Self-sustaining parametric device

[Dexter2025]

This is the theory of a parametric device I build in success and share with you my results,  I will share more soon

Great, I look forward to more info

Good job, do you have any videos of the device ?

[Dexter2025]

Now videos

This videos show 1KW device generate 220VAC, 50 Hz, by using 2 transformers of 500VA each and Arduino for load control

Hello Dexter2025,

Thank you for the videos.

Could you please draw schematic of your device ?

and show power rating for the load lamp you are using.

Thank you.

Hello Dexter, is it possible to power also inductive loads or electronic appliances? If yes, where should be placed the load in your circuit? (in series with LC elements ?)

Thank you for answering

Yes, you can put inductive loads, the coil in series with the resistance in that circuit can be a transformer with the load at the secondary coil

Hello Dexter2025,

thanks for the excellent document and the build. I am slowly getting into it. But I wanted to ask, you just wrote in the previous message that you can put something on the secondary of the inductance in the circuit. But that will change the Q of the resonant circuit, because it will change the "stored energy" that oscillates, won't that decrease the performance of the circuit? Possibly even extinguishing the oscillation?

I am asking because I made a series resonant circuit with a transformer and I have quite some gain on the primary, when I attach load on the secondary, the gain decreases because the Q decreases.

Thank you very much for your contribution!

Hi Dexter2025 and all,

this is my first post on this forum, seems like most of the other forums are dead now...
  
Anyway, thank you Dexter for sharing this. It reminds me a bit of J. Murray's SERPS circuit where energy is shuttled back and forth through the load.

From what I see your setup discharges 2 pre-charged caps connected in series into a coil through a load, then the coil discharges back through the load into the caps switched in parallel. The caps switch back to series and the cycle repeats. 
The zener/opto diodes setup sense the state of the coil and series caps voltages and switch the transistors accordingly, thus it's self-regulating its frequency and length of each quarter cycle. 
Is this correct Dexter?

I may be wrong, but in fig.13 of your document there seems to be a mistake though?  Q3 with its rectifier setup should get its upper connection from below C1, not above C1, else there's a direct connection from coil to ground.

regards,
Mario
