Shorting coil gives back more power

[Tito L. Oracion]

Hi penno64


I think I have an idea.. If you may sir, Why not use the driving transistor as shorting device? How? Have you seen how the HOT of TV/Monitor works?

ya that's a brilliant idea!!! 

KABAYAN!!!

Thank You Sir  almost done na po sa muller dynamo.. Hope it will run..

Ok, I'm playing the coil shorting game. I've got the avr shorting the coils at the peaks of each wave. Its not slowing the rotor down at all with or without the buffer caps hooked up. It does VERY slightly slow the rotor down when I start applying the shorts, but only noticeable with a meter. Caps with small uf are charged instantly. Now I just need to flip a logic 1 (+5v) to a logic 0 through a circuit to try and grab that charge and send it to a load.

I got that working, but the output to load is next to nothing... oh well.

The reasons would be clear if you would look the current graph...

- when you short current starts to flow
- inductive reactance resists current flow
- by the time you unshort only very minute current had time to build up
- backspike will be HV but it will also contain only minute amount of energy

I have not yet found the way sneak around these problems with gain over conventional generation. Has anyone?
