Latest Patents
Yamanaga's latest patents include an inductor simulation method and a power inductor evaluation apparatus. The inductor simulation method provides a nonlinear equivalent circuit model that enables dynamic simulation of nonlinear characteristics when a direct current is superimposed with high precision. This method represents the equivalent circuit of an inductor using a series circuit of passive circuit elements. The characteristic change ratios of these elements, when a direct current is applied, are expressed as an approximate function based on actual measurements.
The power inductor evaluation apparatus consists of a storage unit and a determination unit. The storage unit holds the simulation model of a DC-DC converter, which includes the equivalent circuit model of a power inductor. This model incorporates parameters such as the DC superimposition characteristics slope and saturation current. The determination unit inputs these parameters into the simulation model and assesses whether the power inductor meets design requirements based on the simulation results.
