Switchmode Power Supply Handbook, Second Edition

The design of the switchmode transformer, more than any other single factor, will determine the overall efficiency and cost of a modern switchmode supply, Unfortunately, the transformer design process also tends to be the most poorly understood area of switchmode design.
The intention of this section is to throw some light on the major parameters which control high-frequency transformer design. The subject is vast, and many volumes have already been devoted specifically to it. It is beyond the scope of this book to deal with more than some general aspects, but these are covered in sufficient detail to allow the production of working prototypes which will not be too far from an optimum design.
Expert transformer engineers will already be familiar with the many volumes available on the subject, and will be using one of the more sophisticated core geometry, area product,...
