Title: The switch killer
Post by: Login to see usernames on August 22, 2012, 18:55:15 pm
I'm the switch killer  ;D

I found why i killed so many in this long way... I never actually knew what was really going on.

On short,

What happens is that when the primary coil of a transformer is switched on and than off, the polarity reverses and so it sums with the source voltage to charge the capacitance of the switch... if normal operation where maximum power transfer is the objective the rating of the transistor should be at least twice the voltage of the source.

But when you pulse the primary with Dc and than don't use all or most the power you are pulsing into it will appear on the primary as a high voltage summing forces with the sources voltage to destroy the switch.

There are means for snubbing this pulse that destroy the equipment, this is well known as snubbers, they provide a way to that high voltage power to be dissipated in a resistor at a lower voltage since a capacitor absorbed this power before. 

This limits the collapsing time.

As the faster is the collapse the higher the voltage generated, to effectively have a ultra high speed collapsing time would require little to no protection on the switch, nor across the primary for sake of clarity

But how to do this and don't kill the switch?

How many can we add in series? 10? 20? 30? ...?

It just takes some work and money...

The solution i found to be varistors. They are like zener diodes but are more powerful, there are other solutions however. but the idea is to create a system where the transformer magnetic field developed during pulse on, collapses as fast as it can as the switch turns of to reach the highest voltage possible. But how to make it controlled? I was trying with resistors but was a mess i keep burning...

 Well using varistors since they will clamp the voltage to a maximum set for the switch being used. Now the mosfets can run heavy inductive loads happy.

Now for saying i'm working on 0-100v  range for the primary with a T factor of 50 and allowing the voltage to grow up to 10x more than 100v

So 50kv within up to 5000 turns... primary with 100 turns...  so one volt per turn to 10 volt per turn during collapse since its limited by the varistors...

Actually another solution could be a non-dissipative snubber having a varistor to protect only the over voltages... a snubber winding is required however


I think i found a good solution for clamping the voltage of the transformer,

Using a 100v dc source with a capacitor in parallel for example you get two winding the primary and the clamp winding and a diode.

The primary is connected as usual, but the clamp winding is connected from ground to the positive thru a diode reverse biased...
When the switch turns off the voltage across the primary is not allowed to grow to infinity since the clamp coil will return the energy to the input circuit limiting the output voltage with little power consumed.

The secret to allow the field to collapse is to have a snubber coil smaller than the input coil by the factor of voltage amplification during pulse off time condition desired.

Of course snubbers and other surge protection is still required but theres never perfect coupling and theres also leakage inductance but  power dissipation on this will be minimal if the circuit is well designed.

Since the input capacitors are generally big they can re store lot of power with no problem...

I think i see why meyer wanted a big diode in the circuit check the attachment...

This circuit is design to be able to give voltage regulation of up to 5 % if current is up to 2A, this mean that when the field collapses the source will receive back a short burst of amps and as the capacitor is already charged the discharge becomes very fast.

So in the end the energy is sent to the coil and the energy that was not used by the secondary return to the capacitor as a small ripple.

Circuit example, primary 100 turns 100v applied 10khz

If the transistor handles 1200v than you can allow the 100v to be increased by a factor of 12, but lets assume 10 for safety so the clamp coil should have 10 turns... As theres 10 x factor of transformation the amps in this coil are 10x greater so if you are using 5 amps in the primary on the clamp coil there must be 50 amps so the diode must sit on a heat dissipation metal. Of course the amps are very fast not really continuos thus the power dissipation is not very very high... however.

Now if the input capacitor is big like 100miliFaradays than it can handles more amps without much ripple.

the clamp coil return the energy to this input capacitor basically and since its always charged from the 100v source the voltage will vary within a certain amount, the ripple.

So your goal is to re-use some lost energy?

Basically is just a way to dump lot of energy in the coils, and if its not used its just recycled like in resonance. This recycling clamp protects the circuit and limits the output voltage to a safe level for the switch. Is basically a non dissipative snubber so it simply don't waste too much energy like using only varistors and dissipative snubbers of any kind.

The input power in this way will probably be little lower than the power being pulsed because of this resonant like carachteristic

The important is to have the big capacitance in the source sequence,,,  This is the energy reservoir...

I Found on simulation that maybe 10mf could be enough

In dan danfor circuit also there is a 10mf capacitor...

Later i found that 1mf capacitor charges faster and can be a cheaper solution, the higher the better however because the circuit is more stable... and it will have a lower esr...

Using the snuber capacitor in the regenerative configuration proposed on the paper generate a back positive spike on the primary coil since the snubber will be charged to 1000 volts thereto a diode can be added and the relation of primary to snubber winding is 9 the voltage across the primary should be if circuit is not loaded 9kv for a very brief moment, on simulation is don't arrive at 3kv  for a 20nf capacitor.......

Question?

What happens when the coefficient of resistance is greater than the inductance? in a coil for example?

I'm imagining from the point of view of the flux... For example if the linear induction is 5 amps the voltage across the coils could be reverse if too much resistance in it?

 Let me try again...

