rotoverter for power generation

[hanker886]

Thanks Ash,

I did notice you are also on yahoo. I'll look in to the places you suggested. I have been spending a great deal of time on TPU threads. It is exciting to see TPU threads thrive and grow. I think it's a matter of time before we, guys on OU, crack the codes.

I didn't get as much power as I'd hoped but..............................

WE HAVE OVERUNITY OUTSIDE OF THE GENERATOR

I used an old cooktop with all four burners on maximum for the load (7.6kw @ 240VAC on the label).  Here are the particulars:

PM:  5.5 amps @ 120VAC = 660 watts in

Alternator:  5.22 amps @ 274VAC = 1430 watts out

It's only taken 20 years!

Hi Rich,

Congratulations!

Would you share some more details?  I don't  get how and where you used the cooktop burner as a load? You loaded the alternator with it?

Thanks,

Yes, the stovetop is the load.  I placed the load in series with the cap bank and wired a switch to short-out the load while building power (charging the cap bank).  Once the cap bank is charged then you open the switch and this forces the charge through the load.  The power is very stable with no problems of maintaining it for long periods.

Hi Rich,

Thanks, now I understand, very good idea to connect the load INSIDE the parallel resonant circuit created by the alternator's windings and the cap bank.  The reactive current inside the parallel resonant circuit is what flows through the load.  Now if you had an alternator with very low winding/copper resistance, your ou results would be even better, right?  (part of the output power suffers copper loss, unavoidable)

If you switch on or off or control some of the burners out of the four, does the output voltage change a lot or a little? And do you have to retune a little bit the RVed motor (the prime mover) when you change the load?

Thanks
Gyula
