抄録

Ni-Zn ferrite cores under dc bias are experimentally characterized, and the results are compared with those of simulation. Hysteretic behavior of a toroidal core at high frequencies and the effect of dc bias are well reproduced by simulation with a hysteresis model that we have developed recently, a grain magnetics (GM) model. The inductance and core loss of a wirewound inductor under high-frequency excitation with dc bias are also measured. We show that the finite element analysis with the hysteresis model provides simulation results close to the experimental data of the inductor.
