COP 20.00 (2000%) Times, Reactive Power Energy Source Generator,

[listener191]

I can apply average measurements to the V&I displayed however, I have not found a way to apply an average to the Math function AXB, so I only have the peak power values. This DS1104Z is a new scope for me, so if anyone knows how this may be done, please let me know.

Attached are some results from a single cap variant.

Note: the Rigol scope has bug in the way it handles units for Math functions. In this case it uses the Amps units set on channel 1 unless I change channel 1 units to Watts.
The calculation of (VXA) is appears to be correct.

Anyway power is the main concern for measurement. The scale for power is 20W per division. The source display is showing two divisions forward and one division reverse power. The zero line indicted by the bottom of the switches off period.

The load display shows V & I pretty much in phase and one division of power.

These shots are with a 6uF cap replacing a 4uF.

I have opened the switching dead period so the zero line can be clearly determined.

The source shot appears to show almost equal power being returned to the source. The source power measurements show an average close to zero, max 30W min -30W.

The load is showing 16W average.

I repeated one of the load shots. This is the one I should have uploaded.

Hi Listener191. You are doing excellent work on this. Those are really interesting results. Because there have been so many
ideas and possible capacitor and switching arrangements discussed, I am not clear on what switching
arrangement and switching timing you are currently using. Would it be possible for you to upload a 
simplified wiring diagram showing how the caps and switches are arranged in your current setup,
and what your current switch firing sequence is with that arrangement. Only if you have time of course.
I am having a hard time visualizing this...
