Abstract
A magnetic component with hysteresis is modeled as a network of field-based elemental subcircuits, whose currents and voltages are related to the dynamic electromagnetic fields in the component and an interface network, which couples the terminal voltages and currents to the field-based network. Such a model captures rate-dependent hysteresis, geometry, frequency and waveshape effects. Coupled transient simulation of the electromagnetic fields inside the core and circuit phenomena has been demonstrated using the Saber circuit simulator. The low-frequency inductances and hysteresis-related waveforms predicted by the model have been verified experimentally.
