Here is my first test of the AliGen.

http://youtu.be/zI9xTK-hXO4

Component differences as noted in the video:
1. I am using IRFP260MPBF instead of the IRFP260.
2. A 17.4uF cap instead of the 18uF
3. I've added a FEP26JT diode pair as snubbers across the source/drain.
4. A 1mH choke is in series with the sig gen ground.

The Inductor was initially set to 377uH and then slightly tuned so that the LC circuit was resonant at 2KHz.

In my setup the peaks are located at the leading edge of the square wave pulses , whereas in Ali's sims the peaks are located at the trailing edge. I find this strange. I don't know what has caused it, unless perhaps the choke has caused the shift - I'll have to check it.

Duff Why not change out the 90s with tees so you can adjust the ferrite on the fly, by reaching through the tees with a push stick?

The ferrite rods only extend 19mm out the end of the horizontal piece so I still would not be able to adjust them.
Maybe I'll make wood end pieces.

Thanks for the suggestion.

@Mags
Thanks

@Duff
Thumbs up.
I will suggest, just give it a try by removing 1mH in series with sig gen to ground and place a 1H inductor in series after 4700uF cap to ground. and see the strange effect. I told u this circuit is really a weird one once it started running by itself on my table. But it is definitely producing harmful radiation also. My two external HDDs were wiped off which were placed 5 meters away from the toroid. If u feel something strange later while walking or working on laptop, some off center visions, don't panic. Its just effecting your bio energy field. To be at safer side I prefer just to use some Al shield box . I am not a psychopath but strange events have been happening since then I conducted this experiment and I am astonished why it is so? Am I fiddling with secrets of nature?

Hi Ali,

I will try your suggestions but it may be a few days before I can get to it because I have to order more MOSFETS.

Also, I guess I need to move my laptop out of this room - I don't want to loose any data.

I was testing again this morning and when I connected the battery to the circuit, as I have many times before, smoke started barrelling off the 4700uF/63V capacitor. I didn't really look closely at it - too busy trying to make the disconnect.

Well, the capacitor checked out OK but the MOSFETS are blown. They were 50A MOSFETS...
In addition some how the signal generator square wave function was also damaged.

I'm still scratching my head on this one as to what happened.

Thanks for the suggestions & warnings.

I hope ur sig gen was not connected with 4700uF. and if not then definitely ur 1mH damaged ur sig gen. coz it gives a kick off of high voltage back to the source producing pulses.

This topic has come to my attention and I can provide some insight into the operation of this circuit. I simulated it with LTspice as can be seen below.

My primary comment is that this circuit is primarily a modified BOOST converter topology, lacking only the diode and perhaps the output smoothing capacitor. The parallel capacitance of the coil is always present with any real coil, and perhaps this capacitance is enhanced on purpose by Ali. Due to proper timing and resonance, the switching occurs at zero voltage (correction, at zero current technicaly which is very efficient), so it wastes very little power in the switching phase. Here's a link if you're interested: http://en.wikipedia.org/wiki/Boost_converter

The real question is: where is the power coming from?

The answer is: the power comes from the 50 V supply, wheater it is a battery, or a large capacitor, or a power supply.

I'm wondering, do we have a claim here that using a capacitor, the circuit runs indefinitely and the capacitor stays charged up? If that's the case then this would be very significant!

EM

PS. The blue curve in my simulation is the current defined positive into the (+) terminal of the power supply V1, so when we see the negative ramp down while the switch is on, that's when the inductor is charging up magneticaly and current is increasing according to dI/dt = V/L approximately, and upon switch off, the inductor supplies it's energy to the load producing the kick-back. The red spikes are the kickback voltage across the load resistor coming from the inductor. However, due to capacitance in the circuit the inductor reverses polarity and the voltage drops down to zero, and that's when we switch, so this circuit is operated in the zero voltage switching mode (corection, it is switched at zero current see the blue curve), which is very efficient. If we do not waste a lot of energy from the input power source (V1 in this case) we can replace it with a capacitor and have it seemingly run by itself, but the energy in the capacitor will deplete over time, much like the Joule Thief circuits.

And it still WILL BE OU! It only need to run at 50V level long enough , much longer then initial time used to charge capacitor. What is your simulation showing after a hour or two (simulated)?

EM,

You need to replace V1 with a 4700u capacitor, charged to 50V. Then run the simulation; if the oscillation persists, then you have replicated Ali's simulation. If it "falls off" as it did in my simulation, then you are at the same point I am at right now.

Still waiting for Ali to upload a working PSpice version, OR a video showing his bench build oscillating indefinitely.

EM,

That is the claim.

This is my simulation with a capacitor, and of course we note the voltage drops as the energy is drained from it, just as expected.

(I was even conservative and only added 0.5 ohms of resistance to the inductor, if I have zero ohms resistance, the discharge rate is obviously slower.)

If Ali claims his capacitor does not drain in his actual built circuit, then it is likely the 5 volt square wave pumps the circuit through the capacitance in the MOSFET. In that case, the power is realy coming from the 5 volt square wave switching signal. But I have doubts on this, because the obvious source of power is the main capacitor, and he is only showing a simulation of a few miliseconds.

It is still a mystery as to how his MS simulation lasts for so long. In mine the oscillation starts falling off after about 20ms. I used NO coil resistance.

So you are about where I am now. Someone early in this discussion mentioned that "it did not work in LT Spice", and I get the feeling it does not work in PSpice either. That's why Ali has not posted working files for either.

He does claim that he has a working unit on his bench. However, we've not yet seen evidence of this claim.

This is what I mean by driving the load from the 5 volt switching waveform, see simulation.

This is as simple as it gets!

It works becouse the MOSFET has internal capacitance between its terminals. To somebody who is not familiar with electronics at this level, they might think this is over unity, but it's not. The energy dissipated by the resistor comes from the 5 volt switching waveform, and even though the GATE is insulated, and no DC power flows, AC power flows quite nicely through the MOSFET capacitance.

Now, I'm wondering if ALI has the circuit tuned just right so the 5 volt waveform pumps the tank circuit and keeps the charge on the main capacitor. In that case, he needs to scrutinize in more detail the power consumption of the 5 volt supply.

Hey Em

In your schematic above(shown below edit. actually the next post) I dont see the diode on the mosfet. I played with this circuit in Circuit sim, using the analog switch in place of the fet and the added diode gave much better oscillation. Dont know if that means much. ;]
