Some time ago I wrote about the “tools in my toolbox,” discussing the various software programs I use in my consulting business (see “A Look in My Toolbox,” IEEE Power Electronics Magazine, December 2014, p.48). That gave me the idea to write about the “books on my bookshelf” (Figure 1) In this age of “Google knows all” I am sure many are wondering why anyone needs books. Quite simply, Google does not know all. Pretty much everything on my bookshelf is not available on the web. One of the disadvantages of web based information is that it tends to be—not always but often—“soundbites” of information rather than an in depth exploration of a topic. Doing a web search for “buck converter design” will return millions of hits. Scanning a selection of the search results shows that most are simplistic application notes that offer formulas that guide component selection. I am sure that these limited discussions are useful to someone or they would not rank high in the search results. However, if one wanted to truly understand the buck converter and how it works I think you would be hard pressed to find the understanding that is available from one of the better textbooks.
