Abstract
A power inductor evaluation apparatus includes a storage unit and a determination unit. The storage unit stores the simulation model of a DC-DC converter. The simulation model includes the equivalent circuit model of a power inductor, including a DC superimposition characteristics slope α and a saturation current Isat as parameters. The determination unit inputs the DC superimposition characteristics slope α and the saturation current Isat into the simulation model of the DC-DC converter and performs simulation, and determines whether or not the power inductor having the DC superimposition characteristics slope α and the saturation current Isat is usable on the basis of whether or not the simulation results satisfy design requirements (e.g, a permissible ripple voltage and a peak current).
