Keywords:current inductor? effects DC? switching supply?

The design of the main power inductor in a switching power supply provides many challenges to the engineer. Not only must an inductance value be chosen, but also how much current the inductor can handle, the winding resistance, mechanical factors etc. This article looks at one of these considerations: understanding the effects of DC current on an inductor. It provides some of the background necessary to making an informed selection of an inductor.
