Testing the TK Tar Baby

[poynt99]

@All,

Did some testing on the oscillation cycle.

TEST OF BIAS CURRENT IN OSCILLATION MODE:

With Q2:
Main Input: 24 Volt @ 0,17 Ampere = 4,98 Watt.
Bias Input: 12 Volt @ 0,17 Ampere = 2,04 Watt.

Hang on a second here GL, something is wrong; check your numbers again for the Main Input calculation. 

24V x 0.17A = 4.08W, not 4.98W. I think you mistakenly hit the "9" key instead of the "0" key when you were typing.

So, it holds. 1/3 of the total power is contributed by the FG (in this case with 12V and 24V supplies).

And HERE Stefan is another MISREPRESENTATION. TK states that...

>> And here is a good time to point out: THERE HAS BEEN NO EVIDENCE AT ALL that shows high heat WITH OSCILLATIONS ONLY. All of the Ainslie data showing high heat in the load has used a bipolar pulse with substantial current evident during the NON OSCILLATION mode: high current flowing through the single Q1, NOT the gang of 4 Q2s, if the schematic in use was the one which Ainslie has repeatedly affirmed is correct.

The final 10 minutes of the 'water to boil test' showed ZERO current flow during the 'on' period of the duty cycle - with the heat at a 'runaway' level that we discontinued the test in the interests of safety.  And at the conclusion of that test had NO need to change any of the MOSFET transistors.

Therefore this statement is yet more evidence of the spin that TK relies on to contradict our claim

I believe we have changed one MOSFET subsequent to that test.  It occurred after the incident where the batteries caught fire and was not a consequence of any transistor degradation from that 'water to boil' test.

I've relabeled GL's diagram to correspond with the usages we have been using here.

Could you please check, GL, to see if I've done this correctly? Thanks... I hope you don't mind my edits and that they are correct in making your diagram correspond to mine and Ainslie's.

PROVE IT.

It is impossible for a mosfet that is functioning properly to receive a +10 or +12 volt positive gate drive and NOT turn on and pass current. Stefan knows this and so does everybody else who has ever used a mosfet. Except maybe Ashtweth and Aaron.

You blew a mosfet in that trial and SINCE THEN you have NEVER used a long duty cycle with a 72 volt battery pack and a long ON time for Q1. And I know why and so do your collaborators, even if you don't.

TK,

GL's diagram is essentially the same as mine (attached). He is still calling Q1 "Q2" and vice versa according to Rosemary's First paper diagram though. I've not shown Q1's diode because it has no effect to the measurements in my simulation.

The conclusion from GL's test is this:

The FG contributes power to the circuit, which is half as much power as the battery supply (in this case), while the circuit is in the "negative bias" oscillation mode of operation.

I agree and I thank you both for your work. But can we PLEASE agree on the designations? In the NON-oscillation mode it makes a big difference whether one mosfet or four are carrying the larger DC current, and I still contend that it is this mode that makes the high heat in Ainslie's trials.
