Go to Dr. Ray Ridley's Ridley Engineering site and look at the page listing his publications and a short description of each one. The paper described at the very botom is  a hoot. Here is part of the description:

This is at the bottom of the list for a good reason. An interesting paper, it seems to make a lot of sense. Unfortunately, for current-mode control, most of it is wrong, due to an early error in modulator gain! ..................... Don't read this paper unless you are particularly curious. The best lesson contained in this paper: don't believe everything that you read, publication is not necessarily an indication of accuracy.

Mind you, he is referring to a paper published in the IEEE Transactions on Power Electronics. Apparently none of the reviewers caught the mistake.