I mean if the resistance of the coil is so great that the amps being induced into it create a counter voltage that is bigger than the induced voltage becoming a net voltage ...

For example of what i'm thinking if you had a 10kv 100ma transformer and its discharged into the coils resistance being it a high resitance what happens ? What if the coils had 100kohms? Whats physically happening?

I don't know is just a reflection...

I'm wondering why in hell meyer mentioned stainless steel coils.. . It still making no sense for me!

I'm thinking on the possibility that stainless steel being resistive the electrons must flow faster into it than they do in copper... what if barbats technology about low mass electrons is related to this?

Maybe this material also amplify the inductive energy photons....

????

More questions than answers ...

but i guess that if we simply analyze the first idea i was maybe wrong in putting the amps in front of the equation because the amps only flows when theres voltage and a closed circuit for them to go...

If short a resistive winding having 100kohms resistance and zero reactance (for sake of example) and we apply inductively 10kv than 100ma flows thru it, thereto a ohmic voltage is developed over the circuit....

so no magic at first glance. 

Maybe the secrete is how this stainless steel material ferrimagnetic interacts with the fields of the primary coil since its itself magnetic.


This circuit for collapsing fields is very interesting, i think i understood the idea behind those free energy ( thinkers) that believe bemf is the solution... like bedini...

The idea that a field can be collapsed really fast is already there but what if you just take this and apply to motors?

Imagine a motor having permanent magnet stationary north and south

Theres a brush and the coils inside the motor

The known operation of a dc motor is that you apply a voltage and when its rotating fast the BEMF induced by the motion opposes the applied voltage thereto restricting the current that flows. If you try to stop the motor or add a mechanic load to it the speed is lowered so as the BEMF and the current increase with the increase in power furnished by the motor.

This BEMF is related to the fact that the rotating coil is acting as a generator. And it do so because the basic brush motors has only one collector brush system so magnetic field must be reversed in the coils each half turn of the motor..

Tesla first but UFOPOLITICS show a way to use two collector brush systems that allows the magnetic field in the coils to never completely reverse. Basically each coil receives only unipolar pulses because of this arrangement. So the BEMF is not a such big problem here... It acts as a generator in the opposite directions using the bemf to increase the current and thereto the force of the motor.. It works very well.. though

I started writing this ideas to think so keep going....

What if you can take a sistem like steorn motor and use the magnetic field to attract the magnet than collapsing of the fields as a way to reset the magnetic field at the point which the magnet is closer to the coil than transfering this energy to a capacitor and bang it back with reversed magnetic field to push pull the motor...

for me the error of major types of experiments is that they didn't knew that they can instead of sending the charge back to the battery with lots of losses they could send the energy residual from the bemf to a capacitor and charge it fastly to high voltage with snubber winding just like on the schematic i'm going to present soon...

Basically when you discharge back this capacitor the current reverses as fast as it has discharged during the collapse! and from that the battery keeps going on on full amps and pick it little further after the capacitor has discharged,.,,

with a tertiary snubber coil the power can get back to the circuit from the capacitor discharge if desirable, this will save the diode that isolate the primary from the dc...

I just developed another snubber circuit that is non dissipative and it makes the frequency to be multiplied by 1.5 at the resonant frequency... basically it triplicates the pulses... thats because i add a capacitor between drain and source of the switch and a capacitor between the primary positive side and ground, this makes a resonant circuit that when the switch open the coil discharge into the snubber capacitor, than when its fully charged say 1000 v it discharges thru the coil generating a yet higher pulse charging up the other capacitor.

first pulse on first pulse
turn off collapse pulse
capacitor discharge into another thru coil another pulse
than turn on again and a bigger pulse because the capacitor gets charged higher than the source voltage.

If the capacitance is reduced by a factor of 100 than you get 100x increase in energy.... All it consumes is heat,,,, This certainly mean over unity possibility.

If you consider the mass of the capacitor very small the energy input will be equal to the initial charge + the heat...

Why don't we use this concept for nuclear plants?

I'm thinking that if we could have a material that is both magnetic and dielectric forming a capacitor and at same time the nucleus of a transformer. Than if the electric field increase the magnetic permitivity and conversely if the magnetic field increase the dielectric permitivity... Energy could be generated forever. Probably the prototype would blow up because no proper load attached to it.. .

This would require that this material is made up on laminates and that this laminates must be metalized to form a stack of paralel capacitors ....The capacitor is connected in parallel with a coil wound around itself, so when the current is max the capacitance is max so more charge enter easily later the magnetic field reduce and the capacitance decrease raising the energy which is than discharged back to the coil but at this point the inductance is decreased too thereto increasing the speed of the discharge.... and so on...

that's nice 8) but if the inductance is decreasing the max magnetic field stored in the inductor decreases and the max change in the dielectric permitivity decreases so the system will stop function or am I saying smthing wrong?there are materials that are dielectric and magnetic..Fe3O4 but how will this work ?
Title: Re: The switch killer
Post by: Login to see usernames on November 22, 2013, 10:56:08 am
If you consider that the circuit is a lc parallel resonant circuit you have that when the capacitor is charged E field max the inductance must be small so to have ability to charge the coil with max current. The smaller is the reactance the greater the current thus the greater is the energy going in there. When the capacitor is fully discharge the inductance now is a maximum and the amps are discharged at a greater energy level but now that the magnetic field is high the dielectric must be maximum too so it can discharge more current into the capacitor when the magnetic field is vanishing the dielectric constant again become smaller increasing the energy of the charge in the cap.

