The magnetic elements form the backbone of the switching power supply’s
operation. Understanding their basic operation, and the practical tradeoffs
during their design is crucial to the entire power supply’s proper operation.
Factors such as efficiency and reliability are highly dependent on the magnetic
component’s design.
Unfortunately, the typical engineer’s college curriculum only includes about
a course and one-half of magnetism-related theory, which is easily forgotten.
The purpose of this appendix is to refresh your memory with some magnetic
theory highly slanted to switching power supply applications. ...
