Pulsed signal 60% more effective then strait DC

[Hidden]

Hi folks,

As result of the negative " resonance" spike that i found
(http://www.ionizationx.com/index.php/topic,1172.msg12319/topicseen.html#msg12319)
i continued with my coil collection, to see how to harvest that spike and re-use it in the proces.

Here are the numbers:
Reference point, strait DC with cell : 0.50Amp x 1.79V=0.895Watts

Coilsetup:
Circuit with coil and cell = 2,4vr x 0.29amp= 0.695Watts = totall consumed power of the circuit with cell.
Measured what is going into cell (after the coil)= 1.79v x 0.50amp=0.895Watts

Thats 28% less power in then with strait DC but still same volts and amps entering the cell.

Coil = big toroid
Frequency= 640hz
Mark= 60%
Space= 40%

I re-ran this test more then 4 times. Always the same conclusion.

Stevie , that picture you showed is a classic curve , I can show you the same exact curve with this 2n4401 ,  nothing but a saturated transistor that has problems getting unsaturated .  Your transistor is probably dissipating that missing power . This is due to excessive base current and too large a storage time

Nothing special here Stevie ...

What does that have to do with my claim here?

My question to you all:

Where does this extra power come from?
Coil? Water? tubes?

There is no extra power , only lower power dissipated in your cell because your switching device is now acting as a resistor .

It has to do with the way you are pulsing is total crap .

Do a google search for a purpously made "mosfet driver" , then buy a power mofset .

Make sure the mosfet driver is compatible with your pulsing logic level .

Make sure to keep the leads very short , and put a bypass capacitor , as shown in the datasheet of the mosfet driver .
