Re: The Unitrode seminars legacy
Indeed, Lloyd Dixon deserves being inthe E.E. Hall of Fame, if there were one.

He has derivations of equations in some of his articles, but it has been left to me and others to bore the reader with a multitude of equations. When I do it, I try to indicate which are the useful design formulas so that math-averse readers can scan past the derivations and read how to apply the resulting formulas.

And for those who want a deeper understanding of where the equations came from and how they came about, the derivations are there. I encourage this deeper understanding because design formulas can be misused as a consequence of not knowing the conditions under which they apply or exactly how they apply. And for those wanting to Lead the Field in E.E., depth at both the desk and the bench are required to understand how clear theory and real circuits relate.

The Unitrode seminars legacy
I have attended a number of Unitrode seminars in previous years. One time I sat beside Lloyd H. Dixon, one of the major contributors of the early seminars and author of many papers that can be found in the seminars booklets. At that time, I was, and I am still, very much impressed by Dixon's ability to bring up the gist of the matter in an intuitive way without wearing out the reader with pages and pages of equations. While chatting with Dixon I have complemented him on his very clear and reader friendly papers. He responded in saying something like: " I see as my duty to explain what is written in all these journal papers". For many years now, I have adopted this intuition-based-knowledge approach and I believe that my students and readers of my papers benefited from that.

 It is indeed good news that TI is continuing the tradition of the power electronics seminars to the benefit of the engineering community.

Re: Well done Steve!
Thanks @bcd_testech---I highly recommend these seminars because of the in-depth educational value they provide to designers, no matter the level of experience they have. The presenters are experts in their own right as well. I always learn things from these kinds of excellent seminars.

Well done Steve!
Greatly appreciated. I attended one of the SEM500 sessions back in (gulp) 1987 and was super impressed by the methodical approach to numerous topics, such as transformer wire temperature, that I'd viewed as half rule-of-thumb, half black magic. I had no idea TI was still holding the seminars, much less that the material would be available online.So your article is nearly as much of an eye opener as the original seminar.
