Abstract
A power inductor includes a housing and a magnetic core disposed in the housing. The core includes a first segment and a second segment spaced apart from each other to define a gap. The first and second segments are supported in the housing such that the they are movable relative to each other to increase and decrease the size of the gap. A fluid having a positive thermal expansion coefficient is disposed in the housing such that expansion and contraction of the fluid due to change in temperature increases and decreases the gap, respectively.
