What do you think is wrong with the article?

 

I'm not qualified to judge any aspect of it other than that it was written by the guys with a financial stake in it, and is self published without peer review. Feels a little too good to be true?

Quite possibly. But the author has lots of street cred.

 

The patent examiner bought into it, and I am pretty sure that this is the topology that TI had been touting lately. I have admired Dr. Cük since the early 1980's and am glad that he is still active in the field.

Agreed, and that makes me hopeful this is more than a dream.

Not identical but similar.

Edit: I take it back. Same topology.

 

That's new to me....but I'm not much of a power guy. It is very interesting. I found this.....January 1987.
