Hi Void,

I have added the transformer to the circuit, so it should be clear now.

Hi TinselKoala,

Attached are scope shots of shunt monitored current versus clamp monitored current and shunt monitored current against voltage.

As you can see, my current clamp does not skew phase.

Hi Tinselkoala,

I stand corrected, I made the check on the current clamp at your request not Farmhand.

Thanks. I have deleted my previous post so as not to confuse anyone
with the wrong switching/cap arrangement.
All the best...

All,

Not wishing to mislead anyone, I discovered that I had my voltage probe across the switches,  instead on the source input. Just forgot to put it back after looking at transients across switches!

Having corrected the monitoring I changed the 6uF cap to 4uF to get the greatest V & I phase shift. The best I could achieve was approx 60 deg.

Looking at ratios not absolute measurements, for the source I have about 52.8W forward and 37.6W reverse (peak). The average power is 7.03W

For the load the average power is 6.21W 

So I have not got close to replicating the Babcock Murray results yet.

Attached are a new set of scope shots which now correcty show the best I have been able to achieve.

3.21W average input for 2.84W average in the load.

V & I phase 72deg.

Cap is 4uF and this restricts the forward and reverse current considerably. Increasing value increases power in load but reduces V & I phase shift and hence reactive power.

Not sure that this arrangement will achieve a PF close to zero.
