Rosemary Ainslie circuit demonstration on Saturday March 12th 2011

In order to begin a detailed analysis of the circuit we're discussing, I created a slightly more detailed version of the schematic diagram, as attached in the pdf file.

I increased the battery wire inductance to 3.3uH as requested, and I've separated the lumped wire inductance and resistance out to 3 segments as shown. Electrically, this is equivalent, but allows for flexibility in the measurements and analysis.

The same was done for the batteries and wire jumpers, as shown. I approximated each wire jumper to be about 20 inches in length, each with an inherent inductance of 20nH per inch, hence the 400nH per jumper.

Remember that the resistors and inductors shown representing the RED and BLACK battery wires are not physical discrete components; they are used to represent hidden but inherent values as a consequence of finite wire resistance and parasitic inductance.

Hopefully the labeling is clear and it can be agreed upon that this represents a good starting point for the detailed analysis to follow.

The first entry here is of the schematic ONLY. Scope shots etc. to follow if this diagram is acceptable.

Hi Guys,

By Monday I should have sent out the mail shot to most of the English Universities to look at the sims for themselves. 

I'll let you know what the response is as they come in.  I shall be doing the same the American universities soon thereafter. 

I'll also be submitting our paper to the IEEE within the near future.  I'll keep you all posted.

Kind regards,
Rosemary

The first scope shots establish a baseline measurement of results similar to previous posts.

With the added inductances, the measurements are slightly different, but still show the apparent negative power to the battery. The net average power for the baseline measurement (scope probes in the positions noted) is about -106W.

The relevant nodes in the circuit have been numbered 1 through 7. A notation of V3-2 (VCSR) means the voltage across nodes 3 and 2 with the polarity + and - respectively. V7-4 (VBAT) is the baseline battery voltage measurement.

I just wanted to take this opportunity to say that I think that Darren (Poynt) has gone out of his way with these PSpice simulations, something he did not have to do.  I, for one, appreciate his efforts as I know they take time, a lot of time.  Thank you Darren for dedicating your time to do this.
