Rosemary Ainslie Quantum Magazine Circuit COP > 17 Claims

[poynt99]

Ashtweth from Panacea was good at compiling information from a project. And although Panacea's website is no longer, the internet never forgets, and I was able to find Ashtweth's large compilation pdf of the work Glen was doing back in 2009. I uploaded it to TK's mediafire account. It is 15M in size and contains 290 pages. All Glen's tests and images are in this document, as well as a lot of other stuff. Test #13 starts on page 197.

OK,

I've found all the Test data and images from Glen's work (22 tests) on his own skydrive site here:

...and Glen's livestream site that links to the above (links are near bottom of page):

Here are posts where Glen notes a few mods, including a 15k to replace the 10k trimmer to achieve the 3% duty cycle.

You make it sound like replacing the 10k trimmer was the only, and a trivial, modification. But that is not the case. FTC was modifiying AARON's circuit, which had already been much modified from Ainslie's three published claimed circuits. The link in the forum post you cited takes you to the Aaron circuit.

You will note that in Aaron's circuit, almost all the component values have been changed from the original values. FTC changed the 10k to a 15k IN THIS CIRCUIT, not the original posted by Ainslie.  Further, Mark E has tested the AARON circuit and determined that it too cannot make short duty cycles as diagrammed.

I don't know if adding 5 k of resistance could make the difference. Have you simmed this version to see if FTC is correct?

Where is the recirculation diode that appears in the EIT paper's version of the schematic?

TK,

I am not trying to make it sound like anything in particular. I simply restated what was posted in that link.

I have not checked Aaron's schematic nor Glen's update to any great depth. I did notice that Glen's updated schematic doesn't show a 15k trimmer pot.

I have simulated the original Quantum circuit. I used Groundloop's circuit and circuit board for my own testbed.

The data from Test #13 is the one they chose to use for the IEEE paper submission, as it showed the most "benefit" as I recall. The images from all the other tests would be nice, but Fig. 4 and Fig. 6 from Test#13 are really the only ones required, as they show the gate drive (CH3) (close to 50% duty cycle and between 200kHz to 400kHz frequency), Vcsr (CH1), Vbat (CH4), and Vdrain (CH2).

Attached is the "100ns" scope shot for that test (Fig. 6 in the IEEE submission).

ETA: Now that I've found Glen's cache of data, here also is Fig. 4:

Channel 2, the BLUE trace, is the Drain trace.  Right? And it is DC coupled in those shots, right?

What is the voltage expected at the DRAIN when the mosfet is OFF, and what is the voltage expected at the DRAIN when the mosfet is ON?

Both of the FTC shots you present show a LONG ON duty cycle and a short OFF time.  You can clearly see this in the behaviour of the Current trace, CH1 Yellow, and in the Drain trace, CH2 Blue. The Gate trace is SET to about a 50 percent duty cycle but because of the slow fall  time of the gate signal and the slow mosfet response, the Gate of the mosfet does not turn off at 50 percent but stays on much longer. The true duty cycle at the mosfet DRAIN... hence the current through the load.... is more like 60-75 percent or more ON.

The nice spike in the DRAIN trace is the mosfet turning OFF !!!

Also, Glen appears to be operating at over 400 kHz.

So he's using a different circuit than Ainslie ever claimed, not even one of the three she claimed, and he's operating at a vastly different frequency, 400 kHz rather than the 2.4 kHz she claimed.  SO what has this got to do with Ainslie and her claims?


And as I have just proven on my setup, driven by a FG, these settings produce a mosfet that is almost always ON, and I get a load current of a bit over 1.5 amps with Vbatt = 24 volts.
