Allan's Transformer as a Generator

[leonelogb]

Hi Jeg,

It is best to only concentrate on the link and the flux because for in transformer power and size calculations it is not considered.

The magnetizing current could be 15% of the load but as was explained previously not all that current is used to make the flux.
With 240volts, in one instant only wire resistance is seen and then in another instant to create opposing flux that is 80% on the way to saturation of the core.
The magnetizing current is 90degrees out of phase with the reflected load current and by vectors the sum of the two add to very little more than the load current alone.

When the Flux is generated by a floating supply between the I/P and O/P windings it becomes a generator. The capacitor input produces the swings of potential that are reflected in the output as well.

In a generator it is the rate of change of the magnetic field and the strength of that field that gives the output. It is just being done in two coils at once while their magnetic fields cancel at maximum current.

Calculations can be used to size but it has to be determined how much extra flux is acceptable at a certain frequency. The core material may get too hot and at high frequency be destroyed.

The flux increase could be up to four times increased and would mean less turns, less heat in the windings but more in the core.

Hi Allen,

I would like to understand how the diagram you put in the link above is structured.
I think I am understanding the concept of the two main coils, one cw and one ccw as you have already explained on different occasions, it looks like what Chris has been talking about, Although they seem different, I think it is the same but with different applications, If you are kind enough to complete the questions and details that are in it, please!

The way you have managed to control the power supply of the bucking coil through a minimum input is the first part that I would like to understand, so I break down the diagram to be able to understand its details clearly,

Another thing, I am planning to make a small book with his teachings and diagrams, do not worry that it is not to sell, just to read several times until I understand everything God willing.

Hi Leonelogb,

The windings are wound in the same direction on the core but the current goes through them in opposite directions.

The main circuit windings I/P, O/P are of bigger area, or larger diameter, because more current flows through them.

I have 0.8mm enameled copper therefore this is used for the smaller wire. It is best to have 15% difference in turns between the large diameter and the smaller.

I have used 1.5mm for the heavier enameled wire for up to 15 ampere and the 0.8mm for up to  2 ampere.

If the larger diameter wire has 40turns then the smaller diameter wire will be 15% different, if more 46turns if less 34turns make a tapping in the 0.8mm windings and color code them.

The core will be wound with all of them and will need to be worked out. I have previously used two cores with the two windings on each.

I reuse the enameled wire from big transformers that have been pulled apart. Insulation material is used between layers when winding is done.

Two inverters are off the same controller and consist of 4 square wave pulses one after the other. for a first try use a 555 and a 4017, a buffer circuit will protect the outputs to the gates of the mosfets.
Use 12 volts and square wave pulses to switch the mosfets in turn.  A variable 0-15volt power supply would be best.

The small transformers need to be of the correct size.
The input windings need to be tightly wound on a core and for 12volts 74turns are required (1volt/5.5turns at 50Hz) add 10%. They need to be center tapped therefore 148turns.
The output windings also need to be center tapped but only 70 turns are necessary. 

The core will have to be worked out

I am going to build a new model, and will post pictures.

Hi,

There are two conditions, the increase and decrease in current in alternate i/p o/p circuits and then the voltage cycle. The current cycle potentially draws a lot of current because only wire resistance is seen. The currents are less when there is flux in the core but it takes voltage to assist in driving down the flux to get maximum current, these currents cross over and then the flux builds up as the currents decrease.
I was going to post a picture of all the transformers etc in the project but there is a lot to do to build everything necessary. For a first try it is too much for you I would say.



What is required is some lamination steel and bobbins. Small transformers, about 70mm across the top. 1mm or 0.8mm wire is good for a few amps it depends how much voltage is made. 2amps x 240volt is 480watt.

Build a two winding transformer with 15% difference in turns  90, 110 with a gap, build another without a gap with 30, 34 turns.
Join the 90,110 at one end and connect the 30 to 110 and 34 to 90. Connect Positive to the join 90,110 and in two separate circuits pulse the 30 and 34 together but turn the 30 off first.
Put a diode and a capacitor in the circuit and collect the reverse current and voltage. Those windings in both transformers will now have voltage across them. 

Place a diode and capacitor in the other circuit as well. The instant the mosfet is switched off close to the same voltage will appear on these windings as well. 

The only thing missing is the current flowing in a circle and this is where a pulse can increase the output. It must be switched ON immediately, instantly, the other last mosfet is switched OFF.

It has to be a floating supply therefore it will need a small transformer where the pulse is on the input to drive the current in a circle through the output.
The voltage of back EMF in one set of windings is almost the same as the output voltage and it does not actually take much to over come this and drive a current in a circle through different ampere turns to produce high current with high voltage.  Volts x amps makes Watts. 
This setup will still produce a good output.

My brother, your time is greatly appreciated for all that information that you have shared.

There is definitely a lot of work that need to be done, that's why not everybody has this in their hands. But it is more difficult to get a person willing to share his knowledge, efforts and patience with others, it is appreciated.

Ok, let's get to work, let me see that I will be able to use whatever I have in hand and the rest; online will be bought God willing. It will take a little of time but I can put pic of how I'm going.
