Maybe Dr S Cuk will not agree. BTW, I almost got the chance to
see him personally when I was in Irvine last time. Anyway my
supervisor back in UC Irvine is his student in Caltech.

One of the major problem was (no so sure if it still is) that Cuk
topology is patented by Cuk. Therefore not many people would
like to use it. The design of Cuk converter, especially the
Magnetics part is not easy. I had a friend who did some study
on Cuk converter based Power Factor Correction circuit and
she told me it was not fun at all...
