Ouch!
I need another cup of coffee.
Zipons? Truants? Ok....

I downloaded and read the PDF which describes the circuit tested. Which is from October 2002. Looks good at first, until you read carefully, and then it's a perfect example of pseudoscience. Instead of calculating the input energy directly from the measurements of V and I and the V x I waveform, by integrating over time to get the total energy, and then dividing by the number of seconds to get the average power, she does it another way which I don't think is correct or equivalent. I also don't think the measurements are taken correctly, if the diagram actually reflects where and how the measurements were made. And the attempt at calorimetry, while admirable, just serves to illustrate how difficult it actually is to do good calorimetry.

Still, it's a simple enough circuit and I have all or most of the parts on hand. Thanks for a nice little weekend project! We shall see what we shall see.

(I sure hope I don't encounter any Truants or Zipons, though. I get nervous when they get on the same bus I'm on.)

(And darnit, that "patent" seems to be actually a ten-year-old application, not a patent.)

I couldn't find the IRFPG50 specified in the circuit, but I did find some 2SK1548 mosfets that have almost identical specs (900V instead of 1000V). I haven't put it together yet; I might have a chance to later today or tomorrow.
I can see why there is difficulty in measuring this circuit, though--with an input duty cycle less than 5 percent and non-linear oscillations from overdriving the MOSFET, one really needs better equipment than a 50 MHz 2-channel oscilloscope and a spreadsheet.
I have the proper equipment, including fast digital scopes with math functions, and a water-flow calorimetric power meter, but it might be packed away--we're moving to a new undisclosed location and a lot of useful stuff is buried in shipping containers.
But we'll see what I can see with the stuff that's not packed yet, and if there seems to be something interesting I can always dig out the artillery.
