Pulsed DC Transformer with Embedded Magnets

[spinn_MP]

How about measuring the momentary I and V values at, say, 1ns, then multiplying each momentary I by the corresponding Momentary V and then finding the average of these products. Thic you can do for the input I and V and compare it with the output I and V? You probably still have the traces in your DSO's. If so, that calculation won't take you long and you may report it here.

Hey retard (OmniBot, not Lawrence...)
How about measuring the thing with one of the more conventional electrotechnical methods, like "any method non involving the procedures you personally don't know shit about"?

What a cook!

They cannot even measure if the thing put's out more then it consumes HAHAHAHA!!!
Way to go Lawrence!!

PhysicsProf,

Thanks for the update, I (and I'm sure others) really appreciate it.

My colleague and I spent about five hours studying Prototype A on Saturday 1/1/11. 
We had previously spent some time studying it after we received it from you.  (Thank you!) 
Certainly if one calculates the COP using either PP or RMS values, one derives COP > 1, as you said.

But the large discrepancy between the PP and RMS values gives rise to concern, as to whether either approach is truly a valid measure of the COP.
The fact that the output signal is far from sinusoidal also gives us reason to question the use of V*I (from PP and RMS values) to determine power.

So we replaced your two resistors on the output with one resistor and then performed tests based  the heat generated in this output-circuit resistor. 
We had one thermocouple + meter system available and so we did a balance a piece at a time. 
We found that we could match the heating of the output resistor from the DUT with 0.04 Watts of power over the same resistor from our battery+variable resistor
(which substituted for our power supply). 
The thermocouple was taped to the resistor for these tests.
It took some time for us to home in on the matching input power... but we feel the calibration of the resistor is believable.
However, this method is still very approximate as it does not account for heat generated in the diode/LED. 
It is a first-order check on the method of measuring COP from PP and rms values as you have described.

  It is interesting that this value for the output power, using the thermocouple-balance measurement,
is BETWEEN the simple V*I calculations (PP and RMS) I derived from Prototype A,
which gives about 0.39W (using PP values) and 0.027W (using RMS values for input and output).

So a firm conclusion is that we need something better than just simple oscilloscope values and V*I...  as we all apparently suspected.
You also noted that it would be important to integrate the oscilloscope traces (input and output) to get a more reliable value for the COP -- that is yet another method. 
Have you done this yet?

-->  So I feel that our studies here are just beginning on Prototype A (and variations), but our studies are certainly encouraging. <--

Best wishes,
PhysicsProfessor
