Use PSpice to model distributed-gap cores

摘要

PSpice software lets you create magnetic-core models that simulate nonlinear magnetic devices (Figure 1). These simulations are useful for observing hard-to-measure magnetic parameters such as core flux density, especially when you cannot quickly procure a sample device. The required inputs to the PSpice magnetic-core model are initial permeability of the core material, data points from the B-H magnetization curve, and the physical properties of the core, such as magnetic-path length, cross- sectional area, and air-gap length.
