152 joules
Parallel is 1/c1+c2 or:
.5 x (.032000uf+.032000uf) x (6v^2)= 1.152
But the total was starting cap was:
.5 x .032 x (12^2) =2.304 joules from the start.
50% lost of energy going to second cap.
Did I make any mistakes?

Hi Tom,
Your calculations seems correct, they reflect the 50% loss you also show in practice.
Maybe you have seen this but if not, here is a file uploaded by member poynt99 here: http://www.overunity.com/index.php?action=downloads;sa=view;down=209
He figured out how to reduce this 50% loss by using an appropiate coil for the charge transfer between the two capacitors.
Thanks, Gyula

Thanks for the info, love information.
So when I discharge from the pulse generator, where did the extra energy come from the second cap?
As my test shows using a charge cap to discharge into the pulse generator, at the same time the pulser allow more energy into the second capacitor.
This is the test:

The pwm was run on a battery to control the mosfet.

Tom,
In your video you started with 12.92V in one cap and ended up with about 7.7V in each after transfer through your PWM circuit. This is an improvement over direct transfer through a piece of wire where you would get about 6.46V on each.
The 7.7V on each does not show "extra' energy of any kind, but what it does show is less loss. With a piece of wire you lose 50% of the energy, no argument. With an inductor (your PWM circuit including the coil) this gives you less loss, but you are far far from perfect.
7.7V is an improvement, but if you try harder, you will be able to obtain about 8.9V on each cap. If you achieve this, your circuit will be running at about 95% efficiency. Sorry, still no OU.

Ok, I'll take that. I was showing in my videos that energy from pre charge cap going into another cap was a loss. That's why I said 50% loss of transfer energy.

Hi tom good day
how did you made your PWM?
i mean how could it last the switching on and off?
God bless
otits ;D

Tom, Keep experimenting. Trust me, I've been down the road your on before. Try putting a small DC motor in series between the caps, and see how much energy it actually uses to do work. http://www.youtube.com/watch?v=vwp7podu06s fun little mind experiment that really get's you thinking!
Long story short, an inductor, and pulses do decrease losses. 99 is right in this respect, like I said, been down that road haven't we 99 :P . But it does not mean extra energy is entering the circuit yet unfortunately. Capacitors are lossy as hell. But it's when you start realizing you can be get work done, while you retrieve half the energy that you start seeing efficiency climb. Good luck.

Otits,
The pulse generator is design so the kick back effect wont destroy the mosfet.
Think of one way valves, power goes in, and the kick back (or say fly back), goes into the cap.
If you add a diode to a coil, the fly back is shorted out to prevent the mosfet from being zap from the high voltage kick back.
I use 4 diodes for that reason, but add a cap into the center of the 2 diodes to collect the back emf.
Tom.