It needs a small gain per cycle to  become self sustained oscillation because it gains in both ways. at twice the frequency rate.

Seems a good idea to you?

To make a such material with both ways gain may be hard but maybe to make a one way could be far easier..

Post by: Login to see usernames on November 22, 2013, 22:58:01 pm
it seems very interesting here are a few thoughts

After a while the system will stop because the dependance of these parameters is not linear so it needs a proper load to keep it generating if it works and there is extra energy stored both in the coil and the capacitor

U=Uc+Ul=q^2/(2*L*I*σ*κ*C) +μ0*μ*N^2*A*I^2/2d

σ is a constant that increases the dielectric constant because I couldnt find a btter approximation

I just thought of something remember that multipactor device that shoots electrons back and forth , if you make it so the plasma ions between the capacitor plates don't touch each other and just go back and forth .Because the ions are aligned according to the electric field the dielectric constant of the device is changed so the energy is changed and because the ions don't hit the plates no work is being done except that the energy is increased of decreased depending on the alignment of the ions. might be possible... but with super fast electronics .  when the plates are switched you can get energy out of the capacitor but there's only nanoseconds to do that .

The multipacting effect is related to the multiplication of electrons so far as i understand, when they hit the plates they knock off 1 or more electrons but when do so they start to accumulate ever increasing the energy inside and ends up burning the device.

I think i understood the electron extraction circuit of meyer.  it must be a vacuum tube with a hot filament and this electrons should go to ground or wherever you may want them. Or could be an air ionizer, simply something that allow the charge to goes aways mechanically or electronically. 

When generating the gas is concerned the idea is that when the ions get absorbed by the ss plates by the actions of fields they react exchanging their charge with the plates, donating or receiving an electron, at this point hydrogen is in the matrix of the conductive medium but to release it it must effectively exchange electrons to neutralize the charge but what if you neutralize the charge without allowing all the electrons to go thru, by burning them off>? the charge remains to the water or the gas and must come out as ionized gas !

All this discharge happens at the gate time, after receiving many positive pulses the high voltage insulated plates receive opposite polarity pulse or simply shorts the plates to force the ions desorbed to discharge their electricity at a voltage determined by the circuit arrangement.

This mean that probably electricity can be generated in large amounts allowing it to be self sustaining generator.

Is another type of gas i guess.

I'm mixing the concepts of many patents, together they fit.

tay hee han, and all cited documents and whatever patents that made citation to it and for each.

Including meyer concept of bifilar coils and pulsing, gating and field collapse concepts. 

I don't know if i'm right but it seems to me that summing all the stuff i learned meyer technology don't seem soo strange at all. he just hidden everything just in the face of everyone. He designed it to fool.
Title: Bifilar coils
Post by: Login to see usernames on December 07, 2013, 16:52:47 pm
Let me talk again about bifilar coils

First of all the electric field in coils is a point of concern

After all thats its major value to water for fuel technologies

Its ability to replicate the same voltage impressed on one another is impressive and useful if considering pulsing inductive charging...

Coils smartly reverse the voltage if magnetic field start to fall down, another major property.

A bifilar coil with a diode can do many things.

Lets say one coil is connected to two outer tubes spaced apart and the other connected to the inner tubes of two tube sets thru a diode in the same water.

Now when the pulse comes it start to charge the voltage zones but when the field reverse it forces the

have you considered actual fusion/fission of atoms? the energetic particles from nuclear reactions can split H2O easily. there's one guy that said he did just that.

about my previous post imagine of an LC circuit ,a coil wrapped around a capacitor and the cap formed like a parabola with ion emitting material on it when ion plasma develops you change the fly time , the coil keeps the ions from accelerating too much and when the voltage is flipped on the plates , the alignment of the ions changes inside the capacitor not instantaneously changing the total electric field of the capacitor that's when you can extract energy out of the system but there's little time to do that.

I'm taking about  what stan seem to have pointed as the right way of looking into it. The movement and deflection of ions and electrons in an electronic circuit.

I don't know about the need to use radioactivity to split water, after all is not totally safe. 

Stan called it a resonant cavity

Stan used a gated train of pulses (this mean it was needed for something in his design other than just control the amount of energy in).

Stan used Stainless steel and said it were a necessity for it to work and be durable

He described that the amps can be restricted (or maybe redirected) in such a manner that as they generate electricity the hydrogen gas is released. Meaning a self oscillating and self sustained oscillation can be achieved.

He describes water as a dielectric and use its proprieties to achieve gas generation

He applied up to 40kv or beyond to the system

In other aspect he start from 100v source

He uses the collapse of the magnetic field to create the high voltage needed.

He uses bifilar coils

he used more than one tube set at a time from what i see
