Power inductor evaluation apparatus and power inductor evaluation program

A power inductor evaluation apparatus comprising:

• a storage unit storing a circuit model that includes an equivalent circuit model of a power inductor and simulates a Direct Current to Direct Current (DC-DC) converter, the equivalent circuit model including a Direct Current (DC) superimposition characteristics slope and a saturation current as parameters;
• a reception unit receiving input of the DC superimposition characteristics slope and the saturation current of the power inductor to be a determination object and input of a requirement including at least one of a permissible ripple voltage and a peak current;
• and
• a determination unit that performs an arithmetic operation by inputting the DC superimposition characteristics slope and saturation current received by the reception unit into the circuit model of the DC-DC converter including the equivalent circuit model of the power inductor and determines whether or not the power inductor having the DC superimposition characteristics slope and saturation current is usable on a basis of whether or not a result of the arithmetic operation satisfies the requirement thus providing a basis for power inductor optimization based upon DC superimposition characteristics slope and/or saturation current margins.
