Reactive power - Reactive Generator research from GotoLuc - discussion thread

[gotoluc]

This post is for TinMan,

I was thinking over the the battery charging of my last video and thought you are well setup to take advantage of this interesting effect since your prime mover is DC.

After I made the video for you of the meters on the exciter side of my Gen which was tuned to output the most AC on a 15 ohm load, I decided to test with a Series FWBR instead of the 15 ohm load and connect the DC side to a battery. Nothing special other than I could reduce my series cap bank to 15uf instead of 25uf. Then I decided to add a second battery in series so now I would have 24.6vdc on the 15 ohm load, now that was special since I didn't change the 15uf cap and the batteries maintained the voltage and we now have 40 watts on the load. I didn't add a third battery to see if it could keep going up since I decided to test it on the 240vac grid to see the effects and that is the last video I shared.

I would suggest you test it and see how far you can take it and who knows, maybe there will eventually be enough power to feed the prime mover. This is the goal of this research and you are well set up for it now.

I'm also starting to think the smaller batteries not maintaining there charge maybe due to the load being above the batteries charge rate capability.

All the best with your tests

Here are two scope shots (png format saved to flash drive) illustrating the difference the channel coupling makes on the computed MEAN MATH. I only changed the CH2 (current).

First one is with CH2 on DC coupling (how it should be) yielding a positive MEAN power. Second one is with CH2 on AC coupling, yielding a negative MEAN power of almost equal amplitude.

If you save these to your hard drive, then view them in sequence, you will see that the MATH trace moves in the downward direction when going from the DC to AC coupling shots.

Here is a photo of the new parts I am using for these tests. I've only used the 10uF thus far, not the 5uF.

Weren't Luc's sample scopeshots showing both channels DC coupled? On Tek scopes I've used, there appears a little "sine wave" symbol next to the channel settings when the channel is AC-coupled, and nothing when the channel is DC coupled. Inversion is shown by the downward pointing arrow.

Poynt, your test shows the effect of AC coupling of one trace on the resultant Math trace mean. But I have a question about the effect on the mean of the original trace itself. Should an AC-coupled signal produce a "mean" value of zero, for that trace itself, before entering into the multiplication math trace?
