摘要
The finite element (FE) modeling of a ferrite-core device is discussed. Measured properties of Ni-Zn ferrite ring cores show that even though the AC ferrite property is similar to that caused by the eddy-current field, the FE eddy-current analysis using an equivalent electrical conductivity cannot, in practice, represent the AC property. An equivalent-circuit model which describes AC/DC ferrite properties is applied to FE magnetic field analysis of a ferrite-core inductor. The simulated AC property with/without DC bias agrees with the measured one.
