in all likelihood the difference will be in the output part, maybe in addition to the LC filter you'll need a suitable mid-point step-up transformer, and the outputs to be switched [perhaps via a relay] in audio and inverter modes

I understand from those posts that an AC step up inverter may be used instead of a transformer? This may be, but i don't know if the popular switching supply modules would work. They have different frequency than 50Hz. They work above 8kHz. Thus this should be something more original like STEP UP 9V-230V AC/AC Inverter (available?). Also I understand your claim that the amplifier may work in "Impulse" mode I proposed in my handbook. With bigger caps in supply this is possible, but I think it does not make much sense if Paulos is stable and to boost power you may add motor with magnets near transformer or use Modo on phase output or even combine with this caplos.

Only to check if it would eventually work, you can try with this https://pl.aliexpress.com/item/1005004942381316.html straightening first the voltage by bridge rectifier and add a cap, but i can see the wrong freq. issue... Maybe for switching supply powered amplifier this may be better... many questions...

More info on Modo:

I think using 3-5 ohm/50W on input may protect the circuit. Messing with audio input may change the overall effectivity.

Glad to know you are still working on this gizmo, just waiting for the video which shows device in action.

Hi,

I've been thinking more about this version with inverter. In my opinion a transformer is simple and good solution. It works well with low frequencies. The energy gathers in this place between transformers, so you may get more than 500W between devices of overall lower power. Even using 10W transformer and 50W main trafo will give good effect.

But using inverter may be good for switching supplied devices and some of the amplifiers utilize this like home cinema players with speakers included. My only proposition here would be sth not like AC-DC-AC converter but dismantling existing inverter and driving it from an amplifier channel tuned to specified frequency in range of 8-25 kHz. This may give some savings in inverting voltage.

Good amplifier has real efficiency of about 110-120% (input vs. output). Giving good inverter to this may easily loop, but don't forget about noplis trick and utilizing right channel.

Also this version with fat coil works well with voltages like 20V 1kHz sawtooth, and amplifier gives only 6-9V unmodified. You may try this coil only with special supply and driver. May close the loop.

Here is the proposed schematic. I don't know how to make driver, but 3-4 transistors should give effect.

Also, when voltage doubler used or bridge rectifier with electrolytic cap, I was wounding a little noplis on it taken from the output of a fat coil. This can boost energy efficiency, especially on higher voltages as proposed in the last schematic.

If you don't know how to make a driver, just use 555 in sawtooth mode (use 78L05 for this circuit, freq. is regulated by capacitance)

and voltage follower based on a transistor (emitter follower) supplied with 25V, play with resistors:

Thanks to all that donate. I won't stop informing people about free energy systems. We can change situation worldwide and also save old electronic components from recycling. I had Jawik like system that holds even 100V, feeling sorry for my fault I proposed sth solid state that can really work :).

If you have old crt tv or monitor, reuse the cable around the screen and make a coil. Thus you can have this solid state. If you once start such system, you may start from it an amplifier like from a battery :).

I think the easiest way would be using a simple near sawtooth gen on 3 transistors. If voltage doubler is not that efficient, look at this video, i think it's interesting method of rectifying and you have another pin gnd to utilize...

Here is the info how to achieve voltage only from junk parts. The urgent values are given. You can then connect chains of right voltage parallel to achieve more power (current). If you still have spare time and don't know anything, this may work for You :).

Just thinking about extrasync that I was connecting in 1991. That may be sth like this. I was using up to three transistors with resistors. I don't know if the EBC connection is right. Rather Emitter goes to minus, i can hardly remember. Closing loop should be still placed. This is just a thought. You may try to expand this and use your own version.

Very happy with the community :-).

@dxer_87

<joke>Are you from Dallas? Because your posted image is "bigger than texas" ;D </joke>

Thanks for sharing that information.

Best of wishes.

I was fighting whole night with my smartphone to achieve this image uploaded. In the morning I made factory reset. Also reinstalled os on the laptop...

Hehe, Poland is a friendly country. I come from a small village. I do believe this makes sense and after some tunes may give extra current into the system, so bigger transformer can be used, without impedance restrictions.

I made an image:

I can hardly remember I was adding here a little transformer also, search for 'Joule Thief schematic'. This should be sth like in this circuit. I don't know the parametres of transformer, but may be the one from AC filter would work, but the one with more turns on its windings.
