Reactive power - Reactive Generator research from GotoLuc - discussion thread

Luc,

Despite a lower power output with the capacitor experiment I asked you to perform, you were still able to show a negative mean power.

The current is inverted because the return path for the smps transformer primary bypasses your 1 Ohm CSR. If you try that experiment again but connect the return to the CSR rather than ground, you should see the current wave form reverse phase. Don't use a scope probe on the output bulb though, as it may wreak havoc on the measurement.

Hi poynt,

Would like to understand what you suggest to connect exactly what to where and the best would be if you could modify your schematic and show it. 

I attempted to modify your schematic as I guess you suggested but I am not sure my drawing reflects correctly your suggestion, see below.

Thanks,  Gyula

Gyula,

I am at work and don't have my Visio drawing to show you.

However, if you take my last drawing which shows that CMM capacitor connected between the primary and ground, simply connect it to the right side of the CSR (at P2) instead of ground. Now all the current goes through the CSR and it is not bypassed.

You could also install the CSR right under the FG negative terminal (in series with the negative lead), and that would work as well, but this time one would not need to invert the signal on the scope, because the probe placement would not be inverted. Also, CMM would be connected between the primary and ground once again as shown in the diagram.

Well,  I have just modified the drawing as per your first suggestion above and I replaced my previous (wrong) modification to this new description, see the attachment in my previous post. Is that correct now?

[poynt99]

Yes, looks correct.

Hi poynt99,

Thanks and in the meantime I edited your drawing to show your other suggestion on the placement of the CS resistor, in the 'negative' lead of the signal generator, see the attached file.  Is this also correct as you described?
