The following design examples contain various techniques to improve the
overall efficiency of common designs. Most of the designs of active clamps and
lossless snubbers are empirical, so they are not included within these design
examples.
Care must be taken in using the new techniques because of the patents that
cover many of their uses. There may be a licensing fee that needs to be paid
directly to the patent holder or a small per-piece fee that is paid when buying
the control IC. Please investigate this before introducing these power supplies
to production.
