ENERGY AMPLIFICATION

[GT899]

Hi I have done a bit more testing today.
You mention doing something with the energy from the collapsing field of the driver coil so I wired up a diode back to the capacitor so perhaps as to feed energy back into the capacitor from the collapsing field. It certainly helped as it continued to work for more than a minute after turning the PSU off where as before it would stop rather quickly.
I also connected a 12v lamp there before I tried out the diode and it did not affect the output of the collector coils.

I made another pancake coil today so am using 3 collector coils. At best there very crude so efficiency is not exactly perfect at all but surely with enough collector coils and as mentioned before feeding perhaps more driver coils I presume this would be sufficient?

I wired up 20 bright white leds in parallel to the output collector coils and they light them up at full brightness but the output is pulsed with the mechanical switch sparks. So there flickering very fast almost like strobe lights at times.

When the motor flywheel reaches full speed the output is lessened and the led's are very dim. As the motor starts to slow down again and the plates make more solid contact with the brushes the brightness then increases considerably, I suppose that is because there is not sufficient contact on the brushes anymore at max speed. Every now and again I have to press the brushes back onto the plate as they get pushed away.
However dead shorting it with no pulsed make break results in zero volts from the collector coils

Perhaps a solid state make break switch would be better? Easier to work with at least.

Here is an interesting video with pancake coils:  http://www.youtube.com/watch?v=32CZzeqqgzU

If you take a coil tuned with a capacitor in parallel and pulse it with narrow DC pulses from a circuit, then when resonance of the coil being pulsed is reached the collapsing field energy goes into the sine wave produced (in the tank) and a sine wave also appears on the drain of the mosfet or switch supply voltage (in some circumstances). In other words the spike from the inductive release adds to the resonant waveform and the main inductive spike is no more. In this situation even if a diode is used to try to gather the inductive release "power spike" no spike "proper" will be there to capture, due to resonance.

However if too much power is used before finding resonance and big spikes are produced they can destroy a semiconductor type switch during tuning, careful tuning and pulse width control is helpful. Also knowing the ballpark figure of resonance beforehand and setting a close frequency on the pulsing circuit helps.

eg, a 1:1 transformer is setup using the secondary as a tank by tuning it with a capacitor, if the primary is pulsed at low frequency with DC pulses and a diode is used at the negative end of the primary to capture the inductive release spike and a second battery is charged with it, then as resonance is reached on the secondary coil by tuning the input pulse frequency, the charge output from the diode pretty much stops, due to the spike being incorporated into the energy into the oscillating energy in the tank.   

I can show this happening. 

Cheers

P.S. Contrary to the popular belief that resonant tanks are (inherently efficient) they dissipate power the same ways any other elements dissipate power, the oscillating current in the tank burns off power relative to the DC resistance it encounters, in the wire and the capacitor. Also with higher frequencies there is RF losses as another example.

Even though a huge oscillating power can be obtained with a high "Q" Tank being supplied by a small input, the input is replacing the losses only when there is no other loading than the losses.. And if energy is taken from the "Tank" for an external load then the Tank energy will be replaced at the rate of the input (as it does it). The higher the voltage and current in the tank the higher the losses so adding a light load can reduce the losses if it reduces the oscillating power in the "Tank".

@Tito,


thank you sir..


@Tito and All,


Ok, please teach me. i want to charge my 0.5uF(2000V) capacitor very very fast, in milli seconds or less.


please help....


Thanks
