.99,

Did you do the temperature control for the 2.5KHz experiment,

Paul,

The CONTROL POS is 1.3W for the same TRAA. DUT POS is 2.0W.

My new Kelvin-style LCR meter has arrived, and I shall be picking it up tomorrow. I'll now be able to get precise inductance and resistance measurements. As I mentioned a couple of times, my 0.25 Ohm shunt measured to 1uH with my "cheap" inductance meter, but the lowest range is only 2mH. Will be interesting to see what the new meter measures.

Poynty - I thought you were on holiday?

I'm on vacation away from my job, but on no holiday, that's for sure (house fixin')

So you're saying only the load produced 1.3 watts worth of heat, but the scope load calculations came to 2.0 watts, right? That's one thing that seems unclear in your previous data. Example, for the 375KHz experiments you wrote "CONTROL POS for equal TRAA of 67ÂºC = 13.5W". When you write "POS", are you referring to the power supply used in the control temperature measurements, not the POS in the Ainslie circuit, right? Wouldn't it be clearer to write "CONTROL PIL TRAA of 67ÂºC = 13.5W"?

That could help increase the accuracy of the pulse measurements, but that should have no influence on the POS (power from the batteries), or the load temperature measurements.

Yesterday I made the following post, but removed it because of the uncertainty of what you meant by "CONTROL POS for equal TRAA of 67ÂºC = 13.5W" If that means the "load" in Ainslie circuit produced 13.5 watts worth of heat, then -->

"According to the scope calculations, the load produced 64.09 watts, but the temperature measurements showed 13.5 watts. That's 4.75 times off. If we take that same error for the mosfet, we get 44.27 watts / 4.75 = 9.32 watts. That is in close agreement with the predicted value of ~ 9.2 watts."
