ABSTRACT
The design of an inductor also frequently involves consideration of the effect of its magnetic field on devices near where it is placed. This is especially true in the design of high-current inductors for converters and switching regulators used in spacecraft. Molybdenum Permalloy Powder Cores are manufactured from very fine particles of an 81% nickel, 17% iron, and a 2% molybdenum alloy. The insulated powder is then compacted into EE and toroidal cores. The low cost iron powder cores are typically used in today’s low and high frequency power switching conversion applications for differential-mode, input and output, power inductors. The distributed air gap characteristic of iron powder produces a core with permeability ranging from 10 to 100. Inductors that carry direct current are used frequently in a wide variety of ground, air, and space applications. The design of an inductor also frequently involves consideration of the effect of its magnetic field on other devices in the immediate vicinity.
