Pulsed DC Transformer with Embedded Magnets

[The Observer]

I made this for my

Magnetic Permeability ... I can't find anyone talking about this !!!!!

This all comes into play.. if you are playing with a Ferro Core Transformer..

Paul,

You're must be psychic.
I broke a flyback 3 days ago... took the core and wound a 200 turns with another 15 around that.

With a 1 volt DC square pulse(0 to 1 volt) at resonance (~20 Khz) it produces an AC Sine Wave 15 Volts Peak to Peak.

Diode and regular voltmeter produced 5 volts... l volt or less out of resonance.

Tseung... You are on the right track...
               -  Resonance.. Yes
               - Square Pulses... Yes
                -Magnet inside A... Ya, I'm not sure about that.
                                                                 ... I implore you to study Magnetic Domains, Ferro Dipoles, Anistropic Energy
                                                                      and Magnetic Permeability.
                 
Bottom line is that a transformer is really an electromagnet... where the  small Magnetic Field of the coil
                                                                                                                   is amplified 10,000 times with a Ferro Core !

So, it's kind of hard to turn on and off an electromagnet if there is already a magnet attached to it.
       and since the Field of the Core Colapses on it's own "pell mell", a magnet really isn't doing anything different.

That's my point.

Have a Great Day !

Thank you.  We shall try without the magnet first.  If that produces good results, we shall treat the magnet part as academic exercise for the research students.  Matching coil strength and magnet strength will be additional work. 

Can you capture the Input and Output waveforms on an oscilloscope?  Can your scope display power?

Mr. T.

I composed the following in response to your request for Screen Shots.
I do not have a power setting on my O-Scope.

Dear Observer,

When you use different turns on the primary and the secondary, you are effectively producing a step up or step down transformer.  With 15 turns on the primary and 200 turns on the secondary, you essentially step up the voltage by 200/15 or 13.3 times.  That did not demonstrate that energy was lead-out nor overunity.

You can put a 1 ohm resistor in series and measure the voltage across it on the scope.  That would indicate the current(V=IR).  The voltage and current for Input can be shown at the same time.  Repeat that for the Output.  We can learn much more.  If your scope allows the display of product of two channels, you can effectively display the power (P=IV).  The area under the power curve for a given time represents the energy (Energy = Power x Time) 

I also have some doubts on the display of the Input Voltage.  I expected to see rectangular pulses in  the positive direction only.  Can you check and explain the display more?  Thank you.

We are all learning from your efforts.  The World will benefit.

Mr. T

Yes it is a step up transformer.
That is evident from the pulses in first screen shot.
The top Voltage is the Primary...
The bottom Voltage is the Secondary.

However...you say

I expected to see rectangular pulses in  the positive direction only.

You won't see the square wave when it is hooked up to an inductor (or electromagnet).

         1. You see the rise time at front end of pulse. (domains lining up to amplify coil's Magnetic Field)
         2. You see nothing in middle of pulse. (steady current means no change in Magnetic Field... domains all in 1 direction)
         3. You see decay rise time at end of pulse. (this is when the magnetic domains return to random directions)
             - a mirror of the front pulse rise time , but from the opposite direction.

When the pulses approach the size of the resonant ring... this is when things add up.

Remember that the secondary ONLY reacts to a changing magnetic field.
Even though Current is flowing through the Primary after the rise time... you will see nothing in the Seconday.

Now at Resonance... the primary is an AC sine wave
                                    Not a DC Square wave
                                    ...remember the back pulse from the collapsing domains.

I shall try some power calculations in the near future.
