All,

After trying many schemes, the parallel charge series discharge scheme with an added shunt cap across the source transformer secondary, appears to provide the correct conditions.

The switching does not have a gap between charge and discharge  so the waveforms are not exactly the same as the Babcock Murray ppt presentation. My setup is in a different configuration at the moment, so I will have to make changes again to try this out.

All,

After experimenting with various schemes, I eventually came up with a charge push scheme that uses an additional 115V (but even better results with 230V) winding, to supply an in phase half sine push to the cap after charging. This allows the cap to discharge just after the peak of the half sine and allows an average return power equal to the average forward power through the load. The attached were taken using dual 115V windings. The attached shows 1.58W average power (differential) from source and  8.07W average in load.

Use of a 230V push winding allows larger caps to be used for example 150uF, and the best achieve with the scheme so far is about 30W averag in load for 4W average source power (differential).

All,

Attached is a shot of the load voltage/current and power measurements for the latest trasnformer setup with a 230V push winding. The discharge waveform now has almost equal area as the charge waveform. A further improvement might be to phase shift the push sine slightly, so the peak is on the charge sine falling edge. This would reduce the fall off on the discharge pulse trailing edge.

All,

The 26W load average shown in the previous post is being supported by 42.5W average on the primary. The cap charge and discharge with push is clearly seen as forward power on the primary, with no sign of any power return.

The unloaded transformer draw is about 2.5W

On the secondaries the charge/discharge power averages to 3W or so over the two half cycles.


It remains to be seen if the return power truely manifests as negative torque on a generator.

Hi Barry,


excellent work. I'm working on the generator side of things, but am waiting for a new one to do some better testing with it.
