Rosemary Ainslie COP>17 Circuit / A First Application on a Hot Water Cylinder

[happyfunball]

Cut the garbage, it's Rosemary's circuit.

It's her circuit, Fuzzy. Cut the crap already.

With all due respect happyfunball, you will find the same circuit outlined here in Fig 12a:
http://www.datasheetcatalog.org/datasheet/irf/irfpg50.pdf

That PDF has a date of 10/97.

However, The HEXFET Power MOSFET Designer's Manual HDM-3 of which I have in my library, has the exact same circuit and is dated September 1993. You will also find that document included in the references in my work used in the paper.

The record clearly shows the circuit to be in the public domain at least five years prior to Rosemary filing her first patent application.

No one is trying to steal anything, it is already available for everyone to use and has been for over 17 years now.

I won't debate the merits of your claims, since they're irrelevant. Why? Because Rosemary is open sourcing the entire thing. Why not let her test the circuit and theories and perhaps even thank her.

My version is even older, and is before the IRFPG50 was born:

Power MOSFET HEXFET Databook, HDB-3, 1985. It does not seem to have the unclamped diagram in any of the spec sheets, but it does reference avalanche testing using essentially the same circuit as Fig. 12a. in the "Integral Body Diode" section, App note 934B, Fig. 23.

All that happened in this whole saga is people did not listen to creditable hard workers in the open source community  and made a fool out of themselves. we know who you are now. I am glad this is over, we told you so, all as it did was unnecessary distract engineers from work.
now we can get on with the job with out the you know whats.
