Pulsed DC Transformer with Embedded Magnets

[ltseung888]

An alternative FLEET configuration:

Could not the two windings be brought down to the bottom, and then be replaced with a centre tap winding? Such an item might be found off the peg. It only remains to cut an aperture out with an angle grinder to fit magnets.

I personally want to keep the flexibility.  We need much tuning before settling on a "production configuration".  You may be able to get the soft iron plates used for transformers in your local stores.  I also want to keep separate Primary and Secondary Coils as I want to try the balanced two magnet configuration.  The Transformer core material is cheap.  The test equipments are much more expensive.

HELP!

Can someone recommended a Pulsed DC source?

We would like to vary the voltage, the frequency and if possible the pulse width.

Thank you.

Handling the low frequency pulse environment

When I was in the swimming pool, it occurred to me that I might already have all the parts needed for testing FLEET in the low frequency environment.  I already have the following:

1.   The timers that can be set to 1/100 of a second (which we used for the Tong Jumping Tube experiment)
2.   The relays that we can use if the current gets high.  (The model we use on the Tong Wheel can handle 40 Amps)
3.   The DC voltmeters and Amp meters
4.   The resistors and lamps  that can be treated as load
5.   The multipurpose meters
6.   The batteries and dozens of magnets of various sizes
7.   The oscilloscope
8.   The wires including those for coil windings

I already know that I can get Pulsed DC by putting a diode in an AC circuit.  I also have diodes.  That can take care of frequency at 50/60 hertz.  I can use the Timer directly or use it to turn the relay on or off.  The variation can be once a second to 100 times a second (100 Hertz).  All I need is to buy the soft iron plates and the insulating liquid to be used between the plates.  Mags already found a 1:1.5 ratio between case 2 and case 3.  I should be able to provide results for the 4 sets of conditions described in an earlier post.  The total cost of material (excluding the oscilloscope) is less than US$100.  The weight is unlikely to exceed 2 Kilograms.  The FLEET size should be less than half an A4 paper.  It is now a matter of tuning to get an Output exceeding Input by 1 watt to satisfy the overunity prize competition.  Who else would like to compete to get a working prototype to Stefan first?

Help will still be needed at higher frequencies.  If the Lead-Out Energy environment were similar to the Tong Wheel (requiring time for the lead-out effect to complete), the above parts might do the trick.  At least I can start the early testing in my bedroom!

Simple variable frequency oscillator 

This is a very simple circuit utilizing a 555 timer IC to generate square wave of frequency that can be adjusted by a potentiometer.

With values given the frequency can be adjusted from a few Hz to several Khz.
To get very low frequencies replace the 0.01uF capacitor with a higher value.
The formula to calculate the frequency is given by:
1/f = 0.69 * C * ( R1 + 2*R2)

The duty cycle is given by:
% duty cycle = 100*(R1+R2)/(R1+ 2*R2)
In order to ensure a 50% (approx.) duty ratio, R1 should be very small when compared to R2. But R1 should be no smaller than 1K.
A good choice would be, R1 in kilohms and R2 in megaohms. You can then select C to fix the range of frequencies.

ltseung888,

How does your Lead-Out Energy differ from that of Nikola Tesla Radiant Energy?
