直流偏置下磁粉材料的磁导率宏观模型

Magnetic powder materials are often considered for inductors used in high-current applications due to their high saturation flux densities and good high-frequency performance. For the design and optimization of powder-based high-frequency inductors, it is important to consider permeability spectra with superimposed dc bias. To include those properties in system-level circuit simulations, compact m...
