Inductors are part of the basics engineers learn in school along with components like resistors and capacitors. Simple, right?
The challenge is choosing the right device for a particular power supply that may include multiple inductors along with other components. Size, cost, efficiency and matching the specs to the design make this a non-trivial engineering task, but one that is quite manageable, especially given the variety of options available. This eBook delves into issues of design efficiency, test and inductor selection.
